This post responds to Dr. Joshua Sijuwadeโs The Identity of the Church: A Comprehensive Argument for the Truth of Eastern Orthodoxy, which claims that the Eastern Orthodox Church best fulfills the Niceno-Constantinopolitan Creedโs vision of the โone, holy, catholic, and apostolic Church.โ While appreciating the intellectual rigor of Sijuwadeโs argument, the author challenges the underlying assumption that the one Church must correspond to a single, historically continuous institution. Drawing from Ephesians 4 and the teachings of Jesus, the post argues that the Churchโs unity is spiritual, not institutionalโrooted in the shared life of believers who abide in Christ and are joined together by the Spirit. The true continuity of the Church is the ongoing work of the Spirit among all who follow Jesus, not an unbroken chain of organizational lineage. Historic and structural continuity have value but do not define the Churchโs identity; faithfulness to Christ does. The Church, therefore, is not a denomination we can point to, but a people who together embody the love, faith, and hope of the gospel.
