Where do you find in the Old Testament or in the Gospel the Trinity, or consubstantiality, or one Godhead, or three persons, or the one substance of Christ, or His two natures, expressed in so many words? Still, as they are contained in what Scripture does say, and defined by the holy fathers, we receive them and anathematise those who do not.
