V. The Spirit And The Church In The Last Days

Pentecost

731 On the day of Pentecost when the seven weeks of Easter had come to an end, Christ’s Passover is fulfilled in the outpouring of the Holy Spirit, manifested, given, and communicated as a divine person: of his fullness, Christ, the Lord, pours out the Spirit in abundance.

732 On that day, the Holy Trinity is fully revealed. Since that day, the Kingdom announced by Christ has been open to those who believe in him: in the humility of the flesh and in faith, they already share in the communion of the Holy Trinity. By his coming, which never ceases, the Holy Spirit causes the world to enter into the “last days,” the time of the Church, the Kingdom already inherited though not yet consummated.

We have seen the true Light, we have received the heavenly Spirit, we have found the true faith: we adore the indivisible Trinity, who has saved us.

The Holy Spirit and the Church

737 The mission of Christ and the Holy Spirit is brought to completion in the Church, which is the Body of Christ and the Temple of the Holy Spirit. This joint mission henceforth brings Christ’s faithful to share in his communion with the Father in the Holy Spirit. The Spirit prepares men and goes out to them with his grace, in order to draw them to Christ. The Spirit manifests the risen Lord to them, recalls his word to them and opens their minds to the understanding of his Death and Resurrection. He makes present the mystery of Christ, supremely in the Eucharist, in order to reconcile them, to bring them into communion with God, that they may “bear much fruit.”

738 Thus the Church’s mission is not an addition to that of Christ and the Holy Spirit, but is its sacrament: in her whole being and in all her members, the Church is sent to announce, bear witness, make present, and spread the mystery of the communion of the Holy Trinity.

In Brief

742 “Because you are sons, God has sent the Spirit of his Son into our hearts, crying, ‘Abba! Father!”‘ (Gal 4:6).

743 From the beginning to the end of time, whenever God sends his Son, he always sends his Spirit: their mission is conjoined and inseparable.

744 In the fullness of time the Holy Spirit completes in Mary all the preparations for Christ’s coming among the People of God. By the action of the Holy Spirit in her, the Father gives the world Emmanuel “God-with-us” (Mt 1:23).

745 The Son of God was consecrated as Christ (Messiah) by the anointing of the Holy Spirit at his Incarnation (cf. Ps 2:6-7).

746 By his Death and his Resurrection, Jesus is constituted in glory as Lord and Christ (cf. Acts 2:36). From his fullness, he poured out the Holy Spirit on the apostles and the Church.

747 The Holy Spirit, whom Christ the head pours out on his members, builds, animates, and sanctifies the Church. She is the sacrament of the Holy Trinity’s communion with men.
