we would like to present ten reasons why we should form the most important habit of praying the Rosary, not sporadically or sometimes or simply upon an impulse. Rather, we should form the habit of praying the Most Holy Rosary of the Blessed Virgin Mary every day; if possible, we could even pray the Rosary more than once a day, as was often the habit in the lives of many of the saints! Therefore, let us launch into reasons to convince us of the dire importance of loving Our Lady by loving what she loves, and obeying her command—pray the Holy Rosary.

1. Our Lady told us to!

If a mother repeats to her child an order many times it is because the mother believes, in the depths of her heart, that the order she is commanding is of great importance. Likewise, the Mother of God and our Mother, Mary most Holy, commanded the children at Fatima, as well as the world at large, six times to pray the Rosary! If it is a command to obey our earthly mothers (the 4th Commandment), how much more should we obey our Heavenly Mother, Mary most Holy!

2. The Rosary is a Biblical prayer.

Many non-Catholics condemn the recitation of the Holy Rosary. However, very few of those who condemn this most beautiful prayer realize or recognize the fact that the Rosary is a prayer that almost totally has its origins in the Word of God itself! For example, the first series of Mysteries that we call the Joyful Mysteries are all of them found in the Gospel of Saint Luke, Chapters One and Two! This being said, we can get to know and love the Word of God by meditating upon the Mysteries of the Holy Rosary!

3. You can learn to know, love, and imitate Christ Jesus.

Saint Ignatius of Loyola, founder of the Jesuits, offers us a fruit that we should beg for when we meditate on or contemplate the life of Jesus; that fruit, or we might call it virtue, is to arrive at intimate knowledge of Jesus, so that we love Him more ardently and follow Him more closely. In a parallel sense, when we form the habit of praying the Rosary well, giving our whole self to entering into the scenes or mysteries of the Rosary, one of the most sublime fruits is the same that Ignatius presents. In praying the Rosary, we get to know Jesus, love Jesus, and desire to follow Jesus through the prayers and intercession of the first disciple of Jesus, His Mother Mary!

4. Summary of the Gospel.

Recent Popes, Blessed Paul VI and Saint John XXIII called the Rosary a summary of the Gospel. This was said even before the insertion of the relatively new mysteries of the Rosary, the Luminous Mysteries. In a short, clear, methodical and systematic form we have the Infancy of Jesus in the Joyful Mysteries; followed by the Luminous Mysteries, which are a good summary of the Public Life of Jesus (30-33 years of age). Then we have the Passion, suffering and death of Jesus in the Sorrowful Mysteries.

Finally, at the summit of the whole prayer, we have the Glorious Mysteries, which of course present Our Lord’s Resurrection and Ascension into heaven, the Coming of the Holy Spirit, and Our Lady’s Assumption into heaven and Coronation as Queen of heaven and earth. As the Popes have alluded to, the contemplation of the mysteries of the most Holy Rosary is a clear and concise summary of the Gospels—the conception, life, death and Resurrection of Jesus seen through the eyes and heart of the Blessed Virgin Mary.

5. The Rosary can lift us to the heights!

The Rosary is indeed a marvelous prayer that can lift us to the heights of holiness if prayed well and with perseverance. This prayer is vocal in that we vocalize the beautiful prayers, the Our Father and Hail Mary. Then it is a meditative prayer in that we reflect upon the meaning of the mysteries and how they can be applied to our own lives right now. Furthermore, it is a contemplative prayer, meaning that we are summoned to enter into the scenes or mysteries of the life of Jesus and Mary.

We are not called to be passive spectators, like going to a movie; rather we are called to enter into these contemplative scenes and be part of the life they lived! If this is done, we become transformed. The saying is true: tell me with whom you associate and I will tell you who you are. How true if we apply this to our frequent association, contact and conversation with Jesus and Mary and Saint Joseph! We will be transformed, becoming more like them. Our desire and goal are the words of the great Apostle Saint Paul:“It is no longer I who lives, but Christ who lives in me.”

6. The Rosary can bring peace of to the world, inner and outer.

In a world in which there is so much tension, fighting, selfishness, and egotism we need a peace-program. Of course the key element is to expel the negative with the most positive, and that is to place Jesus and Mary as King and Queen of our world, country, state, city, home, family, and even our individual lives and hearts! At Fatima, Our Lady insisted that the Rosary be prayed to end World War I and also to prevent another war. Our Lady made the warning that if the world did not pray enough, another and worse world war would erupt. And so it happened!

Sad to say, not many years after the cessation of World War I, the more bloody and gruesome World War II broke out. Sin is due to a lack of the presence of God. The recitation of the most Holy Rosary is the opposite. We invite Jesus into our hearts, families and society through the prayerful, peaceful, but powerful presence of Our Lady, Queen of Peace!

7. A prayer for conquering vices!

Sin can get hold of us, and we become slaves to sin. Jesus Himself says that sin is slavery. A well-known convert once said that before becoming Catholic, he liked going to bookstores to look over the dirty magazines and buy some of them. However, while there, no matter how hard he tried, he could not resist, almost as if he were drawn by a magnet, checking out and browsing through the bad magazines. Though he was still a Protestant, he started to pray the most Holy Rosary, and immediately, his desire to look at the indecent magazines left him totally. He attributed this miracle to the intercession of the Blessed Virgin Mary and the Holy Rosary.

Among the many virtues that Our Lady desires to attain for us is the virtue of purity. One of Our Lady’s messages in Fatima was that most souls are lost for all eternity due to the sins of the flesh, that is to say, sins against the virtue of purity. Jesus expressed this most clearly in one of the Beatitudes:“Blessed are the pure of heart; they will see God.” (Mt 5:8)

8. A prayer for family unity.

One of the most sorrowful realities in the modern world is the breakup of the family unit. Vatican II calls the family the domestic church. Saint Pope John Paul II says “the family is the basic cell of society, and as the family goes, so goes the rest of society.” After the attack on the World Trade Center, Sept. 11, 2001, Pope Saint John Paul II published a spiritual masterpiece with the title Blessed Virgin Mary and the Rosary. We encourage all of our readers to read and meditate upon this spiritual masterpiece so as to get to know and love the most Holy Rosary more and more.

In this papal document, the saintly Pontiff encouraged the world at large to pray the Rosary, but especially for two intentions. First, he exhorted us to pray the Rosary for world peace. Second, he warmly encouraged us to pray the Rosary for the sake and salvation of the family. The Rosary priest, Father Patrick Peyton, expresses this truth in these timely maxims: “The family that prays together, stays together” and, “A world at prayer is a world at peace!” This being said, every family should make a concerted effort to pray the Rosary together for the sake of their own family, as well as for all of the families of the world, and that peace would reign in the world starting first and foremost with our own individual hearts!

9. The Rosary is a spiritual slingshot to conquer the Devil.

In one of the most important meditations in the Spiritual Exercises, with the title The Two Standards, Saint Ignatius presents our spiritual life in the light of a fierce combat between Satan and his disciples fighting against Jesus and His disciples for dominion in our souls! Given today’s materialism, consumerism, hedonism, agnosticism, moral relativism, and militant atheism, the devil can hide behind each of these erroneous philosophical systems to trap us and finally enslave us!

It almost appears as if we are David against Goliath (I Samuel 17)! David was much younger and smaller, with no military preparation, no sword, no shield, nor even any armor. On the other hand, Goliath was a giant, with much experience in battle, wearing armor and wielding a huge crescent sword that he had used to kill many, with a shield bearer preceding him. Goliath curses little David, but David proceeds with confidence in the name of Yahweh, the Lord of Lords and King of Kings. The little shepherd boy approaches the line of battle quickly and resolutely reaches for a stone, places it in his slingshot and launches it at Goliath. The stone takes off like a rocket and rivets itself in the forehead of Goliath, who quickly cascades to the ground.

Today we are surrounded by many Modern Goliaths, as mentioned and named above. Therefore, for us to win the fierce battle, we must place ourselves under the military leadership of the Blessed Virgin Mary, proudly carry our spiritual weapon—the most Holy Rosary, and use it frequently and confidently. We have sure hope with such a weapon and so great a leader that the battle will be won and the victory will be ours!

10. The spiritual treasures stored up in heaven.

One of the greatest saint-mystics in the Catholic Church is Saint Gertrude, the Great. Not only is she the author of the classic Herald of Divine Love (read it!!!), but also she was a great mystic and visionary. Jesus often would appear to her and talk to her with great familiarity and love, as He desires to do with us. On one occasion, the saint saw Jesus in heaven. The scene was beautiful! Bathed in light and beauty, Jesus had a huge pile of coins, shiny and glimmering golden coins. As Saint Gertrude contemplated this scene, Jesus placed another golden coin on the top of the huge pile. Curious as to the meaning of the scene, this great lover of Jesus and Mary, Saint Gertrude, begged the Lord to explain its meaning.

Without any hesitation Jesus said, “I am counting the Hail Marys that you have said; this is the money with which you purchase heaven.” She had just finished another, upon which Jesus deposited another golden coin for all eternity. Hail Marys are the currency of heaven! Saint Louis de Montfort tells us, “Mary is the treasurer of all God’s graces.” Our Lady of Fatima told the children that by praying the Rosary and offering sacrifices, they can merit heaven for themselves and many other souls!

Therefore, if you want to be a multi-billionaire in heaven and save yourself, your loved ones, and many other souls from hell, start right now and pray the Rosary, pray fervently the Hail Marys that compose the Rosary. Indeed, Jesus through the intercession of Mary, who is His Mother, the Mother of the Church, and your loving Mother, will store up for you abundant spiritual treasures in heaven—the salvation of countless souls for all eternity!

Our Lady's 15 Promises for Praying the Rosary
Besides the Indulgences attached to the Rosary, Our Lady revealed to St. Dominic and Blessed Alan de la Roche additional benefits for those who devoutly pray the Rosary. Our Lady's promise is shown in darker blue text. Additional explanation on and doctrinal connections to each promise is shown following in the smaller normal text font and color. Note that the Rosary is the prayer (non-Liturgical) with the most published Magisterial / Papal documents expounding on its excellence. Vatican II's summary on Our Lady is contained in Lumen Gentium chapter VIII.
1.
Whosoever shall faithfully serve me by the recitation of the Rosary shall receive signal graces.
Signal Graces are those special and unique Graces to help sanctify us in our state in life. See the remaining promises for an explanation for which these will consist. St. Louis de Montfort states emphatically that the best and fastest way to union with Our Lord is via Our Lady [True Devotion to Mary, chapter four].
2.
I promise my special protection and the greatest graces to all those who shall recite the Rosary.
Our Lady is our Advocate and the channel of all God's Grace to us. Our Lady is simply highlighting that She will watch especially over us who pray the Rosary. (see Lumen Gentium chapter VIII - Our Lady #62) [a great more detail is available on this topic in True Devotion to Mary, chapter four, by St. Louis de Montfort]
3.
The Rosary shall be a powerful armor against hell, it will destroy vice, decrease sin and defeat heresies.
This promise, along with the next, is simply the reminder on how fervent prayer will help us all grow in holiness by avoiding sin, especially a prayer with the excellence of the Rosary. An increase in holiness necessarily requires a reduction in sin, vice, and doctrinal errors (heresies). If only the Modernists could be convinced to pray the Rosary! (see Lumen Gentium chapter V - The Call to Holiness #42) St. Louis de Montfort states "Since Mary alone crushed all heresies, as we are told by the Church under the guidance of the Holy Spirit (Office of the Blessed Virgin Mary)..." [True Devotion to Mary #167]
4.
It will cause good works to flourish; it will obtain for souls the abundant mercy of God; it will withdraw the hearts of men from the love of the world and its vanities, and will lift them to the desire for Eternal Things. Oh, that souls would sanctify themselves by this means.
This promise, along with the previous, is the positive part, that being to live in virtue. Becoming holy is not only avoiding sin, but also growing in virtue. (see Lumen Gentium chapter V - The Call to Holiness #42)
5.
The soul which recommends itself to me by the recitation of the Rosary shall not perish.
Since Our Lady is our Mother and Advocate, She always assists those who call on Her implicitly by praying the Rosary. The Church reminds us of this in the Memorare prayer, "... never was it known that anyone who fled to your protection, implored your help or sought your intercession, was left unaided ..."
6.
Whosoever shall recite the Rosary devoutly, applying himself to the consideration of its Sacred Mysteries shall never be conquered by misfortune. God will not chastise him in His justice, he shall not perish by an unprovided death; if he be just he shall remain in the grace of God, and become worthy of Eternal Life.
This promise highlights the magnitude of Graces that the Rosary brings to whomever prays it. One will draw down God's Mercy rather than His Justice and will have a final chance to repent (see promise #7). One will not be conquered by misfortune means that Our Lady will obtain for the person sufficient Graces to handle said misfortune (i.e. carry the Crosses allowed by God) without falling into despair. As Sacred Scripture tells us, "For my yoke is sweet and my burden light." (Matthew 11:30)
7.
Whoever shall have a true devotion for the Rosary shall not die without the Sacraments of the Church.
This promise highlights the benefits of obtaining the most possible Graces at the hour of death via the Sacraments of Confession, Eucharist, and Extreme Unction (Anointing of the Sick). Being properly disposed while receiving these Sacraments near death ensures one's salvation (although perhaps with a detour through Purgatory) since a final repentance is possible.
8.
Those who are faithful to recite the Rosary shall have during their life and at their death the Light of God and the plenitude of His Graces; at the moment of death they shall participate in the Merits of the Saints in Paradise.
Our Lady highlights the great quantity of Graces obtain through praying the Rosary, which assist us during life and at the moment of death. The merits of the Saints are the gift of God's rewards to those persons who responded to His Grace that they obtained during life, and so Our Lady indicates that She will provide a share of that to us at death. With this promise and #7 above, Our Lady is providing the means for the person to have a very holy death.
9.
I shall deliver from purgatory those who have been devoted to the Rosary.
Should one require Purgatorial cleansing after death, Our Lady will make a special effort to obtain our release from Purgatory through Her intercession as Advocate.
10.
The faithful children of the Rosary shall merit a high degree of Glory in Heaven.
This promise is a logical consequence of promises #3 and #4 since anyone who truly lives a holier life on earth will obtain a higher place in Heaven. The closer one is to God while living on earth, the close that person is to Him also in Heaven. The Catechism of the Catholic Church states "Spiritual progress tends toward ever more union with Christ." (Catechism of the Catholic Church paragraph 2014)
11.
You shall obtain all you ask of me by recitation of the Rosary.
This promise emphasizes Our Lady's role as our Advocate and Mediatrix of all Graces. Of course, all requests are subject to God's Most Perfect Will. God will always grant our request if it is beneficial for our soul, and Our Lady will only intercede for us when our request is good for our salvation. (see Lumen Gentium chapter VIII - Our Lady #62)
12.
All those who propagate the Holy Rosary shall be aided by me in their necessities.
If one promotes the praying of the Rosary, Our Lady emphasizes Her Maternal care for us by obtaining many Graces (i.e. spiritual necessities) and also material necessities (neither excess nor luxury), all subject to the Will of God of course.
13.
I have obtained from my Divine Son that all the advocates of the Rosary shall have for intercessors the entire Celestial Court during their life and at the hour of death.
Since Our Lady is our Advocate, She brings us additional assistance during our life and at our death from all the saints in Heaven (the Communion of Saints). See paragraphs 954 through 959 in the Catechism of the Catholic Church.
14.
All who recite the Rosary are my Sons, and brothers of my Only Son Jesus Christ.
Since the Rosary is a most excellent prayer focused on Jesus and His Life and activities in salvation history, it brings us closer to Our Lord and Our Lady. Doctrinally, Our Lady is our Mother and Jesus is our Eldest Brother, besides being our God. (see Lumen Gentium chapter VIII - Our Lady #62)
15.
Devotion to my Rosary is a great sign of predestination.
Predestination in this context means that, by the sign which is present to a person from the action of devoutly praying the Rosary, God has pre-ordained your salvation. Absolute certainty of salvation can only be truly known if God reveals it to a person because, although we are given sufficient Grace during life, our salvation depends upon our response to said Grace. (See Summa Theologica, Question 23 for a detailed theological explanation). Said another way, if God has guaranteed a person's salvation but has not revealed it to Him, God would want that person to pray the Rosary because of all the benefits and Graces obtained. Therefore the person gets a hint by devotion to the Rosary. This is not to say that praying the Rosary guarantees salvation - by no means. In looking at promises #3 and #4 above, praying the Rosary helps one to live a holy life, which is itself a great sign that a soul is on the road to salvation. (See also paragraphs 381, 488, 600, 2782 in the Catechism of the Catholic Church.) In fact, St. Louis de Montfort says even more strongly that "an infallible and unmistakable sign by which we can distinguish a heretic, a man of false doctrine, an enemy of God, from one of God's true friends is that the hardened sinner and heretic show nothing but contempt and indifference to Our Lady..." [True Devotion to Mary, #30]
Reminder: these promises mean that, by faithfully and devoutly praying the Rosary, Our Lady will obtain for us the necessary Graces to obtain said promises. It is still up to each individual soul to respond to those Graces in order to obtain salvation.
