Nothing so tends to mask the face of God as religion; it can be a substitute for God himself.
Martin BuberSince the primary motive of the evil is disguise, one of the places evil people are most likely to be found is within the church. What better way to conceal one's evil from oneself, as well as from others, than to be a deacon or some other highly visible form of Christian within our culture? ... I do not mean to imply that the evil are anything other than a small minority among the religious or that the religious motives of most people are in any way spurious. I mean only that evil people tend to gravitate toward piety for the disguise and concealment it can offer them.
