Prayers to the Blessed Virgin Mary

 St. Catherine of Siena

O Mary, Redemptress of Humankind, because by your flesh suffering in the Word, the world was redeemed: Christ redeemed it by His Passion and you by pain of body and spirit. I have recourse to you, Mary, and I offer you my prayer for the Sweet Bride of Christ and for His Vicar on earth. May the people be united and their hearts conformed to His.
Prayer XI

In you, O Mary, our human strength and freedom are revealed today…The Angel was sent to you to announce the Mystery of the Divine Counsel and to seek to know your will; and God’s Son did not come down into your womb until you had given your will’s consent. He waited at the door of your will for you to open to Him: for He wanted to come into you, but He would never have entered unless you had opened to Him, saying, “Here I am, God’s servant; let it be done to me as you have said.”
Feast of the Annunciation. 

O Mary, Vessel of Humility, in which stays and burns the light of true knowledge, with which you lifted yourself above yourself; and therefore you were pleasing to the Eternal Father so He grasped you and drew you to Himself, loving you with a special love; with this light and the fire of your charity and with the oil of your humility, you drew and bent down His divinity to come into you, although first He was drawn by the most blazing fire of His inestimable charity to come to us.
Prayer XI

O Mary, my sweetest love! In you is written the Word from Whom we have the teaching of life. You are the tablet which offers us that teaching. I see this Word, even as soon as He was written in you, He was not without the cross of holy desire. Immediately when He was conceived in you, the desire to die for the salvation of humanity, for which He was incarnated, was grafted and attached to Him. So it was a great cross to Him, to bear that desire so much time when He would have wished that it might be fulfilled at once.
Prayer XI 

Today I ask boldly because it is the day of graces and I know that to you, Mary, nothing is denied. O Mary, today your earth has sprouted a Savior to us. O Mary, blessed are you among all the women of the ages, for today you have given us of your flower. Today, the Godhead is united and kneaded with our humanity so strongly that this union is never able to be separated neither through death nor through our ingratitude. Rather, the Godhead was always united, even with the Body in the sepulcher and with the Soul in limbo...
Prayer XI

You, O Mary, are made a book in which today is written our rule. In you today is written the wisdom of the Eternal Father. In you is manifest today the strength and freedom of humanity. I say that it shows the human dignity because if I look in you, Mary, I see that the hand of the Holy Spirit has written in you the Trinity, forming in you the Word Incarnate, the only-begotten Son of God…O Mary, I see this Word given to you to be in you, and not the less was He separated from the Father, just as the word which a person has in the mind, although it is uttered outside and communicated to others, it does not leave nor is it separated from the heart.
Prayer XI

St. Thomas Aquinas

O most blessed and sweet Virgin Mary, Mother of God, filled with all tenderness, daughter of the most high King, Lady of the Angels, Mother of all the faithful, on this day and all the days of my life, I entrust to your merciful heart my body and my soul, all my acts, thoughts, choices, desires, words, deeds, my entire life and death, so that, with your assistance, all may be ordered to the good according to the will of your beloved Son, our Lord Jesus Christ. Be to me, my most holy Lady, a comforter and an ally against the stratagems and traps of the ancient enemy and of all those who harbor ill intentions against me. From your beloved Son, our Lord Jesus Christ, request for me the grace to resist firmly the temptations of the world, the flesh, and the devil, and a constant resolve to sin no more and to persevere in your service and the service of your beloved Son. My most holy Lady, I also beseech you to obtain for me true obedience and true humility of heart so that I may recognize myself truly as a sinner—wretched and weak—and powerless, without the grace and help of my Creator and without your holy prayers, to do any kind of good work or even to resist the unrelenting assaults of evil. Procure for me also, O my most sweet Lady, perpetual purity of mind and body, so that with a pure heart and chaste body I may be strengthened to serve you and your beloved Son through the Dominican Order. From Him, obtain for me a spirit of poverty willingly accepted with patience and tranquility of mind, so that I will have the strength to sustain the labors of this Order and to work for my own salvation and that of my neighbors. Obtain for me as well, O most sweet Lady, true charity with which from the depths of my heart I may love your most holy Son, our Lord Jesus Christ, and, after Him, love you above all other things, and love my neighbor in God and because of God. Thereby may I rejoice in his goodness, sorrow over his evils, despise no one, never judge rashly, and never in my heart exalt myself over anyone. Grant, O Queen of Heaven, that ever in my heart I may have fear and love alike for your most sweet Son; that I may always give thanks for the many blessings bestowed upon me not for my merits but by His kindness; and that I may ever make a pure and sincere confession and do true penance for my sins, in order that I might deserve to obtain His mercy and grace. I pray also that, at the end of my life, you, Mother without compare, Gate of Heaven, and Advocate of sinners, will not allow me, your unworthy servant, to stray from the holy Catholic faith but that you will protect me with your great piety and mercy, defend me from evil spirits, and obtain for me, through the blessed and glorious Passion of your Son and through your own intercession, received in hope, the forgiveness of all of my sins. When I die in your love and His love, may you direct me into the way of salvation and blessedness. Amen.
