From my post immediately following the one you quoted:
In the course of the
dogma’s history there arose in general three great
Eucharistic controversies … The first occasion for an official procedure on the part of the
Church was offered when
Berengarius of Tours, influenced by the writings of
Scotus Eriugena (d. about 884), the first opponent of the Real Presence, rejected both the latter
truth and that of
Transubstantiation. He repaired, however, the
public scandal he had given by a sincere retractation made in the presence of
Pope Gregory VII at a
synod held in
Rome in 1079, and died reconciled to the
Church.
I suspect you date the Great Schism to 1054. From
this link:
In other words, well
after the dogma of Transubstantiation “sprang up” (as you put it),
From the same post immediately following the one you quoted (emphasis mine):
As for the cogency of the argument from
tradition, this historical fact is of decided significance, namely, that
the dogma of the Real Presence remained, properly speaking, unmolested down to the time of the
heretic Berengarius of Tours (d. 1088), and so could claim even at that time the uninterrupted possession of ten centuries.
Jesus tells us he is “the Way, the Truth, and the Life” – not “a Way, a Truth, and a Life.” Truth doesn’t change (though, like a small acorn which grows into a mighty oak, our understanding of
Truth does grow and mature). So, what was Truth at the time of Jesus (and, for that matter, what was Truth in the late 15th century) is just as much Truth today. But as Wikipedia summarizes, “Luther dogmatically asserted what he considered firmly established biblical doctrines like the divine motherhood of Mary while adhering to pious opinions of her perpetual virginity and immaculate conception along with the caveat that all doctrine and piety should exalt and not diminish the person and work of Jesus Christ” (remember that this was some three-hundred years before the formal dogmatization of the Immaculate Conception by Pope Pius IX in 1854!), Lutheran “truth” seems to have evolved away from this Truth.
