First, the doctrine of grace and of the righteousness of faith has been obscured by it, which is the chief part of the Gospel, and ought to stand out as the most prominent in the Church, in order that the merit of Christ may be well known, and faith, which believes that sins are forgiven for Christ's sake be exalted far above works. Wherefore Paul also lays the greatest stress on this article, putting aside the Law and human traditions, in order to show that Christian righteousness is something else than such works, to wit, the faith which believes that sins are freely forgiven for Christ's sake. But this doctrine of Paul has been almost wholly smothered by traditions, which have produced an opinion that, by making distinctions in meats and like services, we must merit grace and righteousness. In treating of repentance, there was no mention made of faith; only those works of satisfaction were set forth; in these the entire repentance seemed to consist.
Secondly, these traditions have obscured the commandments of God, because traditions were placed far above the commandments of God. Christianity was thought to consist wholly in the observance of certain holy-days, rites, fasts, and vestures. These observances had won for themselves the exalted title of being the spiritual life and the perfect life. Meanwhile the commandments of God, according to each one's calling, were without honor namely, that the father brought up his offspring, that the mother bore children, that the prince governed the commonwealth, -- these were accounted works that were worldly and imperfect, and far below those glittering observances. And this error greatly tormented devout consciences, which grieved that they were held in an imperfect state of life, as in marriage, in the office of magistrate; or in other civil ministrations; on the other hand, they admired the monks and such like, and falsely imagined that the observances of such men were more acceptable to God.
Thirdly, traditions brought great danger to consciences; for it was impossible to keep all traditions, and yet men judged these observances to be necessary acts of worship. Gerson writes that many fell into despair, and that some even took their own lives, because they felt that they were not able to satisfy the traditions, and they had all the while not heard any consolation of the righteousness of faith and grace. We see that the summists and theologians gather the traditions, and seek mitigations whereby to ease consciences, and yet they do not sufficiently unfetter, but sometimes entangle, consciences even more. And with the gathering of these traditions, the schools and sermons have been so much occupied that they have had no leisure to touch upon Scripture, and to seek the more profitable doctrine of faith, of the cross, of hope, of the dignity of civil affairs of consolation of sorely tried consciences. Hence Gerson and some other theologians have grievously complained that by these strivings concerning traditions they were prevented from giving attention to a better kind of doctrine. Augustine also forbids that men's consciences should be burdened with such observances, and prudently advises Januarius that he must know that they are to be observed as things indifferent; for such are his words.
Wherefore our teachers must not be looked upon as having taken up this matter rashly or from hatred of the bishops, as some falsely suspect. There was great need to warn the churches of these errors, which had arisen from misunderstanding the traditions. For the Gospel compels us to insist in the churches upon the doctrine of grace, and of the righteousness of faith; which, however, cannot be understood, if men think that they merit grace by observances of their own choice.
Thus, therefore, they have taught that by the observance of human traditions we cannot merit grace or be justified, and hence we must not think such observances necessary acts of worship. They add hereunto testimonies of Scripture. Christ, Matt.15, 3, defends the Apostles who had not observed the usual tradition, which, however, evidently pertains to a matter not unlawful, but indifferent, and to have a certain affinity with the purifications of the Law, and says, 9: In vain do they worship Me with the commandments of men. He, therefore, does not exact an unprofitable service. Shortly after He adds: Not that which goeth into the mouth defileth a man. So also Paul, Rom.14, 17: The kingdom of God is not meat and drink. Col.2, 16: Let no man, therefore, judge you in meat, or in drink, or in respect of an holy-day, or of the Sabbath-day; also: If ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances: Touch not, taste not, handle not! And Peter says, Acts 15, 10: Why tempt ye God to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear? But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they. Here Peter forbids to burden the consciences with many rites, either of Moses or of others. And in 1 Tim.4,1.3 Paul calls the prohibition of meats a doctrine of devils; for it is against the Gospel to institute or to do such works that by them we may merit grace, or as though Christianity could not exist without such service of God.
Here our adversaries object that our teachers are opposed to discipline and mortification of the flesh, as Jovinian. But the contrary may be learned from the writings of our teachers. For they have always taught concerning the cross that it behooves Christians to bear afflictions. This is the true, earnest, and unfeigned mortification, to wit, to be exercised with divers afflictions, and to be crucified with Christ.
Moreover, they teach that every Christian ought to train and subdue himself with bodily restraints, or bodily exercises and labors that neither satiety nor slothfulness tempt him to sin, but not that we may merit grace or make satisfaction for sins by such exercises. And such external discipline ought to be urged at all times, not only on a few and set days. So Christ commands, Luke 21, 34: Take heed lest your hearts be overcharged with surfeiting; also Matt.17, 21: This kind goeth not out but by prayer and fasting. Paul also says, 1 Cor.9, 27: I keep under my body and bring it into subjection. Here he clearly shows that he was keeping under his body, not to merit forgiveness of sins by that discipline, but to have his body in subjection and fitted for spiritual things, and for the discharge of duty according to his calling. Therefore, we do not condemn fasting in itself, but the traditions which prescribe certain days and certain meats, with peril of conscience, as though such works were a necessary service.
Nevertheless, very many traditions are kept on our part, which conduce to good order in the Church, as the Order of Lessons in the Mass and the chief holy-days. But, at the same time, men are warned that such observances do not justify before God, and that in such things it should not be made sin if they be omitted without offense. Such liberty in human rites was not unknown to the Fathers. For in the East they kept Easter at another time than at Rome, and when, on account of this diversity, the Romans accused the Eastern Church of schism, they were admonished by others that such usages need not be alike everywhere. And Irenaeus says: Diversity concerning fasting does not destroy the harmony of faith; as also Pope Gregory intimates in Dist. XII, that such diversity does not violate the unity of the Church. And in the Tripartite History, Book 9, many examples of dissimilar rites are gathered, and the following statement is made: It was not the mind of the Apostles to enact rules concerning holy-days, but to preach godliness and a holy life [, to teach faith and love].
