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.
