Crouan, the author of several studies on liturgical questions including the book The Liturgy Betrayed presents another penetrating work on the state of the Eucharistic Liturgy, the problems and errors that still exist, and how to correct these abuses. The responses Crouan has received to all of his writing and speaking on this topic from Catholics of every stripe show the weariness and confusion of many of the faithful regarding the Sacred Liturgy.

Crouan says that the great majority of Catholics need and want, not celebrations that are "pastorally correct", but a Eucharistic liturgy that offers all the guarantees of Catholicity and leads them to an authentic contemplation of the mysteries being celebrated. He expresses the urgency needed to examine what is going on in parish churches, and to clarify matters by acknowledging the liturgical errors in order to establish a greater fidelity to the real teaching of Vatican II and the Roman Missal.

Denis Crouan, the author of several studies on the pressing liturgical questions of our time, holds a doctorate in Catholic theology. He is also an organist, a choirmaster, a specialist in Gregorian Chant and a professor of literature and history.
