Commentary on Genesis, Vol. 1: Luther on the Creation

by Martin Luther

In Thuringia there is a small town in the district of Orla, called Neustadt. In this town a harlot had murdered her infant, to which she had secretly given birth, and had thrown it, after the murder, into a neighboring fish-pond. By a singular occurrence a portion of the linen in which she had wrapped the infant brought the horrid deed to light, and the case was brought before the magistrate; and as the simple men of the place knew no better means of investigating the crime in order to discover its author, they called all the young women of the town into the town-hall and closely examined them all, one by one. The judgment concerning all the rest was quite manifest, and it was evident that they were all innocent. But when they came to her who was the real perpetrator of the deed she did not wait for the questions to be put to her, but immediately declared aloud that she was not the guilty person. This declaration at once caused the magistrate to suspect that she really was the author of the deed, because she was more anxious than all the rest to clear herself from any suspicion. Therefore she was seized by the constables and forthwith suffered death.

Indeed examples of the same kind are infinite and occur daily, showing that where persons are most anxious to excuse themselves, they most effectually accuse and betray themselves. So true is that word which we have just before heard that sin does indeed lie asleep and concealed, but it lies "at the door."

Just so in the present case. Cain thinks that he has made an effectual excuse for himself, by saying that he was not his brother's keeper; whereas, by the very mention of his brother's name, he at once confesses that he ought to have been his younger brother's keeper. And then again does he not, by the same admitted confession, that he ought to have been his brother's keeper, accuse himself of being of a hostile mind towards his brother? And does he not moreover strike into the mind of his parents a surmise of the murder committed? For Abel nowhere appears and is not to be found. Just so also Adam excuses himself in paradise, and lays all the blame on Eve. But this excuse of Cain is far more idle and absurd; for while he excuses his sin he doubles it. Whereas on the contrary, the free confession of sin finds mercy and appeases wrath. It is recorded in the history of St. Martin that when he was pronouncing to some notorious sinners the pardon of their sins, he was rebuked by Satan, who asked him why he did so; to whom St. Martin is said to have replied, "Why I would pronounce the pardon even of thy sins, if thou wouldst say from thy heart, I repent that I have sinned against the Son of God, and I pray to God to pardon me for the same." But the devil never does this. For he persists in and defends his sin.

All liars and hypocrites imitate Cain their father in his lie, by either denying their sin, or excusing it. Hence they cannot find pardon of their sins from God. And we see the same in domestic life. By the defense of wrong doing, anger is increased. For whenever the wife, or the children, or the servants have done wrong, and deny or excuse their wrong doing, the father of the family is the more moved to wrath; whereas, on the contrary, plain confession always meets pardon or a lighter punishment. But it is the very nature of hypocrites to excuse and palliate their sin, or to deny it altogether, and under the show of religion to slay the innocent.

But here let us take a view of the manner in which sins follow each other and increase more and more. First of all Cain sins by presumption and unbelief. When priding himself on the privilege of his first birth-right, he takes it for granted that he shall be accepted of God on the ground of his high merit as the eldest son. Upon this pride and this glory of self-righteousness immediately follow the envy and hatred of his brother, whom he sees preferred before himself by a certain sign from heaven. Upon this envy and hatred follow hypocrisy and lying. He talks with his brother in dissembled affection, whom he all the while designs to murder, and whom by his affectionate conversation he throws the more effectually off his guard. Upon this hypocrisy follows murder. Upon this murder follows a lying excuse to cover his awful sin. And the last stage of the whole sin is despair and desperation; and this last step is the fall from heaven to hell!

And although Adam and Eve in paradise did not deny their sin, yet they confessed it quite coldly, and shifted it from the one to the other. Adam laid it on Eve, and Eve laid it on the serpent. But Cain went further than them both, for he not only did not confess the murder he had committed, but declared that he had nothing to do with the care of his brother. And did not this speech at once prove that his mind was in a state of hostility against his brother? Though therefore Adam and Eve confessed their sin with only half their hearts, yet they had some claim to pardon, and they were punished with less severity accordingly. But Cain, because he denied his sin determinately, was rejected, and fell into despair.

And the same judgment awaits all our Cainite popes, cardinals and bishops, who although they plan in their minds plots of murder against us, yet say like Cain their father, "I know not: Am I my brother's keeper?"

There was a common proverb of old, "What is it to the Romans that the Greeks die?" So we think that our dangers and calamities only belong to ourselves. But how does this principle agree with the commandment of God? For his will is, that we should all live together, and be to each other as brethren? Cain therefore by this very saying of his heavily accuses himself when he makes the excuse that the custody of his brother was no matter of his. Whereas if he had said to his father, "Alas, my father, I have slain Abel, my brother. I repent of the deed I have done. Return upon me what punishment thou wilt." Had he thus spoken, there might have been room for a remedy; but as he denied his sin and contrary to the will of God cast off the charge of his brother altogether, there was no place left for mercy or favor.

Moreover Moses has arranged all this narrative thus particularly and remarkably on purpose that it might be a testimony and memorial of all hypocrites, that he might, by his peculiar manner of recording the solemn facts, graphically paint forth what hypocrites really are, and that he might show how awfully they are seized upon by Satan as his instruments, and inflamed by him against God and against his Word and his Church. It was not enough for his murderer that he had killed his brother contrary to the command of God, but he adds to that sin the further sin that, when God inquires of him concerning his brother, he becomes filled with indignation and rage. I say when God inquires of him, because, although it was Adam who spoke these words to his son Cain, yet he spoke them by the authority of God and by the Holy Spirit. In so awful a sin therefore was it not a most kind and gentle manner of expression to inquire, "Where is Abel thy brother?" And yet to this voice, which contained in it nothing severe, the hypocrite and the murderer grows so ferocious and proud that he replies, "I know not: Am I my brother's keeper?" And he is fired with indignation that he should be called to an account concerning the matter at all. For the reply of Cain is the reply of a spirit of resistance and indignation against God.

But to this sin Cain adds a worse sin still. For when he ought to have fallen under this accusation of having committed the murder, he himself at once turns round and accuses God and expostulates with him: "Am I my brother's keeper?" He prefaces his reply with no expression of reverence or honor, though due both to God and to his father. He did not say, "Lord, I know not." He did not say, "My Father, didst thou make me the keeper of my brother?" Such expressions as these would have indicated feeling of reverence towards God or towards his parent. But he answers as being Lord himself and plainly manifests that he felt indignant at being called to account even by him who had the high right even to call him to that account.
