Secularization, as a movement away from a religious orientation to life, is strong in Canada and has influence worldwide. In this volume, missiologists and practitioners across Canada consider how an agenda of Christian mission and evangelism can be advanced in a secularizing environment. How can believers be curious and engaged rather than defensive and fearful? What changes are required from the evangelical community so that there is productive dialogue and action in ways that maintain faithfulness to the cause of Christ? What should the approach of mission be to a new generation steeped in secular narratives? How do we answer negative caricatures of Christian mission in light of the history of Residential Schools? What examples from the past teach us about developing an irenic approach? What positive trends are currently evident in Canada and around the world that counter the secularizing narrative? These questions and more are considered in this volume by Canadian scholars who recognize the importance of being relevant to society while maintaining integrity with the Gospel message. The essays address secularism in Canadian and worldwide contexts with seriousness, insight, and an underlying theme of hope, recognizing that God’s mission has been accomplished, is being accomplished, and will be accomplished.
