ANSWER:
DE PRINCIPIIS, BOOK 3 1.20 Whether it is possible for the apostle to contradict himself? And if this cannot be imagined of an apostle, how shall he appear, according to them, to be just in blaming those who committed fornication in Corinth, or those who sinned, and did not repent of their unchastity, and fornication, and uncleanness, which they had committed? How, also, does he greatly praise those who acted rightly, like the house of Onesiphorus, saying, “The Lord give mercy to the house of Onesiphorus; for he oft refreshed me, and was not ashamed of my chain: but, when he had come to Rome, he sought me out very diligently, and found me. The Lord grant unto him that he may find mercy of the Lord in that day.”[5] Now it is not consistent with apostolic gravity to blame him who is worthy of blame, i.e., who has sinned, and greatly to praise him who is deserving of praise for his good works; and again, as if it were in no one’s power to do any good or evil, to say that it was the Creator’s doing that every one should act virtuously or wickedly, seeing He makes one vessel to honour, and another to dishonour. And how can he add that statement, “We must all stand before the judgment-seat of Christ, that every one of us may receive in his body, according to what he hath done, whether it be good or bad? “[6] For what reward of good will be conferred on him who could not commit evil, being formed by the Creator to that very end? or what punishment will deservedly be inflicted on him who was unable to do good in consequence of the creative act of his Maker?[1] Then, again, how is not this opposed to that other declaration elsewhere, that “in a great house there are not only vessels of gold and silver, but also of wood and of earth, and some to honour, and some to dishonour. If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the Master’s use, prepared unto every good work.”[4] He, accordingly, who purges himself, is made a vessel unto honour, while he who has disdained to cleanse himself from his impurity is made a vessel unto dishonour. From such declarations, in my opinion, the cause of our actions can in no degree be referred to the Creator. For God the Creator makes a certain vessel unto honour, and other vessels to dishonour; but that vessel which has cleansed itself from all impurity He makes a vessel unto honour, while that which has stained itself with the filth of vice He makes a vessel unto dishonour. The conclusion from which, accordingly, is this, that the cause of each one’s actions is a pre-existing one; and then every one, according to his deserts, is made by God either a vessel unto honour or dishonour. Therefore every individual vessel has furnished to its Creator out of itself the causes and occasions of its being formed by Him to be either a vesselAugustinsnour or one unto dishonour(ANF, Vol. 4, p. 324).
It should be quite obvious that the Early Church Fathers are not closet Protestant.
