Adult catechesis seeks to present the church in all its dimensions, including its missionary nature, its role as sign or sacrament of Christ’s presence in the world, its ecumenical commitment, and its mandate to communicate the whole truth of Christ to all persons in all times. (Matthew 28,30)

Adult catechesis includes the study of scripture, tradition, liturgy, theology, morality, and the church’s teaching authority of life. Church history is important for placing events in proper perspective. Because Christ commissioned the apostles to teach people to observe everything He had commanded, catechesis includes “not only those things which are to be believed, but also those things which are to be done.” (General Catechetical Directory, 63)
