Anti-pelagian Writings by St. Augustine
(42.) God's Promises Conditional. Saints of the Old Testament Were Saved by the Grace of Christ.
He, however, thought he had discovered a great support for his cause in the prophet Isaiah; because by him God said: |If ye be willing, and hearken unto me, ye shall eat the good of the land; but if ye be not willing, and hearken not to me, the sword shall devour you: for the mouth of the Lord hath spoken this.| As if the entire law were not full of conditions of this sort; or as if its commandments had been given to proud men for any other reason than that |the law was added because of transgression, until the seed should come to whom the promise was made.| |It entered, therefore, that the offence might abound; but where sin abounded, grace did much more abound.| In other words, That man might receive commandments, trusting as he did in his own resources, and that, failing in these and becoming a transgressor, he might ask for a deliverer and a saviour; and that the fear of the law might humble him, and bring him, as a schoolmaster, to faith and grace. Thus |their weaknesses being multiplied, they hastened after;| and in order to heal them, Christ in due season came. In His grace even righteous men of old believed, and by the same grace were they holpen; so that with joy did they receive a foreknowledge of Him, and some of them even foretold His coming, -- whether they were found among the people of Israel themselves, as Moses, and Joshua the son of Nun, and Samuel, and David, and other such; or outside that people, as Job; or previous to that people, as Abraham, and Noah, and all others who are either mentioned or not in Holy Scripture. |For there is but one God, and one Mediator between God and man, the man Christ Jesus,| without whose grace nobody is delivered from condemnation, whether he has derived that condemnation from him in whom all men sinned, or has afterwards aggravated it by his own iniquities.
