Ellen White once used the term "the eternal Godhead"...

I recently stumbled upon a passage which disturbed my beliefs in the Father and Son a little bit. There is a passage in the Spirit of Prophecy which might shock any non trinitarian. Ellen White wrote the following in "The Upward Look" on page 148 paragraph 4: "The eternal Godhead - the Father, the Son, and the Holy Ghost - is involved in the action required... ."

I read it and immediately a question popped into my mind: Why on earth has no trinitarian ever quoted this passage to us? Since this was written in 1904 (Ms 45) it would be a cementing block for the official church statement of fundamental belief No 2.

So I started searching the complete published writings of Ms 45 from 1904 was anywhere else quoted. But I wasn't able to find the full document. Only parts of it could be found. Here a bit and there a bit. So I wrote to the White Estate if it would be possible to obtain a full copy of this manuscript. They kindly send me a copy and I started reading. Luckily I was sitting on a chair. Why? Because this is what she wrote, according to the copy from the White Estate:

"The Father, the Son, and the Holy Ghost, the eternal Godhead is involved in the action required..." and so forth.

Now a bunch of thoughts went through my mind. Why the "misquote" on the official CD-ROM? What is the exact difference between writing "the eternal godhead" before or after the Father, Son and Holy Spirit? Maybe you guys who speak english as your mother language can help here? What exactly does she mean?

At least I got an answer to my question why no one ever quoted this passage to us. Or didn't I?
