{13} And of some have compassion, making a difference:

(13) Among those who wander and go astray, the godly have to use this choice, that they handle some of them gently, and that others being even in the very flame, they endeavour to save with severe and sharp instruction of the present danger: yet so, that they do in such sort abhor the wicked and dishonest, that they avoid even the least thought of them.

People's New Testament

Jude 1:22 And of some have compassion, making a difference. On some have mercy, who are in doubt (Revised Version). The thought is to be very gentle and pitiful to those disturbed by doubt.

Wesley's Notes

1:22 Meantime watch over others, as well as yourselves, and give them such help as their various needs require. For instance, Some, that are wavering in judgment, staggered by others' or by their own evil reasoning, endeavour more deeply to convince of the whole truth as it is in Jesus. Some snatch, with a swift and strong hand, out of the fire of sin and temptation. On others show compassion in a milder and gentler way; though still with a jealous fear, lest yourselves be infected with the disease you endeavour to cure.See, therefore, that while you love the sinners, ye retain the utmost abhorrence of their sins, and of any the least degree of, or approach to, them.

Jamieson-Fausset-Brown Bible Commentary

22, 23. None but those who "keep themselves" are likely to "save" others.

have compassion-So one oldest manuscript reads. But two oldest manuscripts, Vulgate, &c., read, "convict"; "reprove to their conviction"; "confute, so as to convince."

making a difference-The oldest manuscripts and versions read the accusative for the nominative, "when separating themselves" [Wahl], referring to Jude 19; or "when contending with you," as the Greek is translated, Jude 9.

Matthew Henry's Concise Commentary

1:17-23 Sensual men separate from Christ, and his church, and join themselves to the devil, the world, and the flesh, by ungodly and sinful practices. That is infinitely worse than to separate from any branch of the visible church on account of opinions, or modes and circumstances of outward government or worship. Sensual men have not the spirit of holiness, which whoever has not, does not belong to Christ. The grace of faith is most holy, as it works by love, purifies the heart, and overcomes the world, by which it is distinguished from a false and dead faith. Our prayers are most likely to prevail, when we pray in the Holy Ghost, under his guidance and influence, according to the rule of his word, with faith, fervency, and earnestness; this is praying in the Holy Ghost. And a believing expectation of eternal life will arm us against the snares of sin: lively faith in this blessed hope will help us to mortify our lusts. We must watch over one another; faithfully, yet prudently reprove each other, and set a good example to all about us. This must be done with compassion, making a difference between the weak and the wilful. Some we must treat with tenderness. Others save with fear; urging the terrors of the Lord. All endeavours must be joined with decided abhorrence of crimes, and care be taken to avoid whatever led to, or was connected with fellowship with them, in works of darkness, keeping far from what is, or appears to be evil.
