As I read through Oman's treatment of the Dark Ages, I am struck again and again by his references to Catholics (which seems in a contextual sense to mean Christian orthodoxy writ large) and what I read as the seeds of the Great Schism of 1054.
Before the Iconoclast dispute, the Henoticon seems to have created an uproar. I am at a loss to understand why, beyond the usual problems of counting how many angels can dance on the head of a pin. As I understand the document, it was an attempt to heal the rift between the Monophysites and the rest of Christian orthodoxy at the time.
On what theological basis did the bishop of Rome excommunicate the Patriarch Acacius, for assisting Zeon in drafting the Henoticon?
