YouTuber Dwong has an excellent collection of videos exposing Eastern Orthodox inconsistencies — especially their rejection of the
Filioque and other key doctrines.
Additionally,
The See of Peter hosts hundreds of papal letters and early Church docuмents, many translated into English for the first time. These writings clearly demonstrate that
the East was subject to Rome from the earliest centuries, and that the unique charisms of the Roman Pontiff — including
universal jurisdiction and infallibility — were widely acknowledged.
The Orthodox cannot escape this historical reality:
for the first thousand years, they were in full communion with Rome and part of the Catholic Church.
They broke away under Michael Cerularius in
1054, briefly returned at the
Council of Lyons II (1274) and the
Council of Florence (1439), only to be
permanently severed following the Muslim conquest of Constantinople in
1453.
