There's a concept I've been thinking about, called post-denominational Christianity. First, some definitions:
Denominational Christianity: Here I mean any Christian communion that has a history, a creed and a defining character (it is in some way exclusive). Even groups that may not be denominations under the standard definition, such as Orthodox or Catholics, qualify as part of denominational Christianity under this definition.
Non-denominational Christianity: This was an effort to break away from any denominations and to found a Christian community that did not have any defining character or creed. Very quickly it developed a character and creed. After a couple decades, it also developed a unique history, and therefore itself became a denomination.
Post-denominational Christianity: This is a meta-group within Christianity. Different denominational Christians can be post-denominational. Post-denominational Christianity will not become a denomination, because it will be open to all denominational forms of Christianity, and indeed all groups that identify as Christian. Any worship or doctrinal choice will be a matter of taste, or even a matter of believing that one form of worship or element of doctrine is true or right, while remaining open to the possibility of being wrong. To keep from having a centralised character, post- denominational Christians will worship within multiple denominations; it may be helpful for its diversity that post-denominational Christians attend a different denomination each time they move, or that they go to multiple different churches on Sunday or through the week. The only denominational element post-denominational Christianity will come to have is a historical character.
I am a post-denominational Christian. I worship during the week with a group at my university (non-denominational), p ray the morning prayer at a Scottish Episcopalian Church, and attend contemporary Presbyterian worship on Sundays (while twice a month going to Catholic Mass on Saturday evening). I have made meaningful connections within these communities, and am starting to build bridges.
What do you think of this sort of movement? Does anyone here identify with post-denominational Christianity? What problems do you see with it? What would you think about a post-denominational Christian attending Mass?
A more provocative question... what do you think about opening communion to post-denominational Christians?
