The General Directory for Catechesis (#’s 85 & 86) tells us that catechesis is: Promoting knowledge of the faith, which is what we call religious education;

liturgical education, leading a true liturgical life;
moral formation, learning the Way based on conversion to Jesus Christ;
teaching to pray, which requires apprenticeship;
education for community life, including the ecumenical dimension
development of households of faith;
preparation to work in the vineyard as an active minister in an interfaith setting.
