On the Grace of Christ, and on Original Sin

Then, again, in the work addressed to the holy virgin, of which we have spoken already, there is this passage: “Let us submit ourselves to God, and by doing His will let us merit the divine grace; and let us the more easily, by the help of the Holy Ghost, resist the evil spirit.” Now, in these words of his, it is plain enough that he regards us as assisted by the grace of the Holy Ghost, not because we are unable to resist the tempter without Him by the sheer capacity of our nature, but in order that we may resist more easily. With respect, however, to the quantity and quality, whatever these might be, of this assistance, we may well believe that he made them consist of the additional knowledge which the Spirit reveals to us through teaching, and which we either cannot, or scarcely can, possess by nature. Such are the particulars which I have been able to discover in the book which he addressed to the virgin of Christ, and wherein he seems to confess grace. Of what purport and kind these are, you of course perceive.
