CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 767–771

767 "When the work which the Father gave the Son to do on earth was accomplished, the Holy Spirit was sent on the day of Pentecost in order that he might continually sanctify the Church." Then "the Church was openly displayed to the crowds and the spread of the Gospel among the nations, through preaching, was begun." As the "convocation" of all men for salvation, the Church in her very nature is missionary, sent by Christ to all the nations to make disciples of them.
768 So that she can fulfill her mission, the Holy Spirit "bestows upon [the Church] varied hierarchic and charismatic gifts, and in this way directs her." "Henceforward the Church, endowed with the gifts of her founder and faithfully observing his precepts of charity, humility and self-denial, receives the mission of proclaiming and establishing among all peoples the Kingdom of Christ and of God, and she is on earth the seed and the beginning of that kingdom."
769 "The Church . . . will receive its perfection only in the glory of heaven," at the time of Christ's glorious return. Until that day, "the Church progresses on her pilgrimage amidst this world's persecutions and God's consolations." Here below she knows that she is in exile far from the Lord, and longs for the full coming of the Kingdom, when she will "be united in glory with her king." The Church, and through her the world, will not be perfected in glory without great trials. Only then will "all the just from the time of Adam, 'from Abel, the just one, to the last of the elect,' . . . be gathered together in the universal Church in the Father's presence."
770 The Church is in history, but at the same time she transcends it. It is only "with the eyes of faith" that one can see her in her visible reality and at the same time in her spiritual reality as bearer of divine life.
771 "The one mediator, Christ, established and ever sustains here on earth his holy Church, the community of faith, hope, and charity, as a visible organization through which he communicates truth and grace to all men." The Church is at the same time:

- a "society structured with hierarchical organs and the mystical body of Christ;

- the visible society and the spiritual community;

- the earthly Church and the Church endowed with heavenly riches."

These dimensions together constitute "one complex reality which comes together from a human and a divine element":

The Church is essentially both human and divine, visible but endowed with invisible realities, zealous in action and dedicated to contemplation, present in the world, but as a pilgrim, so constituted that in her the human is directed toward and subordinated to the divine, the visible to the invisible, action to contemplation, and this present world to that city yet to come, the object of our quest.

O humility! O sublimity! Both tabernacle of cedar and sanctuary of God; earthly dwelling and celestial palace; house of clay and royal hall; body of death and temple of light; and at last both object of scorn to the proud and bride of Christ! She is black but beautiful, O daughters of Jerusalem, for even if the labor and pain of her long exile may have discolored her, yet heaven's beauty has adorned her.
