Ahí van unas pinceladas de un profesor norteamericano acerca de las relaciones entre El Señor de los Anillos y el cristianismo:
The most fundamental Christian symbol is the Cross. This also is perfectly opposite to the Ring. The Cross gives life; the Ring takes it. The Cross gives you death, not power; the Ring gives you power even over death. The Ring squeezes everything into its inner emptiness; the Cross expands in all four directions, gives itself to the emptiness, filling it with its blood, its life. The Ring is Dracula's tooth. The Cross is God's sword, held at the hilt by the hand of Heaven and plunged into the world not to take our blood but to give us His. The Cross is Christ's hypodermic; the Ring is Dracula's bite. The Cross saves other wills; the Ring dominates other wills. The Cross liberates; the Ring enslaves.
