Aish Kodesh scholar Daniel Reiser holding a copy of my new book. Like Shakespeare holding a copy of one’s sonnets. Thank you!

The Piaseczno Rebbe, Rabbi Kalonymus Kalmish Shapira, refused to dignify the Nazis by naming them in his wartime sermons in the Warsaw Ghetto. In a rare moment of transparency, perhaps motivated by anguish over the suffering of his Hasidim, the Rebbe briefly suspended his euphemistic terminology with a curt third-person reference in his drashah on Parashat…

I was stopped on my way in to davening this morning by someone who told me about the incredible shiur that Rabbi Efrem Goldberg of Boca Raton Synagogue gave on the Aish Kodesh this week. Here’s the excerpt–Rabbi Goldberg captures the agony of the Rebbe after the loss of his family in his typically powerful…

Please click here to read the review at The Jewish Star. By Alan Jay Gerber The name and history of the Aish Kodesh in our community is well known. This legacy from the tragedy of the Warsaw Ghetto of one of its towering leaders, Rebbi Kalonymus Kalmish Shapira, the Aish Kodesh, has been taught to us…

I was deeply moved by the kind support of my research into the life of the Aish Kodesh at the book launch this week. By all accounts, it was a wonderful evening–we had such a diverse crowd in attendance, from pious Hasidim well familiar with the Piaseczno Rebbe to students who knew nothing about his…

Thanks to Rabbi Pesach Sommer for recording my brief comments at the conclusion of the hilula (74th anniversary of his martyrdom) for Rabbi Kalonymus Kalmish Shapira at The Shtiebl in Williamsburg, NY. SHOW MORE

Very grateful to Rabbi Pesach Sommer for writing a kind and generous review of Torah from the Years of Wrath! My favorite passage is at the end: “Dr. Abramson has written a book which is destined to lead to an increase of study of the rebbe’s Torah and thought in both the academic and Jewish…


Compiled by Rabbi Yehuda Ha-Nasi in an exceptionally difficult time for the Jewish people, the Mishnah created the possibility of creating a “portable Judaism.” After the destruction of the Temple in 70 and the dramatic escalation of the diaspora, the Mishnah allowed Jews to define their religion within an intellectual and textual context, outside of…

Virtually ignored by Jewish philosophers, Philo of Alexandria represented the high point of synthesis between Greek and Jewish thought in the ancient world, and had a huge influence on early Christian thinkers. A prominent representative of the Egyptian Jewish community to the Roman Emperor, and well-respected in his day by his coreligionists, he nevertheless had…

Wrongly accused of espionage, Captain Alfred Dreyfus was sentenced to Devil’s Island on the basis of remarkably tenuous evidence. May critics, including the famous writer Emile Zola, argued that Dreyfus was unfairly charged simply because he was a Jew in the French army. As evidence mounted that another officer was guilty, the Dreyfus Affair exposed…

Captured by the Romans, Josephus was a Jewish general who ultimately served as a military advisor to General Titus. Josephus recorded his first-hand observations of the destruction of the Temple, and went on to a brilliant literary career in Rome, describing Jews and Judaism to a wider audience. Who was Josephus–traitor to his people or…

Rembrandt is well-known for his depictions of Jewish subjects, both as contemporary portraits and as models for Christian biblical characters.

Captured by the Roman General (and later Emperor) Vespasian while defending the Galilee, Josephus ultimately turned against his coreligionists and served as an advisor to the forces besieging Jerusalem during the first Roman-Jewish War. His first-hand…

Moses Maimonides (1135-1204) was one of the greatest minds the Jewish people ever produced: philosopher, jurist, physician, and an extremely prolific writer who left us classics like The Guide for the Perplexed and the Mishneh Torah. For several years I have been in the habit of reviewing his Laws of Repentance in the weeks leading up to the…

Pope Gregory I (“the Great”) was one of the most influential Church leaders of the medieval period. His policy on the treatment of Jews in Christian Europe, known by the Latin phrase “Sicut Judaeis,” instituted an official if ambivalent position that lasted from the sixth century to the beginnings of the modern era.

Reeling from the humiliating defeat of the Crimean War, the Russian Empire decides its policy of forcibly conscripting Jewish boys into military service is counterproductive, and finally abandons the cruel decades-old policy of taking underage children into thirty-one years of military training and service.

The Roman-Jewish Wars Our sources for the Roman-Jewish wars of the first and second centuries are more substantial than those of earlier periods, primarily because the importance of developments in this tiny…

Born in turbulent times, Christianity emerged from its intensely Jewish roots to become the official religion of the Roman Empire within a remarkably brief period of time. As a daughter religion to Judaism, however, dissent between the two faiths slowly dominated the discourse as Christianity became less of a Jewish movement, and more of a…
