First, two newspaper columns commenting on recent ECUSA events:
When the Archbishop Calls by Colbert King in the Washington Post.
A Divided Episcopal Church? by Peter Steinfels in the New York Times.
Second, here is a pastoral letter written by the Bishop of Arizona to his diocese. (Arizona is a diocese which voted in all three orders in favour of the confirmation of the Bishop-elect of New Hampshire and in favour of the compromise resolution on same-sex blessings.)
I found all of these helpful in understanding how mainstream Americans view recent ECUSA events.
