Christianity is the world's largest religion, with 2.8 billion adherents. It is categorized as one of the three Abrahamic or monotheistic religions of the Western tradition along with Judaism and Islam. 'Christian' is derived from the Greek christos for the Hebrew messiah ("anointed one"). Christianoi, "followers of the Christ," became the name of a group who followed the teachings of Jesus of Nazareth in 1st-century Israel and proclaimed him the predicted messiah of the prophets.
