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.
