To find the story of the fall of Satan, we must go to sources other than the Bible. There was a great deal of literature produced roughly between 200 BC and 150 AD, including the Apocrypha and the Pseudepigrapha. Some of these are apocalyptic -- they prophesy cataclysmic events and the end of the world. In this literature one can see the development of the idea of an evil spirit, but even in the apocalyptic literature the Devil does not become entirely evil in his origin and essence. Many of the books from this period reflect the misery of the Jewish people under the oppression of Syria and Rome. Their writings deal with visions of the end of the world, the world being in the power of the Devil, and the Messiah conquering the Devil and bringing a new era of justice. The Book of Enoch is seen by many as one of the earliest and most important accounts of the mishaps of the Heavenly Court (of angels). It also describes the rebellion of the angel Satanail, and his being hurled from heaven (2 Enoch, ch. 29, long MSS only). Some scholars take this to mean that the amalgamation of Satan and Lucifer goes back to the first century. A redating of 2 Enoch, however, puts it later than the third century, perhaps even in the seventh. For this reason others suggest that Origen (Exhort. 18) was probably the inventor of the identification of Lucifer with Satan (Satan: The Early Christian Tradition, Jeffrey Burton Russell, Cornell University Press, Ithaca, 1991, p. 130 & fn). The Life of Adam and Eve (Vita), a Jewish scripture that scholars date between 200 BC and 200 AD, relates that Satan tells Adam and Eve that his fall from heaven is the result of his refusal to worship Adam, the image of God. A similar account is also found in the Koran (S 2:34). These legends reflect a theme close to the primordial "pride" that led to the so-called fall of Satan.
Since the Old Testament does not connect pride or the Fall with Satan, the Devil, or the Adversary, the only scriptural "support" for this notion is the misinterpretation of the fall of Lucifer (the king of Babylon), and certain passages in the New Testament. But the New Testament does not give any clear information on the fall of Satan through pride either. One place where Lucifer is connected with pride is in Milton's Paradise Lost. He "applied the name to the demon of sinful pride" ("Lucifer," A Dictionary of Angels, Gustav Davidson, The Free Press, New York, 1967).
