The Lead at Episcopal Cafe has the scoop:
The Episcopal Church's House of Bishops has deposed Bishop Robert Duncan of Pittsburgh for abandonment of communion. Eighty-eight bishops voted in favor of deposing Duncan, 35 voted against and four abstained according to several sources in the House of Bishops.
Two statements from the Diocese, which was clearly expecting this outcome, are here and here. Note that Geoff Chapman, author of the Chapman Memo is a member of the Standing Committee. The statement is not unanimous. The Rev. James Simons, who opposes secession, did not sign. Geoff Chapman, as you may recall was the author of the "Chapman Memo" which put forth a plan by which a group of conservative Episcopalians intended to gain control of the assets of the Episcopal Church.
You can read the rest here and also find links to related statements by the group Progressive Episcopalians of Pittsburgh as well as the actual document of the deposing of this alleged bishop.
This comes as the Diocese of Pittsburgh is preparing to meet in convention on October 4th.
