4. For if. We have stated how much it behoves us to know that the ungodly, who by their mischievous opinions corrupt the Church, cannot escape God’s vengeance; and this he proves especially by three remarkable examples of God's judgment, — that he spared not even angels, that he once destroyed the whole world by a deluge, that he reduced Sodom to ashes, and other neighboring cities. But Peter thought it sufficient to take as granted what ought to be never doubted by us, that is, that God is the judge of the whole world. It hence follows that the punishment he formerly inflicted on the ungodly and wicked, he will now also inflict on the like characters. For he can never be unlike himself, nor does he shew respect of persons, so as to forgive the same wickedness in one which he has punished in another; but he hates injustice and wrong equally, whenever it is found. (167)
For we must always bear in mind that there is a difference between God and men; for men indeed judge unequally, but God keeps the same course in judging. For that he forgives sins, this is done because he blots them out through repentance and faith. He therefore does not otherwise reconcile himself to us than by justifying us; for until sin is taken away, there is always an occasion of discord between us and Him.
As to the angels. The argument is from the greater to the less; for they were far more excellent than we are, and yet their dignity did not preserve them from the hand of God; much less then can mortal men escape, when they follow them in their impiety. But as Peter mentions here but briefly the fall of angels, and as he has not named the time and the manner and other circumstances, it behoves us soberly to speak on the subject. Most men are curious and make no end of inquiries on these things; but since God in Scripture has only sparingly touched on them, and as it were by the way, he thus reminds us that we ought to be satisfied with this small knowledge. And indeed they who curiously inquire, do not regard edification, but seek to feed their souls with vain speculations. What is useful to us, God has made known, that is, that the devils were at first created, that they might serve and obey God, but that through their own fault they apostatized, because they would not submit to the authority of God; and that thus the wickedness found in them was accidental, and not from nature, so that it could not be ascribed to God.
All this Peter declares very clearly, when he says that angels fell, though superior to men; and Jude is still more express when he writes, that they kept not their first estate, or their pre-eminence. [Jude 1:6.] Let those who are not satisfied with these testimonies have recourse to the Sorbonian theology, which will teach them respecting angels to satiety, so as to precipitate them to hell together with the devils.
Chains of darkness. This metaphor intimates that they are held bound in darkness until the last day. And the comparison is taken from malefactors, who, after having been condemned, suffer half of their punishment by the severity of the prison, until they are drawn forth to their final doom. We may hence learn, not only what punishment the wicked suffer after death, but also what is the condition of the children of God: for they calmly acquiesce in the hope of sure and perfect blessedness, though they do not as yet enjoy it; as the former suffer dreadful agonies on account of the vengeance prepared for them.
(167) The “if” at the beginning of the verse requires a corresponding clause. Some, as Piscator and Macknight, supply at the end of 2 Peter 2:7, “he will not spare thee,” or, “will he spare thee?” But there is no need of this, the corresponding clause is in 2 Peter 2:9; and this is our version. The deliverance of the just is there first mentioned, as that of Lot was the subject of the previous verse, and then the reservation of the unjust for judgment, examples of which he had before given. This sort of arrangement is common in Scripture. — Ed.
