Romans 9:19

Thou wilt say, therefore, to me, &c. The apostle makes objection, that if God call some and harden, or even permit others to be hardened, and no one resisteth, or can hinder his absolute will, why should God complain that men are not converted? St. Paul first puts such rash and profane men in mind, that is unreasonable and impertinent for creatures to murmur and dispute against God their Creator, when they do not comprehend the ways of his providence. --- O man, [4] who art thou that repliest against God? This might stop the mouths, and quiet the minds of every man, when he cannot comprehend the mysteries of predestination, of God's foreknowledge, his decrees and graces, or the manner of reconciling them with human liberty. He may cry out with St. Paul again, (chap. xi. 33.) O the riches of the wisdom, and of the knowledge of God! how incomprehensible are his judgments, and how unsearchable his ways! --- Shall the thing formed, &c. Hath not the potter power, &c.[5] To teach men that they ought not to complain against God and his providence, when they cannot comprehend his works, he puts them in mind of their origin. Every one may say to God, with the prophet Isaias, (vi. 48.) Lord, thou art our Father, and we are but clay; thou art our Maker who framed us, and we are all of us the work of thy hands. Hath not the potter power as he pleaseth, out of the same lump of clay to make some vessels for honourable uses, and some for less honourable. St. John Chrysostom observes very well, that this comparison must not be extended further than the apostle designed; which was to teach us, how submissive we ought to be to God, in what we do not understand; but we must not pretend from hence, nor from any expression in this chapter, as divers heretics have done, that as vessels of clay are destitute of free will and liberty, so are men. This is against the doctrine of the Catholic Church, and against the Scriptures, in many places. (Witham) --- The potter. This similitude is used, only to shew that we are not to dispute with our Maker: nor to reason with him why he does not give as much grace to one as to another: for since the whole lump of our clay is vitiated by sin, it is owing to his goodness and mercy that he makes out of it so many vessels of honour; and it is no more than just that others, in punishment of their unrepented sins, should be given up to be vessels of dishonour.
