1, Rome called the crusade, and never excommunicated the Bishops who preached that the crusaders were pre-forgiven for any sins in it’s taking. Further Rome has never returned the ‘booty’.
2. I don’t beleive the Pope is forbidden entry into Russia. Either way since the Pope is not the leader of a church in communion with the Orthodox, why would he be treated as anything other than the leader of a non-Orthodox group?
3. The filioque was added outside of a council so regardless of primacy the Pope excommunicated himself according to the canons of the councils which forbade changes.
4. There is no such primacy in scripture, where questions of doctrine are resolved in councilar form in the presence of the Holy Spirit, not by someone who arbitrarily decides they’re infailable by suggesting they were sitting down when they issued they’re decree however heretical or blasphemous it might actually be.
5. Of 5 Sees only one left the church, and that same one has since decided that it’d patriarch is infailable. He’ll have ex-ray vision soon too if there is not a return to deffering to the councils and the holy spirit.
