Dr. Donald Wallenfang, OCDS offers commentary on Greek Orthodox Metropolitan John Zizioulas' 1997 book Being as Communion.
This classic text in ecclesiology is rich in its ecumenical reach, and yet shows the important differences between Catholic and Orthodox ecclesiologies so as to enrich both.
Topics include church authority, apostolic succession, the Eucharist, the missionary activity of the church, and the existential crisis of faith.
