See below for B.B. Warfield's summary of the Pelagian controversy
At this point we have touched the central and formative principle of Pelagianism. It lies in the assumption of the plenary ability of man; his ability to do all that righteousness can demand — to work out not only his own salvation, but also his own perfection. This is the core of the whole theory; and all the other postulates not only depend upon it, but arise out of it. Both chronologically and logically this is the root of the system.
The theology which Augustine opposed, in his anti-Pelagian writings, to the errors of Pelagianism, is, shortly, the theology of grace. Its roots were planted deeply in his own experience, and in the teachings of Scripture, especially of that apostle whom he delights to call 'the great preacher of grace,' and to follow whom, in his measure, was his greatest desire. The grace of God in Jesus Christ, conveyed to us by the Holy Spirit and evidenced by the love that He sheds abroad in our hearts, is the centre around which this whole side of His system revolves, and the germ out of which it grows. He was the more able to make it thus central because of the harmony of this view of salvation with the general principle of his whole theology, which was theocentric and revolved around his conception of God as the immanent and vital spirit in whom all things live and move and have their being. In like manner, God is the absolute good, and all good is either Himself or from Him; and only as God makes us good, are we able to do anything good.
