New Hampshire Episcopalians elected a priest from Amherst, Mass. as their new bishop Saturday to replace Bishop V. Gene Robinson, the first openly gay bishop in the history of the Anglican Communion, who is scheduled to retire in January. About 200 electors who had gathered at St. Paul’s Church in Concord elected Rev. A. Robert Hirschfeld, rector of Grace Episcopal Church in Amherst. The other two nominees were the Rev. William W. Rich, a senior associate rector at Trinity Church in Boston, a married gay man and the Rev. Penelope Maud Bridges, rector of St. Francis Episcopal Church in Great Falls, Va.
