SDA Belief No.17 - 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.)
