Okay, I'll bite. I just have a simple question. What are Rosary beads, what are they supposed to do, and what is a Rosary?
I was born and raised Protestant, lol.
The Rosary developed out of the laity's desire to have a form of prayer similar to that practiced by monks, who prayed the Book of Psalms. The mostly illiterate laity, began the practice of saying 150 Hail Marys in place of the psalms. Some used a string of 150 beads to keep count. With time, mysteries from the life of Christ were added to allow for contemplation and to keep Christ as the central focus of the prayer.
The Rosary took its present form between the 14th and 15th centuries, when a monk divided the 150 Hail Marys into the 15 decades, with each decade preceded by the Our Father. In 1569, Pope Pius V officially approved and recommended this prayer for all in the Church. From that time to the present, the Rosary remained unchanged.
In October 2002, Pope John Paul II added a new set of Mysteries to the Rosary—the Mysteries of Light. The Rosary now consists of four sets of mysteries, or 20 decades, or 200 Hail Marys. The Pope made this change so that the mysteries would span the entire lives of Christ and Mary, and
therefore the Rosary would become a complete summary of the entire Gospel.
The Rosary as Prayer
As Gospel prayer
The rosary is rooted in Scripture, especially in the Gospel. The Apostles' Creed, which begins the Rosary, is a summary of the mysteries of Faith, which are standard Gospel teachings. Each decade is preceded by the Our Father, a prayer straight out of the Gospel and taught to us as a model of prayer by Jesus.
The first part of the Hail Mary is composed of verses from the Gospel of Luke (1:28 and 1:42): the angel's words announcing Christ's birth and Elizabeth's greeting to Mary. Both of these Gospel passages point to the central mystery of our faith, the incarnation of the Messiah.
Mary's key role in the mystery of Christ is not a rosary invention. Rather, it is a vital part of the Gospel that is simply reflected in this form of prayer. The sense that the rosary is a prayer of confidence in Mary's love and intercession for us is rooted in the Good News of the Gospel. The Gospel passages from which the Hail Mary were drawn, moreover, reveal Mary as a dynamic, grace-filled woman to whom God offered a pivotal and active role in the drama of salvation.
As Christ-centred prayer
At some point in history, the name of Jesus was added to the first part of the Hail Mary, indicating that all that precedes it can be fully understood only in the person of Christ. Jesus, the fruit of the Virgin's womb, is truly the center and summit of this prayer.
The mysteries of the rosary are clearly centered on events in Christ's life, the joyful mysteries on his incarnation, the luminous mysteries on his ministry and revelation of himself to the world, the sorrowful mysteries on his suffering and death, and the glorious mysteries on his resurrection.
On one occasion, Pope Paul VI held up his rosary and proclaimed: "This is the Bible for those who can neither read nor write." The whole history of our salvation is contained in these mysteries which summarize the life of Christ.
The mysteries of Christ and Mary do not simply refer to past events. Christ truly lives among us now, continuing to be born, to suffer, die and rise again in the Church of our day. When we pray, "Blessed is the fruit of thy womb, Jesus," we need to remember that we, too, the body of Christ, are also the fruit of her womb, for we are born of the Christ who was born of Mary. Mary is not only the Mother of Christ, but also the Mother of the Church.
As ‘incarnational’ prayer
The God of Christians is not an abstraction but a personal God who "was born of the Virgin Mary" and who walked with us as a fellow human in this world.
"Abstractions do not require mothers!" as theologian Karl Rahner has been quoted as saying. On the other hand, we know that Jesus Christ, the central figure of the rosary, did "require" a mother. We are reminded of the realness, humanness and accessibility of our loving God each time we pray the rosary.
As an aide for contemplation
The rosary is meant to be a prayer that leads us to Christ and into union with God. If it only locks us into a meaningless circle of mechanically recited prayers, the rosary is not achieving its purpose.
The words of the rosary are meant to launch us into the mysteries of Christ's life or, better, into the living mystery of Christ himself. Just as each Hail Mary builds up to the word Jesus, so the whole rosary leads to union with him, and through Jesus we come into union with God. Each decade ends with a Glory Be, suggesting that the whole rosary is a movement toward praise and joyful union with God.
In praying the rosary, it's important not to get too tied down or worried about the words, at least, not to get anxious about them. It you feel inspired to savour the words and their meaning, fine. There is a scriptural richness and a spiritual energy to be tapped from the words themselves. But don't hesitate to soar beyond the words to the mysteries of Christ or into the loving presence of God.
It is not necessary to focus on the words; more important is to pray from the heart. Many people who say the rosary consider the words to be like background music leading them more deeply into the mysteries or into God's loving presence within. The gentle murmur of the words, for example can take us into that silent centre in us where the Spirit dwells.
The use of repetition for contemplation is an ancient practice. Repeating a sacred word or verses of Scripture, in rhythm with one's breathing, is a method of contemplative prayer described by early Christian writers and which survives today in various forms of centering prayer. Just as the repetition of words and breathing can lead to a contemplative state, so too can the soothing repetition of touch. The use of beads brings the sense of touch into the act, making the rosary a prayer of the body as well as of the mind. It's also a way of bringing creation itself (wood, metal, etc.) into the service of God, it is a very incarnational way of praying.
