I John 2:12

little children--Greek, "little sons," or "dear sons and daughters"; not the same Greek as in Jo1 2:13, "little children," "infants" (in age and standing). He calls ALL to whom he writes, "little sons" (Jo1 2:1, Greek; Jo1 2:28; Jo1 3:18; Jo1 4:4; Jo1 5:21); but only in Jo1 2:13, Jo1 2:18 he uses the term "little children," or "infants." Our Lord, whose Spirit John so deeply drank into, used to His disciples (Joh 13:33) the term "little sons," or dear sons and daughters; but in Joh 21:5, "little children." It is an undesigned coincidence with the Epistle here, that in John's Gospel somewhat similarly the classification, "lambs, sheep, sheep," occurs. are forgiven--"have been, and are forgiven you": ALL God's sons and daughters alike enjoy this privilege.

This new command of holy love, with the incentives thereto, may possibly be directed to the several ranks of disciples that are here accosted. The several graduates in the Christian university, the catholic church, must be sure to preserve the bond of sacred love. Or, there being an important dehortation and dissuasion to follow, without the observance of which vital religion in the love of God and love of the brethren cannot subsist, the apostle may justly seem to preface it with a solemn address to the several forms or orders in the school of Christ: let the infants or minors, the adults, the seniors (or the adepti, the teleioi, the most perfect), in the Christian institution, know that they must not love this world; and so, I. We have the address itself made to the various forms and ranks in the church of Christ. All Christians are not of the same standing and stature; there are babes in Christ, there are grown men, and old disciples. As these have their peculiar states, so they have their peculiar duties; but there are precepts and a correspondent obedience common to them all, as particularly mutual love and contempt of the world. We see also that wise pastors will judiciously distribute the word of life, and give to the several members of Christ's family their several suitable portions: I write unto you children, fathers, and young men. In this distribution the apostle addresses, 1. The lowest in the Christian school: I write unto you, little children, Jo1 2:12. There are novices in religion, babes in Christ, those who are learning the rudiments of Christian godliness. The apostle may seem to encourage them by applying to them first; and it may be useful to the greater proficients to hear what is said to their juniors; elements are to be repeated; first principles…

2:12-14 John gives three classes of believers at various stages of spiritual maturity: God’s children, the young in the faith (literally young people), and the mature in the faith (literally fathers).
