Gay and lesbian Episcopalians are celebrating their church’s approval of liturgical rites for blessing same-sex couples. But conservatives are threatening to take “drastic” steps to distance themselves from the Episcopal Church.

Episcopalians meeting at their triennial General Convention in Indianapolis overwhelmingly approved the new rites on July 10. Lay members and priests voted 171–41 in favor of the same-sex blessings. Bishops voted 111–41, with three abstentions.

In doing so, the Episcopal Church joined a small but growing number of religious groups in the U.S. that have sanctioned rites for celebrating same-sex unions. Few, however, are part of international bodies. Episcopalians, on the other hand, form the U.S. branch of the Anglican Communion, a fellowship with 85 million members worldwide and roots in the Church of England. Anxious to keep the communion intact, Anglican leaders have warned the Episcopal Church against adopting pro-gay policies. Many Anglicans in Africa and other parts of the world consider homosexuality sinful.
