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 Timothy 4:1-5)
These verse were probably written 5-10 years after Romans and 1 Corinthians. Paul’s teaching on the conscience was well circulated in writing and taught in person throughout his three missionary journeys. This seems to allow him to be very brief with his statements in 1 Timothy. He gave Timothy a warning about false teachers who will come into the church. They will have two false teachings: forbidding marriage and certain foods.
These are familiar conscience issues. Marriage is an issue of the conscience in 1 Corinthians 7 and 9. Food is perhaps Paul’s most commonly used example (Romans 14, 1 Corinthians 8-10) of an issue of conscience. But there are new things to be learned from this short passage.
