On the eighth day after His birth, Jesus Christ underwent circumcision, as prescribed by the Old Testament Law. This practice symbolized God's Covenant with Abraham and his descendants. The circumcision was followed by the naming of the Divine Infant as Jesus, as the Archangel Gabriel had announced during the Annunciation to the Virgin Mary. The purpose of Jesus' circumcision was to set an example of faithfully fulfilling divine ordinances and to affirm His true assumption of human flesh. This act also dispelled any doubts about the reality of His Incarnation. In the New Testament, circumcision was replaced by the sacrament of Baptism, which it foreshadowed. The Feast of the Circumcision of the Lord was celebrated in the Eastern Church since the fourth century. It is a reminder to Christians of their entrance into a New Covenant with God, signified by their spiritual circumcision and the adoption of the name "Christian.
