The Revelation of God, culminating in Jesus Christ, is destined for all mankind: "He (God) desires all men to be saved and to come to the knowledge of the truth" (1 Tim 2,4) 93Cf.DV 7. In virtue of his universal salvific will, God has ordained that Revelation should be transmitted to all peoples and to all generations and should remain always in its entirety.
To fulfil this divine plan, Jesus Christ founded the Church, built on the Apostles. He gave them the Holy Spirit from the Father and sent them to preach the Gospel to the whole world. The Apostles, by words, deeds and writings, faithfully discharged this task.94Cf. DV 7a. This Apostolic Tradition is perpetuated in the Church by means of the Church herself. The entire Church, pastors and faithful, is responsible for its conservation and transmission. The Gospel is conserved whole and entire in the Church: the disciples of Jesus Christ contemplate it and meditate upon it unceasingly; they live it out in their everyday lives; they proclaim it in their missionary activity. As the Church lives the Gospel she is continually made fruitful by the Holy Spirit. The Spirit causes her to grow constantly in her understanding of the Gospel, prompts her and sustains the task of proclaiming the Gospel in every corner of the world.95Cf. DV 8 and CCC 75-79.
The integral conservation of Revelation, the word of God contained in Tradition and Scripture, as well as its continuous transmission, are guaranteed in their authenticity. The Magisterium of the Church, sustained by the Holy Spirit and endowed with "the sure charism of truth",96DV 10b; cf CCC 85-87. exercises the function of "authentically interpreting the word of God".97LG 448; AG 1; GS 45; cf. CCC 774-776.
The Church, "universal sacrament of salvation", born of the Holy Spirit, transmits Revelation through evangelization; she announces the Good News of the salvific plan of the Father and in the sacraments, communicates his Diving gifts. To God who reveals himself is due this obedience of faith by which man adhers to the "Gospel of the grace of God". (Acts 20,24) with full assent of the intellect and of the will. Guided by faith, by means of the gift of the Spirit, man succeeds in attaining to contemplate and to delight in the God of love, who in Christ has revealed the riches of his glory.98Cf. Col 1,26.
