The term caesaropapism is considered only partly accurate for the Byzantine Empire because it oversimplifies a complex, interdependent relationship between the state and the church. While the emperor managed administrative affairs and acted as a protector of the church, the Byzantine understanding of the faith did not recognize the emperor as doctrinally infallible or invested with priestly powers.12
Instead of unilateral submission, the ideal relationship was defined as symphonia (harmony)βa "dyarchy" where the emperor and the patriarch functioned like the body and soul of a single organism. Key factors that challenge the label of caesaropapism include:123
- Theological Limits: Emperors could not impose their will on matters of faith when it contradicted the conscience of the church, as evidenced by the failure of imperial attempts to enforce specific doctrines during the Iconoclastic Controversy and various failed attempts at union with Rome.12
- Ecclesiastical Resistance: Authoritative theologians and strong patriarchs frequently denied imperial authority over the church, occasionally excommunicating emperors for uncanonical acts.12
- Legal Framework: While nomocanons fused imperial and church law, the Epanagoge explicitly directed the patriarch to defend holy teachings without fear of the emperor.34
