An Act of Consecration of the Human Race to the Sacred Heart of Jesus
This consecration was written by Pope Leo XIII in 1899.
Most kind Jesus, Redeemer of the human race, look down upon us humbly kneeling before Thee. We are Thine, and Thine we wish to be; but, to be more surely united with Thee, behold each one of us freely consecrates himself today to Thy most Sacred Heart. Many indeed have never known Thee; many too, despising Thy precepts, have rejected Thee. Have mercy on them all, most merciful Jesus, and draw them all to Thy most Sacred Heart.
Be Thou King, 0 Lord, not only of the faithful who have never forsaken Thee, but also of the prodigal children who have abandoned Thee; grant that they may quickly return to their Father's house lest they die of wretchedness and hunger.
Be Thou King of those who are deceived by erroneous opinions, or whom discord keeps aloof, and call them back to the harbor of truth and the unity of faith, so that soon there may be but one flock and one Shepherd. Grant, 0 Lord, to Thy 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.
