Compare and Contrast essay: Christianity, Islam, and Judaism Introduction of Religions Christianity most widely distributed of the world religions, having substantial representation in all the populated continents of the globe. Its total membership may exceed 1.7 billion people. Islam, a major world religion, founded in Arabia and based on the teachings of Muhammad, who is called the Prophet. One who practices Islam is a Muslim. Muslims follow the Koran, the written revelation brought by Muhammad. The Muslim world population is estimated at more than 1 billion. Islam is the quickest growing religion. Judaism is one of the world's oldest religious traditions. Pre-modern Judaism constituted (and traditional Judaism today constitutes) an integrated cultural system of Jewish law, custom, and practice encompassing the totality of individual and communal existence. It is a system of sanctification in which all is to be subsumed under God's rule. Judaism originated in the Middle East, but Jewish communities have existed at one time or another in almost all parts of the world, a result of both voluntary migrations and forced exile or expulsions. Origin The central element of Christianity is the person of Jesus Christ. Jesus of Nazareth, a Jewish rabbi, attracted a following of people who believed him to be a new prophet. Their recollections of Jesus' words and deeds recall his days on earth and the miracle of his resurrection from the dead on the first Easter. These Jewish Christians began the first churches, in Jerusalem. Much like Christianity Islam was based on the prophesies and teaching of person or prophet, Muhammad. In Mohammed's time (570?-632), the Arabian Peninsula was inhabited by nomadic Bedouins and city-dwelling Arabs. Muhammad began his ministry at the age of 40, when, he claimed, the archangel Gabriel appeared to him in a vision. At first Muhammad confided his visions only to his family and close friends.
