Sun. 6/26 at 11am: Crypto-Judaism is the secret adherence to Judaism while publicly professing to be of another faith; practitioners are referred to as "crypto-Jews." The term crypto-Jew is also used to describe descendents who maintain some Jewish traditions of their ancestors, often secretly, while publicly adhering to other faiths, most commonly, Catholicism.

The phenomenon arose in the middle Ages following the expulsion of the Jews in 1492 from Spain. Guests are an expert in the study and research of crypto-Judaism and a man who is now a practicing Jew after having discovered his Jewish roots.
