In his remarks before the conclave that wound up naming him as Pope, then Cardinal Bergoglio speaks about the need for the Church to evangelize and not become self-referential and narcissistic. What this means for the Church will be written about by Pope Francis and many theologians. What struck me was his reference to the mysterium lunae, the mystery of the moon. The moon is the brightest object in the night sky, yet unlike the other stars in the sky, it has no light of its own. It only reflects the light of the nearest star, the Sun. Likewise, in the words of St. Ambrose, ” the Church shines not with its own light, but with that of Christ,” (“fulget Ecclesia non suo sed Christi lumine.”) We would probably do well to remember that it is by the light of Christ reflected from the Church that we see through the darkness.
