This is not the first time that people claiming to be following the "Methodist" paradigm have split. Though I'm not up on all of Wesleyan branches, John, Charles, and Samuel at least gave this thing a start by splitting from the Anglican episcopacy, but not going so far as to be congregational in polity like their pal George Whitfield, In America that became Methodistic Episcopalism in the 1700s, from which Methodist Protestants took issue at the rigid clergyism of an episcopacy, 1821; then Wesleyan branch split off in 1841, followed by Southern Methodists (slavery issues) 1844; after that Free Methodists (slavery, rigidity, formalism, etc.) in 1860; and who knows what else.
But all are Arminian in docrine (you can lose your salvation, get it back, lose it again, ad infinitum)--never Calvinistic with its total depravity of the human state.
The coming split off of Hedonistic Methodism is a deeper thing, but still based on how holy one is or can be with a lot of applied effort, or how much values have changed according to man's judgment, depending on what new accommodating Bible version you can find to support a tolerable and constantly shifting degree of depravity.
In the end, it doesn't make any difference. Arminianism is a losing strategy, and can never make anyone holy enough to qualify for citizenship in Heaven.
My hope is that they split in some reasonable way.
My guess is that any new conservative group would reject abortion immediately, but that it would also retain female ordination to elder immediately.
