Christianity is an Abrahamic monotheistic religion based on the life and teachings of Jesus of Nazareth. Its adherents, known as Christians, believe that Jesus is the Christ, whose coming as the messiah was prophesied in the Hebrew Bible, called the Old Testament in Christianity, and chronicled in the New Testament. It is the world’s largest religion with about 2.4 billion followers.


Christianity remains culturally diverse in its Western and Eastern branches, as well as in its doctrines concerning justification and the nature of salvation, ecclesiology, ordination, and Christology. Their creeds generally hold in common Jesus as the Son of God—the logos incarnated—who ministered, suffered, and died on a cross, but rose from the dead for the salvation of mankind; as referred to as the gospel, meaning the “good news“, in the Bible (scripture). Describing Jesus’ life and teachings are the four canonical gospels of Matthew, Mark, Luke and John with the Jewish Old Testament as the gospel’s respected background.
