Feast of the Circumcision of our Lord Jesus Christ on the eighth day after His Nativity.
On the eighth day after His birth the Lord Jesus Christ was circumcised according to the Law of Moses and received the name Jesus, as the angel had announced to the Virgin Mary. The Church keeps this feast of the Lord on January 1, together with the memory of St. Basil the Great.
The feast shows Christ's humility in submitting to the Law He Himself had given, and is understood by the Fathers as a foreshadowing of Holy Baptism, the circumcision made without hands.
