Speaking from the Protestant experience, new conditions for reunification have a strange habit of cropping up in microdenominations shortly after the original conditions have been met Look at the UMC - no one I have met seriously argues that different interpretations of LGBT issues, including ordination, is grounds for division of the church. It is predicated upon intolerance for people who disagree AND a belief that those who disagree with you will not tolerate your own views. Most liberals and conservatives in the laity say of the unitive plan: “Yes, they say this would allow us to have gay pastors, but they won’t really let us./Yes, they say they won’t send us gay pastors, but they really will make us have gay pastors.” In general, grounds for church division are theological nonsense predicated upon intolerance of other viewpoints. In most churches, this might make sense. In the Methodist tradition, it makes none. Our very founders disagreed about predestination, about slavery, literally about a civil war (1776), and stayed united.
