CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 770–773

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.

772 It is in the Church that Christ fulfills and reveals his own mystery as the purpose of God's plan: "to unite all things in him." St. Paul calls the nuptial union of Christ and the Church "a great mystery." Because she is united to Christ as to her bridegroom, she becomes a mystery in her turn. Contemplating this mystery in her, Paul exclaims: "Christ in you, the hope of glory."
773 In the Church this communion of men with God, in the "love [that] never ends," is the purpose which governs everything in her that is a sacramental means, tied to this passing world. "[The Church's] structure is totally ordered to the holiness of Christ's members. And holiness is measured according to the 'great mystery' in which the Bride responds with the gift of love to the gift of the Bridegroom." Mary goes before us all in the holiness that is the Church's mystery as "the bride without spot or wrinkle." This is why the "Marian" dimension of the Church precedes the "Petrine."
