The Instructed Eucharist was developed for use in church, designed to instruct the congregation in the basic actions of the service. Father Marsh recommends that the altar be moved close to the altar rail and that the priest celebrate facing the people so that everyone can see.
The Study Eucharist is designed for class use following the service. It goes into greater depth and explains the meaning and use of the ceremonial which is an integral part of the service in many parishes.
Both parts of this course are bound in a single book.
