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.
Romans 16:18
For such men are not serving our Lord Christ but their own [unspiritual] appetites. They are deceiving the minds of innocent people by their smooth talk and flattering words.
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].
1 Peter 5:2
You should serve as shepherds of God's flock [i.e., the church], among whom you minister, providing careful oversight [of the people], not because you feel forced to, but because you want to, as this is in accordance with the way God wants it to be. Do not [serve as elders] simply out of a desire for the income you receive, but because your heart is in it.
2 Peter 2:2-3
And many people will follow their unrestrained, indecent conduct, which will result in the true way [of God] being spoken against.
