  • Please Join Me in Spain and Portugal

    Please Join Me in Spain and Portugal

    I’m really thrilled to be cruising the Douro River this summer with Kosher Riverboat Cruises, lecturing on the history of Spanish and Portuguese Jewry (my wife plans to come along, which means I really have to bring my A-game). I just learned that there’s only 18 cabins left, so if you’re interested, please click the……

  • “Should We Tear Down Statues of Khmel’nyts’kyi and Petliura?”

    “Should We Tear Down Statues of Khmel’nyts’kyi and Petliura?”

    Conference presentation at the “The 100th Anniversary of the Ukrainian Revolution and the Proclamation of Ukraine’s Independence,” held at the Ukrainian Institute, New York, Sunday, January 21.  My talk was inspired by a thought-provoking article in the Forward by Avital Chizik-Goldschmidt. A fascinating panel, which included Anna Procyk of CUNY, Serhy Yekelchyk of University of……

  • The Aish Kodesh On Beshalah (January 20, 1940 in the Warsaw Ghetto)

    The Aish Kodesh On Beshalah (January 20, 1940 in the Warsaw Ghetto)

    On Parashat Beshalah (January 20, 1940), a young rebel escaped from the notorious Pawiak Prison, located not far from the Piaseczno Bet Midrash. Andrzej Kott, the 21-year old leader of the military wing of a resistance movement called the Polish People’s Independence Action, was a child of assimilated Jewish parents who had converted to Christianity….…

  • The Aish Kodesh and Rav Shagar (Parashat Bo 5702, January 24, 1942)

    The Aish Kodesh and Rav Shagar (Parashat Bo 5702, January 24, 1942)

    The recent translation of the work of Rabbi Shimon Gershon Rosenberg (Rav Shagar, 1949-2007) promises to elevate his distinctive thought to a broader audience of readers (Faith Shattered and Restored: Judaism in the Postmodern Age), many of whom will resonate with Dr. Yitzchak Mandelbaum’s comment on his discovery of Rav Shagar: “I knew I had……

  • The Deleted Drasha: Aish Kodesh on Parashat Bo 5700 (January 13, 1940)

    The Deleted Drasha: Aish Kodesh on Parashat Bo 5700 (January 13, 1940)

    The Rebbe’s entry for Parashat Bo (January 13, 1940) is unusual. Recorded in the scribe’s careful hand, with minimal annotation, it has two bold diagonal lines drawn through the center of the text, indicating that the Rebbe rejected it altogether. A brief and uncharacteristic first-person comment is appended: “more of what we said I do……

  • Working on Spanish Edition of Kabbalah of Forgiveness!

    Working on Spanish Edition of Kabbalah of Forgiveness!

    Really nice to meet with Jésica Neuah of Editorial Perspectivas to work on the tentative cover and book design of the Spanish edition of The Kabbalah of Forgiveness! Great to work with her and the whole team. G-d willing the book will be released in the summer of this year.

  • Rabbi Shlomo Katz on the Aish Kodesh

    Rabbi Shlomo Katz on the Aish Kodesh

    I had chills listening to Rabbi Shlomo Katz review the Rebbe’s words on this week’s parashah. I am grateful for his kind words of praise for my recent book on the historical context of the Aish Kodesh, but to tell the truth, I hardly recognized my own words from the masterful treatment they received from……

  • The Aish Kodesh On Vaera 5702 (January 1942 in the Warsaw Ghetto)

    The Aish Kodesh On Vaera 5702 (January 1942 in the Warsaw Ghetto)

    Chaim Kaplan recorded the mood in the Warsaw Ghetto in January 1942:  The cold is so intense that my fingers are often too numb to hold a pen. There is no coal for heating and electricity is sporadic or nonexistent. In the oppressive dark and unbearable cold your mind stops functioning. Yet even in such……

  • The Aish Kodesh on Vaera 5700 (Torah from the Warsaw Ghetto, January 1940)

    The Aish Kodesh on Vaera 5700 (Torah from the Warsaw Ghetto, January 1940)

    Five months into the Nazi occupation, the Jews of Warsaw struggled to keep up with the barrage of administrative decrees inflicted upon them by the Germans. When the Rebbe spoke on Parashat Vaera, which fell on January 6, 1940, the worst was still far off. The Nazis had replaced the leadership of the Jewish Council……

  • The Aish Kodesh on Shemot 5702

    The Aish Kodesh on Shemot 5702

    The winter of 5702 brutalized the Jews of the Warsaw ghetto with unforgiving cold. Chaim Kaplan, a school principal whose journal Scroll of Agony survived the war, recounts in his typically blunt prose how the physical privations of January 1942 affected the spiritual life of Ghetto inhabitants: Gone is the spirit of Jewish brotherhood. The……

  • The Piaseczno Rebbe on Vayigash

    The Piaseczno Rebbe on Vayigash

    On December 27, 1941, the Piaseczno Rebbe delivered his last recorded drashah on Parashat Vayigash in the Warsaw Ghetto. The previous month was especially brutal: an especially cold winter, combined with a severe coal shortage, exacerbated the typhus epidemic, and each morning a detail of the chevra kadisha patrolled the streets to collect the bodies……

  • The Dreyfus Affair (This Week in Jewish History)

    The Dreyfus Affair (This Week in Jewish History)

    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……

  • Who Was Josephus?

    Who Was Josephus?

    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……

    Photo: Aryeh Abramson looks out over Iroquois Falls, Ontario, Canada, where he spent the Sukkot vacation visiting his grandparents. 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……

  • Free Download of Maimonides on Teshuvah by Dr. Henry Abramson

    Free Download of Maimonides on Teshuvah by Dr. Henry Abramson

    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 and the Jews (This Week in Jewish History) Dr. Henry Abramson

    Pope Gregory I and the Jews (This Week in Jewish History) Dr. Henry Abramson

    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.

  • Jewish Children Forced Into the Tsar’s Army (This Week in Jewish History)

    Jewish Children Forced Into the Tsar’s Army (This Week in Jewish History)

    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.

    Judaism and the Origins of Christianity HIS 155 Lecture 1.4

    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……

  • Jews, Lepers and the Black Death (This Week in Jewish History)

    Jews, Lepers and the Black Death (This Week in Jewish History)

    The summer of 1321 was plagued with rumors that Jews had entered into a conspiracy with lepers (some versions also included Muslims) to poison the wells of Europe, resulting in mass hysteria and mob violence. King Philip V was eventually able to quell the movement, but it resurfaced twenty years later in a much more……

  • Nathan the Wise by Gotthold Ephraim Lessing (This Week in Jewish History)

    Nathan the Wise by Gotthold Ephraim Lessing (This Week in Jewish History)

    In August of 1778, the non-Jewish writer Gotthold Ephraim Lessing wrote to his brother of a new literary project designed to further tolerance of Jews in German society. The result was Nathan the Wise, a sensation that was initially banned by the Church and heavily criticized by antisemites of the day.
