Beauty, vanity, immodesty and lust

As you can see from the title, this sequence flows downward.  It all begins with how one defines beauty.  Of course, you should know by now, I insist that one must look to the church for such a definition.  If one starts from any other foundation, the whole thing will eventually get ugly (sinful).
We are all far too self centered and prone to sin to trust ourselves with defining reality.
To tie this in with a former post, beauty cannot be defined by old covenant standards.  Beauty is not about the outside, but the heart.  When one builds his or her life upon a foundation of love for God and neighbor, he or she will be beautiful.  The person who pours time and money into externals (ie, old covenant thinking) will end up with nothing.
