Justin Martyr
“We call this food Eucharist, and no one else is permitted to partake of it, except one who believes our teaching to be true and who has been washed in the washing which is for the remission of sins and for regeneration * and is thereby living as Christ enjoined. 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”
(First Apology 66 [A.D. 151]).
Here, we have Justin Martyr writing an Apology (a defense of the Christian faith) to the Roman Emperor Antoninus Pius to try and defend the practices of the Christians and thus end the illegality and persecution of the Church. As such, it had to be very accurate as to the current beliefs of the Catholic Church, as it would be read by high officials, and possibly Antoninus Pius himself. As a classically trained philosopher, he was well-versed in the debating methods of the time, as well as the arguments of the Romans themselves. The First Apology was written in 151 A.D., so the Real Presence is now clearly a Catholic doctrine just a mere 121 years after the death of Christ, and about 50 years after the death of John, the last surviving apostle.
Ignatius of Antioch
“I have no taste for corruptible food nor for the pleasures of this life. I desire the bread of God, which is the flesh of Jesus Christ, who was of the seed of David; and for drink I desire his blood, which is love incorruptible”
(Letter to the Romans 7:3 [A.D. 110]).
“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. They who deny the gift of God are perishing in their disputes”
(Letter to the Smyrnaeans 6:2–7:1 [A.D. 110]).
And finally, we have the most important quote of all. Our existing evidence suggests that Ignatius was trained by none other than the Apostle John
himself, and that he was
personally ordained a bishop by the Apostle Peter. This is a man who intimately knew and conversed with the Apostles, and even HE is professing belief in the Real Presence. He is doing this in his letters to his congregations, and we have written records of it as early as 110 AD. The Didache, written about 70 AD (not by Ignatius, but by an unknown author), is the oldest non-Biblical surviving document that we have about Christianity, and it too emphasizes the sacrificial nature of the Mass.
So what’s the bottom line? If the Real Presence of the Eucharist is a false teaching, then the Apostles themselves incorrectly trained and appointed a bishop with false beliefs, and are responsible for the perversion of the Catholic Church. It is very clear that this would not be likely. There are other documents that also support this opinion, but I’ve only listed the most important and significant ones. I should also point out some relevant Bible passages:
1 Cor. 10:16–17, 11:23–29; and, most forcefully, John 6:32–71
It would also do you well to read “The Lamb’s Supper” by Scott Hahn. It describes in detail how the Catholic Church has always taught that the Book of Revelation by John is in fact an analogy describing the Sacrifice of the Mass. Most of the images used are direct symbolic representations of the various parts of the Catholic Mass. His interpretation is not new (nor is it the only acceptable one), but it does demonstrate how the Mass IS highly Biblical, as is the Real Presence and its sacrificial nature.
I now give you some time to digest all of this…
