When we penetrate by means of the continually and rapidly increasing experience of the human family into the mystery of Jesus Christ, we understand with greater clarity that there is at the basis of all these ways that the Church of our time must follow, in accordance with the wisdom of Pope Paul VI86, one single way: it is the way that has stood the test of centuries and it is also the way of the future. Christ the Lord indicated this way especially, when, as the Council teaches, "by his Incarnation, he, the Son of God, in a certain way united himself with each man"87. The Church therefore sees its fundamental task in enabling that union to be brought about and renewed continually. The Church wishes to serve this single end: that each person may be able to find Christ, in order that Christ may walk with each person the path of life, with the power of the truth about man and the world that is contained in the mystery of the Incarnation and the Redemption and with the power of the love that is radiated by that truth. Against a background of the ever increasing historical processes, which seem at the present time to have results especially within the spheres of various systems, ideological concepts of the world and regimes, Jesus Christ becomes, in a way, newly present, in spite of all his apparent absences, in spite of all the limitations of the presence and of the institutional activity of the Church. Jesus Christ becomes present with the power of the truth and the love that are expressed in him with unique unrepeatable fullness in spite of the shortness of his life on earth and the even greater shortness of his public activity.
Jesus Christ is the chief way for the Church. He himself is our way "to the Father's house"88 and is the way to each man. On this way leading from Christ to man, on this way on which Christ unites himself with each man, nobody can halt the Church. This is an exigency of man's temporal welfare and of his eternal welfare. Out of regard for Christ and in view of the mystery that constitutes the Church's own life, the Church cannot remain insensible to whatever serves man's true welfare, any more than she can remain indifferent to what threatens it. In various passages in its documents the Second Vatican Council has expresscd the Church's fundamental solicitude that life in "the world should conform more to man's surpassing dignity"89 in all its aspects, so as to make that life "ever more human"90. This is the solicitude of Christ himself, the good Shepherd of all men. In the name of this solicitude, as we read in the Council's Pastoral Constitution, "the Church must in no way be confused with the political community, nor bound to any political system. She is at once a sign and a safeguard of the transcendence of the human person"91.
