At the heart of catechesis: Christ
"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."
