De Principiis

³ The Only-begotten of God, therefore, through whom, as the previous course of the discussion has shown, all things were made, visible and invisible, according to the view of Scripture, both made all things, and loves what He made. For since He is Himself the invisible image of the invisible God, He conveyed invisibly a share in Himself to all His rational creatures, so that each one obtained a part of Him exactly proportioned to the amount of affection with which he regarded Him. But since, agreeably to the faculty of free-will, variety and diversity characterized the individual souls, so that one was attached with a warmer love to the Author of its being, and another with a feebler and weaker regard, that soul (anima) regarding which Jesus said, “No one shall take my life (animam) from me,” inhering, from the beginning of the creation, and afterwards, inseparably and indissolubly in Him, as being the Wisdom and Word of God, and the Truth and the true Light, and receiving Him wholly, and passing into His light and splendour, was made with Him in a pre-eminent degree one spirit, according to the promise of the apostle to those who ought to imitate it, that “he who is joined in the Lord is one spirit.” This substance of a soul, then, being intermediate between God and the flesh— it being impossible for the nature of God to intermingle with a body without an intermediate instrument— the God-man is born, as we have said, that substance being the intermediary to whose nature it was not contrary to assume a body. But neither, on the other hand, was it opposed to the nature of that soul, as a rational existence, to receive God, into whom, as stated above, as into the Word, and the Wisdom, and the Truth, it had already wholly entered. And therefore deservedly is it also called, along with the flesh which it had assumed, the Son of God, and the Power of God, the Christ, and the Wisdom of God, either because it was wholly in the Son of God, or because it received the Son of God wholly into itself. And again, the Son of God, through whom all things were created, is named Jesus Christ and the Son of man. For the Son of God also is said to have died— in reference, viz., to that nature which could admit of death; and He is called the Son of man, who is announced as about to come in the glory of God the Father, with the holy angels. And for this reason, throughout the whole of Scripture, not only is the divine nature spoken of in human words, but the human nature is adorned by appellations of divine dignity. More truly indeed of this than of any other can the statement be affirmed, “They shall both be in one flesh, and are no longer two, but one flesh.” For the Word of God is to be considered as being more in one flesh with the soul than a man with his wife. But to whom is it more becoming to be also one spirit with God, than to this soul which has so joined itself to God by love as that it may justly be said to be one spirit with Him?

4. That the perfection of his love and the sincerity of his deserved affection formed for it this inseparable union with God, so that the assumption of that soul was not accidental, or the result of a personal preference, but was conferred as the reward of its virtues, listen to the prophet addressing it thus: “You have loved righteousness, and hated wickedness: therefore God, your God, has anointed you with the oil of gladness above your fellows.” As a reward for its love, then, it is anointed with the oil of gladness; i.e., the soul of Christ along with the Word of God is made Christ. Because to be anointed with the oil of gladness means nothing else than to be filled with the Holy Spirit. And when it is said “above your fellows,” it is meant that the grace of the Spirit was not given to it as to the prophets, but that the essential fullness of the Word of God Himself was in it, according to the saying of the apostle, “In whom dwelt all the fullness of the Godhead bodily.” Finally, on this account he has not only said, “You have loved righteousness;” but he adds, “and You have hated wickedness.” For to have hated wickedness is what the Scripture says of Him, that “He did no sin, neither was any guile found in His mouth,” and that “He was tempted in all things like as we are, without sin.” Nay, the Lord Himself also said, “Which of you will convince Me of sin?” And again He says with reference to Himself, “Behold, the prince of this world comes, and finds nothing in Me.” All which (passages) show that in Him there was no sense of sin; and that the prophet might show more clearly that no sense of sin had ever entered into Him, he says, “Before the boy could have knowledge to call upon father or mother, He turned away from wickedness.”

5. Now, if our having shown above that Christ possessed a rational soul should cause a difficulty to any one, seeing we have frequently proved throughout all our discussions that the nature of souls is capable both of good and evil, the difficulty will be explained in the following way. That the nature, indeed, of His soul was the same as that of all others cannot be doubted, otherwise it could not be called a soul were it not truly one. But since the power of choosing good and evil is within the reach of all, this soul which belonged to Christ elected to love righteousness, so that in proportion to the immensity of its love it clung to it unchangeably and inseparably, so that firmness of purpose, and immensity of affection, and an inextinguishable warmth of love, destroyed all susceptibility (sensum) for alteration and change; and that which formerly depended upon the will was changed by the power of long custom into nature; and so we must believe that there existed in Christ a human and rational soul, without supposing that it had any feeling or possibility of sin.
