Well, that would cause problems, because these Eastern Rites have always been a part of Rome. They either did not participate or weren’t around at the time of the Schism.
If the Orthodox are willing to accept Petrine supremacy, then we can talk about reordering things in the east. Until then, we shall see.
I have no problem whatsoever with the Eastern rites retaining their traditions in the west.
Sorry, we cannot accept heresy in the name of false union. Saint Mark of Ephesus, pray for us!
