When the Unitarians and Universalists merged around 1960, both denominations were already considered heretical by most Christians -- the former because they denied the Trinity, the latter because they believed in Universal Reconciliation (UR) -- the notion that all will eventually be saved, therefore, there is no hell (or at least no eternal hell). The in-joke was that one group thought god was too good to condemn man and the other thought man was too good for god to condemn.

Their post-Christian position now is that they are non-creedal (do not subscribe to the historic Christian creeds), rather, they are "covenantal", meaning they have a general concept of loving and taking care of one another and your fellow man, or as their slogan has it, "standing on the side of love". They accept believers in any religion or unbelievers.

I don't know how far the Quakers have gone in this regard -- probably not quite there yet at least on paper -- but I think if you're really going to reject saying anything specific about god, theology or doctrine, then you have to abandon creedalism and base the community on something else.

Sadly in my experience, the UUs are still cliquish and weird, just around politics rather than theology. Even though I'm pretty liberal, the local congregation has a lot of members doing civil disobedience-level activism, practicing veganism, etc, and pretty much looking down their snoots at those who don't do these things. Many members are less extreme but you know how it is in any organization -- a few people have an outsize impact in terms of emotion and decibel levels and stridency. Mostly I just subscribe to their listserv and I often can't stand to read the interactions on there -- too many ass-kicking contests.

So I wish the Quakers well and hope they can maintain a good sense of community without the unctuous lemmings taking over.

I was not aware that Quakers are particularly into drugs or hiking. Is that an actual thing?
