For more than 40 years, “On Faith” panelist Rabbi Adin Steinsaltz has devoted himself to the monumental undertaking of translating and reinterpreting the Talmud, the vast collection of rabbinic writings that constitute Jewish civil and religious laws. Steinsaltz, who lives in Jerusalem, began this task in 1965, when he founded The Israel Institute for Talmudic Publications. The Steinsaltz Edition of the Talmud, of which 37 volumes have been published so far, has made the Talmud accessible to tens of thousands of Hebrew speakers. In 1989, he began producing an English edition of 22 volumes. Since 1994, 15 volumes have been published in French, and four have appeared in Russian. The Talmud project has been described as the most important Jewish publication endeavor of the 20 th Century. Steinsaltz has written some 60 books and hundreds of articles on a wide variety of topics, including Hasidism and the Jewish mystical tradition of Kabbalah. One of his most popular books is The Thirteen Petalled Rose , which he describes as “a little book for the soul.” In 1989, Steinsaltz established a Russian branch of Mekor Chaim--the first Jewish institution to receive official recognition in the former Soviet Union . He also founded the Aleph Society, and the Mekor Chaim Educational Institutions. In 1988, Steinsaltz received the prestigious Israel Prize--his nation's highest honor. He has lectured at major universities and research institutions in the United States and Europe, including Princeton University , Yale University , Columbia University , the Woodrow Wilson Center , Oxford University and the Sorbonne.

He also earned a doctorate in moral theology at the Pontifical University of the Holy Cross in Rome. Monsignor Bohlin was ordained a priest for the Prelature of Opus Dei in 1997. Prior to coming to New York as the head of Opus Dei in the United States, he worked for the five years with Opus Dei’s Prelate, Bishop Javier Echevarría, at Opus Dei's international headquarters in Rome as chancellor for Opus Dei. Monsignor Bohlin has spoken about faith issues on such news programs as “Hardball with Chris Matthews” and “Meet the Press.” Opus Dei has 87,000 members worldwide and 3,000 in the United States. Pope John Paul II canonized Opus Dei’s founder, Saint Josemaría Escrivá, in 2002, calling him “the saint of ordinary life."
