What does it mean for Christians to enter into the unfolding story of digital evangelization as participants rather than passive consumers? This handbook narrates the ongoing media efforts of Christians—from the 1960s to the twenty-first century—to communicate the gospel in the modern age and draws powerfully from the story of how one group of seventy-four people sought spiritual growth via an interactive digital Ignatian retreat on Facebook. Written by a Jesuit priest with years of experience in journalism as well as spiritual formation, the book draws lessons from these stories to present a “how-to” guide for individuals and groups seeking more effective ways to share faith on social media.
