03 — The Photian Crisis and the Council of 879–880
The ninth-century collision between St. Photius the Great and Pope Nicholas I rehearsed every element of the later schism — papal jurisdiction, the Filioque, missionary rivalry — and then showed, in the council of 879–880, that the breach could be healed by a true council on the common faith. This section gives the outline and its meaning for the schism; the full story lives in the sibling collection St. Photius the Great, to which these files defer.
Tradition: Pan-Orthodox
