In this book Addison Hodges Hart asks some pointed questions: What sort of church must we become in a post-Christendom world, one in which we can no longer count on society to support Christian ideals? What can we salvage from our Christendom past that is of real value, and what can we leave behind as not practical - and perhaps antithetical - for our discipleship? How do we become "strangers and pilgrims" once more, after seventeen centuries of being "at home" in Christendom? Hart's book takes up these various topics, suggesting both how Christ's disciples can say "yes" to much that was preserved during the age of Christendom, and why they should say "no" to some of the cherished accretions of that passing epoch.
