Because Scripture is explicit about the implicit change in that the substance of normal bread is now substantially Jesus, True God, medieval comparisons to alchemy, chemistry or any natural science are inappropriate.
Jesus took bread, said the blessing, broke it and giving it to His disciples said,
“Take and eat; this is My Body.” (Matthew 26: 26-28)
Here’s where all disagree with the post Council of Trent Catholic Church…
There might be some interesting hermeneutics of the words “change” “transmutates” “becomes” "converts’ in the Eucharistic texts. The thing is, none of those words exist in any of those texts.
What the texts clearly state is “is.” “Is” indicates being, existence - the verb has nothing to do with conversion or change.
Remember too: Jesus and Paul speak of bread and wine AFTER the consecration, in the case of Paul, FAR more than before the consecration. I think the new, unique Catholic “take” on this might be at least theoretically possible if that were not the case. But, as it is, the min. required is for The Catholic Church to do EXACTLY as Zwingli did (in the opposite direction) - somehow embrace a “split half is/ half isn’t” interpretation - each without any textual support or indication. IMHO, there’s no difference in the hermeneutic of Zwingli or of The Catholic Church in this regard - you’d just chosen different words to arbitralily take literally or symbolicly (or at least less than literal).
The second misunderstanding of Catholic Transubstantiation involves the misuse of metaphysical terms.
Western, medieval, Catholic Scholasticism largely embraced the idea of merging the popular secular ideas of the day with Christian theology in hopes of explaining things. Alchemy’s central theme, it’s foundational concept was known by a very technical, very precise term: transubstantiation. It was the idea that a substance can be fundamentally converted from one thing to another (yes, lead to gold was the goal of those that believed this theory) - it was all the rage when the theory of Transubstantiation in the Eucharist was invented.
Accident was also a very precise, technical term from Aristotle. Basically, it means that a reality may have properties entirely unrelated to it. My physics prof called it “ghost physics” (his term), that properties may be unrelated to physics (as we think of it) - so that I might look in the mirror and see some male super model instead, lol. Again, these were very technical, precise terms - used by Catholic Scholastics in coming up with this new theory (centuries later made dogma).
Again, Lutherans, Oriental Orthodox, Eastern Orthodox and Catholics before 1215 were and are comfortable with the term “change” - since such simply indicates that a change happened. But that has NOTHING REMOTELY to suggest any transubstantiation leaving behind Aristotelian accidents! Change just means change, lol. There IS a change, because the nice ladies put bread and wine up there and we receive CHRIST! Is that not change!!! But it has NOTHING REMOTELY to do with Transubstantiation or alchemy or Aristotle or accidents - and requires no “explaining away” of what Jesus said or Paul penned (as Zwingli and post Trent Catholics need to do).
Again, Lutherans stick with Real Presence. Powerfully, passionately, faithfully. It is the embrace of EXACTLY what the Eucharistic texts say. Literally. Fully. Just as the Father’s proclaimed as they do embraced the words. Real Presense affirms that the meaning of is is is. IS has to do with being, existence - so Christ IS present. His real Body. His real Blood. True - it doesn’t DENY what Jesus said and Paul penned, “bread” and “wine” AFTER the Consecration - it just doesn’t care (to be blunt). I honestly don’t know WHY (historically or theologically) WHY The Catholic Church alone is so very, very fasinated - to the point of needing dogma - in that tasteless wafer and non-inspiring wine WHEN CHRIST IS THERE! To Lutherans, the point is CHRIST. This is a Sacrament of Christ, of His grace and mercy, His power and forgiveness, His presence! It’s not about alchemy or Aristotle. I just see this medieval attempt to merge two pop ideas of the day (long, long ago rejected) with the Holy Eucharist as accomplishing anything other than to direct our attention away from Christ and to moot speculations about words that don’t even appear in the text, AND it gets The Catholic Church into the same “problem” that Zwingli Protestants get into: how to justify their entirely untextual “split” half literal/ half symbolic interpretation of the texts.
Now, I don’t denounce it. I don’t actually regard ANY official Catholic dogma to be heresy. But I find this one entirely unsubstantiated - by Scripture or Tradition, unnecessary, hermeneutically problematic, and maybe most of all - distracting. THAT SAID, spiritually, we are twins. Lutherans, Oriental Orthodox, Eastern Orthodox and many Anglicans may disagree with Catholics on Transubstantiation - but we all agree on Real Presence. We are passionate about that and it forms a deep, rich part of our Christian spirituality. Kinda sad this bit of medieval speculation over words that don’t even exists divides us - but MUCH, MUCH unites us on THIS point. IMHO, we are FAR closer on the Eucharist than Lutherans are with most Protestants.
