9. Part II: Islam Early History of Islam Five pillars of Islam
Christianity & Islam
Early seventh c.
610. Merchant Mohammed started to receive messages from archangel Gabriel in Mecca. In less than a century Syria, Egypt, Constantinople, etc. were lost to Moslems. He started to prophecy about the religion of the one God, Allah among the Arab merchants, undermining their business much of which had to do with idols.
Nomadic tribes, no visible unity. Islam & monotheism change that. Now they have a common center. Kaaba was a pagan pantheon in Mecca where Allah, the principal god of polytheistic pantheon was worshipped. Arabic-speaking Christians use the same word Allah to mean “the deity.” Qu’ran identifies Allah with the God of the patriarchs and prophets.
In 622 he had to flee to Medina—the beginning of the Moslem era.
Eventually Mohammed gathered enough support to take Mecca. Before he died in 632 a large part of Arabia was under his control.

Christianity & Islam
Common ground:
Belief in one God who is just & good
Main differences:
Islam’s rejection of Jesus’ divinity & Trinity
Islam’s claim that Koran replaces the Bible
Jesus did not truly suffer. Jesus is regarded as one of the prophets.
Islam’s five pillars: creed, prayer 5 times a day, fast during Ramadan, pilgrimage to Mecca, almsgiving. P. 176.
Jihad: all three traditions have it: conquest of the promised Land, crusades. Jews & Christians either spiritualize the idea of the holy war: it become the battle.
Mosque of Omar. Jerusalem.

15. Holy Wars: past & present
Judaism: conquest of Canaan
Islam: conquest of Mecca
Christianity: crusades
Meanings of Holy War
Spiritual warfare
Apocalyptic battle
Physical extermination of infidels
All three monotheistic religious traditions have a version of holy war in their history. The question is, how do they use this heritage today? It is dead in Christianity (although anti-Semitism is still an issue), but it is alive and well in Islam and in Judaism among the radicals and fundamentalists.
Jihad: all three traditions have it: conquest of the promised Land, crusades. Jews & Christians either spiritualize the idea of the holy war: it become the battle of the self with the demons & temptations.
