Using the Seven Ecumenical Councils as backbone, Hore provides the reader with an overview of the Greek Orthodox Church. Writing in an era when the Oxford Movement was reaching a wide array of Anglicans with the forgotten connections with orthodoxy, Hore presents a sympathetic view of Byzantine Christianity. Following the trials and difficulties of the early church after it received imperial approval, a sketch of the Greek Church, including the "separatist" Churches, emerges.
