These things indeed have a reputation of wisdom in self-imposed worship and humility, and unsparing severity of the body, but are not of any value for the satisfying of the flesh.
Let no one defraud you, delighting in humility and worship of the angels, intruding into things which he has not seen, without a cause being vainly puffed up by his fleshly mind,
Beware lest anyone rob you through philosophy and vain deceit, according to the tradition of men, according to the elements of the world, and not according to Christ.
