"However, what I'm asking for is the sacred document that clearly reveals this doctrine you have named?"
Does all theism have to be based on a sacred document? Besides, most theistic evolutionists are Christian.
Yes, I agree with that.
However, their thoughts on this subject are pure speculation. There is no sacred text that reads "out" this notion. It is an idea that can only be read "into" the text.
This is the interpretive fallacy known as eisegesis.
I don't want to belabor my point, though. The bottom line is that theistic evolutionists have no supporting revelation. They made it up. They needed evolution to fit creation, so they came up with this answer that has "God guiding the evo process."
There is nothing, however, in sacred Christian scripture that SAYS such a thing.
