This concept and practice book takes a new approach to First Communion preparation: The celebration of the liturgy itself serves as the introductory path to faith. The First Communion preparation is part of a comprehensive introduction to Christianity, aimed at children and parents of all ages. In six liturgical catecheses, the celebration of the Eucharist is interpreted mystagogically. Additionally, there is a weekend focused on the theme of reconciliation. The book offers exemplary schedules, a variety of materials for liturgical catecheses, and interesting suggestions to integrate faith initiation with all institutions and groups within the parish community. Thus, this book serves as a genuine supplement to the existing First Communion preparation.
