But there is not in every man that knowledge: for some with conscience about the idol unto this hour eat it as a thing offered unto an idol; and their conscience being weak is defiled.
All Commentaries on 1 Corinthians 8:7 Go To 1 Corinthians 8
Cornelius a Lapide
AD 1637
Howbeit there is not in every man that knowledge. I.e, that an idol and what is offered to it are nothing.
For some with conscience of the idol unto this hour eat it as a thing offered unto an idol. They eat what is offered to an idol with reverence, thinking that the idol has something that is Divine, and that the offering was made to the deity lurking behind the idol. So Amselm.
Theophylact explains this verse differently, thus: "Some eat of what has been offered to the idol, under the false supposition that it has been changed by the idol and physically breathed upon by a devil, and so in some way affected by him, or, at all events, morally defiled by him, so as to be regarded to be now his property and food, with power to change and pollute him that eateth of it. In this way they eat of idol sacrifices under the mistaken belief that they are polluted by them." This sense also is suitable and likely; for there can be no doubt that, among the Corinthians lately converted, were some who were over-scrupulous and some over-superstitious.
And their conscience being weak is defiled. Being not fully instructed in the faith about these matters, they go against their conscience in following the example of others, and eating of idol sacrifices. So Chrysostom.
Libertines do but rave when they lay down from this passage that neither fornication, nor drunkenness, nor anything else is sin, if the conscience has no scruples. This is to advise men to get rid of conscience, so as to sin at pleasure. Libertines therefore have no conscience; and they would appear therefore to have put aside their manhood, their reason, and all virtue. But what folly is it to ascribe such sentiments to the Apostle! For who is there that sees not that the Apostle is here speaking, not of sins or of forbidden things, but of things indifferent, such as the eating of idol offerings?
