The Church is one Because she has as her source and exemplar the unity of the Trinity of Persons in one God. As her Founder and Head, Jesus Christ re-established the unity of all people in one body. As her soul, the Holy Spirit unites all the faithful in communion with Christ. The Church has but one faith, one sacramental life, one apostolic succession, one common hope, and one and the same charity.

charisms

160. What are charisms?
799-801
Charisms are special gifts of the Holy Spirit bestowed on Individuals Which are f or the good of others , the needs of the world, and in particular for the building up of the Church. The discernment of charisms is the Responsibility of the Magisterium     

Holy Spirit

159. Why is the Church called the temple of the Holy Spirit?
797-798
809-810
She is so called because the Holy Spirit resides in the body which is the Church, in her Head and in her members. He also builds up the Church in charity by the Word of God, the sacraments, the virtues, and charisms.

“What the soul is to the human body, the Holy Spirit is to the members of Christ, that is, the body of Christ, which is the Church.” (Saint Augustine)

Bride

158. Why is the Church called the “Bride of Christ”?
796
808
She is called the “Bride of Christ” because the Lord himself called himself her “Spouse” (Mark2:19). The Lord has loved the Church and has joined her to himself in an everlasting covenant. He has given himself up for her in order to purify her with his blood and “sanctify her” (Ephesians5:26), making her the fruitful mother of all the children of God. While the term “body” expresses the unity of the “head” with the members, the term “bride” emphasizes the distinction of the two in their personal relationship.

mystical person

157. Who is the Head of this body?
792-795
807
Christ “is the Head of the body, the Church” (Colossians 1:18). The Church lives from him, in him and for him. Christ and the Church make up the “whole Christ” (Saint Augustine); “Head and members form, as it were, one and the same mystical person” (Saint Thomas Aquinas).

body

156. In what way is the Church the body of Christ?
787-791
805-806
The risen Christ unites his faithful people to himself in an intimate way by means of the Holy Spirit. In this way, those who believe in Christ, in as much as they are close to him especially in the Eucharist, are united among themselves in charity. They form one body, the Church, whose unity is experienced in the diversity of its members and its functions.

Priest, Prophet and King

155. In what way does the people of God share in the three functions of Christ as Priest, Prophet and King?
783-786
The people of God participate in Christ's priestly office insofar as the baptized are consecrated by the Holy Spirit to offer spiritual sacrifices. They share in Christ’s prophetic office when with a supernatural sense of faith they adhere unfailingly to that faith and deepen their understanding and witness to it. The people of God share in his kingly office by means of service, imitating Jesus Christ who as King of the universe made himself the servant of all, especially the poor and the suffering.
