In
Jesus of Nazareth: From the Baptism in the Jordan to the Transfiguration, Pope Benedict writes:
The Eastern Church has further developed and deepened this understanding of Jesus' Baptism in her liturgy and in her theology of icons. She sees a deep connection between the content of the feast of Epiphany (the heavenly voice proclaiming Jesus to be the Son of God: for the East the Epiphany is the day of the Baptism) and Easter. She sees Jesus' remark to John that "it is fitting for us to fulfill all righteousness" (Mt 3:15) as the anticipation of his prayer to the Father in Gethsemane: "My father ... not as I will, but as thou wilt" (Mt 26:39) The liturgical hymns for January 3 correspond to those for Wednesday in Holy Week; the hymns for January 4 to those for Holy Thursday; the hymns for January 5 to those for Good Friday and Holy Saturday. (Emphasis added)
Is this a reference to the hymns of the Byzantine tradition? If so, can anyone provide me with examples of these corresponding hymns?
