when did the orthodox church split from the catholic church
East–West Schism The schism between the Western and Eastern Mediterranean Christians resulted from a variety of political, cultural and theological factors which transpired over centuries.[18] Historians regard the mutual excommunications of 1054 as the terminal event.[19] It is difficult to agree on an exact date for the event where the start of the schism was apparent.[20] It may have started as early as the[21] Quartodeciman controversy at the time of Victor of Rome (c. 180). Orthodox apologists point to this incident as an example of claims by Rome to papal primacy and its rejection by Eastern Churches.
