Check out this post on The Scriptorium Daily about a priest named Ann Holmes Redding in the Episcopalian Church USA. She says she is both a Christian and a Muslim. The post by Greg Peters quotes her as saying, “I am both Muslim and Christian, just like I’m both an American of African descent and a woman. I’m 100 percent both."
That's bad enough, but what's even more amazing is that Redding's bishop is quite OK with a priest in the Episcopal church being both a Christian and a Muslim. According to the Seattle Times, “Redding’s bishop, the Rt. Rev. Vincent Warner, says he accepts Redding as an Episcopal priest and a Muslim, and that he finds the interfaith possibilities exciting.”
In Pilgrim's Progress, the classic book by John Bunyan, there is mentioned a character named Mr. Facing Both Ways. Ms. Redding is like Mr. Facing Both Ways. She's an example of someone who wavers between two mutually exclusive opinions (1 Kings 18:21). A person cannot believe in Jesus, who claimed to be the one way to God, and at the same time adopt the Muslim faith.
But then such "interfaith absurdity" (as Peters calls it) should not surprise us, for in our day truth has been trumped by tolerance, and theology by ecumenism.
