In his latest book, The Lord's Supper: What It Is and What It's Not, David Rodriguez examines some of the claims for the Eucharist celebration, such as Administering grace, Providing eternal life, Imparting forgiveness of sins, Furnishing the presence of Christ, Repeating the sacrifice of Christ. We also explore the different traditions regarding the sacraments and, more importantly, the basis upon which these traditions are established. The author addresses these issues from the perspective that the Scriptures are the only infallible guide to Christian doctrine and that the primary source of church doctrine must be the teachings of Christ and His apostles. The reader should be prepared to have some of his or her deeply held religious teachings challenged by the word of God.
