Reign in Blood. In this episode of Banned Books, we discuss the Lord’s Supper while reading The Last Supper: The Testament of Jesus by Reinhard Schwarz. We discuss why the distinction between a covenant and a testament is of utmost importance for exegesis, sacramental theology, and Christian life, why promise and gift are central to Luther’s understanding of the sacrament, and how rejecting the sacrament leads to a denial of Christ.
