Christian and Muslim? Um, no.

An episcopalian woman priest has declared she is Muslim and Christian.
Some parts of the article:

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. Her announcement, first made through a story in her diocese's newspaper, hasn't caused much controversy yet, he said.

The Bishop is okay with it?

As much as she loves her church, she has always challenged it. She calls Christianity the "world religion of privilege." She has never believed in original sin. And for years she struggled with the nature of Jesus' divinity.

More:

Redding's views, even before she embraced Islam, were more interpretive than literal.

She believes the Trinity is an idea about God and cannot be taken literally.

She does not believe Jesus and God are the same, but rather that God is more than Jesus.

She believes Jesus is the son of God insofar as all humans are the children of God, and that Jesus is divine, just as all humans are divine — because God dwells in all humans.

This is really bad theology here and I am only skimming the surface of the problem.
Problems as I see it:
-Mohammad as a prophet continuing revelation.
-The divinity of Christ.
-The nature of the Trinity.
-The Sacraments.
-Etc., etc., etc.

Christianity cannot be "molded" into whatever you want it to be. I don't think the Muslim community will be too happy about it either.
