Against Two Letters of the Pelagians

But those enemies of grace never endeavour to lay more secret snares for more vehement opposition to that same grace than when they praise the law, which, without doubt, is worthy to be praised. Because, by their different modes of speaking, and by variety of words in all their arguments, they wish the law to be understood as “grace”— that, to wit, we may have from the Lord God the help of knowledge, whereby we may know those things which have to be done—not the inspiration of love, that, when known, we may do them with a holy love, which is properly grace.

For the knowledge of the law without love puffs up, does not edify, according to the same apostle, who most openly says, “Knowledge puffs up, but love edifies.” Which saying is like to that in which it is said, “The letter kills, the spirit makes alive.” For “Knowledge puffs up,” corresponds to “The letter kills:” and, “Love edifies,” to “The spirit makes alive;” because “the love of God is shed abroad in our hearts by the Holy Spirit who is given unto us.” Therefore the knowledge of the law makes a proud transgressor; but, by the gift of charity, he delights to be a doer of the law.

We do not then make void the law through faith, but we establish the law, which by terrifying leads to faith. Thus certainly the law works wrath, that the mercy of God may bestow grace on the sinner, frightened and turned to the fulfilment of the righteousness of the law through Jesus Christ our Lord, who is that wisdom of God of which it is written, “She carries law and mercy on her tongue,” — law whereby she frightens, mercy by which she may help—law by His servant, mercy by Himself—the law, as it were, in the staff which Elisha sent to raise up the son of the widow, and it failed to raise him up, “For if a law had been given which could have given life, righteousness would altogether have been by the law,” but mercy, as it were, in Elisha himself, who, wearing the figure of Christ, by giving life to the dead was joined in the signification of the great sacrament, as it were, of the New Testament.
