Opening Prayer

How fair are you, O Mary, the original stain is not in you. You are the glory of Jerusalem; you are the joy of Israel, you give honor to our people. You are the advocate of sinners. O Mary, Virgin most prudent, Mother most merciful, pray for us, intercede for us, with the Lord Jesus Christ. Holy Virgin, you were spotless from the very moment of your conception. Because you bore His Son, pray to the Father for us.

O God, who by the Immaculate Conception of the Blessed Virgin prepared a worthy dwelling for your Son, grant, we pray, that, as you preserved her from every stain by virtue of the death of your Son, which you foresaw, so, through her intercession, we, too, may be cleansed and admitted to your presence. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, forever and ever. Amen.

A Reading from the Writings of St. Maximilian Kolbe

"Jesus Christ, Man-God, the true God, the second Person of the Most Holy Trinity, is the true Son of her. She is His true Mother. Keeping the fourth commandment, He honors His Mother: He is her devotee. A son never ceases to be the son of his mother, and so Jesus will be eternally the Son of her, and she will be forever the Mother of Him. He will forever be her devotee. Jesus venerated her from eternity and He shall venerate her for eternity. No one will draw near to Him, will be like Him, will be saved, will be made holy, unless he venerates her: no one, neither angel, nor man, nor other being. She is the Queen of the Universe, Queen of Heaven and earth. In Heaven, they all recognize her as their Queen. Hell detests her and trembles before her, while here on earth, how many souls do not yet know her, or know her too little, or even, making common cause with the demons, do not venerate her but hate her. At all times, in different locations around the globe are born souls, who, all ablaze with the love of her, have kindled such love around them. They came together in order to win hearts over to her more effectively and have consecrated their entire lives to her. (KW 1321)"

Prayer Intention

For the sick and the suffering, in body and spirit, for the lonely and the despairing. Amid mental and physical suffering, may they find consolation in Mary's motherly healing presence. May the Lord close their wounds, cure their illness, make their broken bodies whole and free downcast spirits. May these special people find lasting health and deliverance, and join us in thanking God for all His gifts. Amen.
Our Father...
Hail Mary... 
Glory Be... 
O Mary, conceived without sin, pray for us who have recourse to you, and for all those who do not have recourse to you, especially the enemies of Holy Church and all those recommended to you.

Meditation

The privileges of your Immaculate Conception and divine maternity are inimitable, but you have hidden them within such a simple, humble life that I am not afraid to approach you, and ask you to take me by the hand and help me to ascend the mountain of perfection with you. Yes, you are Queen of heaven and earth; but because you are more Mother than Queen, you encourage me to have recourse to you, saying, “O my child, hear me; blessed are they who keep my ways…. He who finds me, finds life, and will obtain salvation from the Lord” (Roman Breviary). And I answer you in the words of the Church, “Draw me, O Immaculate Virgin, I will run after you in the odor of your ointments” (ibid). - By Dan Burke, in "Solemnity of the Immaculate Conception of the Blessed Virgin Mary" - Roman Catholic Spiritual Direction. 

Closing Prayers

Novena Prayer to the Immaculata
I greet you, ever-blessed Virgin, Mother of God throne of grace, miracle of almighty power! I greet you, sanctuary of the most Holy Trinity and Queen of the universe, Mother of mercy and refuge of sinners! Most loving Mother, attracted by your beauty and sweetness and by your tender compassion, I confidently turn to you, and beg of you to obtain for me of your dear Son the favor I request in this novena (here mention your request).

Obtain for me also, Queen of Heaven, the most lively contrition for my many sins and the grace to imitate closely those virtues which you practiced so faithfully especially humility, purity, and obedience. Above all, I beg you to be my mother and protectress, to receive me into the number of your devoted children, and to guide me from your high throne of glory. Do not reject my petitions, Mother of mercy! Have pity on me, and do not abandon me during life or at the moment of my death.

Daughter of the Eternal Father, Mother of the Eternal Son, Spouse of the Holy Spirit, temple of the adorable Trinity, pray for me. Immaculate and tender Heart of Mary, refuge of the needy and hope of sinners, filled with the most lively respect, love, and gratitude, I devote myself forever to your service, and I offer you my heart with all that I am and all that belongs to me. Accept this offering, sweet Queen of Heaven and earth, and obtain for me of your dear Son, Jesus Christ, the favors I ask through your intercession in this novena. Obtain for me also a tender, generous, constant love of God, perfect submission to his adorable will, the true spirit of a Christian, and the grace of final perseverance. Amen.

Closing Prayer of Identification with the Immaculate
O Immaculate Conception, Mary, my Mother, live in me, act in me, speak in and through me. Think your thoughts in my mind, love through my heart. Give me your own dispositions and feelings. Teach, lead and guide me to Jesus. Correct, enlighten and expand my entire personality and life. Replace me with yourself. Incline me to constant adoration and thanksgiving; pray in and through me. Let me live in you and keep me in this union always. Amen.
