Book excerpt: Crossing social, cultural, and religious barriers and making disciples of all nations has probably never been without some level of controversy. This book is an attempt to hit the pause button on this rapid-paced world and to reflect on how we do mission, especially in light of the new layers of complexity that globalization brings. While the contributors engage in new aspects of mission and cultural encounter unique to the twenty-first century, the underlying issues of each chapter are age-old topics that have reared their heads at various times throughout history: priorities in mission, power struggles, perspectives on cultural others, and contextualization. With that in mind, our aims are twofold: (1) to carefully consider issues causing tension and contention within current mission thought, practice and strategy and then (2) to engage in serious but charitable dialogue for the sake of God’s mission and the salvation of all peoples.
