If any of those who do not believe invites you to dinner, and you desire to go, eat whatever is set before you, asking no question for conscience’ sake.  But if anyone says to you, “This was offered to idols,” do not eat it for the sake of the one who told you, and for conscience’ sake; for “the earth is the Lord’s, and all its fullness.”  “Conscience,” I say, not your own, but that of the other.

For why is my liberty judged by another man’s conscience?

1 Corinthians 10:27-29
