[Bonhoeffer] would write [his doctoral dissertation] about a subject he had begun puzzling over in Rome, namely, What is the church? It was eventually titled Sanctorum Communio: A Dogmatic Inquiry into the Sociology of the Church. Bonhoeffer would identify the church as neither a historical entity nor an institution, but as “Christ existing as church-community.”
What is the church? We want to identify it with a building or a denomination but it is so much more, existing actually in a different dimension. I would love to read this dissertation (if I am even up to reading scholarship at this level).
