Let the heretic Eunomius [ed. note: Eunomius, the chief of the Anomaean branch of the Arians, taught that there was no mystery about the Divine nature. He is opposed by St. Basil, and by St. Chrysostom in his Homilees on ‘the incomprehensible nature of God.’] therefore blush hereat who claims to himself such a knowledge of the Father and the Son, as they have one of another. But if he argues from what follows, and props up his madness by that, “And he to whom the Son will reveal him,” it is one thing to know what you know by equality with God, another to know it by His vouchsafing to reveal it.
