Every tradition has unique ways of expressing theological issues in Scripture.
This seems to have occured in some traditions of "spiritual death".
I suspect tradition as men built theory on theory to smoothe out the biblical narrative.
We certainly need to guard against tradition. Firstly, we must fight against the 150+ year old tradition of not understanding what the Puritans used to call the 'sinfulness of sin.' Secondly we must guard against the more recent tradition of regarding everything written by those who went before us as unworthy of regard (unless of course, we think it might help our argument ). Thirdly, there is the tradition that unfortunately has grown up on this board, of calling the Biblical views of those one disagrees with 'traditions' as a smear and to avoid having to deal with them seriously.The danger is when people do not recognize the stories for what they are and build on the fiction.
But we must deal, first and foremost, with the Scriptures. First of all, we can all agree, I hope, that mankind is by nature dead in trespasses and sins (Ephesians 2:1-5 etc.). But this death is not a physical death, since sinners are very much alive, so what sort of death is it? It is a spiritual death. So what does that mean? It means that the unsaved have no spiritual life in them; they cannot react positively to the things of God (1 Corinthians 2:14). So people do not die spiritually for the very good reason that they are born spiritually dead.
And yet we are told, 'Truly, this only I have found: that God made man upright, but they have sought out many schemes' (Ecclesiastes 7:29). The Hebrew word for 'man' here is Adam. The Hebrew word which the KJV translates as 'upright' is yashar. As @The Biblicist has pointed out, the word is translated as 'righteous' nine times. Also, God is described as 'upright' in Psalms 25:8; 92:15, and His 'testimonies' as 'upright' in Psalm 119:138. It would therefore be possible, I think, to translate Ecclesiastes 7:29 as '.....God made Adam righteous, but men have sought out many schemes.'
Now let's look at Genesis 2:16-17. '.......Of every tree of the garden you may freely eat; 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.' Now there is no sense in one can imagine God adding, "And if you don't eat of it you are still going to die!" No, No; the corollary of Gen 2:17 is that if Adam did not eat of the tree he would not die. If he did not die, he would have lived forever q.e.d.
Now if 'the wages of sin is death,' how can it be argued that Adam was created a sinner? It makes no sense. 'The wicked are estranged from the womb; they go astray as soon as they are born......' (Psalms 58:3). If Adam was created a sinner, he was under sentence of death from Day One.
I have more to add, particularly on the 'sinfulness of sin' and God's detestation of it, which makes it utterly impossible for God to have created a sinner and then call His creation 'very good.' But this will have to do for the present time.
