Not sure what "Mary Eucharist" is

LOL!!! Isn't that the new Orthodox Christian Rock Group? :O)

Where did you get the idea that the Church's doctrines about the Eucharist developed in the 9-1000's?

The Eucharist was formally adopted in 1215 at the Fourth Lateran Council. We've discussed this before.

+Augustine's speculations on predestination were his own alone.

Nonsense.
"It was not thus that that pious and humble teacher thought—I speak of the most blessed Cyprian—when he said "that we must boast in nothing, since nothing is our own."6 And in order to show this, he appealed to the apostle as a witness, where he said, "For what hast thou that thou hast not received?

--Augustine, A Treatise on Predestination

Cyprian's first Christian writing is "Ad Donatum", a monologue spoken to a friend, sitting under a vine-clad pergola. He tells how, until the grace of God illuminated and strengthened the convert, it had seemed impossible to conquer vice; the decay of Roman society is pictured, the gladiatorial shows, the theatre, the unjust law-courts, the hollowness of political success; the only refuge is the temperate, studious, and prayerful life of the Christian. At the beginning should probably be placed the few words of Donatus to Cyprian which are printed by Hartel as a spurious letter. The style of this pamphlet is affected and reminds us of the bombastic unintelligibilty of Pontius. It is not like Tertullian, brilliant, barbarous, uncouth, but it reflects the preciosity which Apuleius made fashionable in Africa. In his other works Cyprian addresses a Christian audience; his own fervour is allowed full play, his style becomes simpler, though forcible, and sometimes poetical, not to say flowery. Without being classical, it is correct for its date, and the cadences of the sentences are in strict rhythm in all his more careful writings. On the whole his beauty of style has rarely been equalled among the Latin Fathers, and never surpassed except by the matchless energy and wit of St. Jerome.

--NewAdvent on Cyprian

It was through Cyprian that Augustine understood God's grace and man's predestination.

Formal declaration of transubstantiation does not mean that the Eucharist was an invention of the 12th century!!! Must we enter that dead-end again? The Church universally and unanimously taught that Christ was present in the flesh during the Eucharist. Transubstantiation was merely a philosophical term that tried to describe the process of how the elements remained the same, but the essence changed.

"It was not thus that that pious and humble teacher thought—I speak of the most blessed Cyprian—when he said "that we must boast in nothing, since nothing is our own."6 And in order to show this, he appealed to the apostle as a witness, where he said, "For what hast thou that thou hast not received?

That's it? We all believe that! OF COURSE God has given us every good gift! St. Cyprian is not teaching double predestination, but the Catholic belief of God's Providence! Which Catholic is teaching that God actively reprobates men to hell?

I still don't agree that St. Augustine taught double predestination, and the Church didn't teach it either. St. Ambrose CERTAINLY didn't teach it, and I don't see it in your quote of St. Cyprian.
