Thirteen years after discovering his Jewish roots, 64-year-old Moshe Lederman Cohen celebrated his bar mitzvah at Jerusalem’s Western Wall. Born Mariusz Robert Aoflko in Poland, his mother told him he was Jewish just before she died. Israeli organization Shavei Israel brought him to Israel. Moshe said, “This is the most important day in my life. I feel like I’ve come home”.
