21. Nay, that very declaration, that from the same lump a vessel is formed both to honour and to dishonour, will not push us hard; for we assert that the nature of all rational souls is the same, as one lump of clay is described as being under the treatment of the potter. Seeing, then, the nature of rational creatures is one, God, according to the previous grounds of merit, created and formed out of it, as the potter out of the one lump, some persons to honour and others to dishonour. Now, as regards the language of the apostle, which he utters as if in a tone of censure, “Nay but, O man, who art thou that repliest against God?” he means, I think, to point out that such a censure does not refer to any believer who lives rightly and justly, and who has confidence in God, i.e. to such an one as Moses was, of whom Scripture says that “Moses spake, and God answered him by a voice;” and as God answered Moses, so also does every saint answer God. But he who is an unbeliever, and loses confidence in answering before God owing to the unworthiness of his life and conversation, and who, in relation to these matters, does not seek to learn and make progress, but to oppose and resist, and who, to speak more plainly, is such an one as to be able to say those words which the apostle indicates, when he says, “Why, then, does He yet find fault? for who will resist His will?”—to such an one may the censure of the apostle rightly be directed, “Nay but, O man, who art thou that repliest against God?” This censure accordingly applies not to believers and saints, but to unbelievers and wicked men.
