St. Ambrose of Milan The Patriarchs 9,38 190 A.D.
His poverty enriches, the fringe of His garment heals, His hunger satisfies, His death gives life, His burial gives resurrection. Therefore, He is a rich treasure, for His bread is rich. And ‘rich’ is apt for one who has eaten this bread will be unable to feel hunger. He gave it to the Apostles to distribute to a believing people, and today He gives it to us, for He, as a priest, daily consecrates it with His own words. Therefore, this bread has become the food of the saints.
St. Clement of Alexandria The Instructor 2,2,19,4 202 A.D.
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.
St. Clement of Alexandria The Instructor 1,6,41,3 202 A.D.
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
Tertullian Against Marcion 4,40,3 212 A.D.
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. An empty thing, or phantom, is incapable of a figure. If, however, (as Marcion might say,) He pretended the bread was His body, because He lacked the truth of bodily substance, it follows that He must have given bread for us. It would contribute very well to the support of Marcion’s theory of a phantom body, that bread should have been crucified! But why call His body bread, and not rather (some other edible thing, say) a melon, which Marcion must have had in lieu of a heart! 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.
As you can see above all of Christianity has taught this from the beginning, yet somehow under this new interpretation this is no longer the case.
If the apostles were incapable of transmitting this message, in particular John to Ignatius, to the first generations disciples then the gospel of John itself is suspect as it is at odds with their teachings to their disciples. So either they are wrong, or those who go scripture alone are incorrect.
