Andreas of Caesarea : Peter means that after they went astray they were able to lead others astray after them, but that in the end they will have to pay the price of their wickedness. — CATENA Bede : Receiving the reward of injustice. The reward of injustice is the punishment he speaks of, which the works of injustice deserve, especially in those who, while they themselves are slaves to the corruption of the flesh, nonetheless blaspheme the conduct of those who live chastely, though they themselves are held by insane errors, they do not cease to disparage those who hold sound understanding. — Commentary on the Catholic Epistles Bede : Thinking of the delights of the day as impurities and stains. Pleasure is taken both in a good and an evil sense. In the good sense, it is called the paradise of delight, and as it is sung in the psalm: And they shall drink from the torrent of Your pleasure (Psalms 35). In an evil sense, as Solomon says: For youth and pleasure are vain (Ecclesiastes 11). But it is also used indifferently, according to what Sarah said: After I am old, and my lord is old, shall I have pleasure? (Genesis 18). Therefore, good pleasure is rightly called the delight of the day, by which the saints delight in the Lord. However, evil pleasure belongs to the night, when the wicked perversely delight in performing deeds of darkness. It is rightly said of the unjust that they think of the pleasure of the day, the delights of impurity and stain, because many are so lazy, perverse, and shameless that, whilst engaging in the most impure and detestable pleasures, they nonetheless judge these to be the best and almost luminous. Some join the first word of this verse to the preceding verse, reading thus: Receiving the reward of unrighteousness as pleasure, and expound it according to what the apostle Paul said: God gave them over to the desires of their hearts in impurity, to dishonor their bodies among themselves (Romans 1). And a little later: Committing shameless acts, receiving in themselves the due penalty of their error. And as they did not see fit to acknowledge God, God gave them up to a debased mind, to do what ought not to be done (Ibid.). But we thought it right to follow the distinction we found in the works of the blessed Pope Gregory. — Commentary on the Catholic Epistles Oecumenius : Spots and blemishes party in their errors against you, having eyes full of adultery, and who cannot cease from sin, enticing unstable souls. "Spots and blemishes." The order is taken as follows: Spots and blemishes (Σπίλοι καὶ μῶμοι) are the heart of those who are exercised in plunder, that is, exercised through plunder, accursed children, assaulting you, having eyes full of adultery, and who cannot cease from sin: they entice unstable souls, which Paul also called women burdened with sins. (2 Tim. 3:6) Furthermore, these have forsaken the right way, and have gone astray following the way of Balaam the son of Bosor, and the rest. These are wells without water, clouds carried with a tempest, etc. (2 Peter 2:17) And why is darkness reserved for them in the future world? Because of their immense vanity, by which they entice those who had previously walked in error, and had truly fled from it: so that through filthiness and the desires of the flesh, they return like a dog to its vomit. (Prov. 26:11) But those who are placed in the middle declare and confirm this vanity. "Spots and blemishes." They have nothing that is fixed in purity, but like stains on a clean garment, they cling to long-standing conversation and defile everything: when they have drawn some away and have been able to make them shameless, those who are together, men and women, they consider this act a delight, satisfying their own lust: but also, they say, those who are dining with you do this not out of love, or because they share (as they say) in salt11, but to find this time suitable for deception among women. For these, having eyes, look at nothing but adulteresses, and in this, they sin continually, like children of abomination or abominable ones, ensnaring unstable souls. — Commentary on 2 Peter
