The source for brit milah is the biblical commandment for Avraham to circumcise himself, all the males of his household, and all his male descendants: This is my covenant, which you shall keep, between me and you and they seed after thee; Every manchild among you shall be circumcised. And you shall circumcise the flesh of youf foreskin; and it shall be a token of the covenant between me and you. And he that is eight days old shall be circumcised among you. (Genesis 17:10) In fact, the Torah recounts several other cases of brit milah: Avraham's own circumcision, Tzipora, Moshe’s wife, circumcising their son, and Joshua's circumcision of all the previously uncircumcised males before the Israelites entered the Land of Israel. The Jewish people continued to observe brit milah through the generations and circumcision has become the most profound symbol of the Jewish community, a physical sign attesting to a covenant of the heart. Jews throughout history risked their lives to circumcise their children as the brit milah was a symbol of Jewish distinctiveness. Circumcision does not determine the Jewishness of a child: having a brit milah does not make a non-Jewish child Jewish just as not having a brit milah does not make a Jewish child non-Jewish. Still, this act represents a transitional moment as the newborn now carries a testimony to his inclusion within the Jewish people. Though some pain necessarily accompanies this act, brit milah is the way man becomes God's partner in tikkun olam, the perfecting the world. Therefore, the brit milah of a newborn has always been celebrated and followed by a festive meal - celebrating his connection to the Jewish community.
