1 Timothy 4:1-5

But the Spirit saith expressly, that in later times some shall fall away from the faith, giving heed to seducing spirits and doctrines of demons, through the hypocrisy of men that speak lies, branded in their own conscience as with a hot iron; forbidding to marry, and commanding to abstain from meats, which God created to be received with thanksgiving by them that believe and know the truth. For every creature of God is good, and nothing is to be rejected, if it be received with thanksgiving: for it is sanctified through the word of God and prayer.
