Well, that's your interpretation; as you can see, Eliyahu interprets the ECFs differently and more ambiguously and, for once, I'm inclined to agree with him

. That's why I said earlier that I'm happy to be agnostic on the subject of exactly
how Christ is Really Present in communion (physically? spiritually? both?) - that's a matter for God; all I know is that in receiving the bread and wine, I receive Jesus - and He receives me. I'm more than happy to leave it at that.
If the ECF's reiterated what Jesus said, thousand times of repetition don't change the interpretation.
If ECF's stated more than what Jesus said, it means that they were wrong with the human words.
I don't think they meant their interpretations by the Human Body Butcher house or they had overrode the commandments of the OT prohibiting the Eating of Blood in any manner.
If ECF's claimed that the physical substances are changed to new ones, i.e. flesh and blood, they must have mentioned any specific process where the materials are changed. For example, from the bakery or during the process of prayer, etc.
Also, we already notice that ECF started to deviate from the NT teachings when Clement mentioned about the clergy systems. So, many teachings went apostate already as Paul warned to Ephesian elders ( Acts 20:28-30) " Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them "
I don't think any ECF's clearly stated that they eat Blood despite the prohibition by OT.
The concept of Eating Blood emerged only after 12c and after the following Thomas Acquinas and Lateran Council, unknowingly the Great Principle of Sacrifice to God.
If one say that they ate the Blood as a symbol of accepting the sacrifice next day at the Cross, then there are two contradictions there.
One is that they accepted "Symbolism", and the other is that they drank the Blood while they still believed that the Blood was for God as a redemption. In such case, it is like that Israelites drank blood at the same time while they applied the blood of lambs on the door posts and on the lintels. We don't read such statements except that the BLood eating was prohibited.
On the Yom-Kipur, only the Blood was brought into the Holy of Holies, only by the High Priest, which indicates the Blood was more important than the body of the sacrifice, because the life of the animal was there. Actually Blood is the media of the life to the body. So, the Blood was offered as a confession that the sinner died before the presence of God, and thereby the forgiveness was given to the sinners.
If the sinners drank the blood, it doesn't mean that Blood was offered to God. Throughout OT we don't find any statements that the people drank blood.
Even in NT we are supposed to abstain from Blood ( Acts 15:20). God saw the Blood of Jesus at the Cross, and He accepted it as a Redemption for those who believe in the Blood, and for the whole world.
In remembrance of such Blood, we take the cup, but it doesn't mean that we drink the blood as we read the followings:
1 Cor 11
26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
Paul never said Flesh or Blood here.
Jesus is everywhere in the world, and the bread and wine are special to commemorate the Lord, but it doesn't mean that the Bread itself has ears and eyes, and the wine has the heart to beat out the blood.
The main point of the Supper is that we have such faith and belief, we believe what Jesus has done at the Cross, He died for us by shedding the Blood at the Cross.
We must notice the words in the following too:
1 Cor 10:16 The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
The word for Communion here is the translation from Koinonia, which has the meanings of " fellowship, partnership, participation, contribution, aid, etc"
How come it is abused as " Eating Blood" ?
Doesn't it mean " Participation" by remembering and believing what Jesus has done at the Cross and the Blood shed at the Cross?
Can we imagine that Jewish believers at the time of Jesus ate the Blood despite the OT commandments?
If they had so, they would have been extremely condemned for it by the other Jews.
If they did't drink Blood, then it means that they just commemorated His Blood with the wine, which is either Symbolism or Memorialism or Remembrance-ism.
