The problem you have is it is not ONLY figurative or symbolic. This is the Fundamentalist problem. Why can something not be both a symbol and literal? It can and it does.
You dismiss a ton of what he says by saying it’s only figurative. He clearly states otherwise and adds a figurative element to it.
Further , your statement that this was not part of Catholicism until the 1200’s or even 800 is patently false.
I showed you evidence from the first century and there are countless other sources from the first 500 years.

Council of Nicaea (c. 325 A.D.)
It has come to the attention of the holy and great council that in some localities and cities deacons give the Eucharist to presbyters, although neither the canon nor the custom permits those who do NOT offer sacrifice to give the Body of Christ to those who do offer the sacrifice… (Canon 18)
St. Ephraim (c. 306 - 373 A.D.)
Our Lord Jesus took in His hands what in the beginning was only bread; and He blessed it, and signed it, and made it holy in the name of the Father and in the name of the Spirit; and He broke it and in His gracious kindness He distributed it to all His disciples one by one. He called the bread His living Body, and did Himself fill it with Himself and the Spirit. And extending His hand, He gave them the Bread which His right hand had made holy: “Take, all of you eat of this, which My word has made holy. Do not now regard as bread that which I have given you; but take, eat this Bread [of life], and do not scatter the crumbs; for what I have called My Body, that it is indeed. One particle from its crumbs is able to sanctify thousands and thousands, and is sufficient to afford life to those who eat of it. Take, eat, entertaining no doubt of faith, because this is My Body, and whoever eats it in belief eats in it Fire and Spirit. But if any doubter eat of it, for him it will be only bread. And whoever eats in belief the Bread made holy in My name, if he be pure, he will be preserved in his purity; and if he be a sinner, he will be forgiven.” But if anyone despise it or reject it or treat it with ignominy, it may be taken as a certainty that he treats with ignominy the Son, who called it and actually made it to be His Body.
After the disciples had eaten the new and holy Bread, and when they understood by faith that they had eaten of Christ’s body, Christ went on to explain and to give them the whole Sacrament. He took and mixed a cup of wine. Then He blessed it, and signed it, and made it holy, declaring that it was His own Blood, which was about to be poured out…Christ commanded them to drink, and He explained to them that the cup which they were drinking was His own Blood: “This is truly My Blood, which is shed for all of you. Take, all of you, drink of this, because it is a new covenant in My Blood. As you have seen Me do, do you also in My memory. Whenever you are gathered together in My name in Churches everywhere, do what I have done, in memory of Me. Eat My Body, and drink My Blood, a covenant new and old.” (Homilies 4:4; 4:6)
St. Athanasius (c. 295 - 373 A.D.)
You shall see the Levites bringing loaves and a cup of wine, and placing them on the table. So long as the prayers of supplication and entreaties have not been made, there is only bread and wine. But after the great and wonderful prayers have been completed, then the bread is become the Body, and the wine the Blood, of our Lord Jesus Christ….Let us approach the celebration of the mysteries. This bread and this wine, so long as the prayers and supplications have not taken place, remain simply what they are. But after the great prayers and holy supplications have been sent forth, the Word comes down into the bread and wine – and thus is His Body confected. (Sermon to the Newly Baptized, from Eutyches)
St. Augustine (c. 354 - 430 A.D.)
“That Bread which you see on the altar, having been sanctified by the word of God IS THE BODY OF CHRIST. That chalice, or rather, what is in that chalice, having been sanctified by the word of God, IS THE BLOOD OF CHRIST. Through that bread and wine the Lord Christ willed to commend HIS BODY AND BLOOD, WHICH HE POURED OUT FOR US UNTO THE FORGIVENESS OF SINS.” (Sermons 227)
“The Lord Jesus wanted those whose eyes were held lest they should recognize him, to recognize Him in the breaking of the bread [Luke 24:16,30-35]. The faithful know what I am saying. They know Christ in the breaking of the bread. For not all bread, but only that which receives the blessing of Christ, BECOMES CHRIST’S BODY.” (Sermons 234:2)
“What you see is the bread and the chalice; that is what your own eyes report to you. But what your faith obliges you to accept is that THE BREAD IS THE BODY OF CHRIST AND THE CHALICE [WINE] THE BLOOD OF CHRIST.” (Sermons 272)
