romans 14:1-6
Do Not Judge Another
Welcome those who are weak in faith, but not for the purpose of quarrelling over opinions. Some believe in eating anything, while the weak eat only vegetables. Those who eat must not despise those who abstain, and those who abstain must not pass judgement on those who eat; for God has welcomed them. Who are you to pass judgement on servants of another? It is before their own lord that they stand or fall. And they will be upheld, for the Lord is able to make them stand.
Some judge one day to be better than another, while others judge all days to be alike. Let all be fully convinced in their own minds. Those who observe the day, observe it in honour of the Lord. Also those who eat, eat in honour of the Lord, since they give thanks to God; while those who abstain, abstain in honour of the Lord and give thanks to God.
Do Not Make Another Stumble
Let us therefore no longer pass judgement on one another, but resolve instead never to put a stumbling-block or hindrance in the way of another. I know and am persuaded in the Lord Jesus that nothing is unclean in itself; but it is unclean for anyone who thinks it unclean. If your brother or sister is being injured by what you eat, you are no longer walking in love. Do not let what you eat cause the ruin of one for whom Christ died. So do not let your good be spoken of as evil. For the kingdom of God is not food and drink but righteousness and peace and joy in the Holy Spirit. The one who thus serves Christ is acceptable to God and has human approval. Let us then pursue what makes for peace and for mutual edification. Do not, for the sake of food, destroy the work of God. Everything is indeed clean, but it is wrong for you to make others fall by what you eat; it is good not to eat meat or drink wine or do anything that makes your brother or sister stumble. The faith that you have, have as your own conviction before God. Blessed are those who have no reason to condemn themselves because of what they approve. But those who have doubts are condemned if they eat, because they do not act from faith; for whatever does not proceed from faith is sin.
