That is a simplication. I am Presbyterian. We believe in the spiritual presence of Jesus, not the physical.
It is not merely a symbol. That is Baptist thinking.
However, we can scream all day about "this is my body" and "eat my flesh and drink my blood" and it will get us nowhere.
I will point out "do this in remembrance of me"...hardly a statement indicating a literal feast of Christ's skin, bone, joints etc. this is my body etc. are simply metaphors. It is like when you use something to stand for something else, you will tend to simply say "blank is blank," not "blank is the complete and full representation of blank," but that is what you mean.
I just don't have a CLUE how it cold be ANY CLEARER of what Jesus SAID!!
All...ALL Protestant religions came AFTER the Catholic religion because the RULES to follow are too hard for some. I have a list of the names of men and the dates that all other Christian religions were started. I'm not begrudging you your religion, I';m just stating facts.
