To the Ephesians
For if I in this brief space of time, have enjoyed such fellowship with your bishop–I mean not of a mere human, but of a spiritual nature–how much more do I reckon you happy who are so joined to him as the Church is to Jesus Christ, and as Jesus Christ is to the Father, that so all things may agree in unity! Let no man deceive himself: if any one be not within the altar, he is deprived of the bread of God. For if the prayer of one or two possesses such power, how much more that of the bishop and the whole Church! He, therefore, that does not assemble with the Church, has even by this manifested his pride, and condemned himself. For it is written, “God resisteth the proud.” Let us be careful, then, not to set ourselves in opposition to the bishop, in order that we may be subject to God. (Chapter 5)
If Jesus Christ shall graciously permit me through your prayers, and if it be His will, I shall, in a second little work which I will write to you, make further manifest to you [the nature of] the dispensation of which I have begun [to treat], with respect to the new man, Jesus Christ, in His faith and in His love, in His suffering and in His resurrection. Especially [will I do this if the Lord make known to me that ye come together man by man in common through grace, individually, in one faith, and in Jesus Christ, who was of the seed of David according to the flesh, being both the Son of man and the Son of God, so that ye obey the bishop and the presbytery with an undivided mind, breaking one and the same bread, which is the medicine of immortality, and the antidote to prevent us from dying, but [which causes] that we should live for ever in Jesus Christ. (Chapter 20)
To the Philadelphians
Take ye heed, then, to have but one Eucharist. For there is one flesh of our Lord Jesus Christ, and one cup to [show forth] the unity of His blood; one altar; as there is one bishop, along with the presbytery and deacons, my fellow-servants: that so, whatsoever ye do, ye may do it according to [the will of] God. (Chapter 4)
To the Smyrnaeans
They abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Saviour Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again. Those, therefore, who speak against this gift of God, incur death in the midst of their disputes. But it were better for them to treat it with respect, that they also might rise again. It is fitting, therefore, that ye should keep aloof from such persons, and not to speak of them either in private or in public, but to give heed to the prophets, and above all, to the Gospel, in which the passion [of Christ] has been revealed to us, and the resurrection has been fully proved. But avoid all divisions, as the beginning of evils. (Chapter 7)
Justin Martyr (110-165)
And this food is called among us Eukaristia [the Eucharist], of which no one is allowed to partake but the man who believes that the things which we teach are true, and who has been washed with the washing that is for the remission of sins, and unto regeneration, and who is so living as Christ has enjoined. For not as common bread and common drink do we receive these; but in like manner as Jesus Christ our Saviour, having been made flesh by the Word of God, had both flesh and blood for our salvation, so likewise have we been taught that the food which is blessed by the prayer of His word, and from which our blood and flesh by transmutation are nourished, is the flesh and blood of that Jesus who was made flesh. For the apostles, in the memoirs composed by them, which are called Gospels, have thus delivered unto us what was enjoined upon them; that Jesus took bread, and when He had given thanks, said, “This do ye in remembrance of Me, this is My body;” and that, after the same manner, having taken the cup and given thanks, He said, “This is My blood;” and gave it to them alone. Which the wicked devils have imitated in the mysteries of Mithras, commanding the same thing to be done. For, that bread and a cup of water are placed with certain incantations in the mystic rites of one who is being initiated, you either know or can learn. (Chapter 66)
Dialogue of Justin with Trypho
And the offering of fine flour, sirs,” I said, “which was prescribed to be presented on behalf of those purified from leprosy, was a type of the bread of the Eucharist, the celebration of which our Lord Jesus Christ prescribed, in remembrance of the suffering which He endured on behalf of those who are purified in soul from all iniquity, in order that we may at the same time thank God for having created the world, with all things therein, for the sake of man, and for delivering us from the evil in which we were, and for utterly overthrowing principalities and powers by Him who suffered according to His will. Hence God speaks by the mouth of Malachi, one of the twelve [prophets], as I said before, about the sacrifices at that time presented by you: ‘I have no pleasure in you, saith the Lord; and I will not accept your sacrifices at your hands: for, from the rising of the sun unto the going down of the same, My name has been glorified among the Gentiles, and in every place incense is offered to My name, and a pure offering: for My name is great among the Gentiles, saith the Lord: but ye profane it.’ He then speaks of those Gentiles, namely us, who in every place offer sacrifices to Him, i.e., the bread of the Eucharist, and also the cup of the Eucharist, affirming both that we glorify His name, and that you profane. The command of circumcision, again, bidding [them] always circumcise the children on the eighth day, was a type of the true circumcision, by which we are circumcised from deceit and iniquity through Him who rose from the dead on the first day after the Sabbath, [namely through] our Lord Jesus Christ. For the first day after the Sabbath, remaining the first of all the days, is called, however, the eighth, according to the number of all the days of the cycle, and [yet] remains the first. (Chapter 41)
Against Heresies, Book 4:
But how can they be consistent with themselves, [when they say] that the bread over which thanks have been given is the body of their Lord, and the cup His blood, if they do not call Himself the Son of the Creator of the world, that is, His Word, through whom the wood fructifies, and the fountains gush forth, and the earth gives “first the blade, then the ear, then the full corn in the ear.” (Chapter 18:4)
Then, again, how can they say that the flesh, which is nourished with the body of the Lord and with His blood, goes to corruption, and does not partake of life? Let them, therefore, either alter their opinion, or cease from offering the things just mentioned. 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. (Chapter 18:5)
Against Heresies, Book 5
But vain in every respect are they who despise the entire dispensation of God, and disallow the salvation of the flesh, and treat with contempt its regeneration, maintaining that it is not capable of incorruption. But if this indeed do not attain salvation, then neither did the Lord redeem us with His blood, nor is the cup of the Eucharist the communion of His blood, nor the bread which we break the communion of His body. For blood can only come from veins and flesh, and whatsoever else makes up the substance of man, such as the Word of God was actually made. By His own blood he redeemed us, as also His apostle declares, “In whom we have redemption through His blood, even the remission of sins.” And as we are His members, we are also nourished by means of the creation (and He Himself grants the creation to us, for He causes His sun to rise, and sends rain when He wills). He has acknowledged the cup (which is a part of the creation) as His own blood, from which He bedews our blood; and the bread (also a part of the creation) He has established as His own body, from which He gives increase to our bodies. (Chapter 2:2)
When, therefore, the mingled cup and the manufactured bread receives the Word of God, and the Eucharist of the blood and the body of Christ is made, from which things the substance of our flesh is increased and supported, how can they affirm that the flesh is incapable of receiving the gift of God, which is life eternal, which [flesh] is nourished from the body and blood of the Lord, and is a member of Him? — even as the blessed Paul declares in his Epistle to the Ephesians, that “we are members of His body, of His flesh, and of His bones.” He does not speak these words of some spiritual and invisible man, for a spirit has not bones nor flesh; but [he refers to] that dispensation [by which the Lord became] an actual man, consisting of flesh, and nerves, and bones — that [flesh] which is nourished by the cup which is His blood, and receives increase from the bread which is His body. And just as a cutting from the vine planted in the ground fructifies in its season, or as a corn of wheat falling into the earth and becoming decomposed, rises with manifold increase by the Spirit of God, who contains all things, and then, through the wisdom of God, serves for the use of men, and having received the Word of God, becomes the Eucharist, which is the body and blood of Christ; so also our bodies, being nourished by it, and deposited in the earth, and suffering decomposition there, shall rise at their appointed time, the Word of God granting them resurrection to the glory of God, even the Father, who freely gives to this mortal immortality, and to this corruptible incorruption, because the strength of God is made perfect in weakness, in order that we may never become puffed up, as if we had life from ourselves, and exalted against God, our minds becoming ungrateful; (Chapter 2:3)
Clement of Alexandria (153-217)
The Instructor, Book 1
The Word is all to the child, both father and mother and tutor and nurse. “Eat ye my flesh,” He says, “and drink my blood.” Such is the suitable food which the Lord ministers, and He offers His flesh and pours forth His blood, and nothing is wanting for the children’s growth. O amazing mystery l We are enjoined to cast off the old and carnal corruption, as also the old nutriment, receiving in exchange another new regimen, that of Christ, receiving Him if we can, to hide Him within; and that, enshrining the Saviour in our souls, we may correct the affections of our flesh. (Chapter 6)
The Instructor, Book 2
And the blood of the Lord is twofold. For there is the blood of His flesh, by which we are redeemed from corruption; and the spiritual, that by which we are anointed. And to drink the blood of Jesus, is to become partaker of the Lord’s immortality; the Spirit being the energetic principle of the Word, as blood is of flesh.
Accordingly, as wine is blended with water, so is the Spirit with man. And the one, the mixture of wine and water, nourishes to faith; while the other, the Spirit, conducts to immortality.
And the mixture of both–of the water and of the Word–is called Eucharist, renowned and glorious grace; and they who by faith partake of it are sanctified both in body and soul. For the divine mixture, man, the Father’s will has mystically compounded by the Spirit and the Word. For, in truth, the spirit is joined to the soul, which is inspired by it; and the flesh, by reason of which the Word became flesh, to the Word. (Chapter 2)
Who is the Rich Man Who Shall be Saved?
For I will bring thee to a rest of ineffable and unutterable blessings, which eye hath not seen, nor ear heard, nor have entered into the heart of men; into which angels desire to look, and see what good things God hath prepared for the saints and the children who love Him.” I am He who feeds thee, giving Myself as bread, of which he who has tasted experiences death no more, and supplying day by day the drink of immortality. (Chapter 23)
On the Resurrection of the Flesh
The flesh, indeed, is washed, in order that the soul may be cleansed; the flesh is anointed, that the soul may be consecrated; the flesh is signed (with the cross), that the soul too may be fortified; the flesh is shadowed with the imposition of hands, that the soul also maybe illuminated by the Spirit; the flesh feeds on the body and blood of Christ, that the soul likewise may fatten on its God. (Chapter 8)
The Extant Works and Fragments: Exegetical
Another Fragment – And again, “And to those that want understanding she said”–that is, to those who have not yet obtained the power of the Holy Ghost–“Come, eat of my bread, and drink of the wine which I have mingled for you;” by which is meant, that He gave His divine flesh and honoured blood to us, to eat and to drink it for the remission of sins.
Epistles of Cyprian
For we must comply with fitting intimations and admonitions, that the sheep may not be deserted in danger by the shepherds, but that the whole flock may be gathered together into one place, and the Lord’s army may be arrived for the contest of the heavenly warfare. For the repentance of the mourners was reasonably prolonged for a more protracted time, help only being afforded to the sick in their departure, so long as peace and tranquility prevailed, which permitted the long postponement of the tears of the mourners, and late assistance in sickness to the dying. But now indeed peace is necessary, not for the sick, but for the strong; nor is communion to be granted by us to the dying, but to the living, that we may not leave those whom we stir up and exhort to the battle unarmed and naked, but may fortify them with the protection of Christ’s body and blood. And, as the Eucharist is appointed for this very purpose that it may be a safeguard to the receivers, it is needful that we may arm those whom we wish to be safe against the adversary with the protection of the Lord’s abundance. For how do we teach or provoke them to shed their blood in confession of His name. if we deny to those who are about to enter on the warfare the blood of Christ? Or how do we make them fit for the cup of martyrdom, if we do not first admit them to drink, in the Church, the cup of the Lord by the right of communion? (Epistle 53:2)
