1 Timothy 4:1-4

1 But the Spirit says expressly that in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons,  2 through the hypocrisy of men who speak lies, branded in their own conscience as with a hot iron;  3 forbidding marriage and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth.  4 For every creature of God is good, and nothing is to be rejected, if it is received with thanksgiving.
