Hell in Catholicism is the "state of definitive self-exclusion from communion with God and the blessed" which occurs by the refusal to repent of mortal sin before one's death, since mortal sin deprives one of sanctifying grace. Like most Christian views on hell, the Catholic view is based on Sheol and Gehenna in Judaism. The church regards Sheol or Hades as the same as hell, being the place where Jesus descended to after death.
