In order to express its vitality and to be efficacious, catechesis today needs to undertake the following challenges and directions: – Above all it needs to present itself as a valid service to evangelization of the Church with an accent on missionary character; – It should address itself to those who have been and continue to be its privileged recipients: children, adolescents, young people and adults; – Based on the example of catechesis in the patristic era, it needs to form the personality of the believer and therefore be a true and proper school of Christian pedagogy; – It needs to announce the essential mysteries of Christianity, promoting the trinitarian experience of life in Christ as the center of the life of faith; – It needs to consider as its primary task the preparation and formation of catechists in the deep riches of the faith.
