their core. Deliberate Christ figures in Frodo, Aragorn, and Gandalf. Leaves Rivendell on the quest to save mankind on Christmas and the destruction of the ring occurs on the traditional day of Easter per some religious calendars. Clear Christian teachings. The books are awesome.
The movies? Great, but not nearly as Christian as the books. But I think there's a reason why those are movies and books are timeless where other "great" movies fade. Christ and His goodness are the underlying themes, and those themes speak to our souls whether we realize it or not.
