[T]he one and true God, in order to bind the parts of the universe in a firm alliance and to keep charity alive, ordered them in such a way that one thing needed the help of another, and one made good the deficiency of another, every single one being as it were a member of every other one. All things if separated from one another are thus only half complete, but are made perfect when allied to others, since all things are held together by mutual support. (ML: 125)
