Theology of Clothing
The more I have thought about it, the more am I convinced that the real reason is intimacy, or the lack thereof. Here is the reasoning.
Before the Fall, Adam and Eve first of all each had intimacy with God. Their relationship with God was unmarred. Therefore they had intimacy with each other, and that also was a right relationship.
Then came the Fall. Neither Adam nor Eve then had a right relationship with God; God cursed the relationship between them so that they no longer had intimacy. Because they did not have intimacy, they needed clothes. It follows by contraposition that if you do not need clothes when you are with someone (hopefully your spouse!), you must be intimate with that person.
Now we can see why it is immoral not to wear clothes. Not wearing clothes implies an intimacy. If you don't have that intimacy, then not wearing clothes is really lying. You're saying the intimacy's there when it isn't.
Where am I going with this? A little while ago, I posted a blog entry on female modesty. The present blog entry, to my mind, not only provides the theological reason for my previous comments, but also supports another conclusion: it is equally wrong for men to appear unclothed where there is no intimacy as it is for women. I'm not saying the consequences would necessarily be the same; I understand that men and women are different in how they react to visual stimuli. However, that does not change my line of reasoning here. It is still wrong for men to be naked. So, men: you need to dress modestly also! Furthermore, my little "rule" (please see my previous warnings about legalism) about neck to knees and not too tight seems quite as appropriate for men as it does for women. I realize this goes against the grain of modern culture, which certainly sees nothing wrong with half-naked men going about. I submit to you that 10,000 Frenchmen can still be wrong. Naturally, that does not necessarily make me right. But this is hopefully food for thought. I'd be interested in your ideas.
