Red lights to warn you of false teachers

Dan Phillips:
It occurred to me that many might be served if we offered warning-signs of (at worst) false or (at best) unreliable teachers. Here are a number of such indicators. Some are instantly obvious; others only over the passage of time (1 Tim. 5:24).

Any one of these should signal alarm. Found all together in the same person, trainwreck is assured.

Pyromaniacs: Red lights.
