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.” 184 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." 185
These dimensions together constitute “one complex reality which comes together from a human and a divine element”: 186
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. 187
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. 188

779 The Church is both visible and spiritual, a hierarchical society and the Mystical Body of Christ. She is one, yet formed of two components, human and divine. That is her mystery, which only faith can accept.
Part 1, Section 2, Chapter 3, Article 9, Paragraph 2, SubSection 2, Heading 2
791 The body’s unity does not do away with the diversity of its members: “In the building up of Christ’s Body there is engaged a diversity of members and functions. There is only one Spirit who, according to his own richness and the needs of the ministries, gives his different gifts for the welfare of the Church.” 222 The unity of the Mystical Body produces and stimulates charity among the faithful: “From this it follows that if one member suffers anything, all the members suffer with him, and if one member is honored, all the members together rejoice.” 223 Finally, the unity of the Mystical Body triumphs over all human divisions: “For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus.” 224

809 The Church is the Temple of the Holy Spirit. The Spirit is the soul, as it were, of the Mystical Body, the source of its life, of its unity in diversity, and of the riches of its gifts and charisms.
