The dispute with Burke is not Christology (where error is heresy, not apostacy, the great apostacy of prophesy has absolutely nothing to do with arguments about miracles, except the miracles of anti-Christ attracting the faithful to his side) but how we treat divorce and remarriage. As I and many understand it, he proposed (and it was accepted by Synod and codified in A.L.) that the West adopt a pastoral approach more in line with the Orthodox (although they-did not go as-far as a rite for remarriage). That line of thought and action is NOT heretical and certainly not Apostacy. It is Burke who is in error, both on charity and obedience.
