Marie de Nazareth
To Jesus, through Mary
19. Of the many mysteries of Christ's life, only a few are indicated by the Rosary in the form that has become generally established with the seal of the Church's approval. The selection was determined by the origin of the prayer, which was based on the number 150, the number of the Psalms in the Psalter.
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 pattern which, while left to the freedom of individuals and communities, could broaden it to include the mysteries of Christ's public ministry between his Baptism and his Passion. 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” (Jn 9:5).
Consequently, for the Rosary to become more fully a “compendium of the Gospel”, it is fitting to add, following reflection on the Incarnation and the hidden life of Christ (the joyful mysteries) and before focusing on the sufferings of his Passion (the sorrowful mysteries) and the triumph of his Resurrection (the glorious mysteries), a meditation on certain particularly significant moments in his public ministry (the mysteries of light). 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 the depths of the Heart of Christ, ocean of joy and of light, of suffering and of glory.
