For if any man see thee which hast knowledge
That is, not any person whatever; not one that has equal knowledge, and can with a good conscience take the same liberty; but one that is weak in the faith, that has not such a clear sight of the doctrine of Christian liberty: if such an one should observe one that is famous for his superior abilities, learning, and knowledge,
sit at meat in the idol's temple;
or at table, or at a feast, where, it seem, after the sacrifice was over, a feast was made of what was left, and friends were invited to partake of it; and some such there were in this church, who to show their Christian liberty, and their knowledge of it, would go and sit down at these feasts publicly, looking upon such meats as having nothing different from common food, or what they bought in the markets, or brought up as their own:
shall not the conscience of him that is weak;
in knowledge, who is not clearly instructed in the doctrine of Christian liberty, but has some doubts upon his mind whether it is lawful to eat such meats, imagining them to be polluted by the idol: "be emboldened"; Greek for "edified"; that is, induced by such an example, and confirmed by such an instance with boldness, and without fear, to eat those things which are offered to idols, contrary to his light, and knowledge, and conscience; and so upon a reflection on what he has done, wound his weak conscience, destroy his peace, and distress his soul. This the apostle proposes to the consideration of these men of knowledge and liberty, as what might be the case, and which they could not well deny, to dissuade them from the use of their liberty, in all places and times, and under all circumstances; all which ought to be seriously weighed and attended to in this business.
