The short version if you can’t take 18 minutes of Bob Jones:
1 Timothy 4:1-5 (NASB)
1 But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons,
2 by means of the hypocrisy of liars seared in their own conscience as with a branding iron,
3 men who forbid marriage and advocate abstaining from foods which God has created to be gratefully shared in by those who believe and know the truth.
4 For everything created by God is good, and nothing is to be rejected if it is received with gratitude;
5 for it is sanctified by means of the word of God and prayer.
