You consume a wafer, nothing more, nothing less.
To use another poster's term above, that is "dead end" theology.
"...Well, toward morning the conversation turned on the Eucharist, which I, being the Catholic, was obviously supposed to defend. Mrs. Broadwater said when she was a child and received the Host, she thought of it as the Holy Ghost, He being the "most portable" person of the Trinity; now she thought of it as a symbol and implied that it was a pretty good one. I then said, in a very shaky voice, "Well, if it's a symbol, to hell with it." That was all the defense I was capable of but I realize now that this is all I will ever be able to say about it, outside of a story, except that it is the center of existence for me; all the rest is expendable." -Flannery O'Connor
Do you understand transubstantiation?
trans = transfer
substantiation = substance.
The substance of bread and wine is changed into the Body and Blood of Christ as Jesus did at the Last Supper when he said, “This is my Body.” “This is my Blood.”
