From Shimon Apisdorf’s “Rosh Hashanah Yom Kippur Survival Kit” Leviathan Press 2000, p.60:
An Israeli newspaper reported that tens of thousands of recent Russian immigrants, children and adults, have received a bris mila (circumcision) upon their arrival in Israel. Many of these take place in almost assembly line fashion with the mohel performing one after another. A newspaper reporter was questioning the immigrants waiting in line about the motivation for their actions. When asked if he believed in God, one middle-aged Russian who was raised on a steady diet of communist propaganda declared, “No, I don’t believe in God, I’m an atheist.” The curious reporter, a bit taken aback, went on, “Then why are you having a bris?” There in the land of Israel, the land of King David and the Maccabees, of the Western Wall and Ethiopian Jews, the Russian answered proudly, “Without a bris, it is impossible to be a Jew!”
