If I may ask one question first. Is death only physical? When Jesus said "let the dead bury the dead" what did He mean?
Oops that was actually two questions.

Forgive me.
Forgiven.
Of course, your questions are on target, but what does "spiritually dead" mean and include or not include?
Reading these threads,
does the phrase mean something different to different traditions?
Why does someone from a certain tradition think they're telling others some great alternate tradition punishing truth by proof-texting and telling us Paul says you were dead in trespasses and sins?
The issue for me comes about in reading all the input in these posts.
We have not only the corpse complete inability being demanded from a dichotomy theology saying the Spirit needs to make alive our corpse soul/spirit before we can believe.
We have another dichotomy system with a dead or non-functional spirit (not soul) saying the Spirit essentially takes the place of the dead or non-functional human spirit so we can believe (which is not far from the dichotomy of the corpse soul/spirit)
Then we have trichotomy with the human spirit still intact and functional essentially saying we have all we need to believe the grace provisioned content God provides and draws us to.
We have all three of these different views talking about being '"spiritually dead".
So, is the human spirit alive or dead? What happened at the fall?
I think it was
@Pilgrimshope who listed Scriptures that very much seem to speak of the existence of a functional(?) human spirit.
If it's alive or functional in any way, then should we be saying we're spiritually dead which everybody seems to be using?
If "spiritually dead" means dead but not physically dead, then what is dead or what does Paul mean we were dead?
There is another seemingly more Biblically accurate phrasing we use often to parallel or explain the "spiritually dead" construct. When Paul speaks of being dead in trespasses and sins, what is he drawing on and what does he mean (your question back to you)?
I'm not picking on you BTW, just answering questions with more questions and open posting for anyone who cares to read?
We are all way more traditionalized than any of us sufficiently understand. We're using made up phrases and made-up words which are all open to opinion and abuse and we're arguing about words that are not even in the Bible. Few are just explaining the Text.
