Life Together was written by Dietrich Bonhoeffer while he was in a Nazi Gestapo prison during WWII. The book's Introduction is a 6 page mini-bio of Bonhoeffer, which will inform the reader as to why he was in a Nazi Gestapo prison. He was executed by the Nazi's just weeks before the end of the war.
Life Together was written while Bonhoeffer was being held by the Nazi's. It is his short treatise on Faith in Community - what it means to be the Body of Christ. During his time in prison, Bonhoeffer undoubtedly had interaction with Christians of many denominations. This probably led to contemplation of what it meant for all of them to worship together, even in a prison camp.
The book is just five chapters:
2. The Day with Others
3. The Day Alone
5. Confession and Communion
Amazingly enough, Bonhoeffer thinks seriously and deeply about what it should be like for Christians to experience Life Together as the Church. Few current authors are packing so much in so little a book.
In the first chapter he looks at relating to one another as Jesus would have us relate to one another. He distinguishes between the worldly and the biblical concepts of living in community. His observations are astounding and would do many churches a great deal of good today.
In chapters 2 and 3, he looks at one's relationship with God as it should be lived both corporately and individually. He even gives us a glimpse of what family worship was expected to look like at that time. Again, his observations would do Christians much good today.
The chapter on ministry is outstanding, but one really cannot do it justice in just a few sentences. The final chapter on confession and communion was a mixed bag for me. His ideas on confession were pretty good. However, his beliefs on communion are different from my beliefs (he was a Lutheran, I am a Baptist). Even still, I would recommend reading this chapter with one's eyes open.
When all is said and done, this is a wonderful book. It was written in 1940's German and translated to English, so there are some places where the translation is not always the clearest. The reader should know that Bonhoeffer was not only a pastor, but also a theologian - his writing is meaty, not fluffy. For those brave enough to sink their teeth in, this book will be a great read (and probably a great re-read). There is much to learn in this little book. I even found that much of this book can be applied within the marriage context. Read, enjoy, apply it to all aspects of your life.
