Augustine:
Now if those ignorant of the law are in a worse condition than those who know the law, how can this saying of our Lord in the Gospel be true? “That servant who knew his master’s will but did not make ready or act according to his will shall receive a severe beating. But he who did not know and did what deserved a beating shall receive a light beating.” You see that this passage shows clearly a person who knows sins more seriously than one who does not know. Yet we must not on this account take refuge in the darkness of ignorance so as to find there an excuse for our conduct. Not to know is one thing; unwillingness to know is another.1
