“Go into all the world and preach the gospel to the whole creation” (Mk 16:15); “make disciples of all nations” (Mt 28:19). With these words, Jesus sends the Apostles to all creation, so that God’s saving action may reach everywhere. But if we consider the moment of Jesus’ ascension into heaven, as recounted in the Acts of the Apostles, we see that the disciples are still closed in their thinking, looking to the restoration of a new Davidic kingdom. They ask the Lord: “will you at this time restore the kingdom to Israel?” (Acts 1:6). How does Jesus answer? He answers by broadening their horizons and giving them both the promise and a task: he promises that they will be filled with the power of the Holy Spirit, and he confers upon them the task of bearing witness to him all over the world, transcending the cultural and religious confines within which they were accustomed to think and live, so as to open themselves to the universal Kingdom of God. At the beginning of the Church’s journey, the Apostles and disciples set off without any human security, purely in the strength of the Holy Spirit, the Gospel and the faith. This is the yeast that spreads round the world, enters into different events and into a wide range of cultural and social contexts, while remaining a single Church. Around the Apostles, Christian communities spring up, but these are “the” Church which is always the same, one and universal, whether in Jerusalem, Antioch, or Rome. And when the Apostles speak of the Church, they are not referring to a community of their own, but to the Church of Christ, and they insist on the unique, universal and all-inclusive identity of the Catholica that is realized in every local church. The Church is one, holy, catholic and apostolic, she reflects in herself the source of her life and her journey: the unity and communion of the Trinity.
