Outline of Satan
Satan, also known as the Devil, is an entity in the Abrahamic religions that seduces humans into sin or falsehood. In Christianity and Islam, he is usually seen as either a fallen angel or a jinn, who used to possess great piety and beauty, but rebelled against God, who nevertheless allows him temporary power over the fallen world and a host of demons. In Judaism, Satan is typically regarded as a metaphor for the yetzer hara, or “evil inclination“, or as an agent subservient to God.
A figure known as “the satan” first appears in the Tanakh as a heavenly prosecutor, a member of the sons of God subordinate to Yahweh, who prosecutes the nation of Judah in the heavenly court and tests the loyalty of Yahweh’s followers by forcing them to suffer. During the intertestamental period, possibly due to influence from the Zoroastrian figure of Angra Mainyu, the satan developed into a malevolent entity with abhorrent qualities in dualistic opposition to God. In the apocryphal Book of Jubilees, Yahweh grants the satan (referred to as Mastema) authority over a group of fallen angels, or their offspring, to tempt humans to sin and punish them. In the Synoptic Gospels, Satan tempts Jesus in the desert and is identified as the cause of illness and temptation. In the Book of Revelation, Satan appears as a Great Red Dragon, who is defeated by Michael the Archangel and cast down from Heaven. He is later bound for one thousand years, but is briefly set free before being ultimately defeated and cast into the Lake of Fire.
