Ellen White founded the Seventh-day Adventist church and members must vow
to believe that she was a prophet! From the 27 Fundamental beliefs, #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."

The most potent blasphemy of Ellen G. White:
On page 481 of 'Great Controversy' (1927 ed.) Mrs. White says, "When Christ by virtue of His own blood removes the sins of His people from the heavenly sanctuary at the close of His ministration, He will place them upon Satan, who in execution of the judgment, must bear the final penalty."
What does the Bible say?
1 Peter 2:23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously:
24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
If a SDA follower believes Ellen G. White in the above statement, they are damned to hell. There is no hope for them.

There is no repentance and believing as an event of conversion in White's gospel:
"Do you desire to become a follower of Christ, yet know not how to begin? Are you in darkness and know not how to find the light? Follow the light you have. Set your heart to obey what you do know of the word of God. His power, His very life, dwells in His word. As you receive the word in faith, it will give you power to obey. As you give heed to the light you have, greater light will come. You are building on God's word, and your character will be builded after the similitude of the character of Christ."
This is a Gnostic gospel, a works or process gospel.
