Colossians 2:16
Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]:
 
 
1 Timothy 4:1-4
Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; Speaking lies in hypocrisy; having their conscience seared with a hot iron; 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. For every creature of God [is] good, and nothing to be refused, if it be received with thanksgiving: For it is sanctified by the word of God and prayer.
