Spiritual "death" is separation from God, and describes the soul. Corpse comes from the human understanding of "dead". When one dies a physical death, their soul becomes separated from their body. When one is spiritually dead, their soul is separated from God. The calvinists' use of "corpse" would also have to be attributed to "dead to sin", also, making a true believer unable to sin, which we know is not the case. In John 11 we see a physically dead person respond to the Word. What makes anyone think that a spiritually dead person is unable to respond, too?
Let's look at three NT stories of Jesus' raising the dead: The young man in Luke 7, the daughter of Jairus in Luke 8, and Lazarus of Bethany in John 11. In each case, Jesus "quickened" them, then spoke directly to them. The reason they could respond is that Jesus had made them alive. They possessed no ability of their own to respond until they had been given life.
They were, in effect, regenerated.
Here is the spiritual analogy. Paul, in Ephesians 2:1 said, "you hath he quickened who were dead in their trespasses and sins. Even when were were dead he quickened us..." We are in effect, regenerated, so that when the Holy Spirit illuminates us, convicts us, draws us, we are able to, yea desire, to freely respond in repentance and faith.
When we were lost, we were, as Paul put it, dead IN our sins, not dead TO sin.
You might answer, Oh but dead corpses can do neither right or wrong. They can please God and they can't sin. The answer is that the spiritually dead are not physically dead, thus able to feed the sinful desires of the flesh. John 1:13 clearly and unequivocally states that whose who are born again are not regenerated by their wills, but by God.
This is the Calvinist view, that when one responds in repentance and faith to the call of Christ, it is because God has given him the ability to do so. And God has also given him the freedom to desire (that is, to will, to want) to respond.
This may seem to have strayed from the OP, but it speaks directly the question of how to define total depravity.
