What does it mean to be orthodox? Who decides who is a heretic and who is a faithful true follower? Rick Henderson and Mike Bell dig into the difference between heresy and orthodoxy, teachings that amount to aberrant theology and teachings that are simply misunderstandings, and they start with speaking in tongues -- from a Biblical perspective but also from modern claims. Can you be wrong without necessarily being a heretic? Certainly the wrong teaching can still do damage, so where's the line?
