A beautifully written and illustrated story that portrays the mystery of the Eucharist in a way that enables children to grasp the teachings of the Holy Sacrifice of the Mass and Holy Communion. Show me the easiest way to teach a lesson, and I'll use it. This book does the job. A plus is that it is written in both English and Spanish. However, my "precious moment" with this book occurred while teaching. . . yes, ADULTS! As a religious education teacher for the Parents whose children are preparing to receive the Holy Eucharist, I took the opportunity to read this book to them before it was read to the children. Their reaction was truly amazing! Even though it is geared for a younger audience, all began voicing their own memories of the first time they received the Holy Eucharist. . .recalling how they felt loved and provided for by Jesus. . .acting like the playful boys in church (distracted), some acting like the caterpillar (getting to mass quite by accident), and some changing and becoming like the butterfly (desiring to be with Christ forever). They all sat there in this moment of peace and grace, as I realized that this story had truly strengthened their own beliefs about the Holy Eucharist!
