Christianity

n. religion which is based upon the teachings of Jesus Christ and his apostles

Christianity is a monotheistic religion centered on the life and teachings of Jesus of Nazareth as depicted in the New Testament. Most Christians believe Jesus is the Son of God and the Messiah prophesied in the Old Testament, and that the New Testament records the Gospel that was revealed by Jesus. With an estimated 2.1 billion adherents, or approximately 33% of the world's population in 2007, Christianity is the world's largest religion. It is the predominant religion in Europe, the Americas, Southern Africa, the Philippines and Oceania. It is also growing rapidly in Asia, particularly in China and South Korea, Africa and Middle East.
