The Cross was present at the Eucharist in early Christianity as an idea, a gesture, and an object. Over time, these different actualizations of the quintessential symbol of Christianity have generated important questions about their meaning and function, among them: is the Eucharist a meal and/or a sacrifice? Can the sign of the Cross illuminate the absence of a Roman epiclesis? Is it pertinent -historically and theologically - to use an altar Cross? In this study, Daniel Cardó explores the relation between the Cross and the Eucharist. Offering a thorough and fresh reading of patristic and Roman liturgical texts, he identifies their emphases and common themes on the Cross and the Eucharist, and demonstrates their significance for the liturgical debates of recent decades.
