Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons, through the insincerity of liars whose consciences are seared, who forbid marriage and require abstinence from foods that God created to be received with thanksgiving by those who believe and know the truth. For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, for it is made holy by the word of God and prayer. —1 Tim 4:1-5 (ESV)
This is a direct indictment of the modern church. The modern “Christian” teaching of abstinence, rather than marriage, combined with it’s continued push to delay marriage through endless and wearying education, empty careerism, and all the other things that are pushed as necessary to make one “ready” for marriage adds up to a prohibition. We can also see the tendency to to proscribe foods–if you have ever talked to a Christian teetolitarian*, you know what I mean, but the tendency goes well beyond that, as Empath likes to point out.
Beware the doctrines of demons.
*Teetolitarian, n. One who believes everyone ought to be compelled by the church, the government, or both to abstain from all alcoholic beverages, often launching into lectures to that effect upon even observing the presence of such beverages in homes where they are a guest.
