The document provides guidance for catechists on preparing children for changes to the Mass resulting from the new Roman Missal translation. It advises catechists to study the changes themselves, choose a positive attitude, and help children understand the changes by explaining what the Missal and translation are, describing the universal Church, and using repetition and songs to help children learn the new responses "by heart". Changes include the Greeting, Penitential Rite, Gloria, and Eucharistic prayers.
