I am not going to debate angelology tonight, but I would concede that it is more than slightly possible from what I have heard.
As far as the hair is concerned, the way that I understood it was used was as a sign of concecration when used in prayer. However, that was more from Bro. Stoneking. I have never read Sis. Reider's books on the topic.
I have never heard the fall of Satan used as a major tenant for the not wearing of jewelry, but would be willing to listen to a case be made for that position. I consider Paul, Peter, Isaiah, Jeremiah, and Ezekiel to be quite suffiecient for God frowning on jewelry. Especially as I have learned how it was used for more than simple ornamentaion.
And as can easily be seen by this exchange, he definately has the two of us confused.
