45 While helping the world and receiving many benefits from it, the Church has a single intention: that God's kingdom may come, and that the salvation of the whole human race may come to pass. For every benefit which the People of God during its earthly pilgrimage can offer to the human family stems from the fact that the Church is "the universal sacrament of salvation", simultaneously manifesting and exercising the mystery of God's love. For God's Word, by whom all things were made, was Himself made flesh so that as perfect man He might save all men and sum up all things in Himself. The Lord is the goal of human history, the focal point of the longings of history and of civilization, the center of the human race, the joy of every heart and the answer to all its yearnings. He it is Whom the Father raised from the dead, lifted on high and stationed at His right hand, making Him judge of the living and the dead. Enlivened and united in His Spirit, we journey toward the consummation of human history, one which fully accords with the counsel of God's love: "To reestablish all things in Christ, both those in the heavens and those on the earth" (Eph. 11:10). The Lord Himself speaks: "Behold I come quickly! And my reward is with me, to render to each one according to his works. I am the Alpha and the Omega, the first and the last, the beginning and the end (Rev. 22:12-13).
