Anti-pelagian Writings by St. Augustine
Chapter 9 [V.]--He Replies to the Calumnies of the Pelagians.
And now we must look to those things which they objected to us in their letters, and briefly mentioned. And to these this is my answer. We do not say that by the sin of Adam free will perished out of the nature of men; but that it avails for sinning in men subjected to the devil; while it is not of avail for good and pious living, unless the will itself of man should be made free by God's grace, and assisted to every good movement of action, of speech, of thought. We say that no one but the Lord God is the maker of those who are born, and that marriage was ordained not by the devil, but by God Himself; yet that all are born under sin on account of the fault of propagation, and that, therefore, all are under the devil until they are born again in Christ. Nor are we maintaining fate under the name of grace, because we say that the grace of God is preceded by no merits of man. If, however, it is agreeable to any to call the will of the Almighty God by the name of fate, while we indeed shun profane novelties of words, we have no use for contending about words.
