Here is a good reminder from author Andrew Seeley for all of us who work with young people: http://www.catholiceducation.org/articles/arts/al0402.htm
I have to admit, it is hard sometimes to find the beauty in my school building. It's an old place - not old as in "enchanting" and "charming", but old as in "cold", "utilitarian" and "decrepit".
But look a little deeper and walk through our halls: there is awesome student-created art hanging in the halls. Three junior girls laughing so hard they are crying, over something silly: just a shared moment. Our statue of Mary wears a beautiful crown for the month of May. The cafeteria walls remind us, by quotes from saints (diligently painted by our campus youth minister), what our purpose in life is. The staff choir practicing a (surprise!) benediction for the senior Mass and Baccaleaurate.
All of this reminds us that we humans, together with our Creator-God, are the only ones who can create beauty. Tress don't, cats don't, stars don't. Just us. It is our responsibility and our joy. Thanks for the reminder, Mr. Seeley.
