In this book Addison Hodges Hart articulates some crucial questions for contemporary Christians: What sort of church must we become in today's post-Christendom world, where 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 properly leave behind? How do we become "strangers and pilgrims" once more, after being "at home" in Christendom for so long?

Summoning readers to wise and faithful discipleship in our post-Christendom age, Hart suggests 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.
