Prophecy in the Seventh-day Adventist ChurchSeventh-day Adventists believe that Ellen G. White, one of the church's co-founders, was a prophetess, understood today as an expression of the New Testament spiritual gift of prophecy.
Seventh-day Adventist believe that White had the spiritual gift of prophecy, but that her writings are a lesser light to the Bible, which has ultimate authority. According to the 28 Fundamentals the core set of theological beliefs held by the Seventh-day Adventist Church, states that Adventists accept the Bible as their only creed and can be read online on the website of the Seventh-day Adventist Church.
The 18th of the 28 Fundamentals states the Adventists viewpoint on the Gift of Prophecy: :"One of the gifts of the Holy Spirit is prophecy. This gift is an identifying mark of the remnant church and was manifested in the ministry of Ellen. G. White . As the Lord's messenger, her writings are a continuing and authoritative source of truth which provide for the church comfort, guidance, instruction, and correction. They also make clear that the Bible is the standard by which all teaching and experience must be tested. (Joel 2:28, 29; Acts 2:14-21; Heb. 1:1-3; Rev. 12:17; 19:10.)."
According to one church document, "her expositions on any given Bible passage offer an inspired guide to the meaning of texts without exhausting their meaning or preempting the task of exegesis". In other words, White's writings are considered an inspired commentary on Scripture, although Scripture remains ultimately authoritative.
Adventist believe she had the spiritual gift of prophecy as outlined in Revelation 19:10. Her restorationist writings endeavor to showcase the hand of God in Christian history. This cosmic conflict, referred to as the "Great Controversy theme", is foundational to the development of Seventh-day Adventist theology. Provided by Wikipedia
