‘Admonishments of this kind [the Ten Commandments] are found in virtually every culture throughout recorded history. There is nothing especially compelling about their presentation in the Bible. There are obvious biological reasons why people tend to treat their parents well, and to think badly of murderers, adulterers, thieves, and liars. It is a scientific fact that moral emotions—like a sense of fair play or an abhorrence of cruelty—precede any exposure to scripture. Indeed, studies of primate behavior reveal that these emotions (in some form) precede humanity itself. All of our primate cousins are partial to their own kin and generally intolerant of murder and theft.
They tend not to like deception or sexual betrayal much, either. Chimpanzees, especially, display many of the complex social concerns that you would expect to see in our closest relatives in the natural world. It seems rather unlikely, therefore, that the average American will receive necessary moral instruction by seeing these precepts chiseled in marble whenever he enters a courthouse. And what are we to make of the fact that, in bringing his treatise to a close, the creator of our universe could think of no human concerns more pressing and durable than the coveting of servants and livestock?
If we are going to take the God of the Bible seriously, we should admit that He never gives us the freedom to follow the commandments we like and neglect the rest. Nor does He tell us that we can relax the penalties He has imposed for breaking them.
If you think that it would be impossible to improve upon the Ten Commandments as a statement of morality, you really owe it to yourself to read some other scriptures. Once again, we need look no further than the Jains: Mahavira, the Jain patriarch, surpassed the morality of the Bible with a single sentence: “Do not injure, abuse, oppress, enslave, insult, torment, torture, or kill any creature or living being.” Imagine how different our world might be if the Bible contained this as its central precept. Christians have abused, oppressed, enslaved, insulted, tormented, tortured, and killed people in the name of God for centuries, on the basis of a theologically defensible reading of the Bible. It is impossible to behave this way by adhering to the principles of Jainism. How, then, can you argue that the Bible provides the clearest statement of morality the world has ever seen?’
