The medieval theologian William of Saint Thierry once said that God – from the time of Adam – saw that his grandeur provoked resistance in man, that we felt limited in our own being and threatened in our freedom. Therefore God chose a new way. He became a child. He made himself dependent and weak, in need of our love. Now – this God who has become a child says to us – you can no longer fear me, you can only love me.
From The Homily of His Holiness Pope Benedict XVI at the 2008 Christmas Midnight Mass (Hat-tip to Titus One Nine)
