In his first book, Fellowship of the Ring, J.R.R. Tolkien describes the camaraderie of a diverse group, banded together by a common cause. Called "the fellowship of the ring," their quest is to destroy the power of the Dark Lord lodged in his ring. Though they differ in nearly every way—racially, physically, temperamentally—they are united in their opposition of the Dark Lord. In a section omitted in the movie, a heated conflict breaks out among the crusaders. Axes are drawn. Bows are bent. Harsh words are spoken. Disaster nearly strikes the small band. When peace at last prevails, a wise counselor observes, "Indeed in nothing is the power of the Dark Lord more clearly shown than in the estrangement that divides all those who still oppose him."

Today, the Dark Lord —Satan— shows his power when there is discord among believers.
