In this book, the current Pope expounds upon the nature of and the importance of the Eucharist ,which he believes is the heart of Christian life. He sees it as a mysterious phenomenon whereby Jesus is transformed into bread and wine , which ,once consumed by the communicant, unites that person with Christ. I bought the book seeking more enlightenment about this ritual having participated in the Eucharist myself for several months. Something mysterious and profound does indeed take place during Communion ; I get a feeling of peace , cleansing and oneness and the sense that something supernatural has taken place. It is the main reason why I bother going to church. This book provided me with a little more information about the phenomenon, although there is a lot of waffle in it to be honest. I guess what happens in the Eucharist is a bit of a mystery really ; does Jesus really transform himself into bread and wine , or is there some other supernatural force at work here ? I would like to believe that it is the former , but having just read the Old Testament from cover to cover and having found precious little in it prophesying the coming of Christ , I'm beginning to have some doubts.
