"Behind the disobedient choice of our first parents lurks a seductive voice, opposed to God, which makes them fall into death out of envy. Scripture and the Church's Tradition see in this being a fallen angel, called 'Satan' or the 'devil.' The Church teaches that Satan was at first a good angel, made by God: 'The devil and the other demons were indeed created naturally good by God, but they became evil by their own doing'" (CCC 391).
