Halachah, Medicine, And The Pandemic

By Rabbi Aryeh Klapper

For those focused on contemporary issues, Rabbi Mordechai Willig’s “Confronting the Pandemic in the Community: A Rabbi’s Memoir” offers unprecedented insight into the way halachic decisions were made for our community during COVID.

‘Rupture And Reconstruction’ Reconstructed

By Rabbi Aryeh Klapper

Rupture was intended as a description of the development of Ashkenazic, mitnagdic post-migration Orthodoxy. It was never actually about 1990s American Modern Orthodoxy and its anxieties, or about how to resolve them.

A New Look At The Life Of Rabbi Eliezer ben Hyrcanus

By Rabbi Aryeh Klapper

Dr. Sokol presents Rabbi Yochanan’s refusal to make the first move toward reconciliation as a “heroic choice” to “valorize respect for Torah’s masters over his own search of Torah truth.”

By Rabbi Aryeh Klapper

Parsha

Shakespeare's Korach--and Chazal's

By Rabbi Aryeh Klapper

Seems men are puppets and women pull the strings.

Redeeming Relevance / Rabbi Francis Nataf

Redeeming Relevance: Parshat Bhaalotekha

By Rabbi Aryeh Klapper

Constitutional democracy is a better form of spiritual government than either anarchy or totalitarianism. G-d wanted intellectual diversity and as close to universal accountability as possible.

Parsha

Sefer Bamidbar: How to be Tzanua, Like G-d

By Rabbi Aryeh Klapper

Considering tzanua and achieving a balanced version of it in order to walk with G-d

Parsha

Reclaiming Relevance

By Rabbi Aryeh Klapper

Some argue that when a Talmudic rabbi declares that a law “never was and never will be”, he is actually signaling a moral shift in which a Torah law is quietly put out to pasture. I am not convinced by this argument.

Parsha

Matrilineal Lives Matter

By Rabbi Aryeh Klapper

“Remove the blasphemer to outside the camp.  All those who heard will rest their hands on his head.  The entire congregation will pelt him.” I suggest that the blasphemer was not executed. Rather, he was taken to the scaffold and pelted with a single rock. 

Parsha

Are Tzaddikim Necessarily Role Models?

By Rabbi Aryeh Klapper

A healthy religious society has room for both chakhamim and chasidim, but knows that the latter are generally more to be admired than imitated.

Parsha

Are Sacrifices Essential to Judaism? 

By Rabbi Aryeh Klapper

Why is the act of sacrifice so powerful psychologically?  Why do human beings naturally express themselves religiously through sacrifice, whether they are expressing fear or gratitude?

Parsha

Is Halakhic Sophistication Always a Virtue?

By Rabbi Aryeh Klapper

Torah thoughts on this week's parsha, Vayakhel-Pekudei

Parsha

SOME KIND OF BLUE? TEKHELET and TRADITION

By Rabbi Aryeh Klapper

One can claim with regard to specific halakhic issues that a tradition is binding even though it is not intellectually or spiritually compelling.

Parsha

Does Judaism Recognize the Notion of Systemic Injustice?

By Rabbi Aryeh Klapper

The path from moral principle to moral policy is rarely straightforward. But the path from lack of moral principle to immoral policy often is straightforward.  

Parsha

Reframing the Debate Over Women's Religious Leadership

By Rabbi Aryeh Klapper

The religious state of nature does not enable the building of a religious society. Since human beings are social creatures, it follows that the state of nature does not enable human fulfillment.   We therefore need a religious social contract.  Cue Sinai; enter, the Torah.

Parsha

IF A FROG JUMPED INTO A FIERY FURNACE, WOULD YOU JUMP TOO?

By Rabbi Aryeh Klapper

How seriously should we take frogs as halakhic authorities? On one level the answer is clear: not at all. Frogs do not have free will, or moral responsibility, and anyone one who thinks this midrash believes otherwise defames Chazal.  Froggish martyrdom cannot teach us proper Jewish behavior, any more than froggish diet can teach us that insects are kosher.

Parsha

FATE, DESTINY, AND FREE WILL

By Rabbi Aryeh Klapper

Imagine that the book of your life has already been written – and that you’ve read the chapter headings. How would your life be different? This issue is addressed by J.K. Rowling in the Harry Potter series. Not surprisingly, Rowling was preceded by the Torah

Parsha

A Pre-Modern Joke about Post-Modernism

By Rabbi Aryeh Klapper

Human interpretation of G-d’s work is always reaching beyond ourselves, and we should be suspicious of any theory that successfully explains everything in Torah – more likely we are imposing our own vision on the text.

Parsha

What our Negotiators can Learn from Yitzchak

By Rabbi Aryeh Klapper

It is unwise to see contemporary events as exact replays of Biblical history, but it is valuable to recognize that Torah and tradition offer narratives of hop--as well as gloom--about Jewish national relationships

Parsha

Lot as an Orthodox Mirror

By Rabbi Aryeh Klapper

Religion must face the question of how its followers should behave while members of a corrupt society.  How should they relate to the norms of that society, especially when those norms are embodied in law?  

Parsha

Noach and Global Warming

By Rabbi Aryeh Klapper

But the question of Noach and global warming can be understood as a theological rather than a factual question: Are there any circumstances under which G-d would allow the human race to be destroyed?

Parsha

Saying the Unsayable: Does Reciting the 13 Middot ALWAYS “Work”?

By Rabbi Aryeh Klapper

What is the difference between religion and magic?  Each makes the claim that events in the physical world can flow from metaphysically effective language.  Mages recite spells; sages recite prayers.  So why is it that the Torah bans magic yet mandates prayer? 

Parsha

Two Cheers for Paternalism

By Rabbi Aryeh Klapper

Rabbi Aryeh Klapper on parshat Nitzavim-Vayelech

Parsha

On Washing Dirty Linen in Public

By Rabbi Aryeh Klapper

There is a natural temptation to explain away the nasty and intemperate statements of the side we identify with, while setting upon the other side’s gaffes with ferocity.   But in the end this asymmetry undermines our reputation for justice, and thus our capacity to persuade rather than overpower. 

Parsha

Day School Tuition and the Pierced Slave

By Rabbi Aryeh Klapper

A society that structures its economic institutions to make all genuine partners fulfills the mitzvah of tzedakah. A society that institutionalizes dependence, no matter how reliably it provides for its dependents, has turned them into pierced slaves

Parsha

The Philosophy Behind a Verse

By Rabbi Aryeh Klapper

The questions have thus led us to at least two major hashkafic issues: the status of Jewish life outside Israel, and the connection between virtue and success in this world. 

Parsha

Why Rabbis and their Communities Must Learn from Each Other

By Rabbi Aryeh Klapper

This week’s parshah, Matot-Masei- provides a powerful lens from the past to train on current events. 

Parsha

A Light to the Nations?

By Rabbi Aryeh Klapper

Why did G-d use Bilaam to bless the Jews, if by doing so He enabled Bilaam to learn how best to attack us?

Parsha

Parshat Korach: How Should Jewish Leaders Handle Challenges to their Authority?

By Rabbi Aryeh Klapper

Korach assembles the people against Moshe - but did they actually engage in, or threaten to engage in, disobedience?  The text as we have it records NO active illegality.

Parsha

Moshe Rabbeinu's Other Wife: A Case of Midrash and Masoret

By Rabbi Aryeh Klapper

Did Moshe go to Ethiopia as an accepted Egyptian prince, or as part of his escape after killing the Egyptian? Was his marriage a genuine and consummated relationship, or a purely political alliance?

Parsha

Parshat Bamidbar

By Rabbi Aryeh Klapper

Humility, as embodied by Hilel, should be among our community’s priorities as we develop the educational policies and personnel that will shape the next generation of halakhic leadership.

Parsha

Are Our Bodies Metaphors for Our Souls?

By Rabbi Aryeh Klapper

Granting that bodies and souls are sometimes mismatched, are we comfortable saying in absolute terms that sheker hachein v’hevel hayofi (grace is falsehood and beauty is meaningless)? Are bodies and souls assigned to one another at random?

Parsha

The Integrated Religious Life

By Rabbi Aryeh Klapper

. . Few texts seem less philosophically promising at first glance than a pasuk in this week's parsha “anything that a zav lies on becomes tamei” (Vayikra 15:4)

Op-Eds

Instinctive Liberalism And Halachic Conservatism

By Rabbi Aryeh Klapper

Orthodoxy should celebrate the instinctive liberalism of non-Orthodox Jews as a profound religious fulfillment of their human and Jewish nature without endorsing the policies of American liberalism
