Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ. Let no one disqualify you, insisting on asceticism and worship of angels, going on in detail about visions, puffed up without reason by his sensuous mind, and not holding fast to the Head, from whom the whole body, nourished and knit together through its joints and ligaments, grows with a growth that is from God.
If with Christ you died to the elemental spirits of the world, why, as if you were still alive in the world, do you submit to regulations—“Do not handle, Do not taste, Do not touch” (referring to things that all perish as they are used)—according to human precepts and teachings? These have indeed an appearance of wisdom in promoting self-made religion and asceticism and severity to the body, but they are of no value in stopping the indulgence of the flesh.
(Colossians 2:16-23 ESV)
Have nothing to do with irreverent, silly myths. Rather train yourself for godliness; for while bodily training is of some value, godliness is of value in every way, as it holds promise for the present life and also for the life to come. The saying is trustworthy and deserving of full acceptance. For to this end we toil and strive, because we have our hope set on the living God, who is the Savior of all people, especially of those who believe.
Command and teach these things. Let no one despise you for your youth, but set the believers an example in speech, in conduct, in love, in faith, in purity. Until I come, devote yourself to the public reading of Scripture, to exhortation, to teaching. Do not neglect the gift you have, which was given you by prophecy when the council of elders laid their hands on you. Practice these things, immerse yourself in them, so that all may see your progress. Keep a close watch on yourself and on the teaching. Persist in this, for by so doing you will save both yourself and your hearers.
(1 Timothy 4:7-16 ESV)
