"I am both Muslim and Christian":

So said the Rev. Ann Holmes, an Episcopal priest. As an outsider to both faiths, this really doesn't bother me. But there may well be some doctrinal issues that have to be worked out.

This whole affair reminds me of what Ben Franklin once said, which illustrates the interesting context of a unitarian (Franklin) supporting Trinitarian churches (which he did). Here Franklin describes the "purpose" of the church that he helped see built:

Both house and ground were vested in trustees, expressly for the use of any preacher of any religious persuasion who might desire to say something to the people at Philadelphia; the design in building not being to accommodate any particular sect, but the inhabitants in general; so that even if the Mufti of Constantinople were to send a missionary to preach Mohammedanism to us, he would find a pulpit at his service.
