I Timothy 4:2-8

speaking lies in hypocrisy, having their own conscience seared with a hot iron, forbidding to marry, and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth. For every creature of God is good, and nothing is to be refused if it is received with thanksgiving; for it is sanctified by the word of God and prayer. If you instruct the brethren in these things, you will be a good minister of Jesus Christ, nourished in the words of faith and of the good doctrine which you have carefully followed. But reject profane and old wives’ fables, and exercise yourself toward godliness. For bodily exercise profits a little, but godliness is profitable for all things, having promise of the life that now is and of that which is to come.
