the Fathers. For Augustine, in many volumes, defends grace and the righteousness of faith, over against the merits of works. And Ambrose, in his De Vocatione Gentium, and elsewhere, teaches to like effect. For in his De Vocatione Gentium he says as follows: Redemption by the blood of Christ would become of little value, neither would the preeminence of man's works be superseded by the mercy of God, if justification, which is wrought through grace, were due to the merits going before, so as to be, not the free gift of a donor, but the reward due to the laborer.
But, although this doctrine is despised by the inexperienced, nevertheless God-fearing and anxious consciences find by experience that it brings the greatest consolation, because consciences cannot be set at rest through any works, but only by faith, when they take the sure ground that for Christ's sake they have a reconciled God. As Paul teaches Rom. 5, 1: Being justified by faith, we have peace with God. This whole doctrine is to be referred to that conflict of the terrified conscience, neither can it be understood apart from that conflict. Therefore inexperienced and profane men judge ill concerning this matter, who dream that Christian righteousness is nothing but civil and philosophical righteousness.
Heretofore consciences were plagued with the doctrine of works, they did not hear the consolation from the Gospel. Some persons were driven by conscience into the desert, into monasteries hoping there to merit grace by a monastic life. Some also devised other works whereby to merit grace and make satisfaction for sins. Hence there was very great need to treat of, and renew, this doctrine of faith in Christ, to the end that anxious consciences should not be without consolation but that they might know that grace and forgiveness of sins and justification are apprehended by faith in Christ.
Men are also admonished that here the term "faith" does not signify merely the knowledge of the history, such as is in the ungodly and in the devil, but signifies a faith which believes, not merely the history, but also the effect of the history -- namely, this Article: the forgiveness of sins, to wit, that we have grace, righteousness, and forgiveness of sins through Christ.
Now he that knows that he has a Father gracious to him through Christ, truly knows God; he knows also that God cares for him, and calls upon God; in a word, he is not without God, as the heathen. For devils and the ungodly are not able to believe this Article: the forgiveness of sins. Hence, they hate God as an enemy, call not upon Him, and expect no good from Him. Augustine also admonishes his readers concerning the word "faith," and teaches that the term "faith" is accepted in the Scriptures not for knowledge such as is in the ungodly but for confidence which consoles and encourages the terrified mind.
Furthermore, it is taught on our part that it is necessary to do good works, not that we should trust to merit grace by them, but because it is the will of God. It is only by faith that forgiveness of sins is apprehended, and that, for nothing. And because through faith the Holy Ghost is received, hearts are renewed and endowed with new affections, so as to be able to bring forth good works. For Ambrose says: Faith is the mother of a good will and right doing. For man's powers without the Holy Ghost are full of ungodly affections, and are too weak to do works which are good in God's sight. Besides, they are in the power of the devil who impels men to divers sins, to ungodly opinions, to open crimes. This we may see in the philosophers, who, although they endeavored to live an honest life could not succeed, but were defiled with many open crimes. Such is the feebleness of man when he is without faith and without the Holy Ghost, and governs himself only by human strength.
Hence it may be readily seen that this doctrine is not to be charged with prohibiting good works, but rather the more to be commended, because it shows how we are enabled to do good works. For without faith human nature can in no wise do the works of the First or of the Second Commandment. Without faith it does not call upon God, nor expect anything from God, nor bear the cross, but seeks, and trusts in, man's help. And thus, when there is no faith and trust in God all manner of lusts and human devices rule in the heart. Wherefore Christ said, John 16,6: Without Me ye can do nothing; and the Church sings: Lacking Thy divine favor, There is nothing found in man, Naught in him is harmless.
