The basis for Jews to circumcise their sons is found in the bible (Genesis 17, 10-14), where it says: "This is my covenant, which ye shall keep, between me and you and thy seed after thee; every man child among you shall be circumcised".
The circumcision of newborn Jewish boys belongs to the essence of Judaism, it marks the entry into the Jewish community and symbolises the ties between God and Abraham and between God and the Jews. The command is compulsory for Jews.
Circumcision is also practised by secular Jews and connects Jews of all tendencies, from orthodox to reform, with another. It is not only a tradition but a central part of the Jewish identity. It is of essential significance and constitutive for being a Jew.
Circumcision counts as one of the most important commandments in Judaism and even outweighs the commandments of the highest Jewish feast days, Shabbat and Yom Kippur (Day of Atonement), on which certain activities may not be carried out.
Even during the Nazi era, when circumcision was a sign of belonging to Judaism and could be a death sentence, Jewish boys were still circumcised: it was even carried out in Nazi labour camps. To abolish circumcision in Judaism is not under any circumstances conceivable.
