I say good for them.
Someone forgot to send you the memo about the proper Orthodoxical response. Anything to do with Anglicans/Episcopalians is bad. If they do something bad then it's bad and should be treated with disgusted condescension. If they do something good then it's just a delay or mistake that will be made bad in due time.
The proposal failed because it did not receive two/thirds vote in each of its three separate "houses", not because it was not supported by a healthy majority. Here were the votes:
House of Bishops: 44 for/3 against or 94% for women bishops.
House of Clergy: 148 for/45 against or 77% for women bishops.
House of Laity: 132 for/74 against (just six votes short of two thirds) or 64% for women bishops.
Overall, the combined votes amounted to 324 for (or 73%) and 122 against (or 27%).
Delaying the inevitable, indeed.
