Well, most Anglican priests do, at least
As a cradle Episcopalian, I have yet to meet an Episcopalian Clergyman who believes in Transubstantiation. Although,I have met a few who didn't believe in much of anything, unfortunatly.
There was one in a nearby Parish who went Catholic but he had been a "closet" Catholic for a long time anyway. I never met him personally however.
I intend to move over to the Reformed Episcopal Church myself. The Apostacy in my Church is more than I can stand.
