Now, about 'the grave'.
According to the bible, not only does the body go into the grave, but so does the soul.
Because thou wilt not leave my soul in hell, neither wilt thou suffer thine Holy One to see corruption. -
Acts 2:27
The word 'hell' is 'ades (Hades) and means the grave.
Jesus died, and was buried - He entered the grave. His body, obviously, was in the grave, yet according to scripture, so was His soul.
Now, you have said this:
"The body (Gk. Soma) is the physical part of a person. The soul (psueche) is the seat of the thoughts and emotions (psyche). "
This is false. It is false in two ways - biblically, and scientifically.
It is false biblically because as I have said the 'soul' is not merely the 'mind' of a person, but is the person themself.
It is false scientifically because the 'thoughts and emotions' are seated in the brain and not some mystically, ephemeral 'soul' as you posit. Now science is based on provable theories. This theory CAN BE PROVEN.
Hit yourself in the head with a hammer, causing brain damage, and see if your thoughts and emotions are affected - or even STOPPED. See? the brain is where the thoughts and emotions are.
Guess what? God knew about this even before the neuro-biologists came on the scene. Look here:
His breath goeth forth, he returneth to his earth; in that very day his thoughts perish. -
Psalm 146:4
When a person dies, their thoughts PERISH. The Psalmist understood this, neurobiology has proven it, and thus the theory you are espousing is shown to be in error.
Otherwise, alcohol would have no effect on the THOUGHTS and PASSIONS of a person who imbibes too much. What happens when you drink alcohol? The alcohol acts first as a CNS stimulant then (as more is taken in) a CNS depressant. Not only are motor actions affected (vision impaired, speech slurred, equilibrium messed up) but THOUGHTS and EMOTIONS are affected (often adversely).
Same thing with psychoactive substances such as mescaline or LSD. Although almost no motor function is affected with those drugs, the thought processes ARE DEFINITELY AFFECTED. I am not talking about 'seeing things' I am talking about rational thoughts and mental perceptions of the meanings of things.
All this goes to show that the seat of thought and emotion is the BRAIN, a very physical part of the human being.
This does not mean thought ORIGINATES ENTIRELY and ONLY in the brain, but rather that thought EXISTS in the medium of the brain, influenced by both the physical (brain engrams) and spiritual (the spirit of the individual, the spirit of God, other spirits, etc).
This, by the way, is the REASON FOR THE RESURRECTION.
Why must we be RESURRECTED in order to finally enter into eternal life? Because persons are SOULS, produced by the uniting of flesh and spirit. Thus, the body will be raised (changed, actually) and re-united with spirit, to produce a LIVING SOUL (only this time, it will be bearing the image of the Second Man and not the First).
Otherwise, there is NO NEED FOR A RESURRECTION. We can all just jump out of our bodies at death, enter into Heaven, and la-te-da for eternity - no resurrection business needed.
Obviously, that is not the case. There will be a resurrection. 'In my flesh I shall see God.' (so testified Job).
Hades is called 'HADES' because it is "a-" (not) "idou" (visibility, idea, thought, perception). The place of 'no thought, no perception'.
Like the Psalmist declared - in that day, his thoughts PERISH.
