Saint Peters Day

O CHRIST, "the Son of the Living God, Whom Saint Peter, stablished on the true Rock, truly confessed ; Grant us, we humbly beseech Thee, so to confess Thee, that, like him, we may obtain Thy blessing; Through Thy mercy, O Christ our God, Who, with the Father and the Holy Ghost, livest and reignest, ever one God, world without end. Amen.
