The world’s largest religion is based on the life and teachings of Jesus as described in the New Testament. Believers, called Christians, consider Jesus the Son of God, whose Crucifixion served as atonement for all human sins and whose Resurrection assures believers of life after death. The original Christians were Jews who believed that Jesus was the Messiah promised in the Hebrew Bible; other Jews disagreed, however, and eventually Christianity became distinct from Judaism as the Apostle Paul and others spread the faith to gentiles.
