Almighty and everlasting Father, you have given the Holy Spirit to abide with us for ever: Bless, we pray, with his grace and presence, the bishops and other clergy and the laity here (or now, or soon to be) assembled in your Name, that your Church, being preserved in true faith and godly discipline, may fulfill all the mind of him who loved it and gave himself for it, your Son Jesus Christ our Savior; who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.
