“It is possible that Christians may remain lonely in spite of daily worship together, prayer together, and all their community through service – that the final breakthrough to community does not occur precisely because they enjoy community with one another as pious believers, but not with one another as those lacking piety, as sinners. For the pious community permits no one to be a sinner. Hence all have to conceal their sins from themselves and from the community. We are not allowed to be sinners.”
Dietrich Bonhoeffer, Life Together, Prayerbook of the Bible, Works vol. 5, Fortress, 2005, 108.
Bonhoeffer graduated from the University of Berlin in 1927, at age 21, and then spent some months in Spain as an assistant pastor to a German congregation. Then it was back to Germany to write a dissertation, which would grant him the right to a university appointment. He then spent a year in America, at New York’s Union Theological Seminary, before returning to the post of lecturer at the University of Berlin.
