This work is intended primarily for those responsible for catechesis: first of all the bishops, as teachers of the faith and pastors of the Church. It is offered to them as an instrument in fulfilling their responsibility of teaching the People of God. Through the bishops, it is addressed to redactors of catechisms, to priests, and to catechists. It will also be useful reading for all other Christian faithful.
