I mentioned last week that a senior Quaker was invited to speak to the Annual Meeting for Unitarians & Free Christians in Britain. The full text of the address can be accessed here. I think it is a pretty robust explanation, and questioning, of liberal (Christian) religion.
You may also note that, for all their liberalism, 1) British Quakers very much still 'do God', they believe the Divine is at work within their community 2) British Quakers have a strong sense of their history & their continuing mission - they have a shared narrative of which they are each part.
I think Unitarians & Free Christians in Britain have to ask, what's our story?
