Catechesis is a ministry of teaching and forming that passes on the Word of God to inform the Catholic community and candidates for initiation into the Church about the teachings of Christ, transmitted by the Apostles to the Church.
The word ‘catechesis’ comes from the Greek for “echo” and is intended to nurture the Christian life through imitation in word and deed. The main sources for all catechesis are the Sacred Scriptures and the Catechism of the Catholic Church.
Catechesis is nothing other than the process of transmitting the Gospel, as the Christian community has received it, understands it, celebrates it, lives it and communicates it in many ways.
