Prayer of Consecration to the Sacred Heart by Pope Leo XIII

Issued with the Encyclical Letter Annum Sacrum, 25 May 1899

Most sweet Jesus, redeemer of the human race, look down upon us, humbly prostrate before your altar. We are yours and yours we wish to be; but to be more surely united with you, behold each one of us freely consecrates himself today to your most sacred heart. Many, indeed, have never known you, many too, despising your precepts, have rejected you. Have mercy on them all, most merciful Jesus, and draw them to your sacred heart. Be you king, O Lord, not only of the faithful who have never forsaken you, but also of the prodigal children who have abandoned you; grant that they may quickly return to their father's house, lest they die of wretchedness and hunger. Be you king of those who are deceived by erroneous opinions, or whom discord keeps aloof, and call them back to the harbor of truth and unity of faith, so that soon there may be but one flock and one shepherd. Be you king also of all those who sit in the ancient superstition of the Gentiles, and refuse not you to deliver them out of darkness into the light and kingdom of God. Grant, O Lord, to your Church, assurance of freedom and immunity from harm; give peace and order to all nations, and make the earth resound from pole to pole with one cry: Praise to the divine heart that wrought our salvation; to it be glory and honor forever.
Amen.
