Are you saying that you wouldn't label snake-handling in services as an odd doctrine? Or "Jesus only" doctrine? Or Christian Science's "mind over matter" doctrine? I'm not hesitant to call those ideas odd, if not worse (heretical). I hope you don't actually "come around" all the way to transubstantiation. This doctrine causes its adherents to bow down in homage to a man-made wafer as Almighty God; if this were pleasing to God, He would have had no problem with the golden calf. The idea of physically eating the actual human flesh and blood of the pre-incarnate Jesus is a concept I now find repulsive, as well as pointless (new birth is a spiritual change, and we feed on Christ spiritually, so nothing spiritual can be gained from a physical ingestion of Almighty God even were it possible to do so).
