In our Episcopal Lectionary (and the Revised Common Lectionary, too) the first Sunday after the Epiphany (January 6) is dedicated to recalling the Baptism of our Lord. This event is recorded in all four Gospels. In today’s Collect we pray that we may keep the (Baptismal) Covenant we have made while we “boldly confess [Jesus] as Lord and Savior.”
Father in heaven, who at the baptism of Jesus in the River Jordan proclaimed him your beloved Son and anointed him with the Holy Spirit: Grant that all who are baptized into his Name may keep the covenant they have made, and boldly confess him as Lord and Savior; who with you and the Holy Spirit lives and reigns, one God, in glory everlasting. Amen.
Book of Common Prayer, 214
