Based on what?
Seriously, I would like to know the basis of your rejection of what the Church has taught from day one.
That's not what Jesus said.
Jesus said:
Jhn 6:48-51 “
I am the bread of life. Your fathers ate the manna in the wilderness, and are dead. This is the bread which comes down from heaven, that one may eat of it and not die. I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.”
and
Jhn 6:53-58 “
Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. For My flesh is food indeed, and My blood is drink indeed. He who eats My flesh and drinks My blood abides in Me, and I in him.
As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me. This is the bread which came down from heaven—not as your fathers ate the manna, and are dead. He who eats this bread will live forever.”
Of course, you are free to accept that passage at face value or as some kind of metaphor.
However, the entire Church, from the beginning, taught that the bread was the body of Christ and the wine was the blood of Christ.
For example:
Ignatius of Antioch (30-107 A. D. A disciple of the apostle John and Bishop of Antioch) in his
Epistle to the Smyrnaens, Ch. VII: “Let Us Stand Aloof from Such Heretics” states; “
They (the heretics) abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Savior Jesus Christ, which suffered for our sins,..”
Ignatius was taught by the John, the beloved disciple of Christ and, in this statement, he affirms the teaching of the apostles and Christ that the bread is Christ’s body.
Justin Martyr, the church’s first apologist, wrote in the first half of the 2nd century in his “The First Apology of Justin”, in Chapter LXVI.—Of the Eucharist. In it he reports what he was taught as a new Christian by the church. That would mean that the teaching he received was already established in the church. It is part of the teaching of the apostles who taught what they learned from Jesus. It is God’s inspired teaching to the church by His Son, through the apostles to the church.
“
And this food is called among us Eujcaristiva [the Eucharist], of which no one is allowed to partake but the man who believes that the things which we teach are true, and who has been washed with the washing that is for the remission of sins, and unto regeneration, and who is so living as Christ has enjoined. For not as common bread and common drink do we receive these; but in like manner as Jesus Christ our Savior, having been made flesh by the Word of God, had both flesh and blood for our salvation, so likewise have we been taught that the food which is blessed by the prayer of His word, and from which our blood and flesh by transmutation are nourished, is the flesh and blood of that Jesus who was made flesh. For the apostles, in the memoirs composed by them, which are called Gospels, have thus delivered unto us what was enjoined upon them; that Jesus took bread, and when He had given thanks, said, “This do ye in remembrance of Me, this is My body; ”and that, after the same manner, having taken the cup and given thanks, He said, “This is My blood; ”and gave it to them alone.”
