1 Corinthians 10:27-29
10:27 If an unbeliever invites you to dinner and you want to go, eat whatever is served without asking questions of conscience.
10:28 But if someone says to you, “This is from a sacrifice,” do not eat, because of the one who told you and because of conscience –
10:29 I do not mean yours but the other person’s. For why is my freedom being judged by another’s conscience?
