1. For the World Day of Prayer for Vocations, to be celebrated on 13 April 2008, I have chosen the theme: Vocations at the service of the Church on mission. The Risen Jesus gave to the Apostles this command: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit” (Mt 28:19), assuring them: “I am with you always, to the close of the age” (Mt 28: 20). The Church is missionary in herself and in each one of her members. Through the sacraments of Baptism and Confirmation, every Christian is called to bear witness and to announce the Gospel, but this missionary dimension is associated in a special and intimate way with the priestly vocation. In the covenant with Israel, God entrusted to certain men, called by him and sent to the people in his name, a mission as prophets and priests. He did so, for example, with Moses: “Come, - God told him - I will send you to Pharaoh, that you may bring forth my people … out of Egypt …when you have brought forth the people out of Egypt, you will serve God upon this mountain” (Ex 3: 10 and 12). The same happened with the prophets.
