Satan

Overview

Satan, also known as the Devil, is an entity in Abrahamic religions who entices humans into sin or falsehood. In Judaism, Satan is seen as an agent subservient to God, typically regarded as a metaphor for the yetzer hara, or 'evil inclination'. In Christianity and Islam, he is usually seen as a fallen angel or jinn who has rebelled against God, who nevertheless allows him temporary power over the fallen world and a host of demons.

A figure known as ha-satan ("the satan") first appears in the Hebrew Bible as a heavenly prosecutor, subordinate to Yahweh (God); he prosecutes the nation of Judah in the heavenly court and tests the loyalty of Yahweh's followers. 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.

Although the Book of Genesis does not name him specifically, Christians often identify the serpent in the Garden of Eden as Satan. 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.

In the Quran, Iblis (Shaitan), the leader of the devils (shayāṭīn), is made of fire and was cast out of Heaven because he refused to bow before the newly created Adam. He incites humans to sin by infecting their minds with waswās ('evil suggestions').

In the Middle Ages, Satan played a minimal role in Christian theology and was used as a comic relief figure in mystery plays. During the early modern period, Satan's significance greatly increased as beliefs such as demonic possession and witchcraft became more prevalent. During the Age of Enlightenment, belief in the existence of Satan was harshly criticized by thinkers such as Voltaire. Nonetheless, belief in Satan has persisted, particularly in the Americas.

Although Satan is generally viewed as evil, some groups have very different beliefs. In theistic Satanism, Satan is considered a deity who is either worshipped or revered. In LaVeyan Satanism, Satan is a symbol of virtuous characteristics and liberty. Satan's appearance is never described in the Bible, but, since the ninth century, he has often been shown in Christian art with horns, cloven hooves, unusually hairy legs, and a tail, often naked and holding a pitchfork. These are an amalgam of traits derived from various pagan deities, including Pan, Poseidon, and Bes. Satan appears frequently in Christian literature, most notably in Dante Alighieri's Inferno, all variants of the classic Faust story, John Milton's Paradise Lost and Paradise Regained, and the poems of William Blake.

Passages from public-domain books where Satan is discussed.

God does not join them together in one and the same punishment, as he might righteously have done. He makes the widest distinction between them. For although he is angry with man also, who obeyed the enemy of God, disregarding God himself, yet the divine indignation against Satan is by far the greater. Satan God plainly convicts and condemns in the sight of Adam and Eve, so that Adam and Eve, from this very…

It was so decidedly a real serpent, that all its species, which had before walked on their feet, were condemned to crawl on their bellies. No serpent, no animal of any kind, is called Satan, or Beelzebub, or devil, in the Pentateuch. There is not so much as an allusion to Satan. The Dutch destroyer of Satan does, indeed, admit the existence of angels; but at the same time he assures us that it cannot be proved by…

Satan is clever. He does not only bewitch men in a crude manner, but also in a more artful fashion. He bedevils the minds of men with hideous fallacies. Not only is he able to deceive the self-assured, but even those who profess the true Christian faith. There is not one among us who is not at times seduced by Satan into false beliefs.

Obj. 2: Further, the angel was sent to administer to Tobias. Yet he said, "I am the angel Raphael, one of the seven who stand before the Lord" (Tob. 12:15). Therefore the angels who are sent, assist. Obj. 3: Further, every holy angel is nearer to God than Satan is. Yet Satan assisted God, according to Job 1:6: "When the sons of God came to stand before the Lord, Satan also was present among them." Therefore much…

Again, where St. Luke sayes of Judas Iscariot, that "Satan entred into him, and thereupon that he went and communed with the Chief Priests, and Captaines, how he might betray Christ unto them:" it may be answered, that by the Entring of Satan (that is the Enemy) into him, is meant, the hostile and traiterous intention of selling his Lord and Master. For as by the Holy Ghost, is frequently in Scripture understood…
