This book is a historical-theological commentary on the approved, postconciliar, Eucharistic prayers of the Roman Rite. The author, Father Enrico Mazza, traces each prayer to its root time and gives the reader the cultural-theological climate of those times before analyzing the theological principles as translated in the prayers today. Enrico Mazza is professor of liturgical history at the Universite Cattolica del Sacro Cuore in Milan. He is the author of Mystagogy: A Theology of Liturgy in the Patristic Ages and Eucharistic Prayers of the Roman Rite.
