However important it may be in Judaism, circumcision is not a sacrament, unlike a Christian baptism. Circumcision does not affect a Jew's Jewish status; a Jew by birth is a full Jew, even if not circumcised. Even so, the punishment for not being circumcised in rabbinic Judaism is believed to be "kareth", "being cut off"; meaning premature death at the hand of G-d (Mo'ed Katan 28a) and a severe spiritual punishment, the "soul's being cut off," and not being granted a share in the world to come (Hilchot Teshuvah 8:1,5).
