All Who Walk According to Truth are Children of God
To those, therefore, that have made progress in the word, He has proclaimed this utterance, bidding them dismiss anxious care of the things of this world, and exhorting them to adhere to the Father alone, in imitation of children. Wherefore also in what follows He says: “Take no anxious thought for the morrow; sufficient unto the day is the evil thereof.” Thus He enjoins them to lay aside the cares of this life, and depend on the Father alone. And he who fulfils this commandment is in reality a child and a son to God and to the world—to the one as deceived, to the other as beloved. And if we have one Master in heaven, as the Scripture says, then by common consent those on the earth will be rightly called disciples. For so is the truth, that perfection is with the Lord, who is always teaching, and infancy and childishness with us, who are always learning. Thus prophecy has honoured perfection, by applying to it the appellation man. For instance, by David, He says of the devil: “The Lord abhors the man of blood;” he calls him man, as perfect in wickedness. And the Lord is called man, because He is perfect in righteousness. Directly in point is the instance of the apostle, who says, writing the Corinthians: “For I have espoused you to one man, that I may present you as a chaste virgin to Christ,” whether as children or saints, but to the Lord alone. And writing to the Ephesians, he has unfolded in the clearest manner the point in question, speaking to the following effect: “Till we all attain to the unity of the faith, and of the knowledge of God, to a perfect man, to the measure of the stature of the fullness of Christ: that we be no longer children, tossed to and fro by every wind of doctrine, by the craft of men, by their cunning in stratagems of deceit; but, speaking the truth in love, may grow up to Him in all things,” — saying these things in order to the edification of the body of Christ, who is the head and man, the only one perfect in righteousness; and we who are children guarding against the blasts of heresies, which blow to our inflation; and not putting our trust in fathers who teach us otherwise, are then made perfect when we are the church, having received Christ the head. Then it is right to notice, with respect to the appellation of infant (νήπιος), that τὸ νήπιον is not predicated of the silly: for the silly man is called νηπύτιος: and νήπιος is νεήπιος (since he that is tender-hearted is called ἤπιος), as being one that has newly become gentle and meek in conduct. This the blessed Paul most clearly pointed out when he said, “When we might have been burdensome as the apostles of Christ, we were gentle (ἤπιοι) among you, as a nurse cherishes her children.” The child (νήπιος) is therefore gentle (ἤπιος), and therefore more tender, delicate, and simple, guileless, and destitute of hypocrisy, straightforward and upright in mind, which is the basis of simplicity and truth. For He says, “Upon whom shall I look, but upon him who is gentle and quiet?” For such is the virgin speech, tender, and free of fraud; whence also a virgin is wont to be called “a tender bride,” and a child “tender-hearted.” And we are tender who are pliant to the power of persuasion, and are easily drawn to goodness, and are mild, and free of the stain of malice and perverseness, for the ancient race was perverse and hard-hearted; but the band of infants, the new people which we are, is delicate as a child. On account of the hearts of the innocent, the apostle, in the Epistle to the Romans, owns that he rejoices, and furnishes a kind of definition of children, so to speak, when he says, “I would have you wise toward good, but simple towards evil.” For the name of child, νήπιος, is not understood by us privatively, though the sons of the grammarians make the νη a privative particle. For if they call us who follow after childhood foolish, see how they utter blasphemy against the Lord, in regarding those as foolish who have betaken themselves to God. But if, which is rather the true sense, they themselves understand the designation children of simple ones, we glory in the name. For the new minds, which have newly become wise, which have sprung into being according to the new covenant, are infantile in the old folly. Of late, then, God was known by the coming of Christ: “For no man knows God but the Son, and he to whom the Son shall reveal Him.”
In contradistinction, therefore, to the older people, the new people are called young, having learned the new blessings; and we have the exuberance of life's morning prime in this youth which knows no old age, in which we are always growing to maturity in intelligence, are always young, always mild, always new: for those must necessarily be new, who have become partakers of the new Word. And that which participates in eternity is wont to be assimilated to the incorruptible: so that to us appertains the designation of the age of childhood, a lifelong spring-time, because the truth that is in us, and our habits saturated with the truth, cannot be touched by old age; but Wisdom is ever blooming, ever remains consistent and the same, and never changes. “Their children,” it is said, “shall be borne upon their shoulders, and fondled on their knees; as one whom his mother comforts, so also shall I comfort you.” The mother draws the children to herself; and we seek our mother the Church. Whatever is feeble and tender, as needing help on account of its feebleness, is kindly looked on, and is sweet and pleasant, anger changing into help in the case of such: for thus horses' colts, and the little calves of cows, and the lion's cub, and the stag's fawn, and the child of man, are looked upon with pleasure by their fathers and mothers. Thus also the Father of the universe cherishes affection towards those who have fled to Him; and having begotten them again by His Spirit to the adoption of children, knows them as gentle, and loves those alone, and aids and fights for them; and therefore He bestows on them the name of child. The word Isaac I also connect with child. Isaac means laughter. He was seen sporting with his wife and helpmeet Rebecca by the prying king. The king, whose name was Abimelech, appears to me to represent a supramundane wisdom contemplating the mystery of sport. They interpret Rebecca to mean endurance. O wise sport, laughter also assisted by endurance, and the king as spectator! The spirit of those that are children in Christ, whose lives are ordered in endurance, rejoice. And this is the divine sport. “Such a sport, of his own, Jove sports,” says Heraclitus. For what other employment is seemly for a wise and perfect man, than to sport and be glad in the endurance of what is good— and, in the administration of what is good, holding festival with God? That which is signified by the prophet may be interpreted differently—namely, of our rejoicing for salvation, as Isaac. He also, delivered from death, laughed, sporting and rejoicing with his spouse, who was the type of the Helper of our salvation, the Church, to whom the stable name of endurance is given; for this cause surely, because she alone remains to all generations, rejoicing ever, subsisting as she does by the endurance of us believers, who are the members of Christ. And the witness of those that have endured to the end, and the rejoicing on their account, is the mystic sport, and the salvation accompanied with decorous solace which brings us aid.
