I think someone who learned the faith from the Apostle John would know if the Eucharist is the Body of Christ as Jesus declared and Christians have always believed or is it symbolic as was first taught in the 16th century.
please read post #23 to see what that man taught by John had to say on the subject.
he wrote this before he was put to death in Rome for his faith.
Then, having taken the bread and given it to His disciples, He made it His own body, by saying, "This is my body," that is, the figure of my body. A figure, however, there could not have been, unless there were first a veritable body (Against Marcion, Bk 4).Ignatius is saying the same thing. It is a quite typical mode of expression under the platonic mode of relating type to archetype. There is a relationship, and it can be expressed very directly, "A is B," and still have the sense of what we moderns would think of as a symbolic reference.
