“I desire the bread of God, the heavenly bread, the bread of life, which is the flesh of Jesus Christ, the Son of God, who became afterwards of the seed of David and Abraham; and I desire the drink of God, namely His blood, which is incorruptible love and eternal life.”
— Ignatius of Antioch (105)
Letter to the Romans, Chapter 7
“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.”
— Justin Martyr (160)
First Apology, Chapter 66
“He has declared the cup, a part of creation, to be his own blood, from which he causes our blood to flow; and the bread, a part of creation, he has established as his own body, from which he gives increase to our bodies. When, therefore, the mixed cup [wine and water] 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 say that the flesh is not capable of receiving the gift of God, which is eternal life—flesh which is nourished by the body and blood of the Lord, and is in fact a member of him?”
— Irenaeus (180)
Against Heresies, Book 5, Chapter 2, Verses 2–3
“Consider therefore the Bread and the Wine not as bare elements, for they are, according to the Lord’s declaration, the Body and Blood of Christ; for even though sense suggests this to you, yet let faith establish you. Judge not the matter from the taste, but from faith be fully assured without misgiving, that the Body and Blood of Christ have been vouchsafed to you.”
— Cyril of Jerusalem (313–386)
Catechetical Lectures, Lecture 22, Paragraph 6
“Perhaps you will say, I see something else, how is it that you assert that I receive the Body of Christ? And this is the point which remains for us to prove. And what evidence shall we make use of? Let us prove that this is not what nature made, but what the blessing consecrated, and the power of blessing is greater than that of nature, because by blessing nature itself is changed.”
— Ambrose of Milan (339–397)
On the Mysteries, Chapter 9, Paragraph 50
“The Lord Jesus Himself proclaims: This is My Body. Matthew 26:26 Before the blessing of the heavenly words another nature is spoken of, after the consecration the Body is signified. He Himself speaks of His Blood. Before the consecration it has another name, after it is called Blood. And you say, Amen, that is, It is true. Let the heart within confess what the mouth utters, let the soul feel what the voice speaks.”
— Ambrose of Milan (339–397)
On the Mysteries, Chapter 9, Paragraph 54
