The Greek Orthodox would disagree with you as would everyone else NOT Roman Catholic.
The Eastern schism did, indeed, deny the authority of the Pope....that changes nothing....when they return to the fold, and they will, we will all again be under his direct authority. As far as the remainder of Christianity is concerned....they decided to change whatever rules that they didn't like and they did so. Never mind the seven Sacraments, never mind transubstantiation, never mind Penance nor Holy Orders, Infant Baptism, who needs it??...The Eucharist, merely a symbolic meal with no real meaning....and the Popes from Peter on down, oh well we are now all our own Popes and make our own rules...
Good luck with that....sounds like free for all time at the local kindergarden..
