The circumcision controversy in early Christianity played an important role in Christian theology.
The circumcision of Jesus is celebrated as a feast day in the liturgical calendar of many Christian denominations, while the teachings of the Apostle Paul asserted that physical circumcision was unnecessary for the salvation of Gentiles and their membership in the New Covenant. The first Council of Jerusalem (c. 50) declared that circumcision was not necessary for new Gentile converts (as recorded in Acts 15); Pauline Christianity was instrumental in the split of early Christianity and Judaism and eventually became Christians' predominant position. Covenant theology largely views the Christian sacrament of baptism as fulfilling the Jewish practice of circumcision, as both serve as signs and seals of the covenant of grace.
