“If Christmas time cannot ignite within us again something like a love for holy theology, so that we—captured and compelled by the wonder of the manger of the Son of God—must reverently reflect on the mysteries of God, then it must be that the glow of the divine mysteries has also been extinguished in our heart and has died out.”
