Unless the NE Bishop is denounced, defrocked, and expelled, yes it it lost. Because if they tolerate this apostate, they tolerate all apostasy. Which pretty much describes my experience with the UMC when I was kicked out for requesting greater Biblical orthodoxy and less leftist politics from the pulpit. There may be sound congregations and perhaps even solid conferences, but as long as they countenance heresy, yes it is lost.
While that may happen, it won't happen quickly.
