God exists, and He is holy - that's unanimous amongst theists.
Not actually. Some theists are polytheists. Some think the creator of the universe was an evil deity.
Those that are monotheists are in agreement that their imaginary friend is the bestest. But anything past that is up for grabs.
They all recognize the spiritual warfare that takes place in every human's mind.
Again, far from universal, although common in monotheist religions. Although often that is also a form of dualist (a good deity and an evil one).
So, again, not the sort of agreement that would be expected if there was actually something that they all witness.
Again, the comparison to color blindness is instructive. All color aware people agree that a green object is green, even though a color blind one doesn't see the difference with red.
They all agree that something cannot come from nothing.
That has nothing to do with a supernatural.
Each theist asserts that man is created in the image of God - spiritual endowment
They all accept both the teleological and cosmological arguments
Again, this is far from universal. It is, in fact, a derivation of Platonic and Aristotelian philosophy. Those theisms without that history don't hold to those doctrines.
Therefore, i have no idea what you're talking about in regard to lack of consistency?
Maybe you need to look at the variety of religious viewponts people have and have had. Even the Bible shows a change in views of what the main deity is like over time (did Jacob actually wrestle with God and win?).
