Albert Barnes Commentary 1 Corinthians 10:27

"If one of them that believe not biddeth you [to a feast], and ye are disposed to go; whatsoever is set before you, eat, asking no question for conscience` sake." — 1 Corinthians 10:27 (ASV)

If any of them that believe not. This refers to those who are not Christians, who are still pagans.

Bid you to a feast. This is evidently not a feast in an idol's temple but at his own house, if he asks you to partake of his hospitality.

And you be disposed to go. The Greek is, "And you will to go." It is evidently implied here that it would not be improper to go. The Savior accepted such invitations to dine with the Pharisees (see Barnes on Luke 11:37); and Christianity is not designed to abolish the courtesies of social life, or to break the bonds of social interaction, or to make people misanthropes or hermits.

Christianity allows and cultivates, under proper Christian restraints, social interaction that will promote the comfort of people, and especially that which may extend the usefulness of Christians. It does not require, therefore, that we should withdraw from social life or regard the courtesies of society as improper (see Barnes on 1 Corinthians 5:10).

Whatsoever is set before you, etc. This means whether it has been offered in sacrifice or not, for the connection requires us to understand it as such.

Eat. This should be interpreted strictly. The apostle says “eat,” not “drink;” and the principle will not authorize us to drink whatever is set before us, asking no questions for conscience' sake. For while it was a matter of indifference regarding eating whether the meat had been sacrificed to idols or not, it is not a matter of indifference whether a person may drink intoxicating liquor. That is a point on which the conscience should have much to do, and on which its honest decisions and the will of the Lord should be faithfully and honestly regarded.

The word bid means ‘ask.’ For the phrase is set, see Luke 10:7.
