The purpose of this catechism is to present an organic and synthetic exposition of the essential and fundamental contents of Catholic doctrine both on faith and on morals, in the light of the Second Vatican Council and the whole of the Tradition of the Church. Its main sources are Sacred Scripture, the Holy Fathers, the Liturgy and the Magisterium of the Church. It is intended to serve "as a point of reference for the catechisms or compendia that are composed in the various countries" (Synod of Bishops 1985. Final report II B A 4).
Catechesis is the name given to all the efforts made in the Church to make disciples, to help men to believe that Jesus is the Son of God so that, by faith, they may have life in his name, and to educate them and instruct them in this life and thus build the Body of Christ (Cf. John Paul II, CT 1,2).
The purpose of First Communion is the education in the faith of children, youth and adults, which includes especially a teaching of Christian doctrine.
In a more specific sense, “globally, catechesis can be considered here as an education in the faith of children, young people and adults that includes especially a teaching of Christian doctrine, generally given in an organic and systematic way with a view to to initiate them into the fullness of Christian life ”(CT 18).
