King of kings and Lord of lords: The Reign of Christ the King!

"His empire includes not only Catholic nations, not only baptized persons who, though of right belonging to the Church, have been led astray by error, or have been cut off from her by schism, but also all those who are outside the Christian faith; so that truly the whole of mankind is subject to the power of Jesus Christ."

- Pope Leo XIII

Christus vincit, Christus regnat, Christus imperat!

It has long been a common custom to give to Christ the metaphorical title of "King," because of the high degree of perfection whereby he excels all creatures. So he is said to reign "in the hearts of men," both by reason of the keenness of his intellect and the extent of his knowledge, and also because he is very truth, and it is from him that truth must be obediently received by all mankind. He reigns, too, in the wills of men, for in him the human will was perfectly and entirely obedient to the Holy Will of God, and further by his grace and inspiration he so subjects our free-will as to incite us to the most noble endeavors. He is King of hearts, too, by reason of his "charity which exceedeth all knowledge." And his mercy and kindness which draw all men to him, for never has it been known, nor will it ever be, that man be loved so much and so universally as Jesus Christ. But if we ponder this matter more deeply, we cannot but see that the title and the power of King belongs to Christ as man in the strict and proper sense too (Eph. iii, 9). For it is only as man that he may be said to have received from the Father "power and glory and a kingdom," (Dan. vii, 13-14) since the Word of God, as con-substantial with the Father, has all things in common with him, and therefore has necessarily supreme and absolute dominion over all things created.

The foundation of this power and dignity of Our Lord is rightly indicated by Cyril of Alexandria. "Christ," he says, "has dominion over all creatures, a dominion not seized by violence nor usurped, but his by essence and by nature." His kingship is founded upon the ineffable hypostatic union. From this it follows not only that Christ is to be adored by angels and men, but that to him as man angels and men are subject, and must recognize his empire; by reason of the hypostatic union Christ has power over all creatures. But a thought that must give us even greater joy and consolation is this that Christ is our King by acquired, as well as by natural right, for he is our Redeemer. Would that they who forget what they have cost their Savior might recall the words: "You were not redeemed with corruptible things, but with the precious blood of Christ, as of a lamb unspotted and undefiled" (I Pet. i, 18-19). We are no longer our own property, for Christ has purchased us "with a great price" (1 Cor. vi, 20); our very bodies are the "members of Christ" (I Cor. vi, 15).

ON THE FEAST OF CHRIST THE KING

Act of Dedication of the Human Race to Jesus Christ the King

Pope Leo XIII

Most sweet Jesus, Redeemer of the human race, look down upon us humbly prostrate before Thy altar. 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 to Thy Sacred Heart. Be Thou King, O 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 unity of faith, so that soon 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 to draw them all into the light and kingdom of God. Turn Thine eyes of mercy towards the children of that 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 be to the Divine Heart that wrought our salvation; to It be glory and honor for ever." Amen.

Most Sacred Heart of Jesus, Have Mercy on Us!

"[T]he Heart of the Incarnate Word is deservedly and rightly considered the chief sign and symbol of that threefold love with which the divine Redeemer unceasingly loves His eternal Father and all mankind.

It is a symbol of that divine love which He shares with the Father and the Holy Spirit but which He, the Word made flesh, alone manifests through a weak and perishable body, since 'in Him dwells the fullness of the Godhead bodily.'

It is, besides, the symbol of that burning love which, infused into His soul, enriches the human will of Christ and enlightens and governs its acts by the most perfect knowledge derived both from the beatific vision and that which is directly infused.

And finally—and this in a more natural and direct way—it is the symbol also of sensible love, since the body of Jesus Christ, formed by the Holy Spirit, in the womb of the Virgin Mary, possesses full powers of feelings and perception, in fact, more so than any other human body.

Since, therefore, Sacred Scripture and the official teaching of the Catholic faith instruct us that all things find their complete harmony and order in the most holy soul of Jesus Christ, and that He has manifestly directed His threefold love for the securing of our redemption, it unquestionably follows that we can contemplate and honor the Heart of the divine Redeemer as a symbolic image of His love and a witness of our redemption and, at the same time, as a sort of mystical ladder by which we mount to the embrace of 'God our Savior.'"

- HAURIETIS AQUAS (On Devotion To The Sacred Heart) Pope Pius XII, May 15, 1956

ACT OF ADORATION TO THE SACRED HEART 
by St. Margaret Mary Alacoque

With all the power of my heart, I now adore Thy sovereignty, O most Sacred, Divine and Adorable Heart of Jesus, whom I wish to fear and respect with continuous attention never more to offend Thee because Thou art infinitely good. O most Sacred Heart, I love Thee and wish to love Thee above all things with all my strength and power. I detest every mortal sin and all voluntary venial sins; I hope that as we belong to Thee, who hast given birth to us on the Cross with so much pain, Thou wilt have pity on our weakness and misery and not allow us to perish.

I offer myself entirely to Thee, O Heart of love, with the intention that my whole being, my life and my sufferings may be employed in loving, honoring and glorifying Thee in time and in eternity. I love Thee, O most amiable Heart, as my sovereign good, my entire happiness and all my joy, as the sole object worthy of the love of all hearts. May my heart be reduced to cinders by the ardor and vehemence of this love, by which I renew with my whole soul all the offerings which I have made to Thee of myself. Keep me from displeasing Thee and grant me to do what is most pleasing to Thee. O Heart, Source of pure love, would that I might be all heart to Thee and all soul to adore Thee! Grant that by Thy holy grace, I may be able to love only Thee, to love in Thee and by Thee and for Thee. May my memory think only of Thee, may I have no other understanding but to know Thee, no other will or affection but to love Thee, no tongue but to praise Thee, no eye but to see Thee, no hands but to serve Thee, no feet but to seek Thee, in order that I may be able one day to love Thee without fear of losing Thee for all eternity. Amen.
