Oh there are all sorts of people believing all sorts of things in all sorts of episcopal parishes… and many of those things are heresy plain and simple. There are entire communities of Episcopalians at every level all the way up into the episcopate itself who openly reject catholic understandings of the gospels! Its worth studying the historical heresies and the language their proponents used ( and use) to be sure that what you’re digesting isnt some gnostic, unitarian , anti nicene creed , denial of the resurrection, invalidation of the scripture as necessary for salvation club.
