ARCIC document about the place of the Blessed Virgin in theology and devotion has been much touted lately, and I think for good reason. (For two interesting takes on it, try J-Tron and the Young Fogey.) I think, however, that it is a bit overzealous to identify many commonalities between Roman Catholic devotional practice and the devotional practice of Episcopalians. This is mainly because, in my experience, Episcoplians really don't have much of a devotional life. If there were a quantifiable average, I would wager it would be somewhere rather below that of the Roman Catholic. Episcopalians are encouraged to think that anything whatsoever counts as devotion, so long as you feel spiritual about it. Some examples (that I have actually heard) are: fishing, yoga, walking labyrinths, gay sex, communing with nature, and being quiet.
Fr. Kimel's analysis of the authority issue in ECUSA is spot-on, in this instance. There is no real Episcopal devotional practice. Insofar as there might be said to be an Episcopal teaching on devotional practices, it is probabably something like "whatever floats your boat."
Now, this attitude isn't always bad. Its the permissive element of Episcopalian authority that permits me to continue as not-a-Calvinist and not-an-insane-person --- that is, against the grain of ECUSA's past and current cultural vagaries. But when people begin to speak of "the devotional practice" of the ECUSA (or even of "theology" for that matter), I think they are more or less kidding themselves.
I'm still pleased with the ARCIC statement.
