"But if any one desires to learn exactly the truth of our preaching, let him come to hear, and let him ascertain what the true Prophet is; and then at length all doubtfulness will cease to him, unless with obstinate mind he resist those things which he finds to be true. For there are some whose only object it is to gain the victory in any way whatever, and who seek praise for this rather than their salvation. These ought not to have a single word addressed to them, lest both the noble word suffer injury, and condemn to eternal death him who is guilty of the wrong done to it. For what is there in respect of which any one ought to oppose our preaching? or in respect of which the word of our preaching is found to be contrary to the belief of what is true and honourable? It says that the God the Father, the Creator of all, is to be honoured, as also His Son, who alone knows Him and His will, and who alone is to be believed concerning all things which He has enjoined. For He alone is the law and the Lawgiver, and the righteous Judge, whose law decrees that God, the Lord of all, is to be honoured by a sober, chaste, just, and merciful life, and that all hope is to be placed in Him alone.
