Life Together, by Dietrich Bonhoeffer ★★★
Bonhoeffer wrote this book on returning to a Germany that was then controlled by Hitler. Through his experiences in the community at Finkenwalde in 1938, he writes of the nature of Christians living together. He describes a community that is focused on reading the Scriptures together and praying. He discusses the role of loving each other and confessing sin with each other. He develops the necessity of Christians living in the community. Though he doesn’t specifically breach the issue of “church”, it seems to be implied in all that he says, as well as what you see in Bonhoeffer’s life.
