Being the only Adventist here I beleive Refiner has the best grasp on Adventist beleif. The 1844 event to Adventists is the great dissappointement When they beleived jesus would come no SDAs beleive anything of an invisible comming in 1874 this was a splinter group.
The SDAs have reinterpreted the 1844 event as being the beginning of the investigative judgement where the books of record are examined to determine who will be saved.
All adventists now beleive the second comming is in the future and a visible event.
The investigative judgement in 1844 is seen as the antitype of the day of atonement in the jewish system.
Today only the very conservative SDAs beleive in the investigative judgement as it was originally taught no SDA theologan will put his name to such an idea. The mainstream members while giveing lip service to the doctrine understand it in a far more gospel way because most beleive when a person becomes a christian he passes from death to life.
While I go to a mainstream church I support 'Good News Unlimited a splinter group of Adventists who have left such doctrine as an investigative behind in the dustbin of failed doctrine.
In fact there are many such splinter groups in adventism But much of the conflict between differing groups is now in the past. Barry
