The problem is that if I substituted “purpose driven doctrine” with “rejection of homosexuality doctrine in the Episcopal church”, then I would advise similar methods of dealing with dissent to any Episcopal pastor who wanted to try to salvage his church. If there is heresy in the “purpose driven” doctrine, it’s not necessarily in THIS part of it.
As a Christian, you have the right and responsibility to address BOTH in the church. The pastors should not be gestapo agents stalking folks to the next church that dared to object to the changes in their own church and telling future pastors not to allow them into any leadership role. If the church member had truly done something unbiblical and was unrepentant, perhaps. But, NOTHING in Scripture indicates we should give pastors carte blanche permission to do or say whatever they want. Paul commended the Bereans for checking his words with Scripture. False prophets are there. When the flock is being scattered because of PD methodology (as well as theology), then those who are discerning should take a stand.
