It is incorrect to say that the Church rejected most of St. Augustine's teachings when it was only the Eastern part of the Church that did so. His teaching, with exceptions, has always been held in the West. The Eastern bishops do not speak for the entire Church.
I was referring to the Church in the East ("When the East finally learned of his work in the 14th century, the Church..."). It is clear that the Church in this case is limited only to the Church in the East, as the Church was no longer undivided at that time.
If there was any ambiguity, I never wanted to imply that the Church in the West followed in the East's foot steps on this matter.
