"Wasting Seed" - Differing Rabbinic Perspectives

What do rabbis have to say about the sin of wasting seed? Well, if you're searching the internet to find the answer, you're likely to come across the self-proclaimed leading expert on this topic, Rabbi Yaron Reuven. (As you may recall, we last saw him insisting that Hitler was justified in blaming the Jews for ruining Germany, and declaring that numerous widely-respected rabbis are heretics who deserve to be executed.) He is certainly obsessed with the topic of wasting seed, and has over thirty hours of lectures about it!

In a lecture that you can watch on YouTube, Reuven notes that the Talmud compares wasting seed to murder, and he takes this very literally. Incorporating the modern scientific revelation that ejaculate contains around 300 million spermatozoa, he rails against teenagers who masturbate, claiming that they are mass-murderers who are killing as many people as the entire population of the United States! He also stresses the Zohar's claim that wasting seed is worse than any other sin.

Reuven's mentor/colleague Rabbi Yosef Mizrachi also has a lecture about this topic on YouTube. He presents the "kabbalistic secret" that all the souls in the spermatazoa were supposed to enter this world, but instead are doomed to remain in the netherworld, waiting to confront the teenager after his death and seek revenge. "You have millions of sons now," he says, "and they all hate you!"

It's not clear to me how Reuven and Mizrachi reconcile all this with the fact that even with intercourse resulting in pregnancy, 299,999,999 spermatozoa do not result in life (not to mention that intercourse with one's already-pregnant wife is permitted). But what is clear is that such presentations cause immense psychological harm to countless teenagers. In fact, in a FaceBook group of people giving their stories about why they left Orthodoxy, more than one mentioned the severe psychological harm caused by the belief that masturbating meant that they were irredeemably damned; there is also a powerful personal story at this link

As discussed in an earlier post, "Sexual Intimacy, Spilling Seed, and the Rationalist-Mystical Divide," there are much more prestigious rabbinic authorities who take a very different approach. Rav Eliezer Melamed says that the fire-and-brimstone expressed by the Zohar against spilling seed in vain is simply an exaggeration (and of course there are others who simply dispute the authority of the Zohar altogether). Rav Melamed further points out that the Talmud's severe-sounding comparison of spilling seed to bloodshed is a rhetorical flourish, noting that the Talmud says the same about someone who embarrasses others in public or who does not escort his guests out. As Rabbi Yaakov Shapiro notes in his excellent book Halachic Positions, the same interpretation of such condemnations in the Talmud is given by Rivash, as well as by an early Acharon, Rav Yehoshua Heschel of Krakow, specifically in this context. There is also much fascinating discussion of this topic at, and there's a podcast by Rabbi Scott Kahn and Talli Rosenbaum at

I would like to also counter the Reuven/ Mizrachi approach with two other presentations. One is an article in Hebrew by Rabbi Yitzchak Rones, available online at this link. The other is a controversial article by Rabbi Avraham Stav which appeared online in Hebrew. A friend of mine translated it, and I present it here:

What I would like to say to a maturing young man:

1. The human body produces sperm cells at a fixed rate of around 1500 new cells per second, and it tends to dispose of the old cells in various ways, during sleep (nocturnal emissions) or ejaculation (masturbation), generally (though not solely) in response to sexual stimulus.

2. According to what we know today, masturbation is an activity that is not harmful to one’s health; from a psychological perspective too it is considered (within reason) to be a natural and normal part of sexual development. This should remove the fears and unwarranted concerns regarding the issue that have been refuted over hundreds of years.

3. The Torah and Prophets do not discuss masturbation explicitly, and the first time it appears as a sin is in the words of Chazal. There is a substantial dispute as to whether the Sages believed that it is biblically forbidden or whether they only forbade it rabbinically.

4. The verses to which Chazal attached the prohibition (such as the actions of Onen who “destroyed on the ground” his seed) hint to this relating, at root, to masturbation by a married man (mainly at times when fruitful marital relations are possible), which substitutes for relations between the couple and directs his sex drive away from the couple relationship and from the mitzvah of “be fruitful and multiply” towards self-gratification.

5. In many sources, wasting seed is treated extremely seriously, and we do not know why. It is possible that this stems from a restrictive approach to the entire realm of sexuality, which exists in some of the sources. Alternatively, it may relate to the deep trend of egoism and “waste” that is expressed in masturbation when it becomes an integral and central part of life and comes at the expense of constructive activity. Nevertheless, there are sources indicating that a specific act of masturbation is a relatively light sin.

6. In practice, the vast majority of males, at one stage or other of their lives (mainly, but certainly not exclusively, during the youthful period), masturbate. Included in this are Jews who observe mitzvot and fear heaven. This increases when there is a large gap between the stage of reaching sexual maturity and marriage.

7. In front of every person, and in front of every young man, stand many spiritual challenges, and reducing masturbation is one of the less important ones.

8. The constant struggle against masturbation only strengthens, incorrectly, its place in life. One should be concerned that it not turn into an obsessive addiction, but should also not relate to each instance as a “fall”, and not dedicate one’s religious and spiritual energies to hopeless battles. On this point, there are likely to be differences between different people, who are found in variant places spiritually, and personal guidance on this matter is beneficial.

9. Masturbation in most cases accompanies sexual stimulus, and specifically visual stimulus or fantasies. Enjoyment from the sight of the naked body (real, virtual or imagined), is a natural and healthy inclination, which exists among most humans, and there is no reason to be ashamed of it. At the same time, this is a superficial stimulus which is supposed to serve the more elevated and meaningful goals of connection between a couple and having children.

10. Due to the power of superficial, external, sexuality, and because of its ability to occupy a large proportion of one’s life and to lead to a variety of negative phenomena, one should desist, as much as possible, from gazing at sights which bring about sexual arousal. It is important to distinguish between masturbation in itself, which is a natural inclination which comes from the body and its desires, to external sights which frequently represent other worlds of culture and values.

11. There are also various levels within the realm of the forbidden. Masturbation without forbidden gazing is far preferable to masturbation that is accompanied by such gazing, and there is a meaningful distinction between gazing at a generic immodest picture to surfing the world of pornographic content, which brings with it a long list of severe consequences in terms of the conception of the body and of sexuality and is also bound up with many moral problems. Within the realm of fantasizing too, there are thoughts of sin that are more severe than others, whether from a halachic or a moral perspective.

12. Judaism seeks to sanctify the sex drive, to refine it, to lead it to constructive and positive places. Not to fight it. Spiritual work in the sexual realm is positive and beneficial as long as it makes a person more exacting and elevates him; and it misses its goal when it causes him to be more imprisoned within himself.

This was written following extensive discussions with senior rabbis and professionals.

Whether or not one agrees with Rabbi Stav's approach, it is certainly important for there to be countering perspectives to the dangerous extremism broadcast by Reuven and Mizrachi.

Yated's New Low

Over the years, I've seen some pretty bad behavior in the name of frumkeit. But this one hit me so hard that my hands are literally shaking as I write this.

There's a letter in this week's US edition of the Yated Ne'eman, in the "Questions and Answers" column.

It's signed by Rabbi Dr. Natan Slifkin.

But I never wrote it! 

A person at Yated fabricated a letter and put my name on it.

The guilty party at Yated is a (former) old friend of mine, who writes the "Questions and Answers" section, with the assistance of other rabbis. I've been discussing/ arguing with him over the last few weeks about the topic of paying someone to learn Torah and transferring the reward to the nominee of one's choice. So he decided to compose a letter to the Yated, purporting to present my position in a way that he deemed fit, and to sign my name to it!

Although he no doubt sincerely intended to present my position accurately, he did not actually do so. Most egregiously, he fabricated a statement from me accusing organizations that fundraise in this way of having a "lack of integrity" in going against the Rishonim. But I never said that going against the Rishonim displays a lack of integrity. My argument was that according to traditional Judaism, such a merit-transfer mechanism just doesn't work.

I was stunned that this person thought that it was ethically acceptable to fabricate a letter in my name, assuming that I would want to have a letter printed and creating the content for it. I wrote a furious email to him, and he replied that he does it all the time and doesn't see anything halachically wrong with it!

What makes it especially ironic is that several months ago, when this rabbi reported a position of Rav Zalman Nechemiah Goldberg ztz"l that seemed rather unethical, with regard to a son being told to disregard his father's dying wish, I wrote a post in which I suggested that perhaps this rabbi had "processed" Rav Zalman Nechemiah's words (or the question that was posed to him) in a way that did not accurately reflect the truth. The rabbi was very upset by this accusation, and insisted that he reported Rav Zalman Nechemiah's position accurately. Well, now that I have first-hand experience with this rabbi misrepresenting my own position and fabricating words in my name, I see that there is no reason to consider him at all reliable, both in how he reports the questions that he receives to the Rabbonim, and in how he presents their responses.

If you're thinking, "Well, he's clearly a bad person," then you're mistaken. He is a really, really nice, sweet, sincere, temimusdikke person, who has the best of intentions, and who even wants to get the charedi world to respect me (he may have wanted to show that I am "kosher" by having my name printed in the Yated, complete with honorific). But he's a product of a sector of Orthodox society in which there is a severe lack of professionalism. This is coupled with a serious deficiency in intellectual honesty (defined as "honesty in the acquisition, analysis, and transmission of ideas"), along with a problem of arrogance regarding the Truth and value of one's own interpretation of one's cause. That's why Dr. Marc Shapiro was able to compile an entire book full of examples of rabbis censoring and misrepresenting the positions of rabbis from earlier generations that they claim to respect. And that's how they see no problem in telling a person, whose dying father had asked him to donate from his estate to conservation and not to a kollel, to instead give it to a kollel.

With regard to the response that the rabbi gives to "my question," in the names of Rav Azriel Auerbach and Rav Goldberg, it is deeply problematic. The response notes that the Rokeach says that such a merit-transfer works, on the (very difficult) grounds that Hashem knows that if the deceased were still alive, he would have given the charity. And they proceed to say that this "is the accepted halacha... Once the Shulchan Aruch and the Rama, the two amudei hora'ah, have ruled, then you can pile up Rishonim from here to the moon and it is of absolutely no consequence. The accepted halacha determines the belief and practice of Klal Yisroel, and therefore the deceased most definitely receive reward for tzedakah given in their name."

It's rather bizarre that the notion of Judaism being based on broad ancient traditions is so casually thrown out of the window. But there's another fundamental problem here. What on earth does "halacha" have to do with this? This isn't a halachic matter! The question of whether one can transfer the reward for a mitzvah to somebody else is one of metaphysical reality, not legal practice! You can't pasken whether the world is flat or spherical, you can't pasken where the sun goes at night, you can't pasken whether or not demons exist, you can't pasken how Hashem decides to run His relationships, and you can't pasken whether or not reward for mitzvos is something that is potentially transferable! 

Furthermore, the Rokeach, difficult as his position is, does not even go remotely as far as they are taking him. He is justifying the ancient custom to give charity on behalf of the dead for Yom Kippur, which he relates to the concept of atonement. But, as several authorities point out, charity is only being mentioned here as being pledged on Yom Kippur (Rokeach explicitly says that it is not done on Chag, and Rama states that it relates to the particular status of Yom Kippur), as a way to save a person from punishment, not as a way to actively provide reward to someone in the next world. Furthermore, it is specifically charity that is mentioned, not any other mitzvah such as learning Torah; it's the exception that proves the rule. (And note that the Rokeach says that it helps "ketzas", which the translation given in the Yated somewhat inaccurately renders as it "does provide some benefit.")

The Rokeach/ Shulchan Aruch/ Rama do not say that you give charity at any time and transfer the reward to anyone you choose. And they do not say that you can give money to a yeshivah and transfer the merit for that Torah study to the person of your choice. And in any case, the actual truth of what happens is an independent metaphysical reality, not something that can be "paskened"!

I'd love to write to Yated to point this out. But I won't. Because I'm not interested in writing any letter to a publication that sees nothing wrong in fabricating letters that they attribute to people. (And the irony is that the actual letters that I really did write to the Yated over the years were not printed!)

Pigs In Shtreimels II

Four years ago, there was the notorious rally in the Jerusalem Arena for Beis Yaakov girls. The purpose of the rally was to dissuade them from attending any of the numerous academic higher education programs for charedim that have sprung up in recent years. Rav Baruch Shapira introduced the program by relating a conversation that he had with Rav Steinman about the event. Rav Steinman said, "Charedi academic programs?! It's like a pig in a shtreimel!" (See my post about the event, which summarizes the messages from the speakers.)

Well, now there is a new campaign against the pigs in shtreimels. A prominent Rosh Yeshivah, Rav Yigal Rosen, declared that he has launched an initiative in his yeshivah, which he hopes will be emulated by others. If a student marries a girl who is enrolled in a charedi academic program, then neither the rabbis nor the students are allowed to attend the wedding.

As I wrote in my previous post on this topic, it is indeed true that once a person steps out of the daled amos of the yeshivah or Beis Yaakov, they are exposed to all kinds of influences and ideas that run contrary to charedi and Torah values. But on the other hand, im ein kemach, ein Torah. We have to earn money, work, and build up society. If charedim are going to radically diverge from tradition by sending everyone to kollel, then the women have to shoulder the workload of both partners (while also giving birth and raising children). And it's just not possible for charedi society to accomplish that if the women only attend Beis Yaakov. It will just accelerate how charedi society is trying to lead itself, and ultimately all Israel, to economic ruin

He Says I Was Wrong

In my article on what one can do for someone who has passed away, I told the following story:

"A friend of mine told me that when he was studying in the yeshivah of Rav Tzvi Kushlefsky in Jerusalem, a student once asked if Rav Kushlevsky could dedicate that day’s lecture to elevate the soul of his grandmother. Rav Kushlevsky replied that this was impossible; while his delivering the lecture would be a credit to his own grandmother, there was simply no way by which to transfer that credit to someone else’s grandmother, who had no role in enabling the lecture to take place!"

A few weeks ago, Rav Tzvi Kushlefsky's yeshivah, Heichal HaTorah, ran a 1.2 million dollar fundraising campaign. It promised that if you donate $500 or more, they will "arrange for a masechta to be learned as a zechus/l'iluy nishmas the person of your choice."

Now, obviously nobody wants their $1.2 million campaign to lose its appeal. But surely this a direct contradiction to the clear position of the Rishonim that there is simply no way of transferring reward to a random person who did not earn it. And the Rosh Yeshivah himself acknowledged that it doesn't work! So I was convinced that whoever created this fundraising campaign had not discussed it with Rav Tzvi.

I don't know Rav Tzvi personally, but his late brother was one of my late father's oldest friends, and his late sister was Rebbetzen of my childhood shul. And I do know one of the rabbis in his yeshivah. So I reached out to this person for clarification. Eventually I received the following response:

"I spoke to Rav Tzvi Kushelevsky this Shabbos. Just to make sure that there was no misunderstanding I asked 3 times using different wordings. He said that if someone gives tzedaka or learns in someone else's memory it definitely helps the neshamah of the deceased. Since this would not have came about without the impetus from that person – it is considered a zechus for them. The confusion probably comes from the case where you quote - where someone was already giving a shiur. In such a case it does not help to do it in their memory since they were not the cause."

So, I can no longer claim that Rav Tzvi Kushlevsky supports the traditional position of the Rishonim (which is also seen in Chazal). I must also explain why, in my view, the Rishonim did not allow for such a possibility. If you are paying for Torah study (assuming that this is considered charity), then it is *you* that is the cause of the good deed, not the random person that you nominate to receive the reward! It might be that your grandmother inspired you to be charitable, and it could be that she gets credited for that - but she didn't inspire a complete stranger to learn Torah! (And if you're going to claim that a person gets the credit for anything that results from them, even if they didn't inspire it, it would mean that Haman gets credit for all the mitzvos of Purim!)

I will conclude by again quoting the Rishonim, whose words are unambiguous, and who rejected any possibility of arranging to transfer reward to someone else. Since the statements of the Rishonim are omitted from all contemporary yeshivish discussion of this topic, and are ignored by everyone, they can't be quoted often enough.

"There is no doubt that what one person does for another after their passing is of no benefit or aid, for each person is judged according to what they are at the time of their death. In accordance with the person’s level and attainments at the time that his soul departs from his body, so will he attain elevations and merit light with the Light of Life, and there is no additional elevation or benefit in that which others do afterwards to benefit him…" (Maharam Chalavah, Responsa, #17)

"A person cannot merit someone else with reward; his elevation and greatness and pleasure from the radiance of the Divine Presence is only in accordance with his deeds. Even if all the righteous people in the world were to seek mercy for him, and all the righteous acts were to be done in his merit, it would be of no help to him…" (Rashba, Responsa, Vol. 7 #539)

"These concepts are nonsense and one should not rely upon them. How can one entertain the notion that the reward of good deeds performed by one person should go to another person? Surely the verse states, “The righteousness of a righteous person is on him,” (Ezek. 18:20) and likewise it states, “And the wickedness of a wicked person is upon him.” Just as nobody can be punished on account of somebody else’s sin, so too nobody can merit the reward of someone else. How could one think that the reward for mitzvot is something that a person can carry around with him, such that he can transfer it to another person?" (Rav Hai Gaon cited by Maharam Alashkar, Responsa #101)

"How can the merits of Reuven be of benefit to his brothers Shimon and Levi? What could his mitzvot do for them?!" (Responsa Binyamin Ze'ev 202)

I think that the truth of what the Rishonim write is obvious. But, as I wrote in yesterday's post, there are both noble and less-noble reasons for people to convince themselves otherwise. And unfortunately, while it can lead to benefits in terms of fundraising for important projects, it can also lead to negative consequences.

Buying Salvation

The history of Christianity has profound lessons for Jews.

If you were a Christian in the medieval period, and you had sinned (as we all do), what was there to be done about avoiding punishment in the afterlife? A priest was empowered to grant God's forgiveness and thereby prevent eternal damnation, but that wouldn't remove the need to "do time" in purgatory. 

The Church therefore also provided the opportunity for "indulgences." The debt still owed for forgiven sins could be removed by contrition, confession and good deeds. Suitably qualified priests would decide exactly how much of these were necessary to cancel the debt for each sin.

Now, the good deeds that were required were sometimes too challenging for people to fulfill. For example, making a pilgrimage to Jerusalem was very difficult before air travel. But that was easy to solve - the popes offered the alternative solution of enabling other people's good deeds instead. You could give money towards building a church, and attain redemption from punishment that way.

But what if you wanted to obtain redemption on behalf of someone else, who had already passed away and was suffering in purgatory? In 1476, Pope Sixtus IV provided a solution for that too: you could gain an indulgence for them by giving money on their behalf. The German friar Johann Tetzel put this into highly successful practice. He made potential buyers "feel guilty if they did not seize the opportunity," reminding audiences of their parents and ancestors "clamoring for help" in purgatory and needing just one donation to send them into paradise.

It's not difficult to see where the theology of indulgences led. Instead of people having to actually improve their ways, they could just buy their way out of purgatory. And they felt that they could help their loved ones by buying redemption for them. And various theologians actively encouraged this, because they were financially benefiting from it. All this inevitably snowballed into a mountain of greed and corruption. 

Finally, Martin Luther reacted by launching the Protestant reformation. Forced to respond, the Catholic church ruled that it was forbidden to provide absolution via taking money for good causes.

It's not that there is anything wrong with people giving to charitable causes - far from it! But once you provide for repentance to be outsourced, and you monetize it, this inevitably results in three problems. 

One is that people stop feeling the need to actually become better people. Why go through the great difficulty of changing your ways, if you can just write a check to get the same results? And consequently, rich people achieve greater spiritual benefits than the poor!

The second problem is that ecclesiastical authorities who need funds are motivated to devise theologies and campaigns to encourage people to obtain redemption via giving money to them. They are not necessarily bad people. But "bribery blinds the eyes of the wise, and corrupts the words of the righteous" (Devarim 16:19). Note that the Torah doesn't say that it corrupts regular people - it says that it corrupts the wise and righteous. It's noble to want to help people who have passed away, and it's natural (and sometimes noble) to want to build up institutions. The combination of the two is a powerful incentive to devise a supporting theology. Thus, theology becomes motivated by factors other than determining truth.

The third problem is that once this theological mechanism has been created and embellished, it's all too easy for charlatans to take advantage of it. And there can be many different levels of charlatans, not all of whom are outright frauds. It's not just about hassidic rabbis and kabbalists becoming millionaires. It's also about manipulative behavior with fundraising, born of the desperation to support families of unemployable kollel students.

Outsourcing and monetizing salvation is bad theology, and a recipe for corruption. But the motivations behind it are a potent mix of both noble and less noble desires. This is what enables people to dispute or consciously ignore the clear statements of the Rishonim:

"There is no doubt that what one person does for another after their passing is of no benefit or aid, for each person is judged according to what they are at the time of their death. In accordance with the person’s level and attainments at the time that his soul departs from his body, so will he attain elevations and merit light with the Light of Life, and there is no additional elevation or benefit in that which others do afterwards to benefit him…" (Maharam Chalavah, Responsa, #17)

"A person cannot merit someone else with reward; his elevation and greatness and pleasure from the radiance of the Divine Presence is only in accordance with his deeds. Even if all the righteous people in the world were to seek mercy for him, and all the righteous acts were to be done in his merit, it would be of no help to him…" (Rashba, Responsa, Vol. 7 #539)

"These concepts are nonsense and one should not rely upon them. How can one entertain the notion that the reward of good deeds performed by one person should go to another person? Surely the verse states, “The righteousness of a righteous person is on him,” (Ezek. 18:20) and likewise it states, “And the wickedness of a wicked person is upon him.” Just as nobody can be punished on account of somebody else’s sin, so too nobody can merit the reward of someone else. How could one think that the reward for mitzvot is something that a person can carry around with him, such that he can transfer it to another person?"

The Challenge of Eagles and Hoopoes

There's a Torah-science challenge that you've never heard of. In fact, I think that nobody has ever thought of it before. But it's been bothering me for years. In this post, I will discuss it, and suggest a path towards reconciling with it. 

The laws of kashrut that were introduced in Parashat Shemini are repeated in this week's parasha, Re'ay. With land animals, we are given signs for identifying kosher animals - a system that we can use thousands of years later to identify newly discovered species such as okapis as being kosher. With fish, we are likewise given signs, which we can easily utilize to identify kosher fish at markets anywhere in the world. Even with insects, while it is a a little more complicated, there can be absolutely no doubt that the desert locust (which happens to be 99.99% of all locusts you'll ever see swarming in the region of Israel) is one of the kosher species mentioned in the Torah. 

But with birds... it's a whole different matter.

The Torah does not give signs via which to distinguish kosher from non-kosher birds. It just lists the names of the birds that are non-kosher. And this is a problem.

I've spent a quarter of a century working at identifying the creatures of the Torah. In some cases, one can reach 100% certainty, such as with the shafan being the hyrax. This is based on a convergence of evidence from many different areas - primarily identifying clues given in other locations in Tanach, but also comparative linguistics, evidence from other ancient sources, the ability to rule out alternate possibilities, and so on. But in other cases, one cannot be so sure. The yachmor is either the fallow deer or the hartebeest, but it's difficult to be certain which it is. Still, it makes no halachic difference, since with mammals we can rely on kosher signs.

But it's a problem with birds, since the Torah doesn't give any signs. It only gives names, and it's very difficult to know which birds are being referred to. I've served as consultant on this matter for ArtScroll and Koren and Chabad and Steinsaltz (the new Steinsaltz Chumash contains probably the best discussion of the matter), but while it's possible to achieve certainty or near-certainty for some of the birds, with others one cannot be anywhere near certain. We set up an exhibit of all the non-kosher birds in the Hall of Kosher Classification at the new Biblical Museum of Natural History, but as we explain to our visitors, we are far from certain as to the true identities of all the birds. The hoopoe is the popular and strongest candidate for the duchifat, but there is very little to go on. And as for birds such as the tachmos, there are many different suggestions, none of which are anything more than guesses.  

And there are all kinds of related difficulties. Since the nesher is undoubtedly the griffin vulture, where does the eagle appear on the list of non-kosher birds - is it the ayah, or is nesher a generic term that also includes eagles? Why is the ayit that descended on the carcasses of the Brit Bein HaBetarim not in the list of non-kosher birds - is it a synonym for another type, is it a generic name for scavenging birds, or is there some other explanation?

Even more problematically, the list of non-kosher birds in Re'ay is not the same as the list in Shemini! Now, the Gemara in Chullin addresses this, and argues that Moshe gave different names to some of the birds due to differences in what some people called them. But this just begs the question - if the Torah accommodated past name changes, what about future name changes?

The fact is that if you want to refer to an animal for an audience spanning different times and places, the absolute worst way to identify it is by its name. Because different places and different times have different animals. And consequently, names get transposed. 

The animal known today as a red deer in England is called an elk in America. But the word elk in England refers to the animal that Americans call a moose. 

Americans buy pet turtles. In England, a turtle is a sea-dwelling creature that reaches a yard in length; the reptiles that Americans buy are called tortoises (if they are terrestrial) or terrapins (if they live in lakes and rivers).

The American turkey vulture is also often called a buzzard. But in every other part of the world, "buzzard" refers to a very different bird of prey, of the Buteo family. Yet these birds are called hawks in America. Whereas "hawk" elsewhere refers strictly to birds in the Accipitridae family.

Now, the problem of identifying the birds of the Torah's list is not a new one. Consequently, the Tanna'im studied the kosher and non-kosher birds and identified a combination of characteristics which can be used to identify which birds can be eaten. (Unfortunately, it is very difficult to correlate this system with our knowledge of birds Still, most Rishonim are of the view that it can be implemented, though the stringent view that a tradition is required has recently become widely accepted.) But while previous generations grappled with the difficulty of identifying birds, they didn't discuss the inherent problem with the concept of the dietary laws being based on rules that would be destined to become incomprehensible.

Someone from the mystical school of thought might claim that the problem is just due to our limitations. The very first thing that man did in the world was to name the animals, and from the mystical perspective, this means that Adam was able to divine the fundamental nature of each animal and give it a perfectly appropriate name in the Holy Language which exactly expresses its essence. Accordingly, the Torah's listing of non-kosher birds is in fact a perfect way of describing them. But in fact, this is not much of a solution. None other than ArtScroll says that none other than some of Chazal themselves had difficulties identifying the birds. If identifying birds by means of kabbalistic powers is too much even for Chazal, then what chance does everyone else have?

All of this forces one to the conclusion that the Torah's way of identifying kosher from non-kosher birds is very limited in application. It cannot and could not possibly stand the movements of the Jewish People over the world and over history. And, if one believes that God authored the Torah, one must therefore also believe that God knew this. Yet He nevertheless gave a system that would prove impossible to implement after a few centuries.

So what is a believer supposed to do with that? Actually, it's not necessarily as a big a problem as it might first appear. But it might require some adjustment in one's conception of Torah.

Being an Orthodox Jew means accepting that the Torah is binding in all times and in all places. And yet, it has long been acknowledged (at least by the more rationalistically-inclined rabbinic authorities) that the presentation of Torah was oriented towards the generation that received it. (This is a topic that I discussed in detail in my book The Challenge Of Creation.) As Rambam puts it, "the Torah spoke in the language of man" - i.e. the people that first received the Torah. Rav Hirsch notes that the Torah's description of the "firmament" as a solid dome was in accordance with the conception of the universe held by people at that time. The same approach is necessary with numerous other scientifically-inaccurate statements in the Torah.

Rambam and others go even further than just saying that the Torah packaged its description of the universe in terms familiar to the generation that received it. They say that even certain commandments were primarily oriented to that generation. Naturally, this leads to a concern that later generations will abandon their observance, which is one reason why Rambam's advancement of this argument regarding offerings aroused much controversy. Still, he advanced it nonetheless, and there can be many other arguments for adhering to observing a commandment even if the primary original reason no longer applies.

And so the Torah's presentation of the laws of kosher birds is no different. For the generation that received the Torah, that was the most effective way of teaching them which birds may and may not be eaten. Yes, it's not a system that would withstand the later movements of the Jewish People through space and time. But then again, nor would all the laws which are dependent on living in the Promised Land!

It's also important to note that, in practice, the Torah's system for identifying kosher birds has not been problematic. Birds that were commonly available and farmed - chickens, ducks, and geese - were accepted without a problem. So were other commonly eaten birds, such as quail, guinea fowl, pheasants, and sparrows. Even turkey managed to get accepted before the Jewish community took on a more stringent approach to the dietary laws. For a variety of reasons too complicated to discuss here, it's safe to predict that there will never be any new species of bird to be commercially farmed.

It's true that recently things have taken a turn for the worse. Misunderstandings of both zoology and Talmudic natural history have lead many to believe that even some breeds of chicken may not be eaten. During the infamous Chicken Wars of 2017, it was claimed that all commercially available chickens are not kosher. Still, hopefully it will be possible to correct this error (my monograph on this topic is available in both English and Hebrew). I'm very much hoping that the Biblical Museum of Natural History, through its exhibits and publications, will successfully teach people that the laws of kashrus are both sensible and practical. The questions and difficulties are in the realm of fascinating theoretical and academic discussions - in practice, there is no shortage of birds to eat.

Nevertheless, as the global population increases, it will make more economic sense to obtain protein from insects. Food scientists have recognized this for years and are working to bring insects into the food market. Thank God, the Torah is future-proofed, and locusts are kosher!

The Biblical Museum of Natural History teaches tens (and soon hundreds) of thousands of people about the relationship between Judaism and the natural world. Please join our mission by becoming a Friend or Patron of the museum, and enjoy a personal tour of the museum, either in-person or via Zoom. See details at Thank you!

Guest Post: How People Get Sucked In

Dear Rabbi Slifkin, 

I wanted to reach out to you about your stance on Yaron Reuven. I wanted to share my experience with you with regard to Yaron Reuven, maybe it can add some insight into what you have been saying for some time. 

I picked up one of his CDs from a pizza shop about a year ago. I wasn’t looking for Kiruv or anything, I was born and raised a religious Jew and have learned for many years. I was just looking for something to listen to in the car on the way to shul and back that wasn’t music. I figured Torah was Torah and why not?

At first I didn’t see much wrong with what he was saying. His delivery was a bit different than what I am used to (many of my Rebbeim got Smicha from YU, so they are pretty different from someone like Yaron Reuven), which I didn’t think was a bad thing. He was a bit more Charif than most, but nothing too crazy (so I thought).

As I continued listening, I realized a trend in his “shuirim”. Most would start off mentioning a Mishnah in Perki Avos, then he would go on a tangent about some Rabbis or people (he wasn't specific about which Rabbi he was talking about) he thought were awful and were leading people astray. I didn’t think much of it, maybe he was right, how would I know, he wasn’t being specific. Over time I realized he went on these tangents a lot, like, a lot alot. Basically every “shuir” was bashing specific groups (like Chabad or Satmar) and saying how awful they are. For a shiur that is meant to be about bettering myself, I felt more like “well, at least I’m not as bad as these people.”

I then started realizing he was quoting Gemaras completely out of context and making conclusions based on his own assumptions, all the while calling it “the Torah” and saying stuff like “none of what I say is my own opinion, it’s all the Torah!” The irony of that statement is he is the most opinionated person I have ever listened to.

A specific example of misquoting a Gemera (which he did on multiple occasions) was the story of how Yashu went off the derech. Now, I am no fan of Yashu, I’m an orthodox Jew who davens with a minyan and learns daily, I am in no mean a Yashu fan, but the Gemara he quotes is entirely out of context. He uses the story in Sotah 47a to trash on Yashu. The problem with his explanation is that he completely ignores the context of the Gemara, which was discussing what Yashu’s Rabbi did wrong (the Gemara immediately before it discusses what Elisha did wrong and how he was pushed for it). Instead of teaching the lesson of “don't push away a student with both hands” he uses the story to trash Yashu. 

Him ignoring the message of the Gemara has practical ramification. Yaron himself pushes away people with both hands. Calls them Kofrim, Minim, etc, and way worse if they disagree with him. The exact Gemara he taught incorrectly is the Gemara he himself should be learning! No wonder he didn’t mention that part!  

He also has a very narrow understanding of the concept of “Tinok Shenishbah” which is a well debated concept and who falls into that category. He says it only applies to people who have never heard of Judaism before. I am not an expert in the area, but I have learned before that the definition is much broader than that. By narrowing it so much he causes people to view any non-religious Jew, who was born and raised non-religious as “someone who hates G-d” or vice versa. 

He also mentioned multiple times that someone who sleeps with a Nidah is doing something worse than sleeping with their own mother. Now, I have been through all of Shas and nowhere does it say that….. Sooooo, I don’t know where he gets that from, he doesn’t quote any source for it. I reached out on Facebook for clarification, but I haven’t heard back from him….. Doubt I ever will.

What really got my attention was a shiur (from a couple of years ago) where he started by mentioning that “the leadership of BRS (Boca Raton Synagogue) was making a horrible mistake by bringing a Christian missionary to speak there.” As someone who has been listening to Rabbi Efrem Goldberg for years, and who I have met personally, I was very confused about what he was talking about. I immediately googled it and found what had happened. Yaron was lying about what had happened and slandering the entire BRS community in the process. I may have known to look up what the truth was, but many aren’t going to do that. Especially after listening to one of Yaron's 4-hour “shiurim”. It was then I found your articles and realized how much worse the problem actually was and that I wasn’t the only one thinking “what wrong with this guy?”

His video about Rabbi Dweck (posted last week) where he bashes him for saying Dovid and Yehonatan were gay lovers (which I heard the audio of what Rabbi Dweck says, and its not true at all). I compared the audio Yaron played in his video to Rabbi Dweck's actual words and Yaron skips the part that Rabbi Dweck explicitly states Dovid and Yehonatan were NOT gay and that was the entire point of his shuir! I know Yaron did something similar with Rabbi Sacks shiur about the exodus. (I got into a debate with some of his followers on that video, they didn’t seem like they were going to listen to reason).

The point of my message is to explain my experience with listening to Yaron. It started with a refreshing new way of discussing Torah, which quickly became about people bashing and hatred. I can understand why people listen to him and believe everything he says. He’s very charismatic and entertaining, but, as you know all too well, also very dangerous. 

I hope you find my experiences and examples worth reading. I hope you can use them to help prevent further damage. 

Note from NS: Someone produced a powerful video which compiled some of the most damning of Yaron Reuven's statements. However, Reuven has managed to get it taken down from YouTube whenever it is posted. If someone knows how to host it online, or is willing to fight YouTube regarding it being fair use, please be in touch; I can send you the video. It can also be shared on WhatsApp.

Torah & Dogmatism

"Torah & Rationalism" (Feldheim 2020) is the title of a new book consisting of collected writings of Rabbi Dr. Aaron Chaim Zimmerman z"l, compiled by his student Michael Landy. Given its title, it naturally would seem to be of interested to readers of this forum, and several people have asked for my opinion of it. According to the book's blurb, "for the Torah Jew, this book will intellectually secure his mind by demonstrating the structure of Torah and Halachah in a rational way." I was given a copy to review and I was intrigued to read it.

Rav Zimmerman was renowned as an extraordinary prodigy, fluent in the entire Bavli, Yerushalmi, Rishonim and Acharonim, in the Brisker tradition. He served as Rosh Yeshivah at HTC in Chicago, as well as at other yeshivos in New York and Jerusalem. At the same time, he was a highly unusual rosh yeshiva. At one point during his illustrious career, he was clean-shaven, wore plaid shirts and drove a convertible! Great geniuses are often eccentric. Alas, in this case, the eccentricities carry forward into a deeply flawed work.

The book's various chapters discuss topics such as the nature of Torah She-ba'al Peh, Kabbalah, Rambam and Moreh Nevuchim, and "the falsity of academic Jewish scholarship." The fundamental problems in this book are ones that I have seen with certain other great geniuses and their devotees, notably Rav Moshe Shapira. Many people naively believe that if a great genius, and especially a great Talmudist, says something, then it must be true. But this is not the case. Genius has nothing to do with being correct; it just means that one is better able to devise arguments in support of rationalizing one's approach.

The first problem is the author's belief in an extreme (and very non-rationalist) interpretation of yeridat hadorot. He insists that as one goes back in the generations, people were actually more intelligent, and that as the generations continue to advance, people are intellectually regressing - not only with Jews, but also with non-Jews (pp. 27-28). One can only wonder what the world will look like in a few centuries - will our descendants be cavemen? But his claim that the genius of Aristotle's was never matched in a later generation, and nor that of Newton or Einstein, is simply wrong. After all, Einstein was as great a genius as Aristotle!

Following from this errant belief is the conviction that expounding extraordinary expositions on a text means that the text's author put those meanings into it, as opposed to the meaning being created by the reader. People such as R. Moshe Shapira and R. Zimmerman believe that the depth is being discovered, whereas in fact it is being created. Thus, R. Zimmerman claims that R. Chaim Brisker's intricate resolutions of contradictions in the Mishneh Torah bring to light Rambam's incredible genius. Whereas the fact is that there is nothing remotely resembling Reb Chaim's types of arguments in any of Rambam's writings (or, for that matter, in the writings of pretty much anyone preceding Reb Chaim.) Furthermore, when Rambam himself was asked about such contradictions, he didn't employ Brisker-style distinctions; instead he simply said that he erred, or changed his mind, etc. Finally, no less than the Chazon Ish states regarding some of R. Chaim Brisker's ingenious expositions that they are simply entirely baseless.

Another flaw which runs throughout R. Zimmerman's work is the religious conviction that no great Torah scholar was ever subject to any influence other than pure Torah. "It is impossible for them to define any aspect of Halachah according to public opinion, political outlook, social environment, or any other influence." Astonishingly, he even makes this claim about Rambam. R. Zimmerman states (pp. 98, 103. 110) that Rambam was not in the slightest way influenced by Greco-Islamic philosophy and that he gave it no significance whatsoever; instead, he merely incorporated such ideas in his work as parables to convey classical ideas from Sinai and the Sages in a form that would appeal to his readership. I could argue at length why this is utterly mistaken, but instead I will just point out that none other than the Vilna Gaon explicitly acknowledged that Rambam was influenced by Greco-Islamic philosophy in developing some of his views that were contrary to Chazal.

Yet another problem with R. Zimmerman's book, repeatedly illustrated, is the attitude that if a great Talmudist (such as himself) makes a very forceful claim, simultaneously disparaging those who disagree as being ignorant fools, then it carries great weight. This is something that crops up in the book again and again, to an almost unbelievable degree. On p. 25 he describes academic Judaic scholars as "lazy," "narrow-minded," with an "intent to disparage," and who only impress the "ignorant." Such statements carry on throughout the work, and vastly exceed any substantive arguments to back up these claims.

In general, the book is rife with extreme claims, forcefully stated, that are not only not backed up, but are actually contradicted by factual evidence. For example, on p. 94, as part of his efforts to dismiss Gershom Scholem as "a man absolutely ignorant in Torah, Halachah, Jewish thought, and philosophical understanding," he claims that kabbalists are wholly different from non-Jewish mystics, which is why "the whole genuine Torah world asserted immediately that Shabtai Tzvi was a charlatan." Alas, this is absolutely not the case - there were several renowned Torah scholars who were taken in by Shabtai Tzvi.

Its title notwithstanding, "Torah & Rationalism" is in fact a forceful polemic for the non-rationalist approach. Alas, I cannot recommend it.

The Unholy Trinity

After discussing the dangerous, hateful rantings of Rabbi Yosef Mizrachi and Rabbi Yaron Reuven, the topic should not be left without mentioning the third member of this unholy trinity: Rabbi Alon Anava. These three collaborate on various events and productions, and three-hour videos on YouTube. Like Mizrachi and Reuven, Anava has hundreds of hours of lectures, hundreds of thousands of followers on social media, and has distributed hundreds of thousands of CDs and DVDs. He's also on the faculty of a seminary for frum American girls in Tsefat.

Rabbi Alon Anava has some very interesting views.

He has a presentation on YouTube about the New World Order. In this video, Rabbi Anava explains that 9/11 was the work of a global conspiracy, led by the Rothschilds, the Clintons, and other puppet-masters. These secret groups have been functioning since time immemorial, using advanced technology - they built the pyramids to channel demons from the underworld. They are now trying to create a new World Order, which is also why they engineered the Covid pandemic (which makes people vulnerable to being zapped and incinerated by 5G). These figures secretly controlling the world are commonly known to be reptilians in human form, and that's because they are an incarnation of the Primeval Serpent.

Rabbi Anava also explains that the Vatican is connected to this Secret World Order, and they are more evil than you can possibly imagine. The Vatican is secretly a Devil-worshiping cult which sacrifices children. They even arrange with the Israeli Government (because they are also all puppets, controlled by the secret Cabal) to sacrifice children to the Devil in Israel.

Imagine that - a Jew spreading a blood libel against Christians!

I know. It sounds unbelievable that anyone could say such things, or that people would believe it. But you can watch it yourself on YouTube. (I didn't have patience to listen to more than a few minutes of his craziness - the video is three hours long!)

Now, you might be thinking, "Okay, Mizrachi and Reuven are crazy, but this guy is completely off-the-charts insane! How on earth would they associate with him?"

The answer is that Mizrachi and Reuven are also detached from reality. Mizrachi believes that stage magicians are actually performing real magic, and claims that Covid can be cured by firing a hot hair dryer down your throat! And Reuven believes that plants are intelligent, understand English, and get offended if we insult them!

It's a mistake to dismiss all this as harmless nonsense. Such anti-scientific, conspiratorial thinking leads to people acting dangerously with regard to pandemics and vaccinations. And when it's coupled to blood libels - whether it's Anava claiming that the Vatican conspires with Israel to sacrifice children, or Reuven claiming that the Jews really did destroy Germany with greed and perversion - there's no knowing what effects it can unleash. Not to mention Mizrachi and Reuven's endless talk about the violent deaths which heretical rabbis deserve. And these three rabbis have disciples who are even crazier than them - I received hate mail from one of them, who labels himself a "Radical Torah Supremacist," and posts YouTube videos about the evils of heretical Jews and Christians.

I don't believe that such dangerous nonsense should be tolerated.

How Can The Banned Ban?!

I'm hoping that this will be the last of my posts about the dangerous craziness of Rabbi Yosef Mizrachi and Rabbi Yaron Reuven. There is a loose end to tie up.

Several people have criticized my campaign against Mizrachi and Reuven as being hypocritical. Did I not complain when three of my books were banned? How can I then propose banning someone else?

Some people say that this is too ludicrous an objection to be even worth responding to. But since apparently not everyone realizes all the reasons why this is a flawed and nonsensical argument, I will spell it out.

First of all, I have never had any objection to people condemning and even banning books. On numerous occasions I have said that I don't like it when people automatically side with me merely because my works were banned - how do they know that my books weren't banned with good reason?! If I had truly written dangerous heresy, then the condemnation would have been wholly appropriate! And in fact I even repeatedly stated that to the extent that my books were thought to be dangerous to naive ultra-Orthodox Jews, I was fully sympathetic to efforts to block them from reaching such people!

It was the content of the condemnation which I disputed. I do not believe that it's remotely heretical to say that there was an age of dinosaurs and that there are scientifically incorrect statements in the Talmud. As it happens, I also don't have a problem with people who believe that the universe is only a few thousand years old and the Talmud is scientifically infallible, as long as they don't claim that it's forbidden to take the rationalist approach. I do have a problem with rabbis who say that it is a mitzvah to hate those who take this approach and that they are resha'im who deserve execution. This is entirely consistent with my advocacy of this approach - it's not hypocritical! Similarly, I have a problem with those who say that they would like to kill people who challenge their lectures. And who tell lies to enable antisemitism by broadcasting that Hitler was justified in hating the Jews because their immorality and greed destroyed Germany. 

Thus, to say, "How you can you want to ban someone when you complained about banned?!" is like saying "How can the IDF shoot terrorists when they complain about the terrorists shooting them?!"

In addition, there is a world of difference between a ban and a campaign of condemnation. Those who banned my books did not give reasons why they were heretical; instead, they tried to use their authority to declare that my books were forbidden. In such a case, I (and my mentors) felt that it was procedurally wrong, especially since I had obviously written these books with good intentions and under the guidance of widely respected rabbonim and to great positive impact, whereas the banning rabbis had been given a warped description of me, my books, and the effects of my books. With Reuven, on the other hand, I am not using authority to try to ban him - I don't have any! Nor am I relying on hearsay and agitation from kanno'im. Instead, I am presenting clear evidence as to why he is a menace to society and should not be given legitimacy.

Anyone who think that banning someone as a heretic for quoting Rambam is the same as urging the de-platforming of someone who urges hatred for "heretical" rabbis, declares them worthy of execution, and justifies Hitler's antisemitism, needs their head examining.

Finally, and perhaps most importantly: Some people have utilized this or a similar argument to tell me why they needn't do anything about Mizrachi and Reuven. "You're a hypocrite! You're just a bitter ex-charedi!"

But it's not about me! The campaign against Mizrachi and Reuven is based on what they said, not based on what I say. If some guy yells "Look out, there's a fire!" you don't ignore the fire just because you don't approve of the guy pointing it out!

Of course, given that there are people who are foolishly distracted by the messenger and ignore the message, it would indeed have been better had a more mainstream figure than myself been leading this campaign. Alas, nobody else stepped up to the plate. I've been getting a lot of encouragement behind the scenes from mainstream rabbinic figures, but they do not wish to publicly push the campaign themselves. This is a pity. But it doesn't change the fact that the case should stand on its own merits.

I've presented a lot of very clear video evidence of Rabbi Yosef Mizrachi and Rabbi Yaron Reuven inciting hatred against respected rabbis, speaking repeatedly about how they deserve execution, fomenting a Judaism consisting of violent apocalyptic fantasies, and insisting that Hitler was justified in saying that "the Jews are our misfortune." Anyone who tries to change the subject to talking about my supposed hypocrisy is not only mistaken; they are also responsible for enabling this dangerous madness.

When Rabbis Speak "Heresy"

What does one do when a rabbi says or does something deeply religiously problematic?

In numerous videos, Rabbis Yosef Mizrachi and Yaron Reuven have made their approach clear. People should be alerted to the problem. The guilty rabbis should be denounced as heretics and as wicked resha'im. It should be declared that it is a mitzvah to hate them. One must not learn anything at all from them. They should be declared deserving of execution.

I'm involved in a campaign to get Mizrachi and Reuven de-platformed for this (along with Reuven repeatedly publicly endorsing Hitler's reasons for hating Jews). Which includes, especially, Reuven no longer being declared "a rabbi in good standing" with the RAA (Igud HaRabonim). But, as one person connected with the RAA argued to me, rabbis declaring other rabbis to be heretical is hardly new. Is there really something novel about what Mizrachi and Reuven are doing?

The answer is yes, what Mizrachi and Reuven are doing is indeed novel. And wrong. And dangerous. And while for those who are seeking to be tolerant of diverse approaches, "novel and wrong" is not necessarily enough reason to de-platform them, "dangerous" is (or should) most certainly be adequate reason.

Historically, there have been numerous cases of rabbis saying things that others considered deeply religiously problematic. Traditionally, however, the Jewish and rabbinic community generally looked at the Big Picture. Exactly how religiously problematic and dangerous is the doctrine? What is the net effect of this rabbi on Judaism? Depending on the answers to these questions, the offending statements or actions might be overlooked. And even if, after this analysis, the offensive statements are worth condemning, this too is done proportionately.

With Mizrachi and Reuven, on other hand, they go to a crazy extreme. If they don't like a statement that a rabbi has made, or an action of his, they don't just consider it wrong - they rate it as absolute heresy. And they say that this negates everything else about the rabbi. And that it turns him into a wicked a person who must be hated and rated as a rasha to the extent that they are declared deserving of violent punishment and execution.

Rambam introduced vastly more radical theology than the rabbis on the "blacklist," for which there was a good deal of opposition - and yet Ramban (who was vehemently opposed to parts of Rambam's theology) successfully convinced others to let it go. And one of the most zealous crusades in Jewish history, that of Rav Yaakov Emden against Rav Yonasan Eybeshutz (where the central charge is likely correct!) is not held up as a model to be emulated. The accomplishments of these "heretics" and their general benefit to the Jewish people means that their problematic statements are either to be proportionately criticized, disregarded as non-threatening, or even overlooked.

Rabbi Ephraim Mirvis is the Chief Rabbi of the United Kingdom. This follows an immensely successful career as rabbi of several synagogues. He has created schools and community kollels and education programs that reached many thousands of people, along with the extraordinary "Shabbat UK" project.

Why do Mizrachi and Reuven condemn such an outstanding rabbinic leader as an evil heretic worthy of execution? Because he also said that while the Torah prohibits homosexuality, there should no bullying of LGBT+ people in Jewish schools, and worked with a pro-LGBT group to produce a guidance booklet for teens. Now, people might object to this and see it as a quasi-legitimization of Torah prohibitions. But when he explicitly states that these are nevertheless Torah prohibitions, is it really appropriate to denounce him as "a heretic, a hater of Torah, a cancer"?!

There's another justification that Reuven gives for his attacks on Rabbi Mirvis. In an interview about mental health, Rabbi Mirvis said that there should be no stigma about mental health challenges, and named several Biblical figures, such as King David, who suffered from them. Now, King David is revered as one of the greatest Jews in history. The normative approach of countless rabbinic authorities was to justify David's actions with Batsheva. Chazal explicitly stated that "anyone who thinks that King David sinned is making a mistake." And yet, Abarbanel says that David sinned grievously, with the crimes of murder and adultery!

Which is worse - having mental health challenges, or being an adulterer and murderer? Obviously, the latter. And yet, nobody declares Abarbanel to be a rasha and heretic whose every work must be destroyed. Why? Because, even for those who find his statements about King David to be deeply objectionable, the statements are not actual heresy. And they look at the Big Picture. Abarbanel is a respected authority who authored thousands of pages of commentary. You don't entirely negate him for a single problematic idea!

Rabbi Daniel Korobkin and Rabbi Efrem Goldberg are prominent rabbinic leaders of huge communities and are highly respected community rabbis. During their illustrious careers, Rabbi Korobkin had an interfaith dialogue session with an Imam, and Rabbi Goldberg invited a Christian motivational speaker. Sure, some might object to this. But according to Mizrachi and Reuven, it's not merely objectionable; it means that they are wicked heretics who deserve execution! And Rabbi Korobkin's session that was hosted and advertised by the RCA. Which according to Mizrachi and Reuven's logic, means that the RCA are also wicked heretics. It's endless!

Rabbi Lord Jonathan Sacks was Chief Rabbi of the United Kingdom for twenty years. He is the ambassador of the Jewish people to governments and leaders worldwide - and is astoundingly good at it. Anyone politically savvy knows how blessed our nation is to have such a gem. And the reach of his profound writings and lectures is incalculable. He is the author of over twenty bestselling works on Judaism, as well as translations of the siddur and machzorim.

Twenty years ago, one of his books included a radical claim that Judaism does not have a monopoly on spiritual truth. This was harshly opposed by certain rabbis, and Rabbi Sacks was summoned to a meeting with the Beis Din of my home town of Manchester. It so happens that this idea has more support in traditional Judaism than is commonly assumed, though Rabbi Sacks went far beyond any previous formulation. And Rabbi Sacks rewrote the offending passages in the subsequent edition. No other Orthodox rabbi in the world (with the exception of the Mexican lunatic Isaac Betech) sees fit to maintain a campaign against Rabbi Sacks, one of the most prestigious and impactful rabbis in the world, due to a few retracted paragraphs written twenty years ago. But for Mizrachi and Reuven, this minor aspect of his career is enough to repeatedly mock him and denounce him as an evil heretic who deserves to be stoned to death!

Another crime of both Rabbi Sacks and myself was to argue for a non-literal approach to Creation. But even the most zealous of the charedi Gedolim who condemned my work didn't come close to making the kind of statements about me that Mizrachi and Reuven make! Reuven seeks to justify his tirade against me by invoking Rav Elyashiv; but Rav Elyashiv didn't engage in the kind of speech that Reuven does! And with good reason - they knew that (A) these approaches were presented by distinguished rabbinic authorities in our history, and (B) at the end of the day, such approaches are not actual heresy, and certainly don't render their advocates as worthy of the death penalty!

And while the "crimes" of Rabbi Sacks and Rabbi Mirvis and Rabbi Korobkin and Rabbi Goldberg are a tiny aspect of their work, the crusading against such "heresy" isn't a small aspect of the Mizrachi/ Reuven approach. It's something that they push again and again and again as a fundamental religious duty. And just as these two are recent returnees of Judaism, with no real scholarly credentials, but claiming legitimacy as crusaders against evil, likewise they inspire other ignorant people to attain Jewish value by denouncing and hating others.

Still, even after all this, a person could argue that Mizrachi and Reuven should not be de-platformed. If we are saying that people should be tolerant of opinions to which they strongly object, then shouldn't we likewise be tolerant of Mizrachi and Reuven?

The answer to that is that Mizrachi and Reuven are not merely objectionable. They pose a clear and present danger to the community.

In the Mizrachi/Reuven approach, someone whom they have rated as a heretic is not merely declared to be treife; they speak about how the people must be actively hated and are liable for the death penalty. Mizrachi says that he would like to throw them head-first through a window. And anyone who defends and/or associates with these "heretics" is likewise to be hated and declared equally evil and worthy of violence and execution.

We've seen where this leads in Israel, where the overly heated rhetoric in the Ponovehz yeshivah led to pipe bombs and riots in the yeshivah, and the Rav Shmuel Auerbach feud led to an unstable individual breaking into an elderly rabbi's home and beating him up. And those incidents were due to an isolated area of disagreement; Mizrachi and Reuven are creating a whole religion based on hatred. Reuven's Tisha B'Av video, titled "Stop Hating Each Other," was mostly about why the 14 rabbis on Mizrachi's blacklist are reshaim that people have to hate!

Reuven is Mizrachi's protege, and takes his mentor's craziness even further. What's the next level of craziness going to be? It's not like the zealous rabbis of history, who were teaching their own small group of disciples. Mizrachi and Reuven share their incitement on YouTube and Facebook, reaching hundreds of thousands of people of all types, including the most unstable individuals. Mizrachi has already described, on more than one occasion, how certain followers of his would like to commit violence against those that he has targeted. Are we just waiting for it to happen? And then will we claim that we couldn't have seen it coming, that we couldn't have done anything about it?

The zealotry and violent rhetoric of Mizrachi and Reuven is not merely "just more rabbis squabbling." It's a dangerous usage of modern technology to spread a new approach to Judaism of mass-scale violent fantasies, delegitimization and incitement to violence. It must be stopped.
