To clarify the previous post (found here: Most of the conversation about the Bble is in the comments.
I say that "post-denominationalism" applies to the social trend in which Orthodox Christians don't pay much attention to denominational labels any more. (Lutheran, Methodist,etc). When it comes to what is taught in a Christian Church, they are interested in whether the church is "Bible Believing" or "Bible Interpreting". I say that UUism, even our Christian wing, lies outside of this social trend, because we are not an Orthodox, creedal church.
. Almost all UU's are Bible Interpreters. (There are a few UU's who insist on taking the Bible literally and rejecting it.) While we don't have a creed, we do have practices. In a few of our churches, the practice is to focus on the Bible. In some the practice is to include the Bible. In some, especially lay-led congregations, the practice is to ignore or reject the Bible. Ministers who serve the Biblically focused churches are mostly in the New England Parish system, which is, after all, pre-denominational. However it is still covenant rather than creed which determines church membership and if I were serving such a church, I would shout that to the rafters, because it is a point that is important to younger generations. I would also broaden the focus, beginning with the Biblical text but bringing in other faiths, philosophies and scriptures, because that is also attractive. Also, I'd preach and preach and preach the good news of Universalism!
Finally, I believe we should claim our UU'ism and celebrate its heritage but not make it the focus of our life together, especially with newcomers. The worship of chalices, principles, assemblies and famous people is unseemly.
