THE EPISCOPAL CHURCH’S ELECTION of its first female presiding bishop has made a split with the Anglican Communion even more likely. Katharine Jefferts Schori delighted Episcopalians who support gay bishops, same-sex unions, and other liberal social policies. But her victory also confirmed what church conservatives have long feared: The liberal majority is going to keep pushing until the leftward drift of the past few decades is complete.

Jefferts Schori embodies the Episcopal evolution. While bishop of Nevada, she voted for a gay bishop’s consecration and allowed same-sex blessings. She was also noted for her political activism. In letters to Nevada politicians, she quoted Scripture and used the power of her office to lobby for liberal policies.
