In Level I, the heart of the catechesis revolves around the Parable of the Good Shepherd. Jesus announces that he is the Good Shepherd who calls each one by name. The sheep listen to the voice of the Shepherd and follow him. The children also enter into the mystery of the Eucharist by first learning the names of the articles used on the altar and then through the most important gestures including the preparation of the chalice, the epiclesis and offering, and the sign of peace. Through the experience of seeing these gestures, presented one by one, the Mass emerges as the Sacrament of the Gift. The child becomes acquainted with the historical character of the liturgy through the events of the Last Supper, Christ’s death, and His resurrection.
