"The prayer of the Church venerates and honors the Heart of Jesus . . . which, out of love for men, he allowed to be pierced by our sins."2 Devotion to the Sacred Heart of Jesus is of great antiquity in the Church. It was St. Margaret Mary Alacoque, however, who made this devotion widespread. In 1675, within the octave of the feast of Corpus Christi, our Lord appeared to her and said: "Behold this heart which, not withstanding the burning love for men with which it is consumed and exhausted, meets with no other return from most Christians than sacrilege, contempt, indifference and ingratitude, even in the sacrament of my love [the Eucharist]. But what pierces my heart most deeply is that I am subjected to these insults by persons especially consecrated to my service."3
