“At the heart of catechesis we find, in essence, a Person, the Person of Jesus of Nazareth, the only Son from the Father. . .who suffered and died for us and who now, after rising, is living with us forever.” To catechize is “to reveal in the Person of Christ the whole of God’s eternal design reaching fulfilment in that Person. It is to seek to understand the meaning of Christ’s actions and words and of the signs worked by him.” Catechesis aims at putting “people . . . in communion . . . with Jesus Christ: only he can lead us to the love of the Father in the Spirit and make us share in the life of the Holy Trinity.”
In catechesis “Christ, the Incarnate Word and Son of God,. . . is taught – everything else is taught with reference to him – and it is Christ alone who teaches – anyone else teaches to the extent that he is Christ’s spokesman, enabling Christ to teach with his lips. . . Every catechist should be able to apply to himself the mysterious words of Jesus: ‘My teaching is not mine, but his who sent me.'”
Whoever is called “to teach Christ” must first seek “the surpassing worth of knowing Christ Jesus”; he must suffer “the loss of all things. . .” in order to “gain Christ and be found in him”, and “to know him and the power of his resurrection, and (to) share his sufferings, becoming like him in his death, that if possible (he) may attain the resurrection from the dead”.
From this loving knowledge of Christ springs the desire to proclaim him, to “evangelize”, and to lead others to the “yes” of faith in Jesus Christ. But at the same time the need to know this faith better makes itself felt. To this end, following the order of the Creed, Jesus’ principal titles – “Christ”, “Son of God”, and “Lord” (article 2) – will be presented. the Creed next confesses the chief mysteries of his life – those of his Incarnation (article 3), Paschal mystery (articles 4 and 5) and glorification (articles 6 and 7).
