Pope Benedict wrote last year,
"A fundamental element, one which can be seen in every vocation ... is friendship with Christ. Jesus lived in constant union with the Father and this is what made the disciples eager to have the same experience; from him they learned to live in communion and unceasing dialogue with God. Prayer is the first form of witness which awakens vocations. Like the Apostle Andrew, who tells his brother that he has come to know the Master, so too anyone who wants to be a disciple and witness of Christ must have “seen” him personally, come to know him, and learned to love him and to abide with him."
