150. What is the mission of the Church?

(Comp 150) The mission of the Church is to proclaim and establish the Kingdom of God begun by Jesus Christ among all peoples. The Church constitutes on earth the seed and beginning of this salvific Kingdom.

“In brief”

(CCC 780) The Church in this world is the sacrament of salvation, the sign and the instrument of the communion of God and men.

To deepen and explain

(CCC 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" (LG 4; Cf. Jn 17:4). Then "the Church was openly displayed to the crowds and the spread of the Gospel among the nations, through preaching, was begun" (AG 4). 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 (Cf. Mt 28:19-20; AG 2; 5-6). (CCC 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" (LG 4). "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" (LG 5).

On reflection

(CCC 769) "The Church… will receive its perfection only in the glory of heaven" (LG 48), 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" (St. Augustine, De civ. Dei, 18, 51: PL 41, 614; cf. LG 8). 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" (LG 5; cf. 6; 2 Cor 5:6). 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" (LG 2).
