Ezekiel 18, on its own, is positive proof that your proposed solution cannot be correct. The problem lies in a flawed premise. You see no meaningful distinction between physical death and spiritual death, or at best, that any such distinction is irrelevant, but that conflation is precisely where the reasoning breaks down and thereby gives you a problem that needs a solution.
But Ez 18 isn't on its own. It follows, and must be understood in context of the law, which says:
[Exo 20:5 KJV] Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God [am] a jealous God,
visiting the iniquity of the fathers upon the children unto the third and fourth [generation] of them that hate me;
This is PART OF the ten commandments (though not a part that usually gets included on wall plaques). So both must be true:
1. That God has visited the iniquity of fathers on their children for them that hate Him (Ex 20), and
2. That the people of Israel will no longer have occasion to use the parable that the father has eaten grapes and the children's teeth are set on edge. (Ez 18)
What is the concept that harmonizes the two? That the children that LOVE God are excluded from both the commandment (not "them that hate Him") and the proverb (the children that don't do wickedly, as explained in the following verses in Ez 18).
Once you let go of that single premise, the entire issue resolves itself. If, on the other hand, you cling to it, insisting that physical and spiritual death are the same, I don’t see how you can reject either the doctrine of original sin or Truescott’s central argument, which is that if original sin is true, then God is unjust.
The distinction between physical and spiritual death is a super clear and totally undeniable biblical fact...
Genesis 2:17 but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die
Adam did not die physically that day. He lived 930 years (Gen. 5:5).
It doesn't say "on the day you eat of it". It says "
in the day you eat of it". Adam indeed died physically "in that day". The phrase does not refer to a single 24 hour day, as shown in an earlier verse of the same chapter, but refers to an era of some sort.
Here is the earlier verse:
[Gen 2:4 NKJV] This [is] the history of the heavens and the earth when they were created,
in the day that the LORD God made the earth and the heavens,
If we are to believe what you say about Adam, then we must conclude that God created the heavens and the earth on one single day. But we know that isn't true. Rather, we recognize that Gen 2:4 is refering to the whole creation era, which comprised 7 days. And thus, when God says "in the day you eat of it you shall surely die" He doesn't mean just one day, but some larger number of days, perhaps even 930 years worth.
Now, since you used Gen 2:17 to claim your view is a "super clear and totally undeniable biblical fact", the foregoing has completely dismantled your basis for clarity and undeniable biblical factuality.
Therefore, some other kind of death occurred "that day"; namely, spiritual death, or the breaking of fellowship with God. This alone proves that death is not always physical in nature.
As pointed out above, this statement no longer holds, since "that day" can include more than a single day, spiritual death is no longer required.
Ephesians 2:1
And you He made alive, who were dead in trespasses and sins, 2 in which you once walked according to the [
a]course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, 3 among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others.
4 But God, who is rich in mercy, because of His great love with which He loved us, 5 even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved), 6 and raised us up together, and made us sit together in the heavenly places in Christ Jesus,
That passage hardly needs any commentary, but just to state it explicitly, Paul is speaking to people who were physically alive but spiritually dead. Thus, spiritual death is a condition of separation from God, not the cessation of biological life.
The other thing those people share is that they all were on the road to permanent death. Thus Paul can be understood to be speaking of their lasting physical death (cessation of biological life) as a foregone conclusion, except that Christ has intervened. "We were dead" can refer to the fact of their future permanent death. This kind of language is used elsewhere, as in the case of Abimelech taking Sarah to wife:
[Gen 20:3 NKJV] But God came to Abimelech in a dream by night, and said to him, "Indeed
you [are] a dead man because of the woman whom you have taken, for she [is] a man's wife."
The verse is talking about physical death, it is stated in the present tense, and Abimelech was not actually physically dead. It was a foregone conclusion that he would die because of what he had done--unless he repented (which he did).
Luke 15:24 for this my son was dead and is alive again; he was lost and is found.’ And they began to be merry.
The point is being made here is the form of typology. The prodigal son was clearly not physically dead. The father is describing estrangement, (i.e. spiritual separation), as death.
It is a form of typology, I agree. That form is called "metaphor". The son was obviously metaphorically dead to the father. In all senses that death of a son affects a father, so the prodigal was to his father. They had no relationship, he would not be in his father's future, he would not help out with his father's estate, etc. If this is what you mean by "spiritually dead", I'm completely in agreement. But it seems like you mean something else.
Ezekiel 18: 20 The soul who sins shall die. The son shall not bear the guilt of the father, nor the father bear the guilt of the son. The righteousness of the righteous shall be upon himself, and the wickedness of the wicked shall be upon himself.
21 “But if a wicked man turns from all his sins which he has committed, keeps all My statutes, and does what is lawful and right, he shall surely live; he shall not die. 22 None of the transgressions which he has committed shall be remembered against him; because of the righteousness which he has done, he shall live. 23 Do I have any pleasure at all that the wicked should die?” says the Lord God, “and not that he should turn from his ways and live?
God is not saying there that the man who repents from sin will be physically immortal, right? Of course not! He's saying that the person who repents will live - spiritually! The passage is saying that the righteous man's soul will survive his physical death.
I don't see why the passage can't be talking about physical death, just like in Abimelech's case. It wasn't that he would never die, but that he would die prematurely. Same with those who don't repent. They die prematurely--they don't necessarily get to see their grandchildren and great-grandchildren, as is promised as a reward to those who are faithful, because there will be peace in the land:
[Psa 128:6 NKJV] Yes, may you see your children's children. Peace [be] upon Israel!
Now, I could go on and on and on here, right? There are dozens, perhaps hundreds of such passages. There can be no doubt about it - physical death and not the equivalent of spiritual death. There is a very clear and deeply important difference between the two and conflating them leads to gross errors, not the least of which is the doctrine of original sin.
There is one additional point that should be made here having to do with the death of Jesus. You stated in your post that "Jesus didn't die spiritually". This is not only a denial of the very gospel itself, it openly contradicts your previous statements in the same post where you stated that "I would agree were the death and resurrection of Christ not purely a physical phenomenon, because it points to our physical resurrection INTO something both physical and spiritual, according to 1 Corp 15."
The death of Jesus physical body cannot undo the spiritual death of Adam's race, Derf!
True. It requires the resurrection of Jesus' body.
If the issue could have been solved by Jesus merely dying physically, then Jesus could have died painlessly in His sleep at the age of 102 and satisfied justice.
Neither of us know that. We also don't know whether Jesus would have died naturally at the age of 102. There is sufficient evidence to suggest that He would NOT have ever died naturally as long as He never sinned, because there is something different in His conception compared to every other human being in history. And if the father's sin causes the physical death of the son (true in Adam's descendants, as you agreed earlier), then Jesus was exempt because of His Father.
The cross, with its emotional, relational, and spiritual agony, would be totally superfluous. The fact that He endured all of it points to a deeper problem than biological death could ever account for. He was remedying the rupture between man and God.
Sure. The deeper problem is sin, which biological death is the result of.
And that's what spiritual death is, by the way. Often the objection people have when confronted with the idea that Jesus died spiritually is that it translates in their mind as "Jesus ceased to exist", which isn't the case at all.
If Jesus has a dead spirit and a dead body, and souls die, too, what is left? But I don't really have a problem with Jesus dying in such a way that no part of Him was active and alive. That seems to be what is expressed in the gospels.
None of us will ever cease to exist.
This is perhaps the root of the disagreement. What you are saying is that God created us so that we will never cease to exist, that we have immortal souls. But the whole concept of a "soul" seems to allow that it could cease to exist. Adam became a living soul when God breathed into his nostrils the breath of life. And God told him he would returned to what he was before (dust) when the breath of life was taken away, i.e., when he died.
The issue of death is not one of existence vs. oblivion, but of being in relationship with God vs. being separated from Him, of spending eternity is God's presence vs. being cast into outer darkness. Spiritual death is not the cessation of existence, but separation from God. It's alienation, exile, and loss of communion with the Source of life itself. To deny that Jesus experienced this on the cross is to gut the very heart of the gospel. He bore not just our physical fate but our spiritual condition, our estrangement from our Creator, and in doing so, He opened the door to reconciliation.
I know that's how you believe it worked. I'm saying it isn't near as clear as you are saying it is. Physical death on the cross is what seems to be necessary to reconcile the world to God. Otherwise, IT wouldn't be necessary, as you were saying. Christ could have died spiritually without all the fuss of His physical death.
If we fail to distinguish physical from spiritual death, then we cannot understand what Adam lost, what Christ restored, or what salvation actually saves us from.
I agree with this completely.
