The Roman Canon, also known as the First Eucharistic Prayer, holds a privileged place among the texts used in the Mass. With the release of a new English translation of the Latin Roman Missal, Father Milton Walsh’s timely meditation on the Roman Canon can help priests, religious, and laity deepen their understanding of the text that for centuries was the only Eucharistic prayer used in the Roman Rite. Drawing on the biblical and liturgical scholarship of the twentieth century, Father Walsh provides spiritual reflections on each of the prayers that make up the Roman Canon. This ancient prayer took shape during the golden age of the Fathers of the Church, from the fourth to the sixth centuries, and is rich in biblical allusions and theological meaning.In Memory of Me explores the themes of thanksgiving, offering, and intercession that recur throughout the prayer. It explains the centrality of sacrifice in the Eucharist: not only Christ’s sacrifice on the Cross and the sacrifice of the Mass, but also the offerings of the Old Testament and the self-offering of the martyrs. The trinitarian nature of the Canon, in particular the question of the role of the Holy Spirit, is also treated, as well as the relationship between earthly and heavenly worship.
