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.
127. Moreover, Moses took special pains in the preparation of this account, that it might serve as a witness against all hypocrites, and as a chronicle containing a graphic description of their character and of the ire to which they are aroused by Satan against God, his Word and his Church. It was not enough for this murderer that he had killed his brother, contrary to the command of God, but he added the further sin that he became filled with indignation and rage when God inquired of him concerning his brother. I say, "when God inquired 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 view of so great a sin, was it not quite gentle to inquire, "Where is Abel thy brother?" And yet, to this word, which contained nothing severe, the hypocrite and murderer is ferocious and proud enough to reply, "I know not." And he is indignant that he should be called to an account concerning the matter at all. For the reply of Cain is the language of one who resists and hates God.
128. But to this sin Cain adds one still worse. Justly under indictment for murder, he presently becomes the accuser of God, and expostulates with him: "Am I my brother's keeper?" He prefaces his reply with no such expression of reverence or honor as is 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 a feeling of reverence toward God or toward his parent. But he answers with pride as if he himself were the Lord, and plainly manifests that he felt indignation at being called to account by him who had the perfect right to do so.
129. This is a true picture of all hypocrites. Living in manifest sins, they grow insolent and proud, aiming all the while to appear righteous. They will not yield even to God himself and his Word when upbraided by them. Nay, they set themselves against God, contend with him, and excuse their sin. Thus David says, that God is judged of men, but that at length he clears and justifies himself, and prevails, Ps 51, 4. Such is the insolence of the hypocrites Moses has here endeavored to paint.
