Romans 14:16
Do not allow what you consider good to be spoken against [i.e., the exercise of a liberty by the strong to eat anything must not become the occasion of criticism by the weak].
Romans 12:17
Do not [try to] pay back a wrong done to you by doing something wrong to the other person. Think about how to live honorably in front of all people.
1 Corinthians 10:29-30
that is, for the sake of the other person's conscience, not your own. For why should my freedom [to eat what I want] be judged [as wrong] by another person's conscience? [Note: The questions in this and the following verse may mean, "it is not worth eating questionable things, if doing so would bring criticism from a weak brother"].
2 Corinthians 8:20-21
[We made this arrangement] to avoid anyone blaming us for the way we handled this generous gift.
1 Thessalonians 5:22
Avoid [the practice of] every kind of evil.
