Galatians 4:5

3. Paul, when writing to the Romans, has explained this very point: “Paul, an apostle of Jesus Christ, predestinated unto the Gospel of God, which He had promised by His prophets in the holy Scriptures, concerning His Son, who was made to Him of the seed of David according to the flesh, who was predestinated the Son of God with power through the Spirit of holiness, by the resurrection from the dead of our Lord Jesus Christ.” And again, writing to the Romans about Israel, he says: “Whose are the fathers, and from whom is Christ according to the flesh, who is God over all, blessed for ever.” And again, in his Epistle to the Galatians, he says: “But when the fulness of time had come, God sent forth His Son, made of a woman, made under the law, to redeem them that were under the law, that we might receive the adoption;” plainly indicating one God, who did by the prophets make promise of the …

As, then, those who have shaken off sleep forthwith become all awake within; or rather, as those who try to remove a film that is over the eyes, do not supply to them from without the light which they do not possess, but removing the obstacle from the eyes, leave the pupil free; thus also we who are baptized, having wiped off the sins which obscure the light of the Divine Spirit, have the eye of the spirit free, unimpeded, and full of light, by which alone we contemplate the Divine, the Holy Spirit flowing down to us from above. This is the eternal adjustment of the vision, which is able to see the eternal light, since like loves like; and that which is holy, loves that from which holiness proceeds, which has appropriately been termed light. “Once ye were darkness, now are ye light in the Lord.” Hence I am of opinion man was called by the ancients φώς . …

“But,” says he, “I speak after the manner of men: when we were children, we were placed in bondage under the elements of the world.” This, however, was not said “after the manner of men.” For there is no figure here, but literal truth. For (with respect to the latter clause of this passage), what child (in the sense, that is, in which the Gentiles are children) is not in bondage to the elements of the world, which he looks up to in the light of a god? With regard, however, to the former clause, there was a figure (as the apostle wrote it); because after he had said, “I speak after the manner of men,” he adds), “Though it be but a man’s covenant, no man disannulleth, or addeth thereto.” For by the figure of the permanency of a human covenant he was defending the divine testament. “To Abraham were the promises made, and to his seed. …

IV. Therefore the prophet brought the virgin from Nazareth, in order that she might give birth at Bethlehem to her salvation-bestowing child, and brought her back again to Nazareth, in order to make manifest to the world the hope of life. Hence it was that the ark of God removed from the inn at Bethlehem, for there He paid to the law that debt of the forty days, due not to justice but to grace, and rested upon the mountains of Sion, and receiving into His pure bosom as upon a lofty throne, and one transcending the nature of man, the Monarch of all, she presented Him there to God the Father, as the joint-partner of His throne and inseparable from His nature, together with that pure and undefiled flesh which he had of her substance assumed. …

14. In these and like testimonies of the divine Scriptures, by free use of which, as I have said, our predecessors exploded such sophistries or errors of the heretics, the unity and equality of the Trinity are intimated to our faith. But because, on account of the incarnation of the Word of God for the working out of our salvation, that the man Christ Jesus might be the Mediator between God and men, many things are so said in the sacred books as to signify, or even most expressly declare, the Father to be greater than the Son; men have erred through a want of careful examination or consideration of the whole tenor of the Scriptures, and have endeavored to transfer those things which are said of Jesus Christ according to the flesh, to that substance of His which was eternal before the incarnation, and is eternal. …

8. For this reason, then, if both the Son and the Holy Spirit are sent thither where they were, we must inquire, how that sending, whether of the Son or of the Holy Spirit, is to be understood; for of the Father alone, we nowhere read that He is sent. Now, of the Son, the apostle writes thus: “But when the fullness of the time was come, God sent forth His Son, made of a woman, made under the law, to redeem them that were under the law.” “He sent,” he says, “His Son, made of a woman.” And by this term, woman, what Catholic does not know that he did not wish to signify the privation of virginity; but, according to a Hebraism, the difference of sex? When, therefore, he says, “God sent His Son, made of a woman,” he sufficiently shows that the Son was “sent” in this very way, in that He was “made of a woman.” Therefore, in that He was born of God, He was in the world; but in that He was born …

51. O Lord our God, we believe in Thee, the Father and the Son and the Holy Spirit. For the Truth would not say, Go, baptize all nations in the name of the Father and of the Son and of the Holy Spirit, unless Thou wast a Trinity. Nor wouldest thou, O Lord God, bid us to be baptized in the name of Him who is not the Lord God. Nor would the divine voice have said, Hear, O Israel, the Lord thy God is one God, unless Thou wert so a Trinity as to be one Lord God. …

6. But as “the Word was made flesh, and dwelt among us,” the same Wisdom which was begotten of God condescended also to be created among men. There is a reference to this in the word, “The Lord created me in the beginning of His ways.” For the beginning of His ways is the Head of the Church, which is Christ endued with human nature ( homine indutus ), by whom it was purposed that there should be given to us a pattern of living, that is, a sure way by which we might reach God. …

Adoption, we know, was familiar to the an cients; for even women adopted the children of other women, as Sarah adopted Ishmael, and Leah her handmaid’s son, and Pharaoh’s daughter Moses. Jacob, too, adopted his grandsons, the children of Joseph. Moreover, the word adoption is of great importance in the system of our faith, as is seen from the apostolic writings. For the Apostle Paul, speaking of the advantages of the Jews, says: "Whose are the adoption, and the glory, and the covenants, and the giving of the law; whose are the fathers, and of whom, according to the flesh, Christ came, who is over all, God blessed for ever." And again: "We ourselves also groan within ourselves, waiting for the adoption of the sons of God, even the redemption of the body." Again, elsewhere: "But in the fullness of time, God sent His Son, made of a woman, made under the law, that we might receive the adopti …

3. As regards the passage from Paul’s epistle which teaches, in opposition to your heresy , that the Son of God was born of the seed of David, it is found in all manuscripts both new and old of all Churches, and in all languages. So the profession which Faustus makes of believing the apostle is hypocritical. Instead of saying, "Assuredly I believe," he should have said, Assuredly I do not believe, as he would have said if he had not wished to deceive people. …

3. "I speak the truth in Christ," says the apostle, "I lie not, my conscience bearing me witness in the Holy Ghost, that I have great heaviness and continual sorrow of heart. For I could wish that myself were accursed from Christ, for my brethren, my kinsmen according to the flesh: who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service and the promises; whose are the fathers, and of whom, as concerning the flesh, Christ came, who is over all, God blessed for ever." Here is the most abundant and express testimony and the most solemn commendation. …

78. Then, as to the statement which follows, “that ye may be the children of your Father which is in heaven,” it is to be understood according to that rule in virtue of which John also says, “He gave them power to become the sons of God.” For one is a Son by nature, who knows nothing at all of sin; but we, by receiving power, are made sons, in as far as we perform those things which are commanded us by Him. And hence the apostolic teaching gives the name of adoption to that by which we are called to an eternal inheritance, that we may be joint-heirs with Christ. …
