Call it what you like. The fact of the matter is that you do not discuss. You lecture never allowing for the possibility that you and/or your church may be error. Until you admit that possibility, you cannot grow. Until you are able to grow you are likely to stagnate.You seem to want to end the conversation - NOT because there is no "edification" - but because you got caught with your historical pants down.
Again - don't make these kinds of false claims about history unless you can back them up - with HISTORY.
