Doctrine of Demons: Don't Eat That Food!

1 Timothy 4:1-5 teaches us that when religious teachers tell us not to eat certain foods (to obtain some sort of purity), such teaching is not harmless. Paul calls this a doctrine of demons and says that some, by listening to such teaching, have wandered away from the faith. Yet today we have popular "Christian" teachers on Christian radio -- teachers like Jordan Rubin and Don Colbert -- who utter just such commands and use the Bible to support their recommendations for such abstinence. We do not seem to understand the danger of listening to such teachers.
