In the Church’s traditional calendar, this final Sunday in October is celebrated as the Feast of Christ the King. This feast was implemented by Pope Piux XI in 1925 with Quas primas, in the face of secularism, the spread of materialistic atheistic Communism, and its cousins Fascism and Nazism.
Since Christ the King was implemented, the Church prays on this Sunday the
Act of Consecration of the Human Race to the Sacred Heart of Jesus
There’s nothing wrong with saying this prayer on other days! You might try it.
However, the Handbook of Indulgences says:
#27. A plenary indulgence is granted to the faithful, who piously recite the above Act of Dedication of the Human Race to Jesus Christ the King, if it is recited publicly on the feast of our Lord Jesus Christ the King, and piously carry out the precepts in Norm #23 listed above. [The grant probably refers to the Novus Ordo calendar and the Last Sunday of the Year. However, favoribilia amplianda.]
Requirements for Obtaining a Plenary Indulgence on Christ the King
- Public recitation of the prayer “Most Sweet Jesus, Redeemer – Act of Dedication of the Human Race to Jesus Christ King” (listed below)
- Say one “Our Father” and one “Hail Mary” for the intentions of the Pope
- Make a Sacramental Confession within a week of (before or after) the Feast of Christ the King
- Worthily receive Holy Communion (ideally on the Feast of Christ the King)
- that one be free from all attachment to sin, even venial sin.
Here is the prayer. Perhaps print it and ask your priests to say it:
Act of Consecration of the Human Race to the Sacred Heart of Jesus
Most Sweet Jesus, Redeemer of the human race, look down upon us humbly prostrate before Thine altar. We are Thine, and Thine we wish to be; but to be more surely united to Thee, behold each one of us freely consecrates ourselves 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 to Thy Sacred Heart. Be Thou King, O Lord, not only of the faithful children, 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 unity of faith, so that there may be but one flock and one Shepherd.
Be Thou King of all those who are still involved in the darkness of idolatry or of Islamism, and refuse not to draw them into the light and kingdom of God. Turn Thine eyes of mercy towards the children of the race, once Thy chosen people: of old they called down upon themselves the Blood of the Savior; may it now descend upon them a laver of redemption and of life.
Grant, O 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.
