Thanks to the commenters who contributed to the previous post on the subject of modesty, or the growing lack of it, in the church. Some of you anticipated my thinking a bit.
Discussions on this subject encounter a lot of ire these days, especially from the younger set. And as noted earlier, you will also encounter objections from those who insist any attempt to uphold a certain standard crosses into the line of legalism.
It goes without saying that Scripture ought to be our guide in these matters. Aside from Scripture, I can't help thinking about what a Supreme Court justice was supposed to have said once on defining obscenity. "I'll know it when I see it." That is a bit loose for me, especially when we have clear, overwhelming guidance from God's Word that a Christian's standards are supposed to be higher than the unregenerate world's standards.
But what about the fact that styles, fashions and tastes change over time? That might be true, but the general sense of God's Word never changes. I am not advocating that people adopt the styles in the photos I posted of 19th century swimming attire (or hoop skirts and corsets). However, I do believe that some free-spirited believers have come to be comfortable with the idea of thong bikinis at the beach and Sharon Stone moments in the church. (I've seen it come close, I kid you not!)
I am going to point to some Scriptures, beginning with the Old Testament. While we as believers are not under the Law of Moses, and the Law is not salvific, the Old Testament is still part of God's Word. The things that God considered evil are still evil. The Old Testament is still instructive to us in discerning principles. It is still instructive to us in learning about God's attitudes toward certain things.
Even in the beginning with the fall of man, you can see that there is a sense of shame with nakedness. As soon as they ate of the tree, Adam and Eve were aware that they were naked and covered themselves. Before the fall, there was no such shame. If need be, we can discuss the reasons for this at another time. For the purposes of this discussion, it's important to note the change that took place after the fall.
Genesis 9 contains the account of Noah's drunkenness, and his sons' respective attitudes toward the nakedness of their father. Leviticus 18 has numerous strictures about uncovering the nakedness of various individuals. These typically have sexual morality in view, but there is also the general principle of modesty. First Samuel and Isaiah reference the shame of nakedness. There are many more.
In the New Testament, Revelation 3:18 contains words by Jesus aimed at the church of Laodicea, again using the word picture of shame associated with nakedness. Again, there are numerous examples from the NT I could cite showing a general attitude toward nakedness. Nakedness is often connected with shame. It is obvious to me that outside of the marriage bed of a husband and wife, exposing oneself -- especially in public -- is not considered to be a good thing.
There is another issue beyond nakedness or scant clothing in and of itself. It is the matter of Christian love. The Old and New Testaments make it clear that we ought not to be a bad example or an allurement to those around us. We are not supposed to cause others to stumble. We are supposed to flee youthful lusts. And even if you don't have a problem with lust, you might well cause a problem for someone else who might.
Many in our youth culture -- thanks to the godless education and man-centered, self-esteeming philosophies they are force-fed -- have the attitude that self-expression is their god, even if they won't put it that way. "I have the right to be me." "I am not ashamed of my body." That is not a godly attitude. That is an attitude that comes right off of the altar of self-centered rebellion.
I am not out to impose some sort of dress code. But I really think that Christians -- old and young -- ought to really consider their behavior in light of what God's Word says. Way too many people who call themselves Christians blow off Scripture with too much aplomb. A Christian boy walking down the street or in church with his pants pulled down so far that his pubic hair is exposed, or a Christian girl walking around with three-quarters of her breasts showing (with nipple outlines) is inexcusable.
But to some people in the church today, even that is not obvious. In some circles, it seems that defending the indefensible has become a new art form.
