Do you know how MANY people have tried to get private meetings with him for this very idea?
Also, this is not a personal offense that is to be kept private. False teaching is to be rebuked/correctly publicly because it has been done publicly. Those who have heard it also need to hear the correction. It cannot be kept private.
Sorry .. I don't agree with you.
NO ONE HAS THE AUTHORITY TO PUBLICALLY URSURP THE AUTHORITY OF THEIR PASTOR IN PUBLIC - NOBODY! God never set the church up that way .. and when people go public with their petty greivances .. they only harm themselves.
There are many ways to contact your pastor .. many! But .. unless you are in leadership within that church .. you have no God-given authority to confront your pastor.
Don't like those rules .. start your own church.
