Catholicism, holiness and spirituality: Discovering ‘Emerging Church’

This is a link from a Catholic fellow and part-n-parcle (is that the right expression) with a comment that Arnold made below. I.E. there seems to be a real penchant for things “Catholic” by “emerging church” (sorry Alan, I don’t like the catch-all either) folk. Don’t have time to post much now, but I would be interested in what you (oh, unsuspecting reader) think. Why do folk who are doing simple/house/organic/emerging/whatever church so draw to things liturgical, Catholic, and ancient. I have a couple ideas that I’ll share later, but any body else have some ideas (and you can’t say “because Robert Webber said so”).
