Book excerpt: In Liturgical Catechesis in the 21st Century: A School of Discipleship, Dr. James Pauley explores the sacred action most essential to forming genuine disciples: the transformative encounter with God in the liturgy. Drawing upon important twentieth-century intellectual influences as well as the experience of several of today’s foremost catechetical leaders, this book will inspire readers with a promising new vision for sacramental preparation and mystagogical catechesis, one that places maximum emphasis on apprenticing people into an active and fruitful sacramental life in Christ. Dr. James Pauley stresses the importance of discipleship and apprenticeship, leading from the visible to the invisible realities of the divine encounter with God in the sacraments. The relationship of liturgy and catechesis is vitally important to full, conscious and active liturgical participation, and to the life of holiness and missionary responsiveness which depends upon liturgy as its source. This revised edition has been updated to reflect the 2020 Directory for Catechesis.
