The Lutheran Church and the Greek Orthodox Church celebrate the Circumcision of Christ on 1 January, while Orthodox churches following the Julian calendar celebrate it on 14 January. All Orthodox churches consider it a "Great Feast". In much of Western Christianity, the Feast of the Circumcision of Christ has been replaced by other commemorations, such as the Solemnity of Mary, Mother of God in the Roman Catholic Church or the Feast of the Holy Name of Jesus in the Lutheran Churches. There are, however, notable exceptions, such as among most Traditionalist Catholics, who reject Novus Ordo and other changes following Vatican II to varying degrees, thereby maintaining the feast as a Holy day of obligation.
