By the 3rd century, there is evidence that some early Christians accepted this Jewish Enochic pseudepigraphy and the application of the angelic descent myth to the "sons of God" passage in Genesis 6:1-4,[9] Its presence not only in the East but also in the Latin-speaking West is attested by the polemic of Augustine of Hippo (354–430) against the motif of giants born of the union between fallen angels and human women.[10] Rabbinic Judaism and Christian authorities rejected the tradition.[11] Those who adopted the tradition viewed the "sons of God" as fallen angels who married human women and by unnatural union begot the Nephilim.[

A Jewish myth of angels coming down to earth rather than being cast down, referred to as the myth of angelic descent,[15] is found chiefly in the Jewish pseudepigraphic Book of Enoch, 6-9 and the Qumran Book of Giants and perhaps in Genesis 6:1-4.[16] The angels in question were Watchers[17] who were inveigled by the beauty of human women,[16] had intercourse with them and corrupted mankind.[18] They were the prime instigators of the sinfulness that led to the Great Deluge.[19] This myth was adopted by early Christianity, but abandoned by Rabbinic Judaism and later Christianity.[17] During the period immediately before the rise of Christianity, the intercourse between these Watchers and human women was often seen as the first fall of the angels.[

The Hebrew Bible does not say that Satan is an angel, nor that he is fallen: it uses the corresponding Hebrew word, which means "adversary", of human opponents or some evil influence, but in three places it personifies Satan as a character, always inferior to God's power: it portrays him as an accuser (Zechariah 3:1-2), a seducer (1 Chronicles 21:1) or a heavenly persecutor (Job 2:1.[31]

Origen and other Christian writers linked the fallen morning star of Isaiah 14:12 to Jesus' statement in Luke 10:18, "I saw Satan fall like lightning from heaven" and to the mention of a fall of Satan in Revelation 12:8-9

The concept of fallen angels is first found in Judaism among texts of the Second Temple era, being applied in particular to Azazel[40] and Satan.[31] However, from the Middle Ages certain Jewish scholars, both rationalist and traditionalist, rejected belief in rebel or fallen angels, since they considered evil as simply the absence of good or at least as not absolute.[41] [edit]Christianity
