Do any other faiths believe in transubstantiation?

Question:

Answer:

The Eastern non-Catholic Churches, including the Eastern Orthodox, also share the Church’s faith in transubstantiation, though they do not call it that.

Typically Episcopalians do not believe in transubstantiation but in a concept of the Real Presence that would best be termed consubstantiation (though they don’t use this term), since it holds that both Christ and bread and wine are present.
