ETHICS: Sex, Desire, Art & Porn

The Christian ethic speaks of sin of lust. One interpretation of this has led to terrible sexual repression and self-destruction. Today, fewer Christians know how to define the sin of lust. What's the difference between healthy and wicked desire? What about temptation and addiction?

Christianity has a reputation. Anti-sex, anti-pleasure, anti-art, prudish, conservative and repressed. But not us modern Christians, eh?  We’ve all grown up with Dr Dobson making us wholesome sexual creatures.  So now that we’re past all that old fashioned stuff, let’s start answering some hard questions.  If we are not going to put undies back onto Michaelangelo’s statue of the biblical character King David, just where are we going to draw the line on nudity in art.  What characteristics make nudity and sexuality one person’s art while being another person’s pornography?  Does public art have a different standard from private art collections?  Why?  Can extremely sexually explicit depictions count as art?  Why or why not? 

Furthermore, what is the difference between an appropriate sexual desire and a sinful one?  What is the difference between being tempted by desire and actually sinning though our desires?  And how shall our society handle all these subtleties in a world where sexual addiction is no longer a laughing matter, but a life-destroying tragedy?
