Deuteronomy 21:18 If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and [that], when they have chastened him, will not hearken unto them:
21:19 Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place;
21:20 And they shall say unto the elders of his city, This our son [is] stubborn and rebellious [against God], he will not obey our voice; [he is] a glutton, and a drunkard.

Proverbs 8:13 The fear of the "I AM" [is] to hate evil: pride, and arrogancy, and the evil way, and the perverse mouth, do I hate.

3:3 Forbidding to marry, [and commanding] to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know The Truth.
3:4 For every creature of God [is] good, and nothing to be refused, if it be received with thanksgiving:
You were given God's Law to keep you healthy and and the environment pristine.
