339 Each creature possesses its own particular goodness and perfection. For each one of the works of the "six days" it is said: "And God saw that it was good." "By the very nature of creation, material being is endowed with its own stability, truth and excellence, its own order and laws." Each of the various creatures, willed in its own being, reflects in its own way a ray of God's infinite wisdom and goodness. Man must therefore respect the particular goodness of every creature, to avoid any disordered use of things which would be in contempt of the Creator and would bring disastrous consequences for human beings and their environment.
