What’s the downside? It’s not like the Church is going to come out afterwards and say “How about that? We ARE going to ordain women…”
If the focus is on identifying the common ground we DO hold, surely reasonable people will notice that, over the years, that list is shrinking as more and more bizarre ideas become “mainstream” in Anglicanism. IMO, that can’t help but be good both in as a check in the decay of Anglicanism and a beacon for those who become discouraged and want out.
