The devotion consists in the divine worship of the human heart of Christ, which is united to His divinity and which is a symbol of His love for us. The aim of the devotion is to make our Lord king over our hearts by prompting them to return love to Him (especially through an act of consecration by which we offer to the Heart of Jesus both ourselves and all that belongs to us) and to make reparation for our ingratitude to God.
O Heart of love, I put all my trust in Thee; for I fear all things from my own weakness, but I hope for all things from Thy goodness. (St. Margaret Mary Alacoque)
Indulgence of 300 days; plenary indulgence once a month on the usual conditions, if this invocation is repeated daily with devotion. (232)
Prayer to the Sacred Heart
Devotion to the Sacred Heart was the characteristic note of the piety of St. Gertrude the Great (1256-1302), Benedictine nun and renowned mystic. She was, in fact, the first great exponent of devotion to the Sacred Heart. In our efforts to honor the Heart of Jesus we have this prayer as a model for our own.
Hail! O Sacred Heart of Jesus, living and quickening source of eternal life, infinite treasure of the Divinity, burning furnace of divine love. Thou art my refuge and my sanctuary, O my amiable Savior. Consume my heart with that burning fire with which Thine is ever inflamed. Pour down on my soul those graces which flow from Thy love, and let my heart be so united with Thine, that our wills may be one, and mine in all things be conformed to Thine. May Thy divine will be equally the standard and rule of all my desires and of all my actions. Amen.
For the Church
O most holy Heart of Jesus, shower Thy blessings in abundant measure upon Thy holy Church, upon the Supreme Pontiff and upon all clergy; to the just grant perseverance; convert sinners; enlighten unbelievers; bless our relations, friends and benefactors; assist the dying; deliver the holy souls in purgatory; and extend over all hearts the sweet empire of Thy love. Amen.
Indulgence of 500 days; plenary indulgence once a month on the usual conditions for the daily devout recitation of this prayer. (262)
A Prayer of Trust
O God, who didst in wondrous manner reveal to the virgin, Margaret Mary, the unsearchable riches of Thy Heart, grant that loving Thee, after her example, in all things and above all things, we may in Thy Heart find our abiding home.
Act of Love
Reveal Thy Sacred Heart to me, O Jesus, and show me Its attractions. Unite me to It for ever. Grant that all my aspirations and all the beats of my heart, which cease not even while I sleep, may be a testimonial to Thee of my love for Thee and may say to Thee: Yes, Lord, I am all Thine; the pledge of my allegiance to Thee rests ever in my heart and will never cease to be there. Do Thou accept the slight amount of good that I do and be graciously pleased to repair all my wrong-doing; so that I may be able to bless Thee in time and in eternity. Amen.
Cardinal Merry Del Val
Indulgence of 500 days; plenary indulgence on the usual conditions, if this prayer is recited daily for a month. (267)
Memorare to the Sacred Heart
Remember, O most sweet Jesus, that no one who has had recourse to Thy Sacred Heart, implored its help, or sought its mercy was ever abandoned. Encouraged with confidence, O tenderest of hearts, we present ourselves before Thee, crushed beneath the weight of our sins. In our misery, O Sacred Heart of Jesus, despise not our simple prayers, but mercifully grant our requests.
