Papal reflections of the Mysteries

The Joyful Mysteries:

are marked by the joy radiating from the event of the Incarnation. This is clear from the very first mystery, the Annunciation, where Gabriel's greeting to the Virgin of Nazareth is linked to an invitation to messianic joy: "Rejoice, Mary." The whole of salvation … had led up to this greeting. 
(Prayed on Mondays and Saturdays, and optional on Sundays during Advent and the Christmas Season.)

The Sorrowful Mysteries:

The Gospels give great prominence to the Sorrowful Mysteries of Christ. From the beginning, Christian piety, especially during the Lenten devotion of the Way of the Cross, has focused on the individual moments of the Passion, realizing that here is found the culmination of the revelation of God's love and the source of our salvation.
(Prayed on Tuesdays and Fridays, and optional on Sundays during Lent.)

The Glorious Mysteries:

"The contemplation of Christ's face cannot stop at the image of the Crucified One. He is the Risen One!" The Rosary has always expressed this knowledge born of faith and invited the believer to pass beyond the darkness of the Passion in order to gaze upon Christ's glory in the Resurrection and Ascension. … Mary herself would be raised to that same glory in the Assumption.
(Prayed on Wednesdays and Sundays.)

From the Apostolic Letter The Rosary of the Virgin Mary, Pope John Paul II, Oct. 16, 2002.

The wording of the Hail Mary and the Apostles' Creed complies with the U.S. Conference of Catholic Bishops.

The Luminous Mysteries:

Moving on from the infancy and the hidden life in Nazareth to the public life of Jesus, our contemplation brings us to those mysteries which may be called in a special way "mysteries of light." Certainly, the whole mystery of Christ is a mystery of light. He is the "Light of the world" (John 8:12). Yet this truth emerges in a special way during the years of His public life.
(Prayed on Thursdays.)
