It's out there, but at the moment I can't pin it down. Might have been in The Guru Papers or another book which looked into ACIM, or perhaps on the "Skepdic" website. Obviously the theology of ACIM reveals that she was not new to CS and metaphysical literature. Now, I did just read a couple days ago that the original ACIM "urtext" gives specific kudos to Mary Baker Eddy, [i:afcf9f529c]by name.[/i:afcf9f529c] I suggest a Google search. That's how I found this stuff, after some Googling and following links.
If I find the specific pages again, I'll certainly post the links in this thread.
As for Christian Science and Scientology, of course they're different! However CS is clearly dangerous and destructive in its own way. I lost a friend 30 years ago, for whom a simple operation would have saved his life. He was CS so he refused medical attention. He died, slowly and painfully. That may have been his choice, but it was a foolish and selfish one, because his family and friends suffered for his choice as well. End of that story.
EDITED TO ADD:
From (of all places) Wikipedia:

[i:afcf9f529c]One Urtext passage that was not included in the published version calls Christian Science "clearly incomplete," but praises one of the observations of Christian Science founder Mary Baker Eddy. This is Eddy's observation that while the Bible describes how Adam, while in the Garden of Eden was put into a deep sleep, nowhere does the Bible ever describe that Adam was awakened from that sleep. This same observation about Adam is also made within the pages of ACIM.[/i:afcf9f529c]
So Helen WAS exposed to CS and the writings of Eddy. More elsewhere, as soon as I track it down again...
(One must remember that material on Wikipedia is suspect, due to the input from anonymous and unattributed authors and editors. Personally, I can see hints of redaction from ACIM devotees in the entry on the book.)
