1 Corinthians 8:10

8:10 For if someone weak sees you who possess knowledge dining in an idol’s temple, will not his conscience be “strengthened” to eat food offered to idols?

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?
