But the Apostle writes a rule not for one case, but for all. In all cases it could happen that sometimes a weak Christian says this, and sometimes a pagan. Therefore let us suppose that either a weak Christian or a tempting pagan says, "This has been offered to idols."
Do not eat, says the Apostle. Do not eat for the sake of the one who disclosed it, that is, sparing him.
It is clear how the weak Christian is spared. If the strong man, after being informed, were to eat, the weak man could no longer refuse to eat. Having begun to eat, he would eat it as something religiously significant, and would thereby defile his conscience.
But if the strong man refuses to eat, he will give the weak man courage to abstain also, and thus will save him from the staining of his conscience.
But in what way is the pagan spared? If a pagan says this to a Christian, he plainly says it with the thought that the Christian ought not to eat it. Such is the form taken by his pagan conscience.
If the Christian nevertheless began to eat, the pagan might think: what is this? Christians boast of the loftiness of their faith and moral teaching, yet show them only a tasty morsel, and they are ready to live again at peace with our gods.
For him, what has been offered to idols is something sacred. In some manuscripts it stands as ιεροθυτον. Eating of it, in his view, anoints a person with the blessing of the gods. The same, in his thinking, will pass to the Christian.
How is this, he will think? From an unfavorable thought about the Christian, he will pass to an unfavorable thought about Christianity.
Consequently, to eat after such a notice will mean degrading oneself as a Christian. It will mean degrading all Christians in one's own person, and degrading Christianity itself.
Therefore one's dignity as a Christian, the honor of Christians, and the honor of Christianity itself require that one not taste such food once it is said to have been offered to idols.
This must be done for the sake of the one who disclosed it, for the sake of others like him, and for the sake of the disclosure itself.
With what thought should this be done? To show contempt for everything connected with idol service. Not because what has been offered to idols is anything, but because, insofar as it belongs to idol service, it is abominable.
Out of contempt for idol service, I also despise this thing offered to idols. Thus Chrysostom says: "The Apostle commands abstinence from idol sacrifices, not as though they possessed power, but as things worthy of abhorrence.
"Avoid what has been offered to idols, he says, not because it can cause harm. It has no power whatever. Avoid it because it is contemptible.
"Nevertheless, on the ground that it has no power, do not eat it indifferently. It is the table of enemies and of the impious."
Thus this abstinence before the pagans will be an instructive preaching about the dignity of Christianity and the contemptible character of idol service.
"For the sake of the one who disclosed it" will mean, in this case, so as not to close to him the door of ascent to clear knowledge of the height of Christianity, and thereby the door of faith.
For eating would confuse all his concepts and darken the radiant countenance of the faith of Christ.
And conscience. Whose conscience? The Apostle explains below: not one's own conscience, but another's. In the two preceding cases (1 Cor 10:25, 27), one's own conscience was meant. Here, another's is meant.
Whose, then? Most directly, the conscience of the one who disclosed it. Whether a pagan says, "This has been offered to idols," or a weak Christian says it, not eating this idol-offering will be healing for the conscience of both.
"For the earth is the Lord's, and the fullness thereof." This must be connected with the course of the discourse in this way: I mean not your conscience, but another's.
For your conscience, the conviction remains unchanged that in the Kingdom of the Lord all is good, and nothing is to be rejected.
"I do not forbid it," he says, "as though it were something alien, for the earth is the Lord's, but on account of conscience, that is, lest harm be done.
"Then should one investigate? No, he says. I mean not your conscience, but another's, for I have already said, 'for the sake of the one who disclosed it'" (Chrysostom).
