Autonomy, autocephaly and Patriarchate – key notions in understanding a centenary

Autonomy, autocephaly and Patriarchate – key notions in under- standing a centenary In light of the centenary celebration of the Romanian Patriarchate, this study considers it essential to highlight the key concepts necessary for understanding the complexity of this institutional development and its role. Accordingly, the present research defines the notions of autonomy, autocephaly, the Patriarchate, and the Patriarch, examining their historical significance, func- tions, and evolving dynamics over time. Drawing on canonical sources as well as relevant secondary literature, the study approaches these topics through historical, cultural, and political perspectives, while also interpreting them as expressions of Byzantine heritage and as integral to contemporary understandings of Orthodoxy and its role in the modern world. A central focus is placed on the interrelationship among these concepts, understood as stages in the gradual evolution of a Church shaped by social, ethnic, and territorial realities, as well as by the spiritual maturity of its leaders.
