Anti-pelagian Writings by St. Augustine
Chapter 3.--Scriptural Confirmation of the Catholic Doctrine.
This is what we say; this is that about which they object to us that we say |that the law was so given as to be a cause of greater sin.| They do not hear the apostle saying, |For the law worketh wrath; for where no law is, there is no transgression;| and, |The law was added for the sake of transgression until the seed should come to whom the promise was made;| and, |If there had been a law given which could have given life, righteousness should altogether have been by the law; but the Scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.| Hence it is that the Old Testament, from the Mount Sinai, where the law was given, gendereth to bondage, which is Agar. |Now we,| says he, |are not children of the bondmaid but of the freewoman.| Therefore they are not children of the freewoman who have accepted the law of the letter, whereby they can be shown to be not only sinners, but moreover transgressors; but they who have received the Spirit of grace, whereby the law itself, holy and just and good, may be fulfilled. This is what we say: let them attend and not contend; let them seek enlightenment and not bring false accusations.
