The First Luminous Mystery- the Baptism of Jesus

The Luminous Mysteries were added to the Rosary by Pope John Paul II ( the Great) in 2002. They fill inthe gap between the Joyful and the Sorrowful Mysteries.  A little different in character than the original ( Joyful, Sorrowful, Glorious) mysteries in that they are not seen through Mary's eyes, they still keep the tradition of eventsin the life of Jesus Christ in which we see God at work, though we may not fully understand how or why.

First Luminous Mystery: The Baptism of Jesus. (MK 1 :1-11, also in other gospels) It seems ridiculous, doesn't it? John preached a baptism of repentance, Jesus had no sin to repent of. But- as 

in all things- Christ set the example for us through his own baptism. The CCC says this about Jesus's baptism:

537 Through Baptism the Christian is sacramentally assimilated to Jesus, who in his own baptism anticipates his death and resurrection. The Christian must enter into this mystery of humble self-abasement and repentance, go down into the water with Jesus in order to rise with him, be reborn of water and the Spirit so as to become the Father's beloved son in the Son and "walk in newness of life."

In this mystery we learn obedience and how to begin to conform our own lives to that of Christ.
