Christianity is divided into a multitude of sects. The breadth of Christian belief and practice is enormous, reaching from the highly ritualistic Orthodox and Catholic Churches to other more austere Protestant ones and many many other small or large groups that defy easy categorization. The central tenet of Christianity is that Jesus Christ is God; specifically, "God the Son" incarnated as a human on Earth in order to suffer, die and rise from the dead as a repayment to God for human sin. The sin in question is explained in the Bible as Eve's eating of a forbidden fruit from the Tree of Knowledge, some 6,000 or so years ago. Under the "New Covenant", anyone who believes in the Son of God can, by accepting this, dwell at God's side in Heaven in the eternal afterlife. All others will be tortured for all eternity.
