Pagan accusations (reported by Athenagoras)

Pagan Romans accused Christians of eating their god and drinking human blood in their rituals.

Roman pagans accused Christians of literal cannibalism — which only makes sense if the Christians themselves claimed to be eating actual flesh and blood. No pagan accused them of eating a symbol.

1 Corinthians 11:27–29

Whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the Body and Blood of the Lord.

Paul teaches that unworthy reception is a sin against the actual Body and Blood — not against a symbol. You cannot sin against a symbol.

Didache 9–10

Let no one eat or drink of your Eucharist but those who have been baptised in the name of the Lord; for the Lord has spoken: Do not give what is holy to dogs.

The earliest non-scriptural Christian document treats the Eucharist as something holy in itself — not merely a symbolic ritual.

Letter to the Smyrnaeans VI

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.

The earliest explicit patristic statement on the Real Presence. Ignatius identifies denial of the Real Presence as a mark of heresy, written within a decade of the Apostle John's death.

Letter to the Smyrnaeans 6–7

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.

The position Luther defended in 1529 was the position Ignatius attested in AD 107 — 1,422 years earlier. Luther was not recovering a lost doctrine. He was defending an unbroken tradition against a Reformation novelty.

Letter to the Smyrnaeans 7

They abstain from the Eucharist and from prayer, because they do not confess that the Eucharist is the flesh of our Saviour Jesus Christ.

Ignatius identifies denial of the Real Presence as the defining mark of the Docetist heresy. The Real Presence is the orthodox position; symbolism is the heresy.

Didache XIV

On the Lord's Day, gather together and break bread and give thanks, having first confessed your transgressions, that your sacrifice may be pure… For this is what was spoken by the Lord: In every place and time offer me a pure sacrifice.

The earliest known Christian liturgical document explicitly calls the Eucharist a sacrifice and applies Malachi 1:11 to it.

First Apology 66

We do not receive these as common bread and common drink; but… this food which is blessed by the prayer of His word… is the flesh and blood of that Jesus who was made flesh.

Justin, writing to defend Christianity to the Roman Emperor, explains exactly what the Eucharist is. He does not call it a symbol.

First Apology LXV-LXVI

We do not receive these gifts as ordinary food or drink. Just as Jesus Christ our Saviour was made flesh by the word of God, so we are taught that the food over which prayer of the word of God has been offered is the flesh and blood of that same incarnate Jesus.

Justin, writing to the pagan Roman emperor to explain Christianity, uses incarnational language: the food is the flesh of the incarnate Jesus — not a symbol.

Dialogue with Trypho XLI

The offering of fine flour was a type of the bread of the Eucharist... which Jesus Christ our Lord commanded us to offer in remembrance of the body which he assumed... and concerning this sacrifice Malachi prophesied.

Justin applies the Malachi prophecy directly to the Eucharist and calls it a sacrifice offered by Gentile Christians in fulfilment of Old Testament prophecy.

Against Heresies V.2.2

When the mingled cup and the baked bread receives the Word of God and becomes the Eucharist — the body of Christ — and from these the substance of our flesh is increased and supported, how can they deny that the flesh is capable of receiving the gift of God?

Irenaeus uses the Real Presence as a theological argument against Gnostic dualism: if Christ's body is truly in the Eucharist and nourishes our flesh, our flesh must be capable of resurrection.

Against Heresies IV.17.5

The offering of the Church, which the Lord gave instructions to be offered in the whole world, is accounted with God a pure sacrifice and is acceptable to him.

Irenaeus, independently of Justin, identifies the Church's Eucharistic offering as the pure sacrifice of Malachi 1:11.

Against Heresies V.2.3

The bread over which thanks have been given is the Body of their Lord, and the cup is His Blood.

Irenaeus uses the Real Presence as an argument against Gnosticism — if the body is evil, you cannot receive the Body of Christ as food.

Homilies on Exodus XIII.3

You who are accustomed to take part in the divine mysteries know, when you receive the body of the Lord, how you protect it with all caution and veneration lest any small part fall from it, lest anything of the consecrated gift be lost.

Origen instructs his congregation to protect the Eucharistic bread with extreme care — the behaviour appropriate to the body of the Lord, not to a symbol.

Letter 63

The passion of the Lord is the sacrifice which we offer. For what we offer in the sacrifice is Christ — the priest offers truly in the place of Christ.

Cyprian makes the connection between the Mass and Calvary explicit: the priest offers Christ in the place of Christ.

Mystagogical Catecheses IV.3

Do not, therefore, regard the bread and wine as simply that, for they are, according to the Master's declaration, the body and blood of Christ. Even though the senses suggest to you the other, let faith make you firm.

Cyril, instructing newly baptised Christians, tells them explicitly to override the evidence of their senses and believe that the bread and wine are the body and blood of Christ.

Catechetical Lectures 22

Since He Himself has declared and said of the Bread, This is My Body, who shall dare to doubt any longer? Since He has affirmed and said, This is My Blood, who shall ever hesitate and say it is not His Blood?

Cyril, instructing catechumens in Jerusalem, treats the Real Presence as the settled, unquestionable teaching of the Church.

On the Mysteries 9.52

That bread is bread before the words of the Sacraments; when consecration has taken place, from being bread it becomes the Flesh of Christ.

Ambrose explicitly describes the change that occurs at consecration — bread becomes Flesh. This is transubstantiation in all but name.

On the Mysteries IX.50

You say: My bread is ordinary. But that bread is bread before the words of the sacraments; when consecration takes place, the bread becomes the body of Christ.

Ambrose describes a transformation of the bread — not a change of significance but a change of substance — effected by the words of consecration.

Sermon 227

That bread which you see on the altar, sanctified by the word of God, is the Body of Christ. That chalice — sanctified by the word of God, is the Blood of Christ.

Augustine, the most influential theologian in Christian history, teaches the Real Presence plainly to newly baptised Christians.

Homilies on Hebrews XVII.3

We do not offer a different sacrifice like the high priest of old, but the same always; or rather we make a memorial of the sacrifice. For there is one sacrifice... He who offered is the same who now offers by the ministry of the priests.

Chrysostom identifies the Eucharist as one sacrifice, not many — the same sacrifice of Calvary made present through the ministry of priests.

Homilies on 1 Corinthians XXIV.4

What then? Do we not offer every day? We offer indeed, but making a remembrance of His death, and this is one and not many sacrifices.

Chrysostom distinguishes the many celebrations from the one sacrifice — the same insight the Council of Trent later defined.

Against the Fanatics

Even if a hundred thousand devils, together with all fanatics, should rush forward crying, "Bread, bread!" I will die on this confession: in the Lord's Supper the true body and blood of Jesus Christ are eaten and drunk.

The vehemence is directed not at Catholics but at Zwingli and the Swiss reformers. Luther's language about the Eucharist is more forceful in defending the Real Presence than most Catholic apologetics. LW 40:213.

Confession Concerning Christ's Supper

I confess that in the Supper of our Lord Jesus Christ the true body and blood are orally eaten and drunk in the bread and wine, even by unworthy persons.

Written seven years after the Diet of Worms — Luther never wavered on this point. His eucharistic theology is closer to Catholicism than to Reformed Christianity. LW 37:161.

Report of the Marburg Colloquy

Luther wrote HOC EST CORPUS MEUM on the tablecloth and refused throughout the colloquy to allow the words to be treated as metaphor. "I will not argue the case; the text is here. I cannot pass over it."

Sola Scriptura produced two diametrically opposed readings of the same four words within 12 years of the 95 Theses. Luther kept the Catholic reading. Zwingli denied it. Calvin found a third position. The principle that was supposed to unify Christian doctrine on Scripture immediately fragmented it.
