We don't stop learning when we leave school - we go on acquiring skills and expertise in all kinds of aspects of life: personal, social, personal; we acquire a wealth of experience and great deal of wisdom if we reflect on it. Our life of faith is no different. We can grow in it by taking time to learn, to reflect and to pray. 

Catechesis and Everyone

Catechesis is a responsibility of the entire Christian community. This is should not be the work of catechists and priests alone, but of the whole community of the faithful. The Christian community follows the development of catechetical processes, for children, young people and adults, as a duty that involves and binds it directly. (GDC 220) 

A fully Christian community can exist only when a systematic catechesis of all its members takes place and when an effective and well developed catechesis of adults is regarded as the central task of the catechetical enterprise.” (ACCC, no. 25).
