Book excerpt: Expanding their foundational work on collaborative ministry, these bestselling authors now offer thirty principles for effective, spiritually healthy, mission-focused ministry. Disciplines like set boundaries; facilitate, dont dominate; think developmentally; be comfortable with conflict; and avoid ambiguity are presented with real-world stories, compelling commentary, and follow-up exercises that reinforce and help the reader apply what has been learned. Arranged into five chapters, the principles are explored in light of the best servant-leadership theory and praxis and situated within a variety of contexts and ministerial settings in the Catholic Church. An ancillary workbook, available for free download, helps both the apprentice and well-seasoned Church leader immediately apply the lessons and incorporate the disciplines presented in this eminently practical and vitally needed book.
