“"But some," he says, "save, plucking them from the fire;" "but of some have compassion in fear," that is, teach those who fall into the fire to free themselves. "Hating," he says, "that spotted garment, which is carnal:" that of the soul, namely; the spotted garment is a spirit polluted by carnal lusts.”

“What if, even here, you should conceive to reply that communion is indeed denied to sinners, very especially such as had been "polluted by the flesh," but (only) for the present; to be restored, to wit, as the result of penitential suing: in accordance with that clemency of God which prefers a sinner's repentance to his death? -for this fundamental ground of your opinion must be universally attacked.”

“And others save with fear,.... Meaning false teachers, who lead others into errors, and such as give themselves over unto sin, whether teachers or hearers, and who are obstinate and irreclaimable; even such as these, means should be used to save, if possible, by sharp admonitions and severe language; by denouncing the awful judgments of God, which threaten them; by inflicting on them church censures in a terrible manner; by declaring the terrors of the Lord, and of hell, and of everlasting damnation: pulling them out of the fire; of their soul destroying doctrines, and of their filthy and unnatural lusts, and as it were out of the fire of hell, of which they are in great danger: hating even the garment spotted, by the flesh; by which may be meant the conversation of those men, even their filthy conversation, which is to be hated, though their persons are not; but all ways and means should be used to save them; and this is one way, by showing a dislike unto, and a resentment at their wicked way of living, excluding them from church communion for it, and shunning all conversation with them. The allusion is not to garments defiled by profluvious persons, or menstruous women, as some think, but to garments spotted with nocturnal pollutions, or through unnatural lusts, which these persons were addicted to (l). It was reckoned very dishonourable for religious persons, in the time of divine service, or on a sabbath day, to have on a garment spotted with any thing; if a priest's garments were spotted, and he performed service in them, that service was not right (m); and if a disciple of a wise man had any grease on his garments (on a sabbath day), he was guilty of death (n), (l) Vid.

“And others save with fear - "Some of them snatch from the fire: but when they repent, have mercy upon them in fear." - Syriac. "And some of them rebuke for their sins; and on others have mercy when they are convicted; and others save from the fire and deliver them." - Erpen's Arabic. Mr. Wesley's note has probably hit the sense. "Meantime watch over others as well as yourselves; and give them such help as their various needs require. For instance, 1. Some that are wavering in judgment, staggered by others' or by their own evil reasoning, endeavor more deeply to convince of the truth as it is in Jesus. 2. Some snatch with a swift and strong hand out of the fire of sin and temptation. 3. On others show compassion, in a milder and gentler way; though still with a jealous fear, lest you yourselves be infected with the disease you endeavor to cure. See therefore that, while ye love the sinners, ye retain the utmost abhorrence of their sins, and of any, the least degree of or approach to them." Having even the garment spotted by the flesh - Fleeing from all appearance of evil. Dictum sumptum, ut apparet, a mulieribus sanguine menstruo pollutis, quarum vestes etiam pollutae censebantur: or there may be an allusion to a case of leprosy, for that infected the garments of the afflicted person, and these garments were capable of conveying the contagion to others.”

“save with fear--The oldest manuscripts do not read "with fear" in this position: but after "snatching them out of the fire" (with which, compare Amo 4:11; Co1 3:15; Zac 3:2, said of a most narrow escape), they add the following words, forming a THIRD class, "and others compassionate with (IN) fear." Three kinds of patients require three kinds of medical treatment. Ministers and Christians are said to "save" those whom they are made the instruments of saving; the Greek for "save" is present, therefore meaning "try to save." Jude already (Jde 1:9) had reference to the same passage (Zac 3:1-3). The three classes are: (1) those who contend with you (accusative case in oldest manuscripts), whom you should convict; (2) those who are as brands already in the fire, of which hell-fire is the consummation: these you should try to save by snatching them out; (3) those who are objects of compassion, whom accordingly you should compassionate (and help if occasion should offer), but at the same time not let pity degenerate into connivance at their error. Your compassion is to be accompanied "with fear" of being at all defiled by them. hating--Even hatred has its legitimate field of exercise. Sin is the only thing which God hates: so ought we. even the garment--a proverbial phrase: avoiding the most remote contact with sin, and hating that which borders on it. As garments of the apostles wrought miracles of good in healing, so the very garment of sinners metaphorically, that is, anything brought into contact with their pollution, is to be avoided. Compare as to lepers and other persons defiled, Lev 13:52-57; Lev 15:4-17 : the garments were held polluted; and anyone touching them was excluded, until purified, from religious and civil communion with the sanctified people of Israel. Christians who received at baptism the white garment in token of purity, are not to defile it by any approach to what is defiled.”

“But save those. Those who are not condemned before God, but even so are near to falling into the fire, teach them to free themselves. In fear. This is to be joined to all those foregoing things. For, etc., up to lest perhaps he prove, more than is just, either severe or indulgent. Hating it. We ought not to hate our body, but its being stained, so that we may render it unstained, so that from carnal it may be made spiritual. Which is to be accomplished not by the power of our own choice, but by the grace of God.”
