1 John 2:7

Brethren, I write no new commandment unto you,.... Some understand this of faith, which this apostle calls a commandment, 1Jo 3:23; but it rather intends the commandment of love, especially to the brethren, of which the apostle says the same things as here in his second epistle, 1Jo 2:5; and this sense agrees both with what goes before and follows after, and is a considerable branch of the commandments of Christ to be kept, and of walking as he walked; and the word "brethren", prefixed to this account, may direct to, and strengthen this sense, though the Vulgate Latin and Syriac versions read, "beloved"; and so the Alexandrian copy, and others: and this commandment is said to be not a new one,but an old commandment, which ye had from the beginning; it being in its original a part of the eternal law of truth, founded upon the unalterable nature and eternal will of God, who is love itself, and requires it in all his creatures; being what was written on Adam's heart in a state of innocence, and a branch of the divine image stamped upon him; and is what was delivered in the law of Moses, for love to God and men is the sum and substance of that; and was taught by Christ and his apostles from the beginning of the Gospel dispensation; and was what these saints had been acquainted with, and influentially instructed in from their first conversion, being taught of God in regeneration to love one another; so that this was no novel doctrine, no upstart notion, no new law, but of the greatest and most venerable antiquity, and therefore to be regarded in the most respectful manner.
