Father Richard asked if I've got a read on the "emergent Mary." For that, I might check out Scot McKnight's book, The Real Mary (you can pick it up at Joseph Beth Booksellers in Lexington, or order it from Bill Bean), but I've not read it myself. He seems to be the go-to guy for evangelical/emergent Christians on Our Lady at the moment. Go to his blog, Jesus Creed, and click the Mary category and go back to the archives in June. I know he's written also about prayers to the saints and moreover, the Communion of Saints, but I don't know about praying to Mary. I know Alan's written about it, and maybe he'll be good enough to post a link for us.
I haven't spent much time with the Marian Dogmas myself. I have no problem with some kind of mystical role for the Theotokos, but I think almost anything along those lines goes beyond scripture. You all realize that I don't have a problem with that as such, but I like to tread cautiously when we do that.
I'll just say that like a good proto-Anglo-Catholic (?), I find Our Lady much less threatening than does the average southern Protestant. Ha!
