Athanasius Anti-transubstantiation
On John 6:
“I saw an example of this in the Gospel of John, where treating concerning the eating of his body, and seeing many offended there by, he said, “Does this offend you, what if ye shall see the Son of man ascend where he was before? It is the spirit that quickeneth, the flesh profiteth nothing. The words which I speak unto you, they are spirit and life.” He spake both of the spirit and the flesh, and made a distinction between his spirit and flesh, that not only believing in what was visible to their eyes, but also in his invisible nature, they might learn that the things which he said were not carnal, but spiritual : for, for haw many would his body have sufficed for meat that it should become the nourishment of the whole world? For this reason, therefore, he mentions the Son of man’s ascension into heaven that he might draw them from the corporeal sense, and that they might understand, that the flesh he spoke of was heavenly nourishment and spiritual food given to them from above. For the words which I speak unto you, they are spirit and life. As if he had said, This my body which is shown to you and is given for the world, shall be given as food, so as to be imparted spiritually within each, and to become to each a safe guard against the resurrection of eternal life.” (Festal Letter, 4.19)
Clement of Alexandria — Anti-Transubstantiation
Clement on John 6 – Eating of flesh and blood figures for faith.
“And entertaining this view, we may regard the proclamation of the Gospel, which is universally diffused, as milk; and as meat, faith, which from instruction is compacted into a foundation, which, being more substantial than hearing, is likened to meat, and assimilates to the soul itself nourishment of this kind. Elsewhere the Lord, in the Gospel according to John, brought this out by symbols, when He said: Eat my flesh, and drink my blood; John 6:34 describing distinctly by metaphor the drinkable properties of faith and the promise, by means of which the Church, like a human being consisting of many members, is refreshed and grows, is welded together and compacted of both—of faith, which is the body, and of hope, which is the soul; as also the Lord of flesh and blood. For in reality the blood of faith is hope, in which faith is held as by a vital principle.” (Clement of Alexandria, The Paedagogus, Book I)
(See Augustine on John 6, “Why dost thou ready teeth and stomach? Believe, and thou hast eaten already.”)
The Word figuratively described by a multitude of elements, including wine.
“Thus in many ways the Word is figuratively described, as meat, and flesh, and food, and bread, and blood, and milk. The Lord is all these, to give enjoyment to us who have believed on Him. Let no one then think it strange, when we say that the Lord’s blood is figuratively represented as milk. For is it not figuratively represented as wine? Who washes, it is said, His garment in wine, His robe in the blood of the grape. Genesis 49:11 In His own Spirit He says He will deck the body of the Word; as certainly by His own Spirit He will nourish those who hunger for the Word.” (Clement of Alexandria, The Paedagogus, Book I)
Wine the symbol of the sacred blood
“The Scripture, accordingly, has named wine the symbol of the sacred blood; but reproving the base tippling with the dregs of wine, it says: Intemperate is wine, and insolent is drunkenness. Proverbs 20:1” (Clement of Alexandria, The Paedagogus, Book II)
Justin Martyr – Anti-transubstantiation
The Eucharist is bread and wine given in remembrance of Christ.
“The people who are become depreciated, and there is no understanding in him who hears.’ Now it is evident, that in this prophecy[allusion is made] to the bread which our Christ gave us to eat, in remembrance of His being made flesh for the sake of His believers, for whom also He suffered; and to the cup which He gave us to drink, in remembrance of His own blood, with giving of thanks. And this prophecy proves that we shall behold this very King with glory; and the very terms of the prophecy declare loudly, that the people foreknown to believe in Him were fore-known to pursue diligently the fear of the Lord. Moreover, these Scriptures are equally explicit in saying, that those who are reputed to know the writings of the Scriptures, and who hear the prophecies, have no understanding. And when I hear, Trypho,” said I, “that Perseus was begotten of a virgin, I understand that the deceiving serpent counterfeited also this.” (Justin Martyr, Dialogue with Trypo, CHAPTER LXX)
Irenaeus – Anti-Transubstantiation
Consubstantiation (Two realities at once, rather than one reality of Christ in the wine and bread).
”But our opinion is in accordance with the Eucharist, and the Eucharist in turn establishes our opinion. For we offer to Him His own, announcing consistently the fellowship and union of the flesh and Spirit. For as the bread, which is produced from the earth, when it receives the invocation of God, is no longer common bread, but the Eucharist, consisting of two realities, earthly and heavenly; so also our bodies, when they receive the Eucharist, are no longer corruptible, having the hope of the resurrection to eternity.” (Irenaeus, Against Heresies, Book IV, Chapter 18)
The Cup of the Covenant drank with the Apostles not the blood of Christ, but, instead, is the fruit of the vine.
“Thus, then, He will Himself renew the inheritance of the earth, and will re-organize the mystery of the glory of [His] sons; as David says, He who has renewed the face of the earth. He [Christ] promised to drink of the fruit of the vine with His disciples [Matt 26:29], thus indicating both these points: the inheritance of the earth in which the new fruit of the vine is drunk, and the resurrection of His disciples in the flesh. For the new flesh which rises again is the same which also received the new cup. And He cannot by any means be understood as drinking of the fruit of the vine when settled down with his [disciples] above in a super-celestial place; nor, again, are they who drink it devoid of flesh, for to drink of that which flows from the vine pertains to flesh, and not spirit.” (Irenaeus, Against Heresies, 5:33:1)
Against the misunderstanding that the bread and wine is actually flesh and blood:
“For when the Greeks, having arrested the slaves of Christian catechumens, then used force against them, in order to learn from them some secret thing [practiced] among Christians, these slaves, having nothing to say that would meet the wishes of their tormentors, except that they had heard from their masters that the divine communion was the body and blood of Christ, and imagining that it was actually flesh and blood, gave their inquisitors answer to that effect. Then these latter, assuming such to be the case with regard to the practices of Christians, gave information regarding it to other Greeks, and sought to compel the martyrs Sanctus and Blandina to confess, under the influence of torture, [that the allegation was correct]. To these men Blandina replied very admirably in these words: ‘How should those persons endure such [accusations], who, for the sake of the practice [of piety], did not avail themselves even of the flesh that was permitted [them to eat]?’” (Fragment 13)
Tertullian – Anti-Transubstantiation
On John 6, Flesh and Blood of Christ digested through faith. No literal enjoinment to eat Christ’s flesh.
“He says, it is true, that the flesh profits nothing; John 6:63 but then, as in the former case, the meaning must be regulated by the subject which is spoken of. Now, because they thought His discourse was harsh and intolerable, supposing that He had really and literally enjoined on them to eat his flesh, He, with the view of ordering the state of salvation as a spiritual thing, set out with the principle, It is the spirit that quickens; and then added, The flesh profits nothing,— meaning, of course, to the giving of life. He also goes on to explain what He would have us to understand by spirit: The words that I speak unto you, they are spirit, and they are life. In a like sense He had previously said: He that hears my words, and believes in Him that sent me, has everlasting life, and shall not come into condemnation, but shall pass from death unto life. John 5:24 Constituting, therefore, His word as the life-giving principle, because that word is spirit and life, He likewise called His flesh by the same appellation; because, too, the Word had become flesh, John 1:14 we ought therefore to desire Him in order that we may have life, and to devour Him with the ear, and to ruminate on Him with the understanding, and to digest Him by faith. Now, just before (the passage in hand), He had declared His flesh to be the bread which comes down from heaven, John 6:51 impressing on (His hearers) constantly under the figure of necessary food the memory of their forefathers, who had preferred the bread and flesh of Egypt to their divine calling. Then, turning His subject to their reflections, because He perceived that they were going to be scattered from Him, He says: ‘The flesh profits nothing.’” (Tertullian, On the Resurrection of the Flesh, Chpt. 37)
The bread and wine the figure of Christ’s body, against those who deny that Christ did not have a body.
“Having taken bread and having distributed it to His disciples, He made it His own Body by saying, ‘This is My Body’ — that is, the ‘figure of My Body.’ A figure, however, there could not have been, unless there was in truth a body. Some empty thing, which is a phantasm, were not able to satisfy a figure. Or, if He pretended that bread were His Body, because in truth He lacked a body, then he must have given bread for us. It would support the vanity of Marcion, had bread been crucified! But why call His Body bread, and not rather a pumpkin, which Marcion had in place of a brain! Marcion did not understand how ancient is that figure of the Body of Christ, who said Himself through Jeremias: ‘They have devised a device against Me, saying, “Come, let us throw wood onto his bread,”’ — the cross, of course, upon His Body.” (Tertullian, Against Marcion, 4:30:3)
Origen – Anti-Transubstantiation
Against understanding John 6 “to the letter”
“If ye are the children of the church, if ye are well embued with the mysteries of the Gospel, and if the Word made flesh dwelleth in you, acknowledge what I say, because it is of the Lord, lest, not knowing it, you may not be known by him. Acknowledge that some things written in the holy books are figures, and therefore examine and understand the things which are said, as spiritual men : for if you receive them as carnal men, they injure you. There is in the New Testament a letter which killeth him who does not understand spiritually the things which are said. For if you take this according to the letter, Except ye eat my flesh and drink my blood, this letter killeth” — (Origen, Homily 7, on the 10th chap, of Leviticus)
The Bread and Wine are types and symbols
“Now, if ‘everything that entereth into the mouth goes into the belly and is cast out into the drought,’ even the meat which has been sanctified through the word of God and prayer, in accordance with the fact that it is material, goes into the belly and is cast out into the draught, but in respect of the prayer which comes upon it, according to the proportion of the faith, becomes a benefit and is a means of clear vision to the mind which looks to that which is beneficial, and it is not the material of the bread but the word which is said over it which is of advantage to him who eats it not unworthily of the Lord. And these things indeed are said of the typical and symbolical body. But many things might be said about the Word Himself who became flesh, and true meat of which he that eateth shall assuredly live for ever, no worthless person being able to eat it; for if it were possible for one who continues worthless to eat of Him who became flesh. who was the Word and the living bread, it would not have been written, that ‘every one who eats of this bread shall live for ever.’” (Origen, Commentary on Mathew 11:14)
The bread and wine are images, symbols, commended as a memory to his disciples:
“But if, as these affirm, he had neither flesh nor blood, of what flesh and of what body and of what blood are the bread and cup which he delivered the images ? by these symbols he commended his memory to his disciples.” (Origen, The third Dialogue against the Marcionites)
Most importantly:
Jesus Christ - Anti-transubstantiation
The blood in the cup still wine, which He will drink again when reunited with the Apostles in Heaven:
Mat 26:27-29 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; (28) For this is my blood of the new testament, which is shed for many for the remission of sins. (29) But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father’s kingdom.
Ready to be proven wrong.
Justin Martyr-
“This food we call the Eucharist, of which no one is allowed to partake except one who believes that the things we teach are true, and has received the washing for forgiveness of sins and for rebirth, and who lives as Christ handed down to us. For we do not receive these things as common bread or common drink; but as Jesus Christ our Savior being incarnate by God’s Word took flesh and blood for our salvation, so also we have been taught that the food consecrated by the Word of prayer which comes from him, from which our flesh and blood are nourished by transformation, is the flesh and blood of that incarnate Jesus.”-”First Apology”, Ch. 66, inter A.D. 148-155
Clement of Alexandria-”The Word is everything to a child: both Father and Mother, both Instructor and Nurse. ‘Eat My Flesh,’ He says, ‘and drink My Blood.’ The Lord supplies us with these intimate nutrients. He delivers over His Flesh, and pours out His Blood; and nothing is lacking for the growth of His children. O incredible mystery!”,-”The Instructor of the Children” [1,6,41,3] ante
Irenaeus -”So then, if the mixed cup and the manufactured bread receive the Word of God and become the Eucharist, that is to say, the Blood and Body of Christ, which fortify and build up the substance of our flesh, how can these people claim that the flesh is incapable of receiving God’s gift of eternal life, when it is nourished by Christ’s Blood and Body and is His member? As the blessed apostle says in his letter to the Ephesians, ‘For we are members of His Body, of His flesh and of His bones’ (Eph. 5:30). He is not talking about some kind of ‘spiritual’ and ‘invisible’ man, ‘for a spirit does not have flesh an bones’ (Lk. 24:39). No, he is talking of the organism possessed by a real human being, composed of flesh and nerves and bones. It is this which is nourished by the cup which is His Blood, and is fortified by the bread which is His Body. The stem of the vine takes root in the earth and eventually bears fruit, and ‘the grain of wheat falls into the earth’ (Jn. 12:24), dissolves, rises again, multiplied by the all-containing Spirit of God, and finally after skilled processing, is put to human use. These two then receive the Word of God and become the Eucharist, which is the Body and Blood of Christ.”-”Five Books on the Unmasking and Refutation of the Falsely Named Gnosis”. Book 5:2, 2-3, circa 180 A.D.
Tertullian-”Then, having taken the bread and given it to His disciples, He made it His own body, by saying, ‘This is my body,’ that is, the figure of my body. A figure, however, there could not have been, unless there were first a veritable body…He did not understand how ancient was this figure of the body of Christ, who said Himself by Jeremiah: ‘I was like a lamb or an ox that is brought to the slaughter, and I knew not that they devised a device against me, saying, Let us cast the tree upon His bread,’ which means, of course, the cross upon His body. And thus, casting light, as He always did, upon the ancient prophecies, He declared plainly enough what He meant by the bread, when He called the bread His own body. He likewise, when mentioning the cup and making the new testament to be sealed ‘in His blood,’ affirms the reality of His body. For no blood can belong to a body which is not a body of flesh. If any sort of body were presented to our view, which is not one of flesh, not being fleshly, it would not possess blood. Thus, from the evidence of the flesh, we get a proof of the body, and a proof of the flesh from the evidence of the blood.” Tertullian, Against Marcion, 40 (A.D. 212).
