Today is a perfect day for me! I love this feast for all sorts of different reasons.
I love it because it is slightly quirky. Nowhere in scripture is anything at all mentioned about the birth of Mary. All we can really say, unless we believe that Jesus arrived on earth via space ship, is that it happened.
I love it, because who could not love something whose source is a second century document entitled the Protoevangelium of James. While the feast itself may not date to the second century, the very human desire to know more about the people we love, and honour is as real desire.
