A little boy attended a church that had beautiful stained-glass windows. The stained-glass windows, he learned, contained pictures of Saint Matthew, Saint Mark, Saint Luke, Saint John, Saint Paul, etc.
One day he was asked, “Who is a saint?”
He replied, “A saint is a person the light shines through.”
