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.”[191] 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 hath 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;”[192] 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,”[193] 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 fulness 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 the stratagems of deceit; but, speaking the truth in love, may grow up to Him in all things,”[194]--saving 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 cherisheth her children.”[195] 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.
