No, your the one who needs to calm down. You assume the bread of John 6 is the same bread of the last supper Yet it does not fit.
Jesus never said a person who ate the bread of the last supper would be assured ANY of the things he promised in john 6. In fact, jesus said at the last supper to do it OFTEN, in remembrance of him. So it could not be the "food which endured forever" which one could eat and never die, live forever, never hunger or thirst, and the rest of what he said in John 6.
finally. Jesus prayed and asked God to bless. thats all. Sorry my firend, but according to the the word of god, I can do that, because I am a king and priest until my God.
But non of that matters, It is not the same food.. if it does not give what Jesus promised in john 6, then it is not the same food. period. No matter what ANYONE says.
