At the Gospel
ALMIGHTY God, Thou source of all truth, holiness, and justice; having spoken in the Old Law by the mouth of Thy prophets, Thou spokest in the fulness of time through Thy divine Son Jesus Christ, and speakest now through Thy holy Church, appointed by Thee the Teacher of truth. We thank Thee for the saving doctrines entrusted to her for our good, and implore Thy grace to practise them and to please Thee by all our actions.
