Shut-door theology was a belief held by the Millerite group from 1844 to approximately 1854, some of whom later formed into the Seventh-day Adventist Church. It held that as William Miller had given the final call for salvation, all who did not accept his message were lost. The door of salvation was shut, hence the term "shut door". They later understood it was concerning the sanctuary and not the events on earth so abandoned their earlier understanding. As an interpretation of the year "1844", it was connected to the investigative judgment belief, which forms one of the official 28 Fundamentals beliefs today. History After the disappointment of 1844, the Millerites held a Conference in 1845 in Albany, attended by 61 delegates, to determine the future course and meaning of the Millerite movement.

The Seventh-day Adventist Church officially formed in 1863, so they still were known as Millerites or as "Adventists" or "Second Adventists" till they organized. When Jesus did not arrive the Millerites who held to the 'Shut door' belief felt there was something which had to explain the delay. The understanding of the investigative judgment was given after the Great Disappointment when Hiram Edson, after a night of prayer, had "an impression or a vision" that explained why Jesus had not come: the sanctuary needed to be cleansed and a review of the records in heaven needed to be completed before Christ would appear. Those Millerites believing in the Shut door theory did not believe it necessary or possible to reach out to the lost, who had rejected Miller's final call. Salvation was only open to those who had accepted the message of William Miller. The groundwork for the theory came from a William Miller quote published in the December 11, 1844 Advent Herald: "We have done
