8 Now concerning things sacrificed to idols: We know that we all have knowledge. Knowledge puffs up, but love builds up. 2 But if anyone thinks that he knows anything, he doesn’t yet know as he ought to know. 3 But anyone who loves God is known by him.
4 Therefore concerning the eating of things sacrificed to idols, we know that no idol is anything in the world, and that there is no other God but one. 5 For though there are things that are called “gods”, whether in the heavens or on earth—as there are many “gods” and many “lords”— 6 yet to us there is one God, the Father, of whom are all things, and we for him; and one Lord, Jesus Christ, through whom are all things, and we live through him.
St. Irenaeus: On the Apostolic Preaching
For it is necessary that, things that are made should have the beginning of their making from some great cause; and the beginning of all things is God. For He Himself was not made by any, and by Him all things were made. And therefore it is right first of all to believe that there is One God, the Father, who made and fashioned all things, and made what was not that it should be, and who, containing all things, alone is uncontained. Now among all things is this world of ours, and in the world is man: so then this world also was formed by God.
5. Thus then there is shown forth One God, the Father, not made, invisible, creator of all things; above whom there is no other God, and after whom there is no other God. And, since God is rational, therefore by (the) Word He created the things that were made; and God is Spirit, and by (the) Spirit He adorned all things: as also the prophet says: By the word of the Lord were the heavens established, and by his spirit all their power. Since then the Word establishes, that is to say, gives body and grants the reality of being, and the Spirit gives order and form to the diversity of the powers; rightly and fittingly is the Word called the Son, and the Spirit the Wisdom of God. Well also does Paul His apostle say: One God, the Father, who is over all and through all and in its all. For over all is the Father; and through all is the Son, for through Him all things were made by the Father; and in us all is the Spirit, who cries Abba Father, and fashions man into the likeness of God. Now the Spirit shows forth the Word, and therefore the prophets announced the Son of God; and the Word utters the Spirit, and therefore is Himself the announcer of the prophets, and leads and draws man to the Father.
This then is the order of the rule of our faith, and the foundation of the building, and the stability of our conversation: God, the Father, not made, not material, invisible; one God, the creator of all things: this is the first point of our faith. The second point is: The Word of God, Son of God, Christ Jesus our Lord, who was manifested to the prophets according to the form of their prophesying and according to the method of the dispensation of the Father: through whom all things were made; who also at the end of the times, to complete and gather up all things, was made man among men, visible and tangible, in order to abolish death and show forth life and produce a community of union between God and man. And the third point is: The Holy Spirit, through whom the prophets prophesied, and the fathers learned the things of God, and the righteous were led forth into the way of righteousness; and who in the end of the times was poured out in a new way a upon mankind in all the earth, renewing man unto God.
And for this reason the baptism of our 76regeneration proceeds through these three points: God the Father bestowing on us regeneration through His Son by the Holy Spirit. For as many as carry (in them) the Spirit of God are led to the Word, that is to the Son; and the Son brings them to the Father; and the Father causes them to possess incorruption. Without the Spirit it is not possible to behold the Word of God, nor without the Son can any draw near to the Father for the knowledge of the Father is the Son, and the knowledge of the Son of God is through the Holy Spirit; and, according to the good pleasure of the Father, the Son ministers and dispenses the Spirit to whomsoever the Father wills and as He wills.
7 However, that knowledge isn’t in all men. But some, with consciousness of an idol until now, eat as of a thing sacrificed to an idol, and their conscience, being weak, is defiled. 8 But food will not commend us to God. For neither, if we don’t eat are we the worse, nor if we eat are we the better. 9 But be careful that by no means does this liberty of yours become a stumbling block to the weak. 10 For if a man sees you who have knowledge sitting in an idol’s temple, won’t his conscience, if he is weak, be emboldened to eat things sacrificed to idols? 11 And through your knowledge, he who is weak perishes, the brother for whose sake Christ died. 12 Thus, sinning against the brothers, and wounding their conscience when it is weak, you sin against Christ. 13 Therefore, if food causes my brother to stumble, I will eat no meat forever more, that I don’t cause my brother to stumble.
