Perhaps the doctrine of the Catholic Church most baffling to Protestants and the hardest to accept is her teaching on the Eucharist as both a sacrament and (especially) as the actual Body and Blood of Christ as he offered it on the Cross. But what does the Catholic Church really mean by what she teaches about the Eucharist as opposed to what many have supposed her to mean by it? Does the Catholic teaching have any foundation in the Bible? Did Christ himself say anything about the Eucharist? Is the Eucharist only a symbol; or is it, in the Sacrifice of the Mass, the actual Body and Blood of Christ for our salvation? These questions and others are answered for the Protestant inquirer in this book, which the author hopes will at the very least help the reader to understand that what the Catholic Church believes about the Eucharist is not an invention but is rooted in a profound understanding of the Scriptures.
