@Iconoclast,
First, you really need to learn how to use the quote feature. You have been here long enough to understand how it works.
Second, I think you mean
Roy Hargrave (was a SBC pastor from FL). I have never heard of Ray Hargrave. Are you sure about the guys name?
I think you would do better to go with Scripture rather than those men you choose to comprise your "orthodoxy".
But to do that you have to base your argument on Scripture, not commentaries.
Before dscussing Spiritual Death one must define the term. Is it simply a lack of fellowship with God? If so, then exactly when did men like Enoch gain “spiritual life”? So another term that needs to be defined is “spiritual life”.
I believe that Scripture defines both adequately. Spiritual life is that life of the “imperishable seed”, that is, “Christ in us”. It is not a spirit of natural man but the Spirit of God (I believe the order presented in 1 Cor. 15 is correct – first the natural (Adam) and then the Spiritual (Christ) as Christ became a “life-giving Spirit). So spiritual death is a state where man is absent the Spirit. It is natural man (which Paul says comes first).
Prior to discussing a state to which men were to ultimately return that state has to be defined. We cannot assume that the inverse of God's command as a pre-fall reality as that is denying the antecedent (the logic is flawed). So there is very little to stand on when it comes to redemption (if it is in fact a type of restoration) because we simply do not have enough data (Scripture) describing God's relationship to Adam pre-Fall (we do know that fellowship was disrupted by sin, and that sin separates man from God in some sense). But we cannot know the Kingdom spoken of in the Bible is what Adam experienced pre-fall in the Garden.
The idea of redemption as a remedy is problematic. While Charlton Heston played both Moses and Neville, Christ did not suffer and die as a cure for mankind. This is not a restoration but a new creation (again, first the natural and second the spiritual). Redemption freed man from the
law of sin and death, but this is not a freedom Scripture speaks of pre-Fall. Until Adam ate of the fruit he was still subject to death becoming a certainty on the day he sinned. We cannot look to Redemption as the restoration of man without making Christ (and God) subject to man. Instead, Scripture speaks of redemption as a new creation and a new birth.
If we are going to add to Scripture then we have to be very sure what we add is correct. In this case, I believe it is not. It may be old, but it is not biblica
