"From the earliest ages of the catholic church a Christian people, whether in time of triumph or more especially in time of crisis, has addressed prayers of petition and hymns of praise and veneration to the Queen of Heaven. And never has that hope wavered which they placed in the Mother of the Divine King, Jesus Christ; nor has that faith ever failed by which we are taught that Mary, the Virgin Mother of God, reigns with a mother's solicitude over the entire world, just as she is crowned in heavenly blessedness with the glory of a Queen. (...)

 47.  Since we are convinced, after long and serious reflection, that great good will accrue to the Church if this solidly established truth shines forth more clearly to all, like a luminous lamp raised aloft, by Our Apostolic authority We decree and establish the feast of Mary's Queenship, which is to be celebrated every year in the whole world on the 31st of May. We likewise ordain that on the same day the consecration of the human race to the Immaculate Heart of the Blessed Virgin Mary be renewed, cherishing the hope that through such consecration a new era may begin, joyous in Christian peace and in the triumph of religion.
 
   48 Let all, therefore, try to approach with greater trust the throne of grace and mercy of our Queen and Mother, and beg for strength in adversity, light in darkness, consolation in sorrow; above all let them strive to free themselves from the slavery of sin and offer an unceasing homage, filled with filial loyalty, to their Queenly Mother. Let her churches be thronged by the faithful, her feast-days honored; may the beads of the Rosary be in the hands of all; may Christians gather, in small numbers and large, to sing her praises in churches, in homes, in hospitals, in prisons. May Mary's name be held in highest reverence, a name sweeter than honey and more precious than jewels; may none utter blasphemous words, the sign of a defiled soul, against that name graced with such dignity and revered for its motherly goodness; let no one be so bold as to speak a syllable which lacks the respect due to her name. (...)

50. In some countries of the world there are people who are unjustly persecuted for professing their Christian faith and who are deprived of their divine and human rights to freedom; up till now reasonable demands and repeated protests have availed nothing to remove these evils. May the powerful Queen of creation, whose radiant glance banishes storms and tempests and brings back cloudless skies, look upon these her innocent and tormented children with eyes of mercy; may the Virgin, who is able to subdue violence beneath her foot, grant to them that they may soon enjoy the rightful freedom to practice their religion openly, so that, while serving the cause of the Gospel, they may also contribute to the strength and progress of nations by their harmonious cooperation, by the practice of extraordinary virtues which are a glowing example in the midst of bitter trials.

Supplication to the Compassionate Heart of Mary for the Church

O Queen of Martyrs! Who hast, in every age, overthrown heresies, stretch forth the arm of thy power against the spirit of Satan, now unchained upon earth, and against the men of sin, who have become his agents. Behold the impious war which they do not cease to wage against Jesus Christ, thy Son, His Vicar, His Church, His Priests, and His Children. See, the ruins which they have heaped around us, the waves of blood which they have caused to flow, the countless souls which they have perverted, and cast into hell.

O! Holy Virgin, powerful Help of Christians, we entreat thee, come to our aid. Come quickly with the celestial army, especially the intrepid Archangel Michael. Kindle in all hearts, especially in the hearts of Priests, the sacred fire of most ardent zeal. Place thyself at our head, august Mother of the God of hosts, and lead us to the battle. Sustain us by thy prayers; encourage us by thine eye. Scatter before us these new infernal legions, as the wind scatters the clouds. Powerful Help of Christians, give us victory, give us triumph and peace; obtain for us a holy life and a holy death. Amen.

Who is like to God, quis ut Deus?
Who is like to Jesus, Son of God and of Mary, quis ut Jesus?
Amen.

"Jesus, Good Shepherd, You sent us the Holy Spirit to guide Your Church and lead her faithful to You through the ministry of Your priests.

Through the inspiration of the Holy Spirit, grant to Your priests wisdom in leading, faithfulness in teaching, and holiness in guarding Your sacred Mysteries.

As they cry out with all the faithful, "Abba, Father!" may Your priests be ever more closely identified with You in Your divine Sonship and offer their own lives with You, the one saving Victim. Make them helpful brothers of one another, and understanding fathers of all Your people. On this Pentecost Sunday, renew in Your priests deeper faith, greater trust in You, childlike reliance on our Mother Mary, and unwavering fidelity to the Holy Father and his bishops.

Holy Mary, intercede for your priests.
St. Joseph, protect them.
St. Michael, defend them.
St. John Vianney, pray for them.
Amen."

On Other Exercises of the Love of God

"Consider first, that divine love is also exercised in the penitential way by souls that, like Magdalene, (of whom our Lord pronounced that many sins were forgiven her because she loved much,) go daily to the feet of Christ, in spirit, to wash them with their tears, flowing from a heart full of a sense of the infinite goodness of God, and of a deep regret for having offended that infinite goodness by their sins. This exercise of penitential love, as we see in the case of Magdalene, is most acceptable to out Lord, and most effectual for obtaining the discharge of all our sins; and, if diligently pursued, is capable of advancing even those that have been the greatest sinners to a high degree of virtue and sanctity. And whosoever has forfeited his baptismal innocence by mortal sin, if he would follow the rules of Christian prudence in choosing the safest way in a case where his all is at stake, should endeavor to pursue this exercise of penitential love, and never end it but with his life. Thus did all those great penitents of old who became afterwards such glorious saints. And this kind of exercise of love will become in a manner natural to all such as have a right sense of what God is and what sin is, and of the dreadful evil they have been guilty of in offending, though it were but once in their life, so great and so good a God.

Consider 2ndly, that there are also other ways of mourning in which we may exercise a love of God, most agreeable to him, and beneficial to ourselves. As when we sit down at the foot of the cross, and there contemplating the extreme anguish and distress, the stripes and wounds, the racking pains and torments of our dear Redeemer, with all that complication of sufferings in all kinds which he endured in his passion for the love of us, we excite in our souls suitable affections of an ardent love in the way of compassion for our crucified Lover, and feed this fire with tears, flowing at the sight of his blood; which, as it shows forth in the most sensible manner his tender affection for us, so it most strongly calls for a return of our love, accompanied with a bitter grief to see our beloved treated with so much cruelty and contempt. Upon the same principle of the concern that every true lover has, to see the outrages offered to his beloved, we may also exercise a love most agreeable to our Lord, in mourning for the innumerable sins that are daily committed against him throughout the whole world; to see his infinite goodness slighted, his sacred laws and ordinances trodden under foot, his mercies continually abused, and his most adorable majesty treated with the utmost contempt, by poor blind mortals, made by him, and for him redeemed by the blood of his Son, and loaded with innumerable favors, to engage them to love him and serve him. Oh! how can any true lover of God endure to see these outrages offered to his infinite majesty without having his heart perfectly broken with grief to see his Love thus abused?

Consider 3rdly, that, besides these exercises of the love of benevolence in the penitential and compassionate way, there is another most perfect exercise of love, and which comes the nearest to the love of the blessed in heaven; and that is, in the way of joy and congratulation - as when we rejoice in God and in his boundless perfections; when we are delighted to think that he is what he is, infinitely good, infinitely holy, infinitely happy, infinitely perfect; that he is the sovereign Lord of all, and that nothing can be added to him, because he is every way infinite. O, what a comfort, what a pleasure, what a joy it is to a true lover of God to think that whatsoever may come to himself, or to any other thing in the world, his Love at least, whom he loves without comparison more than himself and all things else, will always be infinitely glorious, infinitely rich, and infinitely happy! O how like is this love to that of the blessed, even to that love that makes them blessed, which is an eternal joy in God and in all the beauties and perfections they contemplate in him - this is their eternal delight.

Conclude to dedicate thyself for time and eternity to this most perfect love of God. Make it thy employment here, and it will be thy eternal reward hereafter. In the mean time, labor also to promote as much as thou canst, upon every occasion, the praise and glory of thy maker, the interests of his kingdom, the fulfilling of all his wills, as well in thyself as in all others; be concerned at every thing that displeases him, put thy heart continually in his hands, give thyself and all things else to him a hundred times in the day. Such acts as these, frequently repeated in the day, will secure to thee the rich treasure of divine love; by such exercises thou wilt effectually choose the better part, which will never be taken from thee."

On Acts of Divine Love

"Consider first, that the love of God is like a fire: its nature is to be always in motion, and always tending upwards towards its heavenly element; it quickly expires and dies if it lies idle. Wherefore if we would keep it alive, we must nourish it, and blow it up by frequent acts of love; and those not mere verbal acts, by telling God that we love him, whilst our heart perhaps is far from him, but by the real exercise of loving God both in our heart and in our works. We exercise the love of God in our heart, by affection; we exercise the love of God in our works, by effects. We love God with a love of chaste concupiscence, when in heart and work we tend to him as our sovereign good, and aspire after the eternal enjoyment of him. We love him with a love of benevolence, that is of sincere and perfect friendship and charity, when both in heart and work we give our whole selves, with all our thoughts, words, and deeds, and all things else to him, as being infinitely good in himself. It is just we should exercise ourselves in acts of the love of God in both these ways, as in both these ways he is infinitely amiable but more especially that we should tend to love him with the love of benevolence, by giving ourselves and all things to him.

Consider 2ndly, that benevolence is a love by which we wish all manner of good to the person beloved; a love by which we earnestly seek and procure whatever may be for his honor, interest, or pleasure; by which we delight in all his advantages, and are concerned at all his losses, &c. Wherefore, if we would make proper acts of the love of benevolence towards God, we must desire, seek, and procure, as much as lies in us, the greater honor and glory of his name, and the propagation of his kingdom, both in our own hearts and throughout the whole world, and pray that all men may know him, love him, and serve him; we must rejoice at every thing that is agreeable to his holy will, and be concerned at every thing that offends him. This is the proper exercise of the love of benevolence; these are far better acts of divine charity than merely telling God that we love him. My soul, what are thy dispositions? Dost thou sincerely desire and heartily pray that all the world may know, love, and serve thy God; that all his creatures in heaven and earth may give perpetual glory to him; that the reign of sin may be abolished; and that the kingdom of God may take possession of all hearts; that none may resist or rebel against his orders; but that all may embrace and bow down, and adore his divine will? If so, there is no doubt but thou lovest God. Such as these are perfect acts of the love of God.

Consider 3rdly, that the exercise of the love of God, which, above all others, is recommended in holy Scriptures, is the loving of his divine law and the keeping of his commandments. 'This is the charity (that is the love) of God that we keep his commandments,’ 1 John v. 3. ‘He that keepeth his word, in him, in very deed, the charity of God is perfected,’ chap. ii. 5. The beloved disciple continually recommends acts of this kind of divine love, and the Psalms are full of aspirations or breathings of a soul that is in love with the holy law and commandments of God. This devotion to the commandments of God is loving God indeed with a true and effectual love, because it is giving up for his sake what is most dear to us, viz., our own will and liberty, and making a present of it to him; it is giving him what he chiefly calls for at our hands; whatsoever else we give him can never content him. He always prefers the sacrifice of obedience before all other sacrifices, because here we sacrifice to him our own clear will, and immolate it, as it were, to his honor and glory. This kind of love is the safest from illusions, for whosoever loves the commandments of God and his divine will, and makes all that is in him submit thereunto, most certainly loves God, and is in the right way that will bring bins safe to God. No other devotion without this can secure any man.

Conclude to exercise thyself daily in all these ways of loving God, and ever remember that loving God and keeping his commandments go always hand-in-hand, because we cannot love God without loving his will, notified to us by his commandments."

Today is the beginning of three days of prayers and fasting that were traditionally known as Rogation Days. Below you will find historical information I gathered from different sources:
"Monday, Tuesday, and Wednesday before Ascension Thursday were instituted by the Church to appease God's anger at man's transgressions, to ask protection in calamities.

These Rogation Days are of French origin, coming about in the 5th c., when St. Mamertus, Bishop of Vienne, Dauphiné instituted them after a series of natural calamities. Rogation is simply an English form of the Latin rogatio, which comes from the verb rogare, which means "to ask". The Rogation Days were marked by the recitation of the litany of the Saints which would normally begin in or at a church.
After Saint Mary was invoked, the congregation would proceed to walk the boundaries of the parish, while reciting the rest of the litany (and repeating it as necessary or supplementing it with some of the penitential or gradual Psalms). Thus, the entire parish would be blessed, and the boundaries of the parish would be marked. The procession would end with a Rogation Mass, in which all in the parish were expected to take part.

If your parish does not celebrate the Rogation Days, there's nothing to stop you from celebrating them yourself. You can mark the days by reciting the Litany of the saints.
We could also pray the Litany to obtain Holy Priests:
Finish it all off by attending daily Mass and praying for good weather and a fruitful harvest."

On the Means of Attaining the Love of God

"Consider first, that as the desire of wisdom is the true beginning of wisdom, so the first step to the love of God, (which is true wisdom indeed,) is an earnest desire to love God. ‘Blessed are they that hunger and thirst after this heavenly justice, for they shall be filled,’ Matt. v. This desire makes us pray frequently, seek incessantly, knock earnestly at the gate of divine love. It makes us rise early in quest of the heavenly wisdom; it makes us glad to part with all things else, that we may purchase this precious pearl, that we may acquire this incomparable treasure. He that with this desire aspires after divine love, already begins to possess what he desires; and the more he relishes the sweetness of what he begins to possess, the more he aspires after it. Thus the desire of love begets love, and love begets a stronger desire, which begets a stronger love. So that the great means of learning to love God is, by repeated desires and acts of love to taste and see how sweet God is, and how sweet a thing it is to love.

Consider 2ndly, that divine love will not be found by us, nor come to dwell in our souls, if we take no care to keep our inward house clean and pure for our beloved. ‘Blessed are the clean of heart, for they shall see God,’ Matt. v. So that if we entertain in our interior any irregular company, that is, if our affections are set upon worldly vanities, upon filthy lucre, upon sensual pleasures, upon gratifying our corrupt inclinations, divine love will not come near us; because it cannot endure such unclean company as this is, nor dwell in a soul that is enslaved to worldly desires and disorderly passions. These are to be parted with, or at least brought into order and subjection, if we would learn to love God. This is the meaning of that Gospel lesson of selling all to acquire the precious pearl of the kingdom of God, by his love reigning in our souls. The kingdom of divine love will allow of no rival, no usurper, no rebel in its dominions. The spouse of divine love must belong wholly to her spouse alone, she must be a garden close shut to all others, a ‘fountain sealed up’ for him alone, Canticle. iv. So that another necessary means of attaining divine love is a general mortification of all foreign and irregular affections.

Consider 3rdly, that the sovereign means of acquiring divine love is the daily exercise of mental prayer, which employs all the powers of the soul in waiting upon God. Here the memory represents all the motives we have to love him; here the understanding is taught to know him; here the affections of the will are inflamed by his presence - this then is the true school of love. O my soul, let us daily frequent it, not only by having a regular time fixed for this great exercise of love, but by practicing it in some measure at all times, by a spirit of recollection, by a continual sense and remembrance of God’s presence, by frequently calling back the soul to him from all her distractions and evagations, by repeated aspirations and ejaculations of love, &c. This is walking with God indeed, like the ancient saints this is taking God along with us wherever we are going, and whatever we are doing; this is walking in love. O how happy is that life which is thus dedicated to divine love.

Conclude to embrace all the means that may bring thee to this happiness. O begin now from this hour to set out in quest of this fountain of life! Let no opposition of earth or hell discourage thee. Never leave off thy search till thou come to drink of this heavenly water, which will become in thee a fountain springing up to everlasting life."

Meditation by Bishop Challoner:

Rogation Sunday on the Devotion of the Time:

  " Consider first, that these days, between this Sunday and the ascension of our Lord, are days of devotion, and are called rogation-days, because they are set aside by the church for solemn prayers and supplications, joined with abstinence and penance, in order to turn away the wrath of God, provoked by our sins; and to remove far from us his scourges of wars, plagues, famines, &c.; to implore his mercy for ourselves, and for all his people; and to beg his blessing upon the fruits of the earth. As the first institution of the devotion of these days was occasioned by a terrible scene of disasters and visible judgments of God upon the people, to which a stop was put by dedicating these three days to prayer and penance; so the success that attended this first essay has encouraged the church to an annual practice of the like devotion ever since. Hence we may learn, with what dispositions of soul we ought to present ourselves before the throne of grace at this time; with what a lively sense of the guilt of our sins, and of the judgments we deserve for them both here and hereafter; with what desire to return to God from our sins, and to offer him the sacrifice of a contrite and humble heart for them, and to join, as it were in a body, at this time, with the whole people of God, in suing in a proper manner for his mercy, with most humble supplication and fervent prayers. See, my soul, if these be thy dispositions.

   Consider 2ndly, that although we do not every day feel the heavy hand of divine justice by the experience of public calamities, or other visible judgments, yet if we consider the guilt of so many crying sins, not only of particular persons, but even of whole nations, which are continually calling to God for vengeance, we shall find too much reason to apprehend that the sword of God’s justice is even now hanging over our heads and that the worst of his judgments will quickly fall upon Christendom in general, if not averted by prayer and penance. This consideration ought to determine all Christians in general (even the most innocent, if they have any concern for the public danger, or true charity for the souls of their neighbors,) gladly to embrace so happy an opportunity as this of joining with all the children of God in humiliations and prayer, in order to prevent the thunder of heaven from suddenly breaking over our heads, and hurrying away thousands into the bottomless pit. And as for every particular sinner, now is the most favorable time for him to sue for mercy, because at this time the whole church joins in a particular manner in praying for all sinners. And if he should neglect this opportunity, what may he not justly fear from his repeated treason; from the wrath of God above, ready to fall upon him; from the mouth of hell below, gaping to devour him; from the devil, to whom he has sold himself; and from that monster, mortal sin, (which is even worse than the devil,) which he always carries about with him? O sinners, neglect not these days of salvation, lest they never return to you any more. Now is your time - hereafter there may be no time for you.

Consider 3rdly, she encouragement we have both in the Epistle and the Gospel of the Rogations, to look for mercy and for all good, both for ourselves and for our neighbors, from humble and fervent prayer. In the epistle (St. James v.) we are taught the great efficacy of continual prayer, with an exhortation to pray for one another, in order to salvation and a declaration of what the reward will be of them that contribute to the salvation of others. In the gospel (St. Luke xi.) we are exhorted by Christ our Lord to a holy importunity and perseverance in prayer; and we are taught by the example of a friend, and of a father, to look for good gifts from our heavenly Father by the means of earnest prayer. O what a friend indeed, what a parent have we in him! or who is like to him in bounty and mercy? Let us then be encouraged by these divine oracles, ‘To go with confidence at this time to the throne of grace, that we may obtain mercy, and find grace in seasonable aid.’ Heb. iv. i6.

   Conclude to join at this time with the whole church of God in prayer and penance, that thou mayest obtain mercy both for thyself and for thy neighbors. Heaven can never resist a general assault made by the whole people of God by the means of prayer, when joined with a contrite and humble heart."

Offering of the Holy Face

    Oh, my beautiful Immaculate Mother Mary, Queen of Sorrows, I beg of you, by the inexpressible agony you did endure at the foot of the Cross, to offer to the Eternal Father, in my stead, the Holy Face of your Divine Son, my Jesus, covered with Blood, wounds, and other indignities heaped upon Him during His Sacred Passion, and beg of Him to grant … (Here mention the grace or favor you desire). Amen. (by St. John Vianney, The Curé of Ars)

Prayer to Obtain the Settlement of all Our Needs

" Oh, Eternal Father, since it has pleased our Divine Savior to reveal to mankind in our present century the power residing in His Holy Face, we now avail ourselves of this treasure in our great needs. Since our Savior Himself promised that by offering to You, oh Eternal Father, the Holy Face disfigured in the Passion, we can procure the settlement of all our affairs, and that nothing whatsoever will be refused us, we now come before Your Throne.

    Offering to You, oh God, this adorable Countenance, disfigured with painful bruises and covered with shame and confusion, we beg through the merits of this Holy Face to obtain these, our pressing needs.

    Grant us pardon, Eternal Father, for the worst crimes of our age, which are atheism, blasphemy, and the desecration of Your holy days. May this offering of the Holy Face of our Savior before Your throne obtain for us deliverance from these evils.

    Send us, oh God, many vocations to the priesthood and to the religious life, so that by their prayers, their works, and their sacrifices, they may spread the blessings of Your Church and confound Your enemies. Amen."

Divine Savior Jesus Christ, Thou are the Good Shepherd who gives His life for His sheep. Oh, be in a very special way the Good Shepherd of those poor lost priests who are also appointed by Thee to be leaders of Thy people, but who have broken the oath of their holy ordination and have become unfaithful to their exalted calling. Bestow upon these poorest of the poor the very fullness of that pastoral solicitude with which Thou dost so faithfully seek the sheep that are lost! Touch their hearts with the irresistible ray of grace which emanates from Thine all-merciful love! Enlighten their minds and strengthen their wills, that they may turn away from all sin and error and come back to Thy holy altar and to Thy people. O most compassionate Savior! Remember that Thou didst once redeem the souls of Thine erring priests with Thy Precious Blood and in infinite preferential love didst impress upon them the indelible character of the priesthood. Put wholly to shame those miserable helpers of Satan who lay snares for the virtue of priests and endanger the holy ideal of the priesthood. Most graciously accept our prayers and sacrifices for poor priests who have gone astray and hear our earnest petition. Amen
