That's good to know - I looked at the 'Affirming Catholicism' website which says they
identify and celebrate the positive, inclusive and joyful currents which lie at the heart of the Catholic movement in the Anglican Communion.
So smells, bells, fancy vestments and pilgrimages, probably, but what about the awkward stuff like infallibility and transubstantiation and women priests and, importantly in this context, the Roman Catholic church's clear rejection of transgenderism?
'Quest', which is RC, also has to deal the same awkward RC stuff, and seem to be limited in what they hope to achieve, namely 'walking together':
We looked at our experience as LGBT+ Catholics, of finding ourselves at the margins of the church at times, the call to minister to others who find themselves at the margins and how we “walk together” as a church.
