Across the United States, evangelical churches are failing to protect victims of sexual abuse among their members. While some church leaders have worked to prevent abuse and harassment, many have not. The causes are manifold: authoritarian leadership, twisted theology, institutional protection, obliviousness about the problem and, perhaps most shocking, a diminishment of the trauma sexual abuse creates - especially surprising in a church culture that believes strongly in the sanctity of sex.

As a prosecutor, Tchividjian saw dozens of sexual abuse victims harmed by a church's response to them. In 2004, Tchividjian founded [a] nonprofit organization ... which trains Christian institutions in how to prevent sexual abuse and performs independent investigations. Tchividjian says sexual abuse in evangelicalism rivals the Catholic Church scandal of the early 2000s. According to research from the evangelical publishing company LifeWay ... pastors drastically underestimate the number of victims in their congregations.
