“For it had been better for them not to have known the way of justice, than after they have known it, to turn back from that holy commandment which was delivered to them.”

“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", Pe2 2:2, and "the right way", Pe2 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 Pe2 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 Rom 2:12.”

“For it had been better for them not to have known - For the reasons assigned above; because they have sinned against more mercy, are capable of more sin, and are liable to greater punishment. The holy commandment - The whole religion of Christ is contained in this one commandment, "Thou shalt love the Lord thy God with all thy heart, with all thy soul, with all thy mind, and with all thy strength; and thy neighbor as thyself." He who obeys this great commandment, and this by the grace of Christ is possible to every man, is saved from sinning either against his God or against his neighbor. Nothing less than this does the religion of Christ require.”

“the way of righteousness--"the way of truth" (Pe2 2:2). Christian doctrine, and "the knowledge of the Lord and Saviour." turn--back again; so the Greek. from the holy commandment--the Gospel which enjoins holiness; in opposition to their corruption. "Holy," not that it makes holy, but because it ought to be kept inviolate [TITTMANN]. delivered--once for all; admitting no turning back.”
