Apparently, Doug Wilson has gotten himself into (yet another) kerfuffle by making the horrible observation that Christian women are prettier, and then defending that wild claim. Because, of course, it must be a sin to notice that a woman (or man) is attractive, which is why Christ explicitly condemns the Holy Spirit for noticing that Rachel and David (and a bunch of others) were attractive.
Um, wait, not in my Bible. No, our Lord does not do this. So wait a minute on this one; if God Himself can notice that a person is attractive without sinning (and of course that's the case), exactly why would we say that a person cannot do the same? It is as if we've forgotten the difference between a smile and a leer.
Now there may be great reason not to verbalize the fact that many of our sisters in church are very pretty in some cases--our current culture being about 100 of those reasons--but if we outright say there's something wrong with noticing, we're really coming close to saying something about our Counselor that we really ought not say. And the Bible does say something about that.
