“Yet the theology of the Eucharist itself is a perversion of Scripture”
And you know more than all the Church fathers and 2,000 years of Christian practices, started BY CHRIST HIMSELF!
Wishful thinking. You simply do not know what all the "Church fathers" wrote, (and which are not fathers of the NT church, and in fact it is estimated that what is publicly available is only a small percentage of what they wrote), while this is not necessarily a salvific error by itself.
But in any case, Catholic CFs are not determinative of Truth, who Rome judges them more than they judge her, as she presumes her (non-inspired) words are the supreme authority. But which is the fundamental error of Rome, as a perpetual assuredly infallible magisterium is nowhere promised in Scripture, or necessary for God to provide and preserve Truth.
Instead, it is the wholly inspired-of-God words of Scripture - which all Rome's "infallible" words are not - that are what are determinative of Truth, and which does not teach the endocannibalism of Rome, as has been shown here many times.
And indeed it is a form of endocannibalism.
Alpers and Lindenbaum’s research conclusively demonstrated that kuru [neurological disorder] spread easily and rapidly in the Fore people due to their endocannibalistic funeral practices, in which relatives consumed the bodies of the deceased to return the “life force” of the deceased to the hamlet, a Fore societal subunit. - https://en.wikipedia.org/wiki/Kuru_%28disease%29#Transmission
Moreover, "the custom of eating bread sacramentally as the body of a god was practised by the Aztecs before the discovery and conquest of Mexico by the Spaniards." - http://www.bartleby.com/196/121.html
