No one denies that....they separated over the issue of leadership....they are still Catholic and will return to the fold...
I’m not referring to the Orthodox Churches; I’m referring to the Eastern Catholic Churches that are loyal to the Pope. Many have Orthodox counterparts. The Maronites, Syro-Malabar, Ukrainian Catholics, Greek Catholics, Chaldean Rite, etc. are Catholic Churches under the Pope (but they aren’t Latin Rite/”Roman Catholic”) - they often have married priests and don’t have statues, but they are Catholic with their own hierarchies leading to the Pope.
