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…

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.
