1 Corinthians 8:4

The Evangelists, too, when they declared that the one Father was “the only true God,” did not omit what concerned our Lord, but wrote: “In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by Him, and without Him was not anything made that was made.” And concerning the incarnation: “The Word,” says [the Scripture], “became flesh, and dwelt among us.” And again: “The book of the generation of Jesus Christ, the son of David, the son of Abraham.” And those very apostles, who said “that there is one God,” said also that “there is one Mediator between God and men.” Nor were they ashamed of the incarnation and the passion. For what says [one]? “The man Christ Jesus, who gave Himself” for the life and salvation of the world.

Such, then, being the case, the Greeks ought by the Law and the Prophets to learn to worship one God only, the only Sovereign; then to be taught by the apostle, “but to us an idol is nothing in the world,” since nothing among created things can be a likeness of God; and further, to be taught that none of those images which they worship can be similitudes: for the race of souls is not in form such as the Greeks fashion their idols. For souls are invisible; not only those that are rational, but those also of the other animals. And their bodies never become parts of the souls themselves, but organs, partly as seats, partly as vehicles, and in other cases possessions in various ways. But it is not possible to copy accurately even the likenesses of the organs; since, were it so, one might model the sun, as it is seen, and take the likeness of the rainbow in colours.

We have, I think, faithfully carried out our plan of showing in how many different ways the sin of idolatry clings to the shows, in respect of their origins, their titles, their equipments, their places of celebration, their arts; and we may hold it as a thing beyond all doubt, that for us who have twice renounced all idols, they are utterly unsuitable. “Not that an idol is anything,” as the apostle says, but that the homage they render is to demons, who are the real occupants of these consecrated images, whether of dead men or (as they think) of gods. On this account, therefore, because they have a common source, for their dead and their deities are one, we abstain from both idolatries. …

Now, when Marcion wholly prohibits all carnal intercourse to the faithful (for we will say nothing about his catechumens), and when he prescribes repudiation of all engagements before marriage, whose teaching does he follow, that of Moses or of Christ? Even Christ, however, when He here commands “the wife not to depart from her husband, or if she depart, to remain unmarried or be reconciled to her husband,” both permitted divorce, which indeed He never absolutely prohibited, and confirmed (the sanctity) of marriage, by first forbidding its dissolution; and, if separation had taken place, by wishing the nuptial bond to be resumed by reconciliation. …

Let us now see on what grounds Celsus urges us to make use of the idol offerings and the public sacrifices in the public feasts. His words are, “If these idols are nothing, what harm will there be in taking part in the feast? On the other hand, if they are demons, it is certain that they too are God’s creatures, and that we must believe in them, sacrifice to them according to the laws, and pray to them that they may be propitious.” In reference to this statement, it would be profitable for us to take up and clearly explain the whole passage of the first Epistle to the Corinthians, in which Paul treats of offerings to idols. …

13. Give good heed to what follows, brethren, “All things were made by Him, and without Him was nothing made,” so as not to imagine that “nothing” is something. For many, wrongly understanding “without Him was nothing made,” are wont to fancy that “nothing” is something. Sin, indeed, was not made by Him; and it is plain that sin is nothing, and men become nothing when they sin. An idol also was not made by the Word; it has indeed a sort of human form, but man himself was made by the Word; for the form of man in an idol was not made by the Word, and it is written, “We know that an idol is nothing.” Therefore these things were not made by the Word; but whatever was made in the natural manner, whatever belongs to the creature, everything that is fixed in the sky, that shines from above, that flies under the heavens, and that moves in universal nature, every creature whatsoever: I will speak …

9. “Confounded be all they that worship carved images” ( ver. 7 ). Hath not this come to pass? Have they not been confounded? Are they not daily confounded? For carved images are images wrought by the hand. Why are all who worship carved images confounded? Because all people have seen His glory. All nations now confess the glory of Christ: let those who worship stones be ashamed. Because those stones were dead, we have found a living Stone; indeed those stones never lived, so that they cannot be called even dead; but our Stone is living, and hath ever lived with the Father, and though He died for us, He revived, and liveth now, and death shall no more have dominion over Him. This glory of His the nations have acknowledged; they leave the temples, they run to the Churches. …

3. But it is asked, If men are called gods to whom the word of the Lord came, are the Angels to be called gods, when the greatest reward which is promised to just and holy men is the being equal to Angels? In the Scriptures I know not whether it can, at least easily, be found, that the Angels are openly called gods; but when it had been said of the Lord God, “He is terrible, above all gods,” he adds, as by way of exposition why he says this, “for the gods of the heathen are devils,” that we might understand what had been expressed in the Hebrew, “the gods of the Gentiles are idols,” meaning rather the devils which dwell in the idols. …

[4.] Ver. 4 . “Concerning therefore the eating of things sacrificed to idols, we know that no idol is anything in the world, and that there is no God but one.” Look what a strait he hath fallen into! For indeed his mind is to prove both; that one ought to abstain from this kind of banquet, and that it hath no power to hurt those who partake of it: things which were not greatly in agreement with each other. For when they were told that they had no harm in them, they would naturally run to them as indifferent things. But when forbidden to touch them, they would suspect, on the contrary, that their having power to do hurt occasioned the prohibition. …

23. There is, therefore, God in God, but not two Gods; for it is written that there is one God, and there is Lord in Lord, but not two Lords, forasmuch as it is likewise written: “Serve not two lords.” And the Law saith: “Hear, O Israel! The Lord thy God is one God;” moreover, in the same Testament it is written: “The Lord rained from the Lord.” The Lord, it is said, sent rain “from the Lord.” So also you may read in Genesis: “And God said, and God made,” and, lower down, “And God made man in the image of God;” yet it was not two gods, but one God, that made [man]. In the one place, then, as in the other, the unity of operation and of name is maintained. For surely, when we read “God of God,” we do not speak of two Gods.

33. Yet what think ye, who deny the goodness and true Godhead of the Son of God, though it is written that there is no God but One? For although there be gods so-called, would you reckon Christ amongst them which are called gods, but are not, seeing that eternity is of His Essence, and that beside Him there is none other that is good and true God, forasmuch as God is in Him; whilst it follows from the very nature of the Father, that after Him there is no other true God, because God is One, neither confounding [the Persons of] the Father and Son, as the Sabellians do, nor, like the Arians, severing the Father and the Son. For the Father and the Son, as Father and Son, are distinct persons, but they admit no division of their Godhead.

45. It is plain, then, that whatsoever is of one substance cannot be severed, even though it be not single, but one. By singleness I mean that which the Greeks call μονοτής . Singleness has to do with a person; unity with a nature. That those things which are of a different substance are wont to be called, not one alone, but many, though already proved on the testimony of the prophet, the Apostle himself has stated in so many words, saying: “For though there be that are called gods, whether in heaven or in earth.” Dost thou see, then, that those who are of different substances, and not of the verity of one nature, are called “gods”? But the Father and the Son, being of one substance, are not two Gods, but “One God, the Father, of Whom are all things, and one Lord Jesus Christ, through Whom are all things.” “One God,” he says, “and one Lord Jesus;” and above: “One God, not two Gods;” and …
