1 Timothy 4:1-5 RSV

1 Now the Spirit expressly says that in later times some will depart from the faith by giving heed to deceitful spirits and doctrines of demons,
2 through the pretensions of liars whose consciences are seared,
3 who forbid marriage and enjoin abstinence from foods which God created to be received with thanksgiving 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 thanksgiving;
5 for then it is consecrated by the word of God and prayer.
