A Prayer on the Feast Day for the Confession of St. Peter

Almighty Father, who didst inspire Simon Peter, first among the apostles, to confess Jesus as Messiah and Son of the Living God: Keep thy Church steadfast upon the rock of this faith, that in unity and peace we may proclaim the one truth and follow the one Lord, our Savior Jesus Christ; who liveth and reigneth with thee and the Holy Spirit, one God, now and for ever.
