1 Corinthians 8:11

So, this weak brother, for whose sake Christ died, becomes [spiritually] destroyed, [and all] because of your "knowledge" [i.e., you know that such eating is harmless, but your weak brother does not know this, so he is led into sin by your unloving example].

Romans 14:15

For if your brother is hurt [spiritually] by [your eating a certain] food, you are no longer acting lovingly [toward him]. Do not destroy [spiritually] the person Christ died for by what you eat.

1 Corinthians 8:13

Therefore, if [eating certain] foods causes my brother to fall away [from God], I will never eat meat again, so I do not cause my brother to fall away.

Do not destroy God's work [i.e., someone's life] for the sake of something to eat. All foods are truly clean [ceremonially]; however, it is wrong for a person to eat something when it causes another person to fall [away from God].

Romans 15:1-3

Now those of us who are strong [spiritually] should put up with [or, help] the failings of [spiritually] weak people, and not [simply] do what pleases ourselves.

1 Corinthians 10:33-1

For even I myself [try] to please everyone in every way, and not to look out [just] for my own good, but [also] for the good of many people, so that they may be saved.
