In the recent conversations about the Seventh-Day Adventist Church, it was brought to my attention that the SDA considers founder Ellen G. White a true prophet.  They even state it in their Foundamental Beliefs (emphasis mine):

18. 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.)

Her writtings are a continuing and authoritative source of truth?  My first reaction to that was, “Yikes, this cannot be happening!  They even put this in their belief statement :S  How in the world can they do that?!?”  This sounds awfully close to what Paul said in 2 Tim 3:16-17: “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness,  that the man of God may be competent, equipped for every good work.”  It’s very interesting that the last sentence in the above quote feels like it’s just thrown in there as a just-in-case-anybody-objects… creating a double standard of authoritative truth.

Are White’s writtings an authoritative source of truth OR is Scripture the sole authority for life and faith?  This is probably a question that many SDAs struggle with.  If you know me, you probably know where I stand here.  Enough said.

Recently, Pulpit Magazine has been posting a series of articles by John MacArthur on Prophecy and the Closed Canon:

There is no fresher or more intimate revelation than Scripture. God doesn’t need to give us private revelation to help us in our walk with Him. “All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; that the man of God may be adequate, equipped for every good work” (2 Tim. 3:16 – 17; emphasis added). Scripture is sufficient. It offers all we need for every good work.

Christians on both sides of the charismatic fence must realize a vital truth: God’s revelation is complete for now. The canon of Scripture is closed. As the apostle John penned the final words of the last book of the New Testament, he recorded this warning: “I testify to everyone who hears the words of the prophecy of this book: If anyone adds to them, God shall add to him the plagues which are written in this book; and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the tree of life, and from the holy city, which are written in this book” (Rev. 22:18–19). Then, the Holy Spirit added a doxology and closed the canon.
