Saint Francis invited all of creation—animals, plants, natural forces, even Brother Sun and Sister Moon—to give honor and praise to the Lord. It is my hope that the inspiration of Saint Francis will help us to keep ever alive a sense of fraternity with all those good and beautiful things which Almighty God has created. And may he remind us of our serious obligation to respect and watch over them with care.
