Colossians 2:18, 23

Don’t let anyone disqualify you from your prize! Don’t let their pretended sincerity fool you as they deliberately lead you into their initiation of angel worship. For they take pleasure in pretending to be experts of something they know nothing about. Their reasoning is meaningless and comes only from their own opinions.

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!
