Christianity

Christianity is a monotheistic religion based on the life and teachings of Jesus of Nazareth as presented in the New Testament writings of his early followers. It is the world's largest religion, with an estimated 2.1 billion adherents, or about one-third of the total world population. It shares with Judaism the Hebrew Bible (historically called by Christians the Old Testament), and for this reason is sometimes called an Abrahamic religion along with Judaism and Islam.
