22. Life Together by Dietrich Bonhoeffer
I could just eat up this book. Some things are a little outdated and more liturgical than some would like, but I loved most of it.
As I am in reassessment mode about everything including how we do community, this had such yummy things to say about what community is and isn't.
Another book I heartily recommend! I have loved reading all these classics that Richard Foster recommended when I read Celebration of Discipline!
