1 Corinthians 8:7
But all believers do not recognize these facts. Some, from force of habit in relation to the idol, even now eat idol sacrifices as such, and their consciences, being but weak, are polluted.
Romans 14:14
As one who lives in union with the Lord Jesus, I know and am certain that in its own nature no food is 'impure'; but if people regard any food as impure, to them it is.
1 Corinthians 8:9-10
But take care lest this liberty of yours should prove a hindrance to the progress of weak believers.
1 Corinthians 10:28-29
But if any one tells you, "This food has been offered in sacrifice;" abstain from eating it--out of respect for him who warned you, and, as before, for conscience' sake.
Romans 14:22-23
As for you and your faith, keep your faith to yourself in the presence of God. The man is to be congratulated who does not pronounce judgement on himself in what his actions sanction.
1 Corinthians 1:10-11
Now I entreat you, brethren, in the name of our Lord Jesus Christ, to cultivate a spirit of harmony--all of you--and that there be no divisions among you, but rather a perfect union through your having one mind and one judgement.
