Scripture manifestly applying the terms bread and water to nothing else but to those heresies, which employ bread and water in the oblation, not according to the canon of the Church. For there are those who celebrate the Eucharist with mere water.
Clement of Alexandria
The Stromata, Book I
Chapter XIX
But since He said, “And the bread which I will give is My flesh,” and since flesh is moistened with blood, and blood is figuratively termed wine, we are bidden to know that, as bread, crumbled into a mixture of wine and water, seizes on the wine and leaves the watery portion, so also the flesh of Christ, the bread of heaven absorbs the blood; that is, those among men and into sympathy, in consequence of the nourishment which flows from the Word; and into immortality, through His guidance:
Clement of Alexandria
The Paedagogus, Book I
Chapter VI
Exert your will only, and you have overcome ruin; bound to the wood of the cross, thou shalt be freed from destruction: the word of God will be thy pilot, and the Holy Spirit will bring thee to anchor in the haven of heaven. Then shalt thou see my God, and be initiated into the sacred mysteries, and come to the fruition of those things which are laid up in heaven reserved for me, which “ear hath not heard, nor have they entered into the heart of any.”
Clement of Alexandria
Exhortation to the Heathen
Chapter XII
Those who have become acquainted with the secondary (i.e., under Christ) constitutions of the apostles, are aware that the Lord instituted a new oblation in the new covenant, according to [the declaration of] Malachi the prophet.
…For we make an oblation to God of the bread and the cup of blessing, giving Him thanks in that He has commanded the earth to bring forth these fruits for our nourishment. And then, when we have perfected the oblation, we invoke the Holy Spirit, that He may exhibit this sacrifice, both the bread the body of Christ, and the cup the blood of Christ, in order that the receivers of these antitypes may obtain remission of sins and life eternal.
Irenaeus of Lyons
Lost Writings
Fragment XXXVII
He promised to drink of the fruit of the vine with His disciples, 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.
Irenaeus of Lyons
Against Heresies, Book V
Chapter XXXIII
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.
Irenaeus of Lyons
Against Heresies, Book V
Chapter II
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 does 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.
Irenaeus of Lyons
Against Heresies, Book V
Chapter II
so did the Word give to the people that very precept as to the making of oblations, although He stood in no need of them, that they might learn to serve God: thus is it, therefore, also His will that we, too, should offer a gift at the altar, frequently and without intermission.
Irenaeus of Lyons
Against Heresies, Book IV
Chapter XVIII
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.
Irenaeus of Lyons
Against Heresies, Book IV
Chapter XVIII
For some, by maintaining that the Father is different from the Creator, do, when they offer to Him what belongs to this creation of ours, set Him forth as being covetous of another’s property, and desirous of what is not His own.
Those, again, who maintain that the things around us originated from apostasy, ignorance, and passion, do, while offering unto Him the fruits of ignorance, passion, and apostasy, sin against their Father, rather subjecting Him to insult than giving Him thanks.
Irenaeus of Lyons
Against Heresies, Book IV
Chapter XVIII
