I think she became a proponent of Gnosticism quite some time ago, and now she writes the same book over and over again, which can be summed up as, "Christianity isn't what you think it is. It's all about you, and the terrible Church hierarchy wants to keep you down and hold you back." It's a very New-Age sort of spin on Christianity that even the ancient Gnostics would probably not approve of.

As such, she's "all in" on Gnostic Christianity being the "authentic" Christianity. I think most scholars would disagree with a First Century composition for Thomas, and certainly few would argue that John is responding to Thomas.
