In his Apostolic Letter on the "Rosary of the Virgin Mary"
(Rosarium Virginis Mariae), published on Oct. 16, 2002, Pope John
Paul II gave us five new mysteries of the Rosary, the Mysteries of
Light, or the Luminous Mysteries. He explained in paragraph
19:
In the course of those mysteries we contemplate important aspects
of the person of Christ as the definitive revelation of God.
Declared the beloved Son of the Father at the Baptism in the
Jordan, Christ is the one who announces the coming of the Kingdom,
bears witness to it in his works and proclaims its demands. It is
during the years of his public ministry that the mystery of Christ
is most evidently a mystery of light: "While I am in the world, I
am the light of the world" (John 9:5).
Knowing that He would soon ascend to heaven, Jesus passed these
mysteries onto us (cf. Matthew 5:14-16). He said:
"You are the light of the world. A city set on a mountain cannot be
hidden. Nor do they light a lamp and then put it under a bushel
basket; it is set on a lampstand, where it gives light to all in
the house. Just so, your light must shine before others, that they
may see your good deeds and glorify your heavenly Father."
The pope, in quoting Blessed Bartolo Longo (see para. 15), inspires
us to remember as we pray through the mysteries of the life of
Christ that the Rosary should transform us, conforming us more into
the likeness of Christ. The mysteries of the Rosary describe our
own spiritual journey:
"Just as two friends, frequently in each other's company, tend to
develop similar habits, so too, by holding familiar converse with
Jesus and the Blessed Virgin, by meditating on the mysteries of the
Rosary and by living the same life in Holy Communion, we can
become, to the extent of our lowliness, similar to them and can
learn from these supreme models a life of humility, poverty,
hiddenness, patience and perfection". (I Quindici Sabati del
Santissimo Rosario, 27th ed., Pompei, 1916, 27.)
Therefore, this Rosary for the Conversion of the World, includes
prayers and scriptures that will lead us on the journey of
holiness, burning out our impurities with the flame of Christ so
that He shines more brightly within us. The conversion of the world
occurs one person at a time, beginning with each one of us who take
this prayer seriously. As the light of Christ within us glows
brighter, the darkness in the world around us diminishes.
Gradually, our world is consumed by Christ. It starts with us and
spreads. As we are converted by meditating on and learning from the
life of Christ, so too is the world converted.
Please also pray this Rosary to intercede for others, significantly
for those you know who need the light of Christ to drive out their
darkness, and likewise for the whole world. As Pope John Paul II
wrote in his apostolic letter:
"The Church has always attributed particular efficacy to this
prayer, entrusting to the Rosary ... the most difficult problems.
At times when Christianity itself seemed under threat, its
deliverance was attributed to the power of this prayer, and Our
Lady of the Rosary was acclaimed as the one whose intercession
brought salvation." (para. 39)
