Augustinian predestination is not the doctrine of the Church but only the opinion of a distinguished Catholic theologian. --as quoted in D. MacCulloch, Christianity: The First Three Thousand Years, p. 308. MacCulloch cites G. Bonner, Saint Augustine of Hippo: Life and Controversies. 2d edition. (Norwich, 1963), pp. 394-95.
To see numerous examples of the early church's commitment to the doctrine of human free will as opposed to predestination, take a look at this page at the website of the Austin Graduate School of Theology.
