1 John 4:15

But, (this doctrine of yours bears a likeness) to the Jewish faith, of which this is the substance, so to believe in One God as to refuse to reckon the Son besides Him, and after the Son the Spirit. Now, what difference would there be between us and them, if there were not this distinction which you are for breaking down ? What need would there be of the gospel, which is the substance of the New Covenant, laying down (as it does) that the Law and the Prophets lasted until John the Baptist , if thenceforward the Father, the Son, and the Spirit are not both believed in as Three, and as making One Only God? God was pleased to renew His covenant with man in such a way as that His Unity might be believed in, after a new manner, through the Son and the Spirit, in order that God might now be known openly, in His proper Names and Persons, who in ancient times was not plainly understood, though d …

If therefore the Jews have been rejected by God, as the faith due to the sacred writings shows, and the Gentiles, as we see, brought in, and freed from the darkness of this present life and from the chains of demons, it follows that no other hope is proposed to man, unless he shall follow true religion and true wisdom, which is in Christ, and he who is ignorant of Him is always estranged from the truth and from God. Nor let the Jews, or philosophers, flatter themselves respecting the Supreme God. He who has not acknowledged the Son has been unable to acknowledge the Father. This is wisdom, and this is the mystery of the Supreme God. God willed that He should be acknowledged and worshipped through Him. …

31. As, then, we call the only Word of God specially by the name of Wisdom, although universally both the Holy Spirit and the Father Himself is wisdom; so the Holy Spirit is specially called by the name of Love, although universally both the Father and the Son are love. But the Word of God, i.e. the only-begotten Son of God, is expressly called the Wisdom of God by the mouth of the apostle, where he says, “Christ the power of God, and the wisdom of God.” But where the Holy Spirit is called Love, is to be found by careful scrutiny of the language of John the apostle, who, after saying, “Beloved, let us love one another, for love is of God,” has gone on to say, “And every one that loveth is born of God, and knoweth God. He that loveth not, knoweth not God; for God is love.” Here, manifestly, he has called that love God, which he said was of God; therefore God of God is love. …

24. We then, by way of giving a rude view of the expressions in this passage, have been led into many words, but blessed John will shew from his Epistle the sense of the words, concisely and much more perfectly than we can. And he will both disprove the interpretation of these irreligious men, and will teach how we become in God and God in us; and how again we become One in Him, and how far the Son differs in nature from us, and will stop the Arians from any longer thinking that they shall be as the Son, lest they hear it said to them, ‘Thou art a man and not God,’ and ‘Stretch not thyself, being poor, beside a rich man.’ John then thus writes; ‘Hereby know we that we dwell in Him and He in us, because He hath given us of His Spirit.’ Therefore because of the grace of the Spirit which has been given to us, in Him we come to be, and He in us; and since it is the Spirit of God, therefore t …

29. It is mere trifling to quote the passage:“Know ye not that your bodies are a temple of the Holy Ghost,” for it is customary in Holy Scripture to speak of a single object as though it were many, and of many as though they were one. And Jovinianus himself should know that even in a temple there are many divisions, the outer and the inner courts, the vestibules, the holy place, and the Holy of Holies. There are also in a temple kitchens, pantries, oil-cellars, and cupboards for the vessels. And so in the temple of our body there are different degrees of merit. God does not dwell in all alike, nor does He impart Himself to all in the same degree. A portion of the spirit of Moses was taken and given to the seventy elders. …
