4. Concerning, therefore, the eating of those things He now returns to the statement with which he had set out, and speaks more plainly in reference to the pretext made use of by the Corinthians. For as the whole of the evil took its rise from this root — that they were pleased with themselves, and despised others, he condemns, in general, that contemptuous knowledge which is not seasoned with love. Now, however, he explains particularly, what is the kind of knowledge on which they valued themselves — that an idol is an empty figment of the human brain, and must therefore be reckoned as nothing; and accordingly, that the consecration, that is gone through in name of the idol, is a foolish imagination, and of no importance, and that a Christian man, therefore, is not polluted, who, without reverence for the idol, eats of things offered to idols. This is the sum of the excuse, and it is not set aside by Paul as false, (for it contains excellent doctrine,) but because they abused it, in opposition to love
As to the words, Erasmus reads thus — “An idol has no existence.” I prefer the rendering of the old translation — An idol is nothing. For the argument is this — that an idol is nothing, inasmuch as there is but one God; for it follows admirably — “If there is no other God besides our God, then an idol is an empty dream, and mere vanity.” When he says — and there is none other God but one, I understand the conjunction and as meaning because. For the reason why an idol is nothing is, that it must be estimated according to the thing that it represents. Now it is appointed for the purpose of representing God: nay more, for the purpose of representing false gods, inasmuch as there is but one God, who is invisible and incomprehensible. The reason, too, must be carefully observed — An idol is nothing because there is no God but one; for he is the invisible God, and cannot be represented by a visible sign, so as to be worshipped through means of it. Whether, therefore, idols are erected to represent the true God, or false gods, it is in all cases a perverse contrivance. Hence Habakkuk calls idols teachers of lies, (Habakkuk 2:18,) because they deal falsely in pretending to give a figure or image of God, and deceive men under a false title. Hence οὐδεν (nothing) refers not to essence, but to quality — for an idol is made of some substance — either silver, or wood, or stone; but as God does not choose to be represented in this way, it is vanity and nothing as to meaning and use.
