The faithful from the beginning have had to contend with the teaching that the bread and wine are changed into the body and blood of Christ, into the entirety of Christ. That has been the doctrine since the beginning.
This is not in denial here Jim.
What I challenge you on is your personal view that believers have also had to contend with the “real absence” (of bread and wine) as well.
You cannot prove that because it is a relatively recent addition to Church teaching and is really only required if we explain the real presence using Aristotelian Philosophy.
And given that modern science no longer accepts that philosophy I reasonably conclude the faithful are now required to believe a nonsense (that bread is not present) that Christians did not have to assent to in the first 900 years anyways.
You don’t get it, that’s fine.
I am sure others who have always struggled with the “real absence” will hopefully understand they do so with good reason. And it does not mean they do not believe the consecrated bread is not Jesus truly present.
Fathers of the Church have consistently warned that the senses cannot be trusted as to the nature of the Eucharist.
Given that its patent that we cannot see Jesus in the Eucharist do you really think people need to be warned that the senses fail to see Jesus. But it is another thing to say that the senses also fail when they see bread. They do not fail. We see and taste bread. Bread by any modern day common use of the word is there.
The Church has never taught that the bread and wine are intermixed with Christ.
This is irrelevant to the point being made which seems to be lost on you.
Regardless of scientific or philosophical systems, the teaching remains: the whole substance of the bread and wine are changed into the body and blood of Jesus. The Church has never taught consubstantiation.
The truth of that statement is as only as good or helpful as our agreement on the word definitions.
We moderns do not use the word “substance” in the way that Aristotle and the Greek scientists once did sorry. Therefore the above statement, while true, is simply irreleveant and self-contradictory to most moderns who define “substance” as that perceived by the senses (ie effects not causes). Under this definition of “substance” bread certainly remains present.
A rose is still a rose, because the Eucharist is the only instance in history of a substantial change not being accompanied by the corresponding accidental properties.
Clearly you do not understand the truth behind the well known romantic dictum “a rose is a rose” nor that of " if it smells like a rose…" because you just contradicted it

. You need more than empty rhetoric or mantras to give your views weight sorry Jim.
As I say, most people today don’t understand of care for arcane ancient Aristotelian “science”. You may as well be speaking Latin and say that all Catholics must assent to Latin phrases even if they don’t understand them.
You are caught in a time-warp if you think the teaching of Jesus can only be assented to through the mantras of ancient science that were only adopted in C13 and which today have no more currency or practical use than Egyption hieroglyphics.
As I say, to force such “real absence” teachings on the faithful is no longer helpful as it places an additional difficult burden of comprehension that even the disciples did not have to face re the already difficult Eucharistic teaching Jesus gave them originally.
I get it that you don’t.
There is nothing more to say really.
