Jesus Christ: mediator and fullness of Revelation

40. God revealed himself progressively to man, through the prophets and through salvific events, until he brought to completion his self-revelation by sending his own Son: (⁸⁶)

"[Jesus Christ] completed and perfected Revelation, he did this by way of his presence and self manifestation—by words and works, signs and miracles, but above all by his death and glorious resurrection from the dead, and finally by sending the Spirit of truth".(⁸⁷)

Jesus Christ is not merely the greatest of the prophets but is the eternal Son of God, made man. He is, therefore, the final event towards which all the events of salvation history converge.(⁸⁸) He is indeed "the Father's one, perfect and unsurpassable Word".(⁸⁹)

41. The ministry of the word must always give prominence to this wonderful characteristic, proper to the economy of Revelation: the Son of God enters human history, assumes human life and death, and brings about the new and definitive covenant between God and man. It is the task of catechesis to show who Jesus Christ is, his life and ministry, and to present the Christian faith as the following of his person.(⁹⁰) Consequently, it must base itself constantly on the Gospels, which "are the heart of all the Scriptures 'because they are our principal source for the life and teaching of the Incarnate Word, our Saviour'".(⁹¹)

The fact that Jesus Christ is the fullness of Revelation is the foundation for the "Christocentricity" (⁹²) of catechesis: the mystery of Christ, in the revealed message, is not another element alongside others, it is rather the centre from which all other elements are structured and illuminated.
