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.
