Jesus said he was the bread that came down from heaven. (John 6:51) This takes us back to Exodus and the traditions that began at that time. Manna, from God, came down from heaven. This is not the only place in Exodus where bread is mentioned. We also have the Bread of the Presence (face bread) that was baked and placed in the Tabernacle (later the Temple) in the Presence of the Lord. Each week the Bread of the Presence was consumed by the priests because that bread had been surrounded by (absorbed) the Presence of God.
God became man. He said he was the bread that came down from heaven. He taught us that his body was true food; his blood true drink. Those who believed and ate/gnawed his body and drank his blood would have his life within them.
Humans are made up of body, mind, and soul/spirit. Until Christ, God was only Spirit and His spirit in both manna and in the Bread of the Presence came down from heaven and was consumed by men. With Jesus, God now had both Body and Spirit. This is the new bread that came down from heaven and is God still feeding his people--body, blood, and divinity.
And thus to this day we consume bread (body, blood, and divinity) from heaven. Early Christians understood this, and as mentioned before, were accused of cannibalism. Their belief in God's bread from heaven that strong. This is my body...this is my blood. God in the midst of His people.
Jesus explained his presence in bread and wine to the people of his own time. Some said, We cannot accept this. They no longer followed him. Jesus did not try to call them back, did not send his Apostles to go running after them to explain he was only speaking metaphorically. He simply asked his Apostles, Will you go, too? Peter answered, "Lord, to whom shall we go? You have the words of eternal life."
What you seem to be asserting,
hadit , is that while you may believe Jesus had the power to perform miracles--even raising Lazarus from the dead--Jesus did not, and does not, have the power to send his whole presence--body, blood, and divinity--into bread and wine. You want a sign he can do this. You want to taste actual flesh. You want to taste actual blood. (Send me a sign! But no sign would/will be given except the sign of Jonah. You believe Jesus had the power to rise from the dead, but that's his limit?)
On the road to Emmaus, we are told that Jesus pointed to all scriptures that referred to him. And then, when in Emmaus, his disciples recognized him in the breaking of the bread.
The Apostles, being Jews, were well aware of the Bread of the Presence eaten by priests. But Jesus...he was to be eaten by all who believe. You have no belief/faith to offer when it comes to this. However, you do have remembrance, and you are assuring us this remembrance is all that is needed.
You want those who come to Mass in the Catholic Church to just offer remembrance so all can come together. The only way I see this happening is if the Catholic Church has a separate line of bread and wine--that has not been consecrated--for non-believing Christians to receive.
