Romans 14:14-18

I know and am convinced [as one] in the Lord Jesus that nothing is unclean [ritually defiled, and unholy] in itself; but [nonetheless] it is unclean to anyone who thinks it is unclean. If your brother is being hurt or offended because of food [that you insist on eating], you are no longer walking in love [toward him]. Do not let what you eat destroy and spiritually harm one for whom Christ died. Therefore do not let what is a good thing for you [because of your freedom to choose] be spoken of as evil [by someone else]; for the kingdom of God is not a matter of eating and drinking [what one likes], but of righteousness and peace and joy in the Holy Spirit. For the one who serves Christ in this way [recognizing that food choice is secondary] is acceptable to God and is approved by men.
