From Rosarium Virginis Mariae
One thing I find interesting is a constant reference to what appears to be "course correction" or "focus" constantly uttered by the Popes to the faithful. In the course of this letter, there must be dozens of references to the Christological aspects of the Rosary. I'm certain all the readers of things like blogs have the "proper" focus when praying the Rosary. However, I know of people for whom that focus is not so clear, and for whom, in fact, the communion of the Saints is not terribly clear. When St. Teresa or St. Anthony obtains something for these people, one gets the impression that the given saint is granting some gift, no matter how carefully worded the petition. If this is rampant in the total communion of Saints, how much more true for that greatest of Saints. The reiteration of the Christological focus of the Rosary is an anodyne to many of the anxieties about it that come from converts from more evangelical or fundamentalist mentalities. While the Rosary opens the opportunity to see Christ through the eyes not only of a loving mother but of his Chief disciple and primary Apostle, it remains intently, narrowly focused on the Life , Mission, Death, and Glories of Jesus Christ.
With regard to the new mysteries of the Rosary, to put everyone at ease, article 19 clearly spells out the Pope's intent in promulgating these:
from Rosarium Virginis Mariae
His Holiness Pope John Paul II
I believe, however, that to bring out fully the Christological depth of the Rosary it would be suitable to make an addition to the traditional lpattern which, while left to the freedom of individuals and communities could broaden it to include the the mysteries of Christ's public ministry between his Baptism and his Passion.
(bold-face emphasis mine)
Thus, clearly delineated for even the most skeptical, our Pope makes clear he is offering new mysteries that do not have to be said. But I know that for me the proposed additions do precisely what the Pope would like them to do , "This addition of these new mysteries, without prejudice to any essential aspect of the prayer's traditional format, is meant to give it fresh life and to enkindle renewed interest in the Rosary's place within Christian spirituality as a true doorway to depths of the Heart of Christ, ocean of joy and of light, of suffering and glory."
