My point is, at best, "dead in trespasses and sins" is metaphorical, and not literal death. Literal "death" is ceasing from life in the body, and literal "spiritual death" would be ceasing from life in the soul--not Hell, but annihilation. Since it's metaphorical, at some point the metaphor breaks down. I'm not sure exactly where a Calvinist that recognized the analogy here would draw the line at which the metaphor breaks down, but I draw it at the point that says that we are incapable of doing anything, which again would be more towards death-as-annihilation, non-existance, than towards death-as-spiritual-torment, depravity.
The contrast to "made alive" 1:5; and the link and likeness of the conversion process to Christ's death, ressurrection and ascension 1:6 point to a condition worse than death row --
