Are you serious about the Eucharist?....you obviously have not read the bible have you? Read John 6.......why does Paul say you must receive the body of blood of Jesus worthily? Why did the early Christians risk and sacrifice their lives to receive the Eucharist if it was a symbol...why did the Romans call then "cannibals" if it were a symbol....why did the early Church, prior to the New Testament believe in the real presence.
Scripture is against you and history is against you.
In John 6, disciples left Jesus because they could not grasp the real presence. The teaching was "hard" and they left him. This was the first time any disciples left Jesus because of his teaching. I could see you as their leader.
