Furthermore, it is a fundamental law in Greek grammar, without exception, that the Article, Pronoun, and Adjective must agree in gender with the Noun to which they refer.
At the Last Supper when our Lord spoke the words of Institution, he was speaking in Aramaic, not Greek. Amongst the 22 churches that make up the Catholic Church, several (including mine) retain those words in the language of Jesus.
This is My body is the Figure Metaphor; and the Figure lies in the Verb IS, which, as in this case always means represents, and must always be so expressed. It can never mean is changed into. Hence in the Figure Metaphor, the Verb represents can always be substituted for is.
The faith of the Catholic Church is based on both a fundamental principle of hermeneutics and the constant faith of the Church from Apostolic times. The Catholic Church teaches that the first principle of hermeneutics--the science of the translation and interpretation of the Bible--is the literal meaning of the text.
The first writer of the New Testament was the apostle Paul. His Letter to the Corinthians was written as early as 56 AD, earlier than the first Gospel, Mark's, written about 64 AD. Paul was also not an eyewitness to what he wrote but testifies to his source.
The next New Testament text in chronological order would have been Mark's Gospel. Written about 64 AD, in Rome, Mark, not an eyewitness, probably heard the account of the Last Supper he recorded from the Apostle Peter.
The third account of the Last Supper could be Matthew's. Matthew, the tax collector Levi, was an eyewitness to the meal. He was one of the twelve Apostles. Matthew probably wrote his Gospel in the 70's.
Luke's account of the Last Supper, written from the standpoint of a Gentile convert and a non-eyewitness, probably heard the details of the Last Supper from Paul. Luke was a traveling companion of Paul. Luke also wrote in the 70's.
The beloved disciple, John, the last of the New Testament writers, wrote his Gospel in the 90's. John was an eyewitness to the events of the Last Supper (Jn 6:30-68).
Hence Catholic Christian belief in the real presence of Jesus Christ in the Eucharist rests upon the literal meaning of the words of the Last Supper as recorded by the Evangelists and Paul.
The uniformity of expression across the first four authors affirms the literalness. Belief in the real presence demands faith--the basis of new life as called for by Christ throughout scripture. But faith in signs conferring what they signify is the basis also for the Incarnation--appearances belying true meaning. The true significance of the real presence is sealed in John's gospel. Five times in different expressions, Jesus confirmed the reality of what he means.
The best way a person can make a clear literal point is repetition of the same message in different ways. Jesus did this. Those around him clearly understood what he was saying--cannibalism and the drinking of blood--both forbidden by Mosaic Law.
Had these disciples mistaken the meaning of Jesus' words, Jesus would surely have known and corrected them. He didn't. They had clearly understood his meaning--Jesus' flesh was to be really eaten; his blood to be really drunk.
Non believers often respond that even at the Last Supper, the apostles did not sense that they had flesh in their hands and blood in their cup. But Jesus is God. The creative literalness of the words: "This is my body; this is my blood" must be believed. God cannot lie. And God can turn bread into flesh and wine into blood without the appearances of bread and wine changing.
Medieval philosophers and theologians called this expression of Divine Truth and Creative Power "transubstantiation". Yes, God can change the substance of any created matter while the appearances remain unchanged. And this demands faith.
Paul confirms elsewhere in his letters the reality of the real presence.
The persuasion of the Church from Apostolic times about the objective reality of these words of Christ is clear from many documents.
Irenaeus (Asia Minor, 140 - 202), Tertullian (Rome, 160 - 220), Cyprian (Carthage, 200 - 258) are just a few of the earliest who attest to the objective reality of the words of Christ.
In the Church in Alexandria, Athanasius (293 - 373) and Cyril (376 - 444) equally attest to the literal meaning of the words of Christ at the Last Supper.
In the Church in Palestine, Cyril (Jerusalem, 315 - 387) and Epiphanius (Salamis, 367 - 403) also affirm in their teaching the same reality.
Unanimity is found across the universal church until the 11th century. Berengar (Tours, France, 1000 - 1088) was one of the first to deny the real presence by arguing that Christ is not physically present, but only symbolically. cf
I am accomplishing my purpose. I am getting the voices out, so that non-Catholics can read what is understood of them by Catholics.
It doesn’t shake me, because I know that there have always been Christians who intimate with the Lord Jesus Christ and filled with the Holy Spirit, and yes, know it, since the time of the Apsotles who were never Catholic (by the Vatican’s definition), nor Protestant (by the Geneva definition). The idea that one must be one or the other if one is a Christian is a falacy and a fantasy.
