I'm, afraid I don't support anything that is detached from matter - for me thoughts are material, imagination is material etc
I know what you mean but thoughts are immaterial. Immateriality doesn't mean something is metaphysical. Computer software is immaterial for instance. That's why materialists prefer the term physicalism.
What materialists/physicalists disagree with theists is that some immaterial properties in our minds are produced by something metaphysical (soul).
Theists defend that this soul is not just immaterial but immortal and independent from the physical body. And is active even after the death of the physical body (and some immaterial properties of the mind that are dependent on the body) .
The theistic view I support says that soul is not our whole minds but is attached to our minds and give it the property of consciousness (and Qualia for example) . We believe this entity (soul) was infused (directly by God) in Homo sapiens not so much time ago (about 4000 bC). Before that Homo sapiens were not conscious but they had a very sophisticated mind able to develop writing and civilization, you can read more about how this is possible in the psychological thesis of Bicameralism by Julian Jaynes.
