What precisely does she say that is being portrayed as “scripture” that needs to be added to the canon? What does she say that is new revelation?
“Sabbath moments.”
Start with that. She is practically saying “Thus sayeth the Lord.”
As I recall she has based her unbiblical ecumenical ideas either on dreams or direct revelation from God (hardly a novel approach in our day), but I’m not spending the time to dig out any specifics.
Ten or eleven years ago I was concerned over what she was teaching my wife and the women in our former church, so I spent many hours listening to her, reading her, and generally studying her ministry. Her pervasive influence played a part in us finding a new church home soon thereafter. Other than the occasional article I read, I’m unwilling to dedicate any more time to her. I know what I need to know for my family, my teenage daughters, and the group of men with whom I have some spiritual influence.
Bottom line for me: she isn’t all bad, but I strongly disagree with some of her theology, disagree with some of her methods, and believe she is careless with the Word of God. As is so often the case, all I can do is sound the alarm. If you disagree with me and don’t mind her teaching your wife, proceed accordingly.
