This wonderful book proposes a theological model for understanding Eucharistic celebration that demonstrates its centrality to the Christian believer's sanctification and spiritual formation. It centres on John Calvin's framework for understanding the Lord's Supper which was founded upon the believer's union with Christ, along with the belief that the Lord's Supper deepened that union. By bringing Calvin's Eucharistic theology into conversation with contemporary speech-act philosophy, Kevin Vanhoozer's divine/communicative ontology, Biblical theology, and historical and liturgical theology, this multidisciplinary dissertation provides a biblical and theological foundation for understanding the role the Eucharist plays in the worship, sanctification, and formation of the church and her communicants.
