The investigative judgment, the pre-Advent Judgment, (or, more accurately the pre-Second Advent Judgment) is a unique Seventh-day Adventist doctrine, which asserts that the divine judgment of professed Christians has been in progress since 1844. It is intimately related to the history of the Seventh-day Adventist Church and was described by one of the church's pioneers Ellen G. White as one of the pillars of Adventist belief. It is a major component of the broader Adventist understanding of the "heavenly sanctuary", and the two are sometimes spoken of interchangeably.
