text: If the visible head has cut himself off from the body is above our pay grade as laity to speak on...a future pope or ecumenical Council would have to speak on that (as the Third Council of Constantinople anathematized Honorius).  However the invisible head of the Church remains Jesus Christ regardless of the status His vicar on Earth. Our job is to hold fast to the faith. As St. Paul told us, if he or an angel preaches another Gospel, let him be anathema.
