124. But here let us survey the order in which sins follow each other and increase. First of all Cain sins by presumption and unbelief when, priding himself on the privilege of his birthright, he takes it for granted that he shall be accepted of God on the ground of his own merit. Upon this pride and self-glorification immediately follow envy and hatred of his brother, whom he sees preferred to himself by an unmistakable sign from heaven. Upon this envy and hatred follow hypocrisy and lying. Though he designs to murder his brother, he accosts him in a friendly manner and thereby throws him off his guard. Hypocrisy is followed by murder. Murder is followed by the excusing of his sin. And the last stage is despair, which is the fall from heaven to hell. 125. Although Adam and Eve in paradise did not deny their sin, yet their confession was lukewarm, and the sin was shifted from the one to the other. Adam laid it on Eve, and Eve on the serpent. But Cain went even farther, for he not only did not confess the murder he had committed, but disclaimed responsibility for his brother. And did not this at once prove his mind to be hostile against his brother? Therefore, though Adam and Eve made only a half-hearted confession, they had some claim to pardon, and in consequence were punished with less severity. But Cain, because he resolutely denied his sin, was rejected, and fell into despair. And the same judgment awaits all the sons of Cain, popes, cardinals, and bishops, who, although they plan murder against us day and night, say likewise, "I know not: Am I my brother's keeper?" 126. 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 affair of his. Whereas, if he had said to his father, "Alas, I have slain Abel, my brother. I repent of the deed I have done. Return upon me what punishment thou wilt," there might have been room for a remedy; but as he denied his sin, and, contrary to the will of God, disclaimed responsibility for his brother altogether, there was no place left for mercy or favor.
