The Baptists for one are still fighting the battles of the past, when a number of their kind (for example in 1806) became Unitarian and the Baptists have never forgiven the Unitarians since. Lancashire had a grouping known as Cookite Methodists, and they became Unitarians, so some Methodists aren't such a happy bunch when it comes to Unitarians. The Church of England, well they had broad Church people who often had contact and empathy with Unitarian theologians, producing similar theological reflections.... (hang on, that means they should mix!).
Padiham is a Christian Unitarian church, so it might be feeling a bit lonely. One of my points when the General Assembly in 2001 adopted the Object that includes the intention to "uphold the liberal Christian tradition" was that this was against the unique pluralist offering Unitarians could give, and anyway it would not impress those like the neighbours at Padiham.
To promote a free and inquiring religion through the worship of God and the celebration of life; the service of humanity and respect for all creation; and the upholding of the liberal Christian tradition.
Folks at the National Unitarian Fellowship - where they have discussions - have been saying how this Object frustrates new converts to Unitarianism, in that what they thought was treating many faiths equally turns out to privilege one. On the other hand those poor souls at the Unitarian Christian Association are thrashing away for an even greater promotion of Christianity amongst the Unitarians and with other ecumenical people. Incidentally, when it came to my friends at The Liberal Rite seeking association with the General Assembly, they were told they were too Christian, by which it must mean that the emergent Liberal Catholicism has been treated as outside the fold by Unitarians.
Good on the Roman Catholics. They feel secure in themselves, obviously. There might even be the odd local Roman Catholic modernist in the area.
Some of the folks at Padiham are more orthodox than many a liberal Anglican, liberal Methodist or, to use the old title, General Baptist. This is a pathetic division and does not reflect denominational realities. I have just enjoyed a reasonably liberal discussion in an Anglican setting.
As for upholding the Trinity, it didn't exist until it was formed doctrinally after the Bible; the Bible does not contain the doctrine. There is only a different late entry of the proto-trinitarian baptismal formula. I know ante-trinitarian worship when I see it, even when accidental.
When I take intercessions at the Anglican Church, I do not pray just for the ecumenical partners of the town. I include Barton Evangelical Church even if they do not include the one I am in - and indeed they shun ecumenical activity. One day I'll give it a visit. Plus I give prayers for people of faith and the leaders who serve them, as well as Christians specifically. Prayers exist in the realms of the gift, not in reciprocal exchange. Prayers are to and with people whoever they are, and without conditions attached. We say and do these for our own good, not because of any transmission that may do something or other we may (arrogantly) regard as harmful or beneficial to the other.
I hope the Unitarians give the Roman Catholics a warm welcome and also invite down people of different faiths. Best wishes to the folks at Padiham.
