From Pope Benedict’s address before the Sunday Angelus on 29 January:

Often for man authority means possession, power, dominance, success. For God, instead, authority means service, humility, love; it means entering into the logic of Jesus who stoops to wash the feet of his disciples (cf. John 13:5), who seeks man’s true good, who heals wounds, who is capable of a love so great that he gives his life, because he is Love. In one of her letters, St. Catherine of Siena writes: “It is necessary that we see and know, in truth, with the light of faith, that God is the Supreme and Eternal Love, and he cannot will anything if not our good” (Ep. 13 in: Le Lettere, vol. 3, Bologna 1999, 206).
