The encyclical letter Laudato Si is available here on the Vatican website. Pope Francis reviews “A Universal Communion in section V of Chapter Two.
89. The created things of this world are not free of ownership: “For they are yours, O Lord, who love the living” (Wis 11:26). This is the basis of our conviction that, as part of the universe, called into being by one Father, all of us are linked by unseen bonds and together form a kind of universal family, a sublime communion which fills us with a sacred, affectionate and humble respect. Here I would reiterate that “God has joined us so closely to the world around us that we can feel the desertification of the soil almost as a physical ailment, and the extinction of a species as a painful disfigurement”.[Evangelii Gaudium 215]
This is a natural consequence of what we’ve read the past few days, that as part of God’s Creation, we human beings are connected to the universe. We are not just component parts. Not all of us have the sensitivity and vision to recognize the interacting relationships of which we are a part.
