294 Christ called twelve apostles (meaning those who are sent). Upon them he founded the Church and sent them into the world to preach the Gospel: “He called to him those whom he wanted, and they came to him. And he appointed twelve, whom he also named apostles, to be with him, and to be sent out to proclaim the message” (Mk 3:13-14). The apostolic ministry continues in the ministry of the Church hierarchy and in the apostolate (mission) of all the faithful. “The Church, though dispersed throughout the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith … [and] carefully preserves it … proclaiming and teaching them … with perfect harmony, as if she possessed only one mouth.”249 For this reason, in the Symbol of Faith we profess the Church of Christ to be apostolic. The apostolicity of the Church is realized in the ministry of bishops, priests, deacons, monastics, and laity, who work together for the sake of salvation of the whole world.
