Romans 14:14-18

14I know and am convinced by the Lord Jesus that there is nothing unclean of itself; but to him who considers anything to be unclean, to him it is unclean.

15Yet if your brother is grieved because of your food, you are no longer walking in love. Do not destroy with your food the one for whom Christ died.

16Therefore do not let your good be spoken of as evil;

17for the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit.

18For he who serves Christ in these things is acceptable to God and approved by men.
