If I may ask, is the church you attend affiliated with the New Apostolic Reformation? By that I mean those who teach that God has restored the offices of Apostles and Prophets to the church.
I ask because what you said here is exactly what they teach: you have to submit to the absolute authority of the Apostle and the Prophet and those under them. They also teach that the words of the Prophet are authoritative. He receives the word directly from God and imparts it to the congregation or congregations. So they have extrabiblical revelation which is authoritative.
But even if your church isn't one of these, why should a person be expected to submit to someone's authority if their teaching has gone off the rails? Maybe there's a good and legitimate reason you disagree with them. Wouldn't it make more sense to find a group with more sound doctrine.
But it sounds like you're thoroughly committed to the situation you're in so I'll not bother you further. We'll just have to agree to disagree.
Whether apostles have been restored to the church or not I don't know of any, there is no reason in scripture why there may not be apostles ... if apostleship is done away then so is evangelists, teachers and pastors.
However I believe in being subject to the assembly, Paul was most reluctant to judge in the case of the notable sinner at Corinth, he demanded to know why the assembly had not acted. The power to judge is given to the church, the people of God assembled.
If somebody like Paul were to arise and he preached a different gospel or a different doctrine it should be brought to the assembly to judge and let the matter be solved by scripture.
I mean the local assembly, all the problems I see are caused by people in unordained [by scripture] positions of authority at denomination level ... general synods and and councils and general secretariats. Yes certainly by leaders of great para=church organisations.
I don't know the people you name, I'm very fussy about who I will listen to. But these folk are subject to the closest scrutiny of the church and so they should be.
America is the graveyard of once great and powerful ministries, even ministries that have shaken the world but they have gone off into error and the anointing that once attended their ministries is gone agone Paul warned that such a thing could even happen to him.
We have to be alert and vigilant. But like I said, don't throw the baby out with the bath water.
