Just a thinking out loud post: once women bishops get approved for the CofE, why don't FiF and similar simply set up as independent churches with a more-or-less formal link with the CofE itself - rather like the Methodists? Or even a stronger link with Rome? Take the physical churches that they currently occupy, but leave the parish system (other churches can adjust boundaries to cope) and leave behind any church schools and so on. Take pro rata pensions and so on as well. In other words, isn't there a way to do this reasonably and charitably, and avoiding legal arguments over who owns the particular church buildings and so on?
