I think I understand your view, I just need a bit more clarification (I think).
Isaiah 59 presents:
But your iniquities have made a separation between you and your God,
And your sins have hidden His face from you so that He does not hear.
And as a result of the ongoing sins:
Therefore justice is far from us,
And righteousness does not overtake us;
We hope for light, but behold, darkness,
For brightness, but we walk in gloom.
And just a bit later he states:
Transgressing and denying the LORD,
And turning away from our God,
Speaking oppression and revolt,
Conceiving in and uttering from the heart lying words.
Now the reason I am pursuing the mater is that it seems the sins and iniquities were a purposed determined turning away from the light of God.
Therefore, Isaiah declares that because when God looked:
And He saw that there was no man,
And was astonished that there was no one to intercede;
And as a result, God provided for the need:
Then His own arm brought salvation to Him,
And His righteousness upheld Him.
He put on righteousness like a breastplate,
And a helmet of salvation on His head;
And He put on garments of vengeance for clothing
And wrapped Himself with zeal as a mantle.
What man refused to do, God did.
Now, I gave all this to show both your foundation statement of sin separating is valid, but doesn't Isaiah teach a bit different WHY folks sin?
Here Isaiah is teaching that the sins and iniquities are the cause of separation. Not that the separation is the cause for the sins and iniquities. This is a bit at odds with how you presented, but never-the-less there is that estrangement that is common to all.
David may be used to show that before birth, one is conceived in iniquity, but is that iniquity of the deed that brings about the conception, or is it the conception is itself iniquitous, or that conceived is iniquitous.
Augustine held (IF my memory isn't faulty) that the act of husband and wife was iniquitous, and therefore all that resulted from that act was "born iniquitous." That is one reason for his hold on infant baptism.
However, Isaiah seems to place the emphasis upon the purposed and determined turning of humankind from God resulting in the iniquity and sin that separates. First the turning, then the sinful life.
I bring up Isaiah because John uses the same sequence. Folks purposely turn from God (the light) - the result being, their deed are evil and they don't want them exposed so they shun, mock, don't understand ... God (the light).
Again, it is a really small matter, for all have sinned.
However, I am just not certain that Augustine was not persuaded more by his background than he was by actual scriptural principle.
There comes a time when every person who had a belly button chose or will choose to sin, except Christ. Just as Adam chose to sin (though he didn't have a belly button).
Previously, Adam had no propensity to sin, no nature or desire for sin, but like all men, purposely and determinedly chose to turn from God, to separate himself from God, to hide from God.
Therefore, all babies are not separated from God, but are as Adam, before he consumed that which was forbidden. They have no propensity to sin, no desire to sin.
There doesn't need to be some generated "safe" or as Augustine believed, safe because of heritage. But safe (no condemnation) because they just have no sin, that child has not chosen as Adam but will by nature of Adam to one day purposely choose to sin.
Just for clarification, I do embrace much of the doctrines of Grace, I just consider some areas need to be better aligned with the teaching of Scriptures.
Therefore, does not the Scriptures teach that humankind certainly are born with a nature that one day will choose to sin, but remains without sin until such maturity of intellect and personality obliges that nature to be disclosed in choosing iniquity rather than God. And at that point, just as the first Adam, that person is separated by their own choice from God.
Another example may be in the statements as to the formation and fall of the enemy of believers. He was perfect in every aspect, until iniquity was found in him. That purposed choice that all humankind make to turn from God, to separate themselves from God and God confirming that separation, being first found in the enemy of believers.
Just asking.![]()
We each will have to conclude as to how we view the condition of man when he comes into this world. If we conclude that "babies are not separated from God," then we establish a reason by which we would find error in Scripture, because we are told of man's condition in terms which do not allow for relationship with God whatsoever (for example, Romans 3:10-18).
You say...
Previously, Adam had no propensity to sin, no nature or desire for sin, but like all men, purposely and determinedly chose to turn from God, to separate himself from God, to hide from God.
...which states two different things, really.
I think it is without question that Adam could, and did...sin. Eve was deceived, but Adam was intentional in his sin. That shows a propensity for sin, effectively cancelling out the statement following.
Therefore, does not the Scriptures teach that humankind certainly are born with a nature that one day will choose to sin, but remains without sin until such maturity of intellect and personality obliges that nature to be disclosed in choosing iniquity rather than God. And at that point, just as the first Adam, that person is separated by their own choice from God.
Not at all. The above states the exact opposite of what Scripture teaches. The concept that men are in relationship with God and only come under condemnation after they grow up and sin conflicts with a very basic truth: God only is righteous, Holy, and Just, and man is not like Him.
Even if we speculated about a person being born and being able to live in such a manner where he never sinned once...this does not mean they qualify for entrance to God's presence, or could be considered to be in relationship with Him. This would also conflict with Christ's teaching that His death for the world was necessary.
Scripture on all points denies a relationship between God and fallen man, and necessitates the demand for sacrifice for sin.
Not even babies are afforded a position of righteousness which equals that of God. Even babies are in need of the imputed righteousness of Christ.
God bless.
