To do what you are saying here requires you to interpret the words of Christ. In the context of John 6 where these words appear, what does Jesus mean if the last supper was totally unknown to those in whom He spoke to? He gives no hint that He will make this clearer to them at that time.
Unknown? It’s pretty clear after hearing this 70 disciples left Jesus because of this hard belief. Jesus told them 4 times that they must eat His flesh and drink his blood. It doesn’t get any simple than that. 1 Corinthians 11:27 also affirms this as well as the writings of the Early Church Fathers. It is pretty clear that we must eat His Flesh. We do so when we break bread.
It is not unknown. In Acts, the Apostles gather in the first day of the week in the breaking of the bread. They under fully that they are eating Jesus.
I do take His word truthfully as you do. Its still comes down to what He meant. If this doctrine was as the catholic church teaches it is, then why don’t we see any of the apostles teaching on it except Paul who mentions the Lords supper but does not say how to change the bread and wine into Christ?
The Catholic Church taught this for over 2,000 years. Scripture in his full context revealed to them that Jesus is the Paschal Lamb. Do you know the significance why John the Baptist called Jesus the Lamb of God, who takes away the sins of the world?
Well, based on Scripture and our Tradition, the Paschal Lamb at Passover is eaten. Jesus is the Lamb that we must eat. He is a pure sacrifice offered to God, the Father. The Apostles are Jews, they understand fully why John, the Baptist called Jesus the Lamb of God.
The Church is called the Bread of Lamb. This is an echoing of Paschal Mystery of the Sacrifice of Christ, especially the Eucharistic Sacrifice.
Like I said, the belief that the bread and wine as symbolic meaning is FOREIGN. This was never the Orthodox Christian belief. Symbolism of the Eucharist is a modern Protestant belief. It is NOT ancient Christianity. Protestant theologians have gone at length to change the deposit of faith. Under whose authority do they have to change that the Eucharist is not Jesus?
You want authentic Christianity. Return to ancient form of Christianity, go back to the Catholic Church. Don’t fall into the modern Protestant theological errors…
