Catechism of the Catholic Church
758 We begin our investigation of the Church's mystery by meditating on her origin in the Holy Trinity's plan and her progressive realization in history.
759 "The eternal Father, in accordance with the utterly gratuitous and mysterious design of his wisdom and goodness, created the whole universe and chose to raise up men to share in his own divine life," 150 to which he calls all men in his Son. "The Father . . . determined to call together in a holy Church those who should believe in Christ." 151 This "family of God" is gradually formed and takes shape during the stages of human history, in keeping with the Father's plan. In fact, "already present in figure at the beginning of the world, this Church was prepared in marvellous fashion in the history of the people of Israel and the old Advance. Established in this last age of the world and made manifest in the outpouring of the Spirit, it will be brought to glorious completion at the end of time." 152
760 Christians of the first centuries said, "The world was created for the sake of the Church." 153 God created the world for the sake of communion with his divine life, a communion brought about by the "convocation" of men in Christ, and this "convocation" is the Church. The Church is the goal of all things, 154 and God permitted such painful upheavals as the angels' fall and man's sin only as occasions and means for displaying all the power of his arm and the whole measure of the love he wanted to give the world:
Just as God's will is creation and is called "the world," so his intention is the salvation of men, and it is called "the Church." 155
761 The gathering together of the People of God began at the moment when sin destroyed the communion of men with God, and that of men among themselves. The gathering together of the Church is, as it were, God's reaction to the chaos provoked by sin. This reunification is achieved secretly in the heart of all peoples: "In every nation anyone who fears him and does what is right is acceptable" to God. 156
762 The remote preparation for this gathering together of the People of God begins when he calls Abraham and promises that he will become the father of a great people. 157 Its immediate preparation begins with Israel's election as the People of God. By this election, Israel is to be the sign of the future gathering of All nations. 158 But the prophets accuse Israel of breaking the covenant and behaving like a prostitute. They announce a new and eternal covenant. "Christ instituted this New Covenant." 159
763 It was the Son's task to accomplish the Father's plan of salvation in the fullness of time. Its accomplishment was the reason for his being sent. 160 "The Lord Jesus inaugurated his Church by preaching the Good News, that is, the coming of the Reign of God, promised over the ages in the scriptures." 161 To fulfill the Father's will, Christ ushered in the Kingdom of heaven on earth. The Church "is the Reign of Christ already present in mystery." 162
764 "This Kingdom shines out before men in the word, in the works and in the presence of Christ." 163 To welcome Jesus' word is to welcome "the Kingdom itself." 164 The seed and beginning of the Kingdom are the "little flock" of those whom Jesus came to gather around him, the flock whose shepherd he is. 165 They form Jesus' true family. 166 To those whom he thus gathered around him, he taught a new "way of acting" and a prayer of their own. 167
765 The Lord Jesus endowed his community with a structure that will remain until the Kingdom is fully achieved. Before all else there is the choice of the Twelve with Peter as their head. 168 Representing the twelve tribes of Israel, they are the foundation stones of the new Jerusalem. 169 The Twelve and the other disciples share in Christ's mission and his power, but also in his lot. 170 By all his actions, Christ prepares and builds his Church.
766 The Church is born primarily of Christ's total self-giving for our salvation, anticipated in the institution of the Eucharist and fulfilled on the cross. "The origin and growth of the Church are symbolized by the blood and water which flowed from the open side of the crucified Jesus." 171 "For it was from the side of Christ as he slept the sleep of death upon the cross that there came forth the 'wondrous sacrament of the whole Church.'" 172 As Eve was formed from the sleeping Adam's side, so the Church was born from the pierced heart of Christ hanging dead on the cross. 173
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." 174 Then "the Church was openly displayed to the crowds and the spread of the Gospel among the nations, through preaching, was begun." 175 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. 176
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." 177 "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." 178
769 "The Church . . . will receive its perfection only in the glory of heaven," 179 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." 180 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." 181 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." 182
