The Bible as a moral guide

The problem with the Bible as a moral guide is that the Bible is addressed to social situations which change. Just one example, given what we know about the practice of homosexuality in the ancient Roman empire, Paul had every reason to condemn it. See Sarah Ruden's outstanding Paul Among the People for this. But the practice of homosexuality has changed in our day, and so it becomes an interesting question as to whether we an continue to apply Paul's strictures in the present day.

Slavery, in the Old Testament, was the ancient Hebrew welfare system. If you were poor, or in debt, you could become someone's servant. Freeing the slaves would result in people starving as opposed to eating. In Paul's time, just an across the board freeing of slaves would have made their lives worse instead of better. In the very passage where slaves are told to obey their masters, masters are told not to threaten their slaves. That statement should be a major shock. Everyone who reads it should be going What????? What kind of slavery can it possibly be if the slaves cannot be motivated by fear? Obviously we are not talking about anything remotely similar to slavery as it was practiced in the antebellum South. Again, Ruden is good on this. See also this by Warner Wallace.

The main moral contribution of Christianity in the world is not the specific commands that come from it, it is the statement it makes about what people are. People, all of them, are created by God, who has an interest in their eternal salvation, and this interest is demonstrated by the death of Christ on the cross for everyone, black or white, male or female, gay or straight, rich or poor, Jew, Greek or Samaritan. Before this time people, in virtue of who they happened to be, were viewed as human refuse. Obviously we can treat people like crap even though we believe that Christ died for them, but this metaphysic of persons should cause cognitive dissonance if we do so.

The idea that since we can't read morality straight off the Bible, we have to use secular norms, looks like a false dilemma. Modern materialism doesn't just deny biblical commands, it also denies the idea of an objective purpose for human existence. There are things about persons we an learn from seeing them from a Christian perspective, in ways that go over and above the direct commands of the Bible. Consider this famous C. S. Lewis passage:

“There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilization—these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit—immortal horrors or everlasting splendours. This does not mean that we are to be perpetually solemn. We must play. But our merriment must be of that kind (and it is, in fact, the merriest kind) which exists between people who have, from the outset, taken each other seriously—no flippancy, no superiority, no presumption. And our charity must be a real and costly love, with deep feeling for the sins in spite of which we love the sinner—no mere tolerance or indulgence which parodies love as flippancy parodies merriment. Next to the Blessed Sacrament itself, your neighbour is the holiest object presented to your senses. If he is your Christian neighbour he is holy in almost the same way, for in him also Christ vere latitat (truly lies hidden)—the glorifier and the glorified, Glory Himself, is truly hidden.”
