[Wh40k] Are the Saints the Emperors version of demons?

This might be some A grade heretical heresy, but bear with me.

So, living saints are People that through their faith gets some fancy golden powers from the emperor to fight his enemies with. This sounds a lot like demonic possession, a smaller part of a major god that takes over a host and gives them new powers. So, are living saints like the emperors demons?

Saints are living beings, capable of excersizing their own will at any stature and get their abilities through the holy faith in the God emperor of mankind, Deamons are tiny parts of the greater chaos gods. 

So saints are granted powers, Deamons are the powers, kinda.
