(21) It had been better for them not to have known.--There are many things of which the well-known lines.

"'Tis better to have loved and lost,

Than never to have loved at all,"

do not hold good. To have loved a great truth, to have loved a high principle, and after all to lose them, is what often causes the shipwreck of a life. To have loved Jesus Christ and lost Him is to make shipwreck of eternal life.

The way of righteousness.--The life of the Christian. That which from a doctrinal point of view is "the way of truth" (2Peter 2:2), from a moral point of view is "the way of righteousness." So also "the faith delivered to the saints" of Jude 1:3, is the doctrinal equivalent of "the holy commandment delivered unto them" of this verse.

Verse 21. - For it had been better for them not to have known the way of righteousness; better, as in the Revised Version, for it were better. (For this use of the imperfect indicative, see Winer, 3:41, 2, a.) The verb ἐπεγνωκέκαι, "to have known," here, and the participle ἐπιγνοῦσιν, "after they have known," in the next clause, correspond with the noun ἐπίγνωσις of the preceding, and, like that, imply that these unhappy men once had the full knowledge of Christ. (For "the way, of righteousness," compare "the way of truth" in verse 2, and note there.) Than, after they have known it, to turn from the holy commandment delivered unto them. The manuscripts exhibit some slight variations here: the Sinaitic and Alexandrine give "to turn back." By "the holy commandment" St. Peter means the whole moral Law, which the Lord enforced and widened in his sermon on the mount; from this the false teachers turned away. For the word "delivered" (παραδοθείσης), comp. Jude 1:3. Like the corresponding word παράδοσις, tradition (2 Thessalonians 3:6), it implies the oral transmission of Christian teaching in the first ages (comp. also 1 Peter 1:18).

2:17-22 The word of truth is the water of life, which refreshes the souls that receive it; but deceivers spread and promote error, and are set forth as empty, because there is no truth in them. As clouds hinder the light of the sun, so do these darken counsel by words wherein there is no truth. Seeing that these men increase darkness in this world, it is very just that the mist ofdarkness should be their portion in the next. In the midst of their talk of liberty, these men are the vilest slaves; their own lusts gain a complete victory over them, and they are actually in bondage. When men are entangled, they are easily overcome; therefore Christians should keep close to the word of God, and watch against all who seek to bewilder them. A state of apostacy is worse than a state of ignorance. To bring an evil report upon the good way of God, and a false charge against the way of truth, must expose to the heaviest condemnation. How dreadful is the state here described! Yet though such a case is deplorable, it is not utterly hopeless; the leper may be made clean, and even the dead may be raised. Is thy backsliding a grief to thee? Believe in the Lord Jesus, and thou shalt be saved.For it had been better for them,.... Not that ignorance is good, or to be excused; but it would have been a lesser evil, and not so much aggravated:

not to have known the way of righteousness; the same with "the way of truth", 2 Peter 2:2, and "the right way", 2 Peter 2:15, the Gospel, which points out the way and method of a sinner's justification before God, which is not by the works of the law, but by the righteousness of Christ imputed to them, and received by faith; and which teaches men to live soberly, righteously, and godly; and a large, notional, though not an experimental knowledge, these apostates had of the word and doctrine of righteousness, and indeed of the whole of the Christian religion, which may truly go by this name:

than after they have known it; owned, embraced, and professed it:

to turn: the Vulgate Latin version, and some copies, as the Alexandrian and others, add, to that which is behind; to their former lusts, or errors, or worse, which they had turned their backs upon externally:

from the holy commandment delivered unto them; by the commandment is meant the Gospel also, see 2 Peter 3:2; called holy, because of its nature and influence, and in opposition to the pollutions of the world; and which is the faith once delivered, Jde 1:3, and which they received, as delivered to them; and, particularly, the ordinances of it, which they once submitted to, kept, and observed, as they were delivered to them, but now relinquished, or corrupted: wherefore, it would have been better for them to have been in their former ignorance, either in Judaism, or in Gentilism, since proportionate to a man's light is his guilt, and so his punishment, see Romans 2:12.
