Pope Benedict encourages everyone to have devotion to a particular saint, maybe our namesake.
The Holy Father said that it is important "to have 'travel companions' on the journey of our Christian life: I am thinking of a spiritual director, a confessor, persons with whom we can share the experience of faith, but I am also thinking of the Virgin Mary and of the saints."(See Zenit for further details.)
"Each one," he said, "should have a saint that is familiar to him, to whom he feels close with prayer and intercession, but also to imitate him or her. Hence, I would like to invite you to know the saints better, beginning with the one whose name you bear, by reading his life, his writings. You can be certain that they will become good guides to love the Lord ever more and valid aids for your human and Christian growth."
Many people now do not have names that have any reference to saints. It used to be the case that Christians were given a saint's name or names at Baptism, and would take another saint at Confirmation. But names like 'Autumn', 'Bristol', 'Chelsea' while not being in any way anti-Christian and therefore not contrary to the provisions concerning batismal names contained in the Code of Canon Law, do not, I feel, help children to grow up with the idea of seeking the protection of a particular saint, or seeking to imitate the example of that saint.
I happen to know that I was named after St John the Evangelist and I therefore have particular devotion to the Beloved Disciple. My second baptismal name is Joseph, and therefore St Joseph is a particular friend of mine. I chose Francis of Assisi to be my confirmation patron. I have no doubt that these saints have helped me considerably throughout my life.
Maybe parents should be encouraged to always give a saint's name to their child immediately when they are born and these names be registered on the birth certificate. It's always a bit awkward suggesting a saint's name when the birth certificate has already been issued.
