Colossians 2:21-23

for example, their strict requirements, “You can’t associate with that person!” or, “Don’t eat that!” or, “You can’t touch that!” These are the doctrines of men and corrupt customs that are worthless to help you spiritually. For though they may appear to possess the promise of wisdom in their submission to God through the deprivation of their physical bodies, it is actually nothing more than empty rules rooted in religious rituals!
