Dispensationalism Definition

dĭspĕn-sāshə-nə-lĭzəm
noun
A doctrine prevalent in some forms of Protestant Christianity that divides history into distinct periods, each marked by a different dispensation or relationship between God and humanity. Dispensationalism further holds that Christian believers will be transported to heaven without warning and that soon thereafter there will be a period of tribulation, followed by the Second Coming.
