Book excerpt: Written from a post-Christendom/emergent worldview, this books was born of a singular question asked in hundreds of ways: "What do we do to be faithful in this changed and changing reality?" Whether shaped by anxiety, a foretaste of coming changes, excitement, or energy at the prospects of witness and service the future holds, the question remains the same and the answers elusive. Part one addresses church functions under categories of governance, modeling, collaboration, champion, catalyst, mission, covenant, disciple, change and leadership. Part two offers further explication of the functions, including books recommended for in-depth study, application ideas, and further exploration of themes.
