1 Corinthians 10:29

27 If an unbeliever invites you to a meal and you want to go, eat anything set before you without raising questions of conscience.

28 But if someone tells you, “This food was offered to idols,” then do not eat it, for the sake of the one who told you and for the sake of conscience—

the other one’s conscience, I mean, not your own. For why should my freedom be determined by someone else’s conscience?

30 If I partake in the meal with thankfulness, why am I denounced because of that for which I give thanks?

31 So whether you eat or drink or whatever you do, do it all to the glory of God.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
