Almighty God, only giver of all mercies, whose Son, Jesus Christ, has taught us how to pray aright: Save us, we beseech thee, from all presumption in our prayer, and grant unto us the grace of humility and contrition; that we may, sharing the vision of thine apostle Saint Paul, know that it is by the grace of God alone that we are what we are, and that we can do nothing but through the strengthening of thy Son, Christ our Lord; who liveth and reigneth with thee in the unity of the Holy Spirit, ever one God, world without end.
