 Although a significant restatement of the published beliefs took place in 1980 General Conference session, the church has chosen to leave the doctrinal statement on the Investigative judgment virtually unchanged from its formulation in the 1870s.The constitution of the Adventist Theological Society affirms the doctrine of the Investigative Judgment.Official Adventist publications such as "Seventh-day Adventists Answer Questions on Doctrine" (1957) and "[Seventh-day Adventists believe]" (1988) defend the church's traditional teaching.
