At present, the practice of catechesis, particularly among adults, has been almost completely lost. The classic catechisms take a learner through the Apostles' Creed, the Ten Commandments, and the Lord's Prayer—a perfect balance of biblical theology, practical ethics, and spiritual experience. Also, the catechetical discipline of memorization drives concepts deeper into the heart and naturally enables a learner to be more accountable to master the material than do typical discipleship courses. Finally, the practice of question-answer recitation brings instructors and students into a naturally interactive, dialogical process of learning. Thus, chatechisis is communal and relational.
