Anti-pelagian Writings by St. Augustine
Chapter 3 [II.]--Even the Beginning of Faith is of God's Gift.
Therefore I ought first to show that the faith by which we are Christians is the gift of God, if I can do that more thoroughly than I have already done in so many and so large volumes. But I see that I must now reply to those who say that the divine testimonies which I have adduced concerning this matter are of avail for this purpose, to assure us that we have faith itself of ourselves, but that its increase is of God; as if faith were not given to us by Him, but were only increased in us by Him, on the ground of the merit of its having begun from us. Thus there is here no departure from that opinion which Pelagius himself was constrained to condemn in the judgment of the bishops of Palestine, as is testified in the same Proceedings, |That the grace of God is given according to our merits,| if it is not of God's grace that we begin to believe, but rather that on account of this beginning an addition is made to us of a more full and perfect belief; and so we first give the beginning of our faith to God, that His supplement may also be given to us again, and whatever else we faithfully ask.
