Because the "Progressives" (as they're called) control the hierarchy, Council of Bishops, and all of the agencies within the denomination, the progressives will KEEP the UMC, called the "Post-Separation United Methodist Church," psUMC. The "traditionalists" will leave and form a new, Wesleyan, traditional denomination which will be the "Global Methodist Church." There's a lot of details and history involved in the coming separation - but I, for one, CAN'T WAIT to be gone from the UMC and join the GMC at its "convening conference." (Date of that is TBD.)
My understanding is even though the GMC has more members, the psUMC will keep the property. Perhaps they will sell some of it back to the UMC. If that is true the quickest breakup is the best because the GMC is subsidizing the psUMC.
As long as the “traditionalists” take women ordination with them, they will end up just the same in a few short years. It is a poison pill.
