50. We need the Holy Spirit to understand the Holy Scriptures. For we know that the same Spirit shall exist to the end of the world who existed before all things. We glory in possessing this Spirit through the grace of God, and, through him, we have faith, a moderate knowledge of Scripture and an understanding of the other things necessary to godliness. Hence we do not invent a new interpretation; we are guided not only by an analogy of Holy Scripture but also by faith.
51. Through the Holy Scriptures in its entirety, the verb judge, dun, signifies almost invariably a public office in the Church, or the office of the ministry, through which we are corrected, reproved, instructed and enabled to distinguish the evil from the good, etc. Thus, Psalm 110, 6: Jadin bagojim, "He will judge among the nations;" which means: He will preach among the nations. The word found in this passage is evidently the same. And in the New Testament this phrase, originally Hebrew, is very much in vogue, especially in Paul's writings, who uses the Hebrew idiom more than the others.
52. I understand this passage therefore as words spoken by Lamech or Noah as a new message to the whole world. For it was a public message proclaimed at some public assembly. When Methuselah, Lamech and Noah saw that the world was hastening straight to destruction by its sins, they resorted to this proclamation: My Spirit shall no longer preach among men. That means: we teach in vain, we admonish in vain; the world has no desire to be better.
53. It is as if one in the present perverse times should say: We teach and make ample effort to summon the world back to sobriety and godliness, but we are derided, persecuted, killed, and all men, in the end, rush to destruction with blind eyes and deaf ears; therefore we are constrained to desist. These are the words of a soul planning appropriate action and full of anxiety, because it is clear that the human race, at the height of its peril, cannot be healed.
54. This exposition conforms to faith and Holy Scriptures. When the Word is revealed from heaven, we see that some are converted, who are freed from damnation. The remaining multitude despises it and securely indulges in avarice, lust and other vices, as Jeremiah says (ch 51, 9): "We should have healed Babylon, but she is not healed: forsake her, and let us go everyone into his own country."
The more diligently Moses and Aaron importuned and instructed, the more obstinate Pharaoh became. The Jews were not made better by even the preaching of Christ and the apostles. The same befalls us who teach in our day. What, in consequence, are we to do? Deplore the blindness and obstinacy of men we may, correct it we cannot. Who would rejoice in the eternal damnation of the popes and their followers? Who would not prefer that they should embrace the Word and recover their senses?
