The theologically conservative Pittsburgh diocese voted overwhelmingly today to leave the increasingly liberal Episcopal Church. The breakaway diocese will come under the authority of the Anglican Province of the Southern Cone in South America and will be led Robert Duncan, who had been removed as the diocese’s bishop by the Episcopal Church’s House of Bishops last month.

“The church became as gray as the culture,” said Alison McFarland, one of the lay members who voted for the split. “Undefined Christianity became the problem, and now the church is indistinguishable from the world.”
