The Rt. Rev. Jeffrey D. Lee, bishop of Chicago and the Rt. Rev. John C. Buchanan, provisional bishop of Quincy, announced that the two dioceses were to reunite on Sunday, September 1.
The conventions of the two dioceses, which had split in 1877 to accommodate growth, had unanimously agreed to the reunion on June 6. The canons of the church require that a majority of bishops and standing committees of elected lay and clergy leaders from other dioceses in the Episcopal Church consent to the reunion. Those consents were received during the summer.
