So do not let what you regard as good be spoken of as evil.
Romans 14:16 ESV

The "good" isn't your liberty to eat whatever you want, but your table fellowship with your brother and the Kingdom of God and the righteousness and peace and joy mentioned in the next verse, not whatever you believe about meat or diet or any man-made religious traditions. "Don't destroy him for whom Christ died. Don't therefore make your dining together into a cause for him to speak evil of you and that Kingdom."
