Over time in the West, however, the celebration of the baptism of the Lord came to be commemorated as a distinct feast from Epiphany.
Then the feast was instituted, under the denomination "Commemoration of the Baptism of our Lord", for celebration on 13 January as a major double, using for the Office and the Mass those previously said on the Octave of the Epiphany, which Pius XII abolished; however, if the Commemoration of the Baptism of Our Lord occurred on Sunday, the Office and Mass were to be those of the Feast of the Holy Family without any commemoration.
[3] In his revision of the calendar five years later, Pope John XXIII kept on 13 January the "Commemoration of the Baptism of our Lord Jesus Christ", with the rank of a second-class feast.
In the Church of England, Ordinary Time does not begin until the day after the Presentation of Christ in the Temple.
It is not clear as to whether or not the Feast of the Baptism of our Lord[7] is the end of Christmastide for the Episcopal Church.
[10] Further, the Epiphany and the Baptism of Christ are viewed as specially connected,[11] allowing the interpretation that Christmastide does extend through and end with the Feast of our Lord's Baptism on the Sunday following the Epiphany.
