3 We have clearly fallen on the evil times prophesied by the Apostle; for nowadays teachers are sought after who preach not God but a creature. And men are more zealous for what they themselves desire, than for what the sound faith teaches. So far have their itching ears stirred them to listen to what they desire, that for the moment that preaching alone rules among their crowd of doctors which estranges the Only-begotten God from the power and nature of God the Father, and makes Him in our faith either a God of the second order, or not a God at all; in either case a damning profession of impiety, whether one profess two Gods by making different grades of divinity; or else deny divinity altogether to Him Who drew His nature by birth from God. Such doctrines please those whose ears are estranged from the hearing of the truth and turned to fables, while the hearing of this our sound faith is not endured, and is driven bodily into exile with its preachers.
