One week after Christmas, on January 1, we celebrate this day when the Child was circumcised and formally named.

Eternal Father, you gave to your incarnate Son the holy name
of Jesus to be the sign of our salvation: Plant in every heart,
we pray, the love of him who is the Savior of the world, our
Lord Jesus Christ; who lives and reigns with you and the Holy
Spirit, one God, in glory everlasting. Amen. (BPC 213)
