1. The joys and the hopes, the griefs and the anxieties of the men of this age, especially those who are poor or in any way afflicted, these are the joys and hopes, the griefs and anxieties of the followers of Christ. Indeed, nothing genuinely human fails to raise an echo in their hearts. For theirs is a community composed of men. United in Christ, they are led by the Holy Spirit in their journey to the Kingdom of their Father and they have welcomed the news of salvation which is meant for every man. That is why this community realizes that it is truly linked with mankind and its history by the deepest of bonds.
2. Hence this Second Vatican Council, having probed more profoundly into the mystery of the Church, now addresses itself without hesitation, not only to the sons of the Church and to all who invoke the name of Christ, but to the whole of humanity. For the council yearns to explain to everyone how it conceives of the presence and activity of the Church in the world of today.
