The central proposition of Christianity is stupendous: the core of reality is a personal deity who loves you. Joseph Ratzinger explains:
At the very moment when the Magi, guided by the star, adored Christ the new King, astrology came to an end because the stars were now moving in the orbit determined by Christ… It is not the elemental spirits of the universe, the laws of matter, which ultimately govern the world and mankind, but a personal God.
