This book explores what Catholics and Methodists believe about eucharistic sacrifice. Eucharistic sacrifice refers to the offering that Christ and his church make in the celebration of the Lord's Supper. It is, therefore, both a Christian doctrine and a church practice. The sacrificial dimension of the sacrament comes both from Christ's sacrifice on the cross and from his self-offering at the Last Supper in which Christ gives himself to the Father on behalf of his people. "This is my body, which is given for you" (Luke 22:19). The eucharist is a sacrificial meal because in the bread and cup Christians are united to the body and blood of Christ that was sacrificed for them on the cross. Moreover, the resurrected Lord is really present with his people in the eucharist, and while his historic crucifixion is an event in the past, Jesus' salvation continues and his grace is given to his people in the sacrament, "for this is my blood of the covenant, which is poured out for many for the forgiveness of sins" (Matthew 26:28). Catholics and Methodists believe that Jesus instructs his followers to repeat his words and actions from the Last Supper in their celebration of the eucharist, but a long running assumption is that Catholics and Methodists—following the historic Reformation schism—are deeply divided over eucharistic sacrifice. This book challenges that assumption by analyzing what these churches teach on eucharistic sacrifice from historical, sacramental, liturgical, and ecumenical perspectives. Key figures like Thomas Aquinas and John Wesley help define eucharistic sacrifice in each tradition. Subsequently, authoritative texts such as ecclesial statements, eucharistic prayers, and hymns further specify what Catholics and Methodists believe they are doing when they offer the eucharist to God. Sours argues that far from being divided, Catholics and Methodists have much in common regarding this controversial doctrine.
