All Who Walk According to Truth are Children of God
That, then, Pædagogy is the training of children (παίδων ἀγωγή), is clear from the word itself. It remains for us to consider the children whom Scripture points to; then to give the pædagogue charge of them. We are the children. In many ways Scripture celebrates us, and describes us in manifold figures of speech, giving variety to the simplicity of the faith by diverse names. Accordingly, in the Gospel, “the Lord, standing on the shore, says to the disciples”— they happened to be fishing— “and called aloud, Children, have you any meat?” — addressing those that were already in the position of disciples as children. “And they brought to Him,” it is said, “children, that He might put His hands on them and bless them; and when His disciples hindered them, Jesus said, Suffer the children, and forbid them not to come to Me, for of such is the kingdom of heaven.” What the expression means the Lord Himself shall declare, saying, “Unless you be converted, and become as little chidren, you shall not enter into the kingdom of heaven;” not in that place speaking figuratively of regeneration, but setting before us, for our imitation, the simplicity that is in children.
The prophetic spirit also distinguishes us as children. “Plucking,” it is said, “branches of olives or palms, the children went forth to meet the Lord, and cried, saying, Hosanna to the Son of David! Blessed is He that comes in the name of the Lord;” light, and glory, and praise, with supplication to the Lord: for this is the meaning of the expression Hosanna when rendered in Greek. And the Scripture appears to me, in allusion to the prophecy just mentioned, reproachfully to upbraid the thoughtless: “Have you never read, Out of the mouths of babes and sucklings You have perfected praise?” In this way the Lord in the Gospels spurs on His disciples, urging them to attend to Him, hastening as He was to the Father; rendering His hearers more eager by the intimation that after a little He was to depart, and showing them that it was requisite that they should take more unsparing advantage of the truth than ever before, as the Word was to ascend to heaven. Again, therefore, He calls them children; for He says, “Children, a little while I am with you.” And, again, He likens the kingdom of heaven to children sitting in the market-places and saying, “We have piped unto you, and you have not danced; we have mourned, and you have not lamented;” and whatever else He added agreeably thereto. And it is not alone the Gospel that holds these sentiments. Prophecy also agrees with it. David accordingly says, “Praise, O children, the Lord; praise the name of the Lord.” It says also by Esaias, “Here am I, and the children that God has given me.” Are you amazed, then, to hear that men who belong to the nations are sons in the Lord's sight? You do not in that case appear to give ear to the Attic dialect, from which you may learn that beautiful, comely, and freeborn young maidens are still called παιδίσκαι, and servant-girls παιδισκάρια; and that those last also are, on account of the bloom of youth, called by the flattering name of young maidens.
And when He says, “Let my lambs stand on my right,” He alludes to the simple children, as if they were sheep and lambs in nature, not men; and the lambs He counts worthy of preference, from the superior regard He has to that tenderness and simplicity of disposition in men which constitutes innocence. Again, when He says, “as suckling calves,” He again alludes figuratively to us; and “as an innocent and gentle dove,” the reference is again to us. Again, by Moses, He commands “two young pigeons or a pair of turtles to be offered for sin;” thus saying, that the harmlessness and innocence and placable nature of these tender young birds are acceptable to God, and explaining that like is an expiation for like. Further, the timorousness of the turtle-doves typifies fear in reference to sin.
And that He calls us chickens the Scripture testifies: “As a hen gathers her chickens under her wings.” Thus are we the Lord's chickens; the Word thus marvellously and mystically describing the simplicity of childhood. For sometimes He calls us children, sometimes chickens, sometimes infants, and at other times sons, and “a new people,” and “a recent people.” “And my servants shall be called by a new name” (a new name, He says, fresh and eternal, pure and simple, and childlike and true), which shall be blessed on the earth. And again, He figuratively calls us colts unyoked to vice, not broken in by wickedness; but simple, and bounding joyously to the Father alone; not such horses “as neigh after their neighbours' wives, that are under the yoke, and are female-mad;” but free and new-born, jubilant by means of faith, ready to run to the truth, swift to speed to salvation, that tread and stamp under foot the things of the world.
“Rejoice greatly, O daughter of Sion; tell aloud, O daughter of Jerusalem: behold, your King comes, just, meek, and bringing salvation; meek truly is He, and riding on a beast of burden, and a young colt.” It was not enough to have said colt alone, but He added to it also young, to show the youth of humanity in Christ, and the eternity of simplicity, which shall know no old age. And we who are little ones being such colts, are reared up by our divine colt-tamer. But if the new man in Scripture is represented by the ass, this ass is also a colt. “And he bound,” it is said, “the colt to the vine,” having bound this simple and childlike people to the word, whom He figuratively represents as a vine. For the vine produces wine, as the Word produces blood, and both drink for health to men— wine for the body, blood for the spirit.
And that He also calls us lambs, the Spirit by the mouth of Isaiah is an unimpeachable witness: “He will feed His flock like a shepherd, He will gather the lambs with His arm,” — using the figurative appellation of lambs, which are still more tender than sheep, to express simplicity. And we also in truth, honouring the fairest and most perfect objects in life with an appellation derived from the word child, have named training παιδεία, and discipline παιδαγωγία. Discipline (παιδαγωγία) we declare to be right guiding from childhood to virtue. Accordingly, our Lord revealed more distinctly to us what is signified by the appellation of children. On the question arising among the apostles, “which of them should be the greater,” Jesus placed a little child in the midst, saying, “Whosoever, shall humble himself as this little child, the same shall be the greater in the kingdom of heaven.” He does not then use the appellation of children on account of their very limited amount of understanding from their age, as some have thought. Nor, if He says, “Unless you become as these children, you shall not enter into the kingdom of God,” are His words to be understood as meaning “without learning.” We, then, who are infants, no longer roll on the ground, nor creep on the earth like serpents as before, crawling with the whole body about senseless lusts; but, stretching upwards in soul, loosed from the world and our sins, touching the earth on tiptoe so as to appear to be in the world, we pursue holy wisdom, although this seems folly to those whose wits are whetted for wickedness. Rightly, then, are those called children who know Him who is God alone as their Father, who are simple, and infants, and guileless, who are lovers of the horns of the unicorns.
