Book of Common Prayer (page 80)

The Priest stands and says

Almighty God have mercy on you, forgive you all your sins
through our Lord Jesus Christ, strengthen you in all
goodness, and by the power of the Holy Spirit keep you in
eternal life. Amen.

*A deacon or lay person using the preceding form remains kneeling, and
substitutes "us" for "you" and "our" for "your."

The Invitatory and Psalter

All stand

Officiant Lord, open our lips.
People And our mouth shall proclaim your praise.

Officiant and People

Glory to the Father, and to the Son, and to the Holy Spirit: as
it was in the beginning, is now, and will be for ever. Amen.

Except in Lent, add Alleluia.

One of the following Antiphons may be sung or said with the Invitatory
Psalm

Our King and Savior now draws near: Come let us adore him.

On the Twelve Days of Christmas
