After traumatic events, many (especially young people) turn away from the Church; Post-Traumatic God presents a path home, providing a way back to a God who can be trusted, loved, and worshipped.
Today, the church is sometimes viewed (even from within) as a place apart, which may create a barrier of understanding for those who have experienced trauma. Post-Traumatic God grew out of Peters' own experience as a chaplain in Iraq and later as an Episcopal priest, and from his subsequent work with an organization he founded, the Episcopal Veterans Fellowship, which helped him identify the need for this quite-different book to bridge that gap. In it, Peters explores three related themes: history (the early church itself was a post-traumatic community); theology (especially building on Tillich's World War I experiences and the theology he subsequently developed); and ecclesiology (how church can offer community to trauma survivors. Post-Traumatic God equips the Church to heal the unseen wounds of the soul.
