This morning I published a reflection on the Annunciation and what it means that its celebration, also known as Lady Day, falls during Lent. I would like to add, however, one other thought on the holiday.
Tomorrow is Tolkien Reading Day, an international holiday organized by the Tolkien Society, in which enthusiasts are encouraged to read their favorite passages from the great storyteller. Why March 25th? According to the Society's website, the date was chosen because this is the day Sauron was defeated and Barad-dûr thrown down. Now I have not investigated the matter in any detail, but I think it is unlikely to be mere coincidence that Tolkien chose this major feast day - one of the four great medieval Quarter Days - as the day in which good triumphs over evil in The Lord of the Rings. I can only conclude that he saw in the Incarnation of God's only Son a similar triumph of good over evil.
(And a quick check of the internet suggests I am definitely not the first to notice this non-coincidence!)
