The popes teach devotion to the Sacred Heart of Jesus is the summary of our religion, of the whole mystery of our redemption. This makes perfect sense as it has to do with the infinite love of the Blessed Trinity for us. This devotion is directed towards the love of God for us. We are to adore His Sacred Heart, give thanks for It, and live so as to imitate It. It entails three kinds of devotion: of love, of reparation and of imitation. Consider the example of three saints: Gertrude the Great, Catherine of Siena and Clare of Montefalco. O Jesus, make my heart like unto Thine.
