Rabbi Zalman Weiss is an Orthodox rabbi living Jerusalem, Israel. He received smicha from Rabbi Zalman Nechemiah Goldberg, and studied at the yeshivas of Kol Yaakov in Munsey, NY, and Ohr Samaych and MiLi in Jerusalem, Israel. Rabbi Weiss has been actively involved in the education of potential converts for many years, working with the Beis Din of Rabbi Nissim Karelitz of Bnei Brak. His students probing questions about faith in G-d and the tenants of Orthodox Judaism inspired the research that evolved in this book.
