To accept the Eucharist, as understood by Roman Catholicism, you have to deny Hebrews.
As the Bible does not contradict itself only one of these positions can be correct.
Catholic "sacred tradition" is not reliable in that it contradicts itself and the Bible on more than one occasion.
To accept only John 6:53, as roman catholics do, ignores the remainder of John 6 on this issue. As it does the rest of the NT.
To claim the disciples practiced the Eucharist as understood by Roman Catholicism ignores the Bible. We have no record of the disciples believing in the transubstantiation of the bread and wine as espoused by catholicism.
When Peter preached at and after Pentecost, did he say, come and eat the flesh and blood of Christ? NO!
It was repent and believe.
Did Paul say to eat the flesh and blood of Christ? NO!
He preached you come to faith through Christ.
It is really embarrassing, and blasphemous, for the catholic to continue to insist in this false teaching that is contrary to the Word. It is very similar to the Jews who came to the early believers and told them they had to be circumcised to be saved.
And for the last time...the roman catholic church did not give the world the Bible. It was in place long before the edifice known as roman catholicism came into existence.
To agree with you, you will have to ignore the understanding of Christ’s very text in John 6:47-6:55, the understanding his disciples placed on his word that they made this a central act of their worship; the early Church fathers, and the long litany of saints, martyrs, stigmatists, and those who sifted through hundreds and hundred of fragments of papyrus, their discussions on these, the solemn acts of the Church leaders and a galaxy of historical scholars, theologians, and historians. What more, it undercuts the Divine Authority handed to Peter and his successor to teach ONE truth as the basis of ONE Church for ALL peoples until the end of time.
The rest is all kumbaya to each his own.
This is always how eisogesis must work. Context refutes the careful phrases highlighted.
