Major answered his opponents in his book of 1553 entitled, _A Sermon on the Conversion to God of St. Paul and All God-fearing Men._ In it he most emphatically denied that he had ever taught that good works are necessary in order to _earn_ salvation, and explained more fully "whether, in what way, which, and why good works are nevertheless necessary to salvation." Here he also admits: "This proposition would be dangerous and dark if I had said without any distinction and explanation: Good works are necessary to salvation. For thus one might easily be led to believe that we are saved by good works without faith, or also by the merit of good works, not by faith alone." "We are not just and saved by renewal, and because the fulfilment of the Law is begun in us, as the Interim teaches, but in this life we always remain just and saved by faith _alone._" (Preger 1, 364ff.) Major explains: "When I say: The new obedience or good works which follow faith are necessary to salvation, this is not to be understood in the sense that one must earn salvation by good works, or that they constitute, or could effect or impart the righteousness by which a man may stand before the judgment-seat of God, but that good works are effects and fruits of true faith, which are to follow it [faith] and are wrought by Christ in believers. For whoever believes and is just, he, at the risk of losing his righteousness and salvation, is in duty bound and obliged to begin to obey God as his Father, to do that which is good, and to avoid evil." (370.) Major furthermore modified his statement by explaining: Good works are necessary to salvation, not in order to obtain but to retain, salvation. "In order to retain salvation and not to lose it again," he said, "they are necessary to such an extent that, if you fail to do them, it is a sure indication that your faith is dead and false, a painted faith, an opinion existing only in your imagination." The reason, said Major (Menius, too, later on expressed his agreement in this point with Major), why he had urged his proposition concerning the necessity of good works to salvation, was the fact that the greater number also of those who claim to be good evangelical Christians "imagine that they believe, and imagine and fabricate a faith which may exist without good works, though this is just as impossible as that the sun should not emit brightness and splendor." (Tschackert 515; Frank 2, 162. 373.)
