“Canticle of the Creatures Most High, all powerful, good Lord, Yours are the praises, the glory, the honor, and all blessing. To You alone, Most High, do they belong, and no man is worthy to mention Your name. Be praised, my Lord, through all your creatures, especially through my lord Brother Sun, who brings the day; and you give light through him. And he is beautiful and radiant in all his splendor! Of you, Most High, he bears the likeness. Praise be You, my Lord, through Sister Moon and the stars, in heaven you formed them clear and precious and beautiful. Praised be You, my Lord, through Brother Wind, and through the air, cloudy and serene, and every kind of weather through which You give sustenance to Your creatures. Praised be You, my Lord, through Sister Water, which is very useful and humble and precious and chaste. Praised be You, my Lord, through Brother Fire, through whom you light the night and he is beautiful and playful and robust and strong. Praised be You, my Lord, through Sister Mother Earth, who sustains us and governs us and who produces varied fruits with colored flowers and herbs. Praised be You, my Lord, through those who give pardon for Your love, and bear infirmity and tribulation. Blessed are those who endure in peace for by You, Most High, they shall be crowned. Praised be You, my Lord, through our Sister Bodily Death, from whom no living man can escape. Woe to those who die in mortal sin. Blessed are those whom death will find in Your most holy will, for the second death shall do them no harm. Praise and bless my Lord, and give Him thanks and serve Him with great humility”
Francis of Assisi was a Catholic deacon and the founder of the Order of Friars Minor, more commonly known as the Franciscans.
Francis heard a sermon that changed his life. The sermon was about Matthew 10:9, in which Christ tells his followers that they should go forth and proclaim that the Kingdom of Heaven was upon them, that they should take no money with them, nor even a walking stick or shoes for the road. Francis was inspired to devote himself to a life of poverty.
Francis's attitude towards the natural world, while poetically expressed, was conventionally Christian. He believed that the world was created good and beautiful by God but suffers a need for redemption because of the primordial sin of man. He preached to man and beast the universal ability and duty of all creatures to praise God (a common theme in the Psalms) and the duty of men to protect and enjoy nature as both the stewards of God's creation and as creatures ourselves.
