The Eucharist is the source and summit of the Roman Catholic Church, it is the center of life for the parish and the parishioners. Every action of a parish should point to the reality of The Eucharist. This causes the parish to push beyond the understanding of transubstantiation and into an understanding of what the action of the Eucharist means for the daily lives of the parishioners. If parishes were participating in the fullness of what it means to be a Eucharistic Church, there would not be the number of adults leaving as there currently are. This research explores the relationship between The Eucharist and The Church and discusses how individual parishes can better become a Eucharistic parish in the 21<sup>st</sup> century.
