On 2 February 2023, John Zizioulas, Orthodox hierarch of the Ecumenical Patriarchate and one of the most influential theologians of the past 50 years, passed away at age 92. He is known worldwide for his theology of communion, described in his two major works: Being as Communion (1985) and Communion and Otherness (2006). These books offer an attempt at a systematic theology that brings together various theological disciplines (such as triadology, Christology, ecclesiology, anthropology, pneumatology, and eschatology) based on the idea that being is communion. His opponents regarded him as a heretic and a modernist, while his supporters considered him one of the greatest minds of the Orthodox Church in history.
