Devotion to the Sacred Heart of Jesus is devotion to Jesus Christ Himself, but in the particular ways of meditating on his interior life and on His threefold love — His divine love, His burning love that fed His human will, and His sensible love that affects His interior life.
From the time of Saint John and Saint Paul there has always been in the Church something like devotion to the love of God, Who so loved the world as to give it His only-begotten Son, and to the love of Jesus, Who has so loved us as to deliver Himself up for us. But, accurately speaking, this is not the devotion to the Sacred Heart, as it pays no homage to the Heart of Jesus as the symbol of His love for us. From the earliest centuries, Christ’s open side and the mystery of blood and water were meditated upon, and the Church was beheld issuing from the side of Jesus, as Eve came forth from the side of Adam. But there is nothing to indicate that, during the first ten centuries, any worship was rendered the wounded Heart.
