I may not be correct in this, but I always thought a heresy is something you excommunicate people for...

Lets say, he was an A-mill. before he became confused (very confused). If he held some ministry position w/ in congregation (music, sunday school, secretary, etc, etc) what action would you suppose be correct to take? Would you remove him from ministry? Would you advise him to refrain from the Lord's Supper?

(dont get this the wrong way, to me it seems to be a very complicated issue...)
