Well - the Apostles and Early Church Fathers disagree with you:
1 Cor. 23-30* - (Pretty harsh words from Paul if this is simply a “symbol*” . . .)
**For I received from the Lord what I also handed on to you, that the Lord Jesus, on the night he was handed over, took bread, **and, after he had given thanks, broke it and said, "This is my body that is for you. Do this in remembrance of me."
In the same way also the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me."
For as often as you eat this bread and drink the cup, you proclaim the death of the Lord until he comes.
Therefore whoever eats the bread or drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord.
A person should examine himself, and so eat the bread and drink the cup.
For anyone who eats and drinks without discerning the body, eats and drinks judgment on himself.
That is why many among you are ill and infirm, and a considerable number are dying.
Ignatius of Antioch
Take note of those who hold heterodox opinions on the grace of Jesus Christ which has come to us, and see how contrary their opinions are to the mind of God. . . . They abstain from the Eucharist and from prayer because they do not confess that the Eucharist is the flesh of our Savior Jesus Christ, flesh which suffered for our sins and which that Father, in his goodness, raised up again.
Justin Martyr
For not as common bread nor common drink do we receive these, but since Jesus Christ our Savior was made incarnate by the word of God and had both flesh and blood for our salvation, so too, as we have been taught, the food which has been made into the Eucharist by the Eucharistic prayer set down by him, and by the change of which our blood and flesh is nurtured, is both the flesh and the blood of that incarnated Jesus.
Aphraahat
After having spoken thus [at the Last Supper], the Lord rose up from the place where he had made the Passover and had given his body as food and his blood as drink, and he went with his disciples to the place where he was to be arrested. But he ate of his own body and drank of his own blood, while he was pondering on the dead. With His own hands the Lord presented his own body to be eaten, and before he was crucified he gave his blood as drink (Treatises 12:6 [A.D. 340]).
Augustine
That bread which you see on the altar having been sanctified by the word of God is the body of Christ. That chalice, or rather, what is in that chalice, having been sanctified by the word of God, is the blood of Christ(Sermons 227 [A.D. 411]).
What you see is the bread and the chalice, that is what your own eyes report to you. But what your faith obliges you to accept is that the bread is the body of Christ and the chalice is the blood of Christ. This has been said very briefly, which may perhaps be sufficient for faith, yet faith does not desire instruction (ibid. 272).
According to the Apostles and Early Fathers - you simply have no faith, friend.
