“Children,” “fathers,” “young men,” and “little ones”: by these ages he indicates degrees of spiritual perfection and qualities more than natural ages. Yet the latter cannot be excluded, since one age often coincides with another, the natural with the spiritual. In the Kingdom of Christ it can happen, and truly does happen, that elders in age may be children, or even infants, in intellectual and moral perfection. The reverse can also occur. “Children”: in this epistle the Apostle more than once addresses his readers, the Christians, with this name, “children.” He uses it in the sense of the closest relation between them, as a father to his children in spirit and faith, or as a beloved teacher to beloved disciples. Thus in 1 Jn 2:1, 18, 28; 3:1, 18, and the like. But in the present place the address is made not in this general sense, but in a more particular sense. Here it denotes children by age, of course spiritual age, though in a certain correspondence with natural age in the sense indicated. That children by age are meant is clear from the fact that they are set alongside fathers, young men, and little ones. It is likewise clear from the construction of the speech, especially in Greek: “I write to you, children; I write to you, fathers,” and so forth. In giving instruction to Christians according to ages, the Apostle points out a special motive for each age. Each age is not to cling to the world or to what is in the world. Yet this is done in such a way that no strict division or boundary should be supposed between them. Rather, the motive proper to one age is also proper to the others. They differ from one another only by predominance, not by exclusion. Thus, for example, children have been forgiven their sins, but fathers and little ones have also been forgiven. Or, little ones have known the Father, but children, fathers, and young men have also known Him. The perfections and qualities chiefly proper to one or another age are characterized, but not exclusively. “Children, your sins are forgiven you.” Childhood, together with infancy, is the first age. In it the faithful, being reborn in the font of baptism, receive, or have already received, forgiveness of sins. Through this they have been reconciled to God by the death on the Cross of Christ the Savior. Therefore, having received forgiveness of sins for Christ’s name’s sake, they must from the earliest age, both spiritual and natural, wholly dedicate themselves to God and Christ by fulfilling the commandments. They must reject service to the world and to what is in the world. The forgiveness of their sins for Christ’s name’s sake is their chief motive, in accordance with their age, to love God, Christ, and neighbor, and not to love the world or anything in it.
