Oh yes, the Methodists should go ahead as Episcopalian Robinson said and have a MAJOR Denominational Split and loose a huge percentage as they did to the Anglicans.
Oh Yeah, right, go right ahead and drink the Koolaid and watch another denomination vanish on the ash-heap of history.
The real problem with Robinson's approach is he doesn't have any idea of how God views sin and how desperate mankind's situation really is. If he did, he would abhor anything that had any taint of sin and promoting Holy Matrimony (one man to one woman under God) as fast as he possibly could.
But adultery (mixing crud with Holy Matrimony) is in vogue these days and Robinson cannot help but preach it.
