I quoted Paul in context. Address the context.
Alright:
Just to be clear: the false doctrines of Inherited Sin teach that children are spiritually condemned because of the sin of Adam.. but I reject that doctrine.
What is the reason that Jesus said the kingdom of heaven belongs to the children?
It is because they are obedient to the truth: they walk in the light and they do not rely on deceit (because they are easily busted, that keeps them accountable). That doesn't last forever though, as we know that a time comes when they do begin to rely on deceit in order to not walk in the light. They reject The Spirit of Truth in that decisive moment and they are taken captive by their sin (see Romans 6:16).
So that is how Romans 7:9-11 comes to say that "I was alive once, until sin took advantage of the commandment and through it, killed me" - just as St. James says in James 1:14-15 that it is our desires that lure us into sin, and that death follows.
In Christian terms, we say that a person who is walking in the darkness is not doing the truth, and must be born again else they are already judged according to John 3:19-20. They are unable to see the kingdom of God because they have been put to death spiritually - remaining only as carnal and not having any discernment of the spirit (1 Corinthians 2:14-15, Revelation 3:20).
The key that reveals the error in the doctrine of Inherited (Imputed) Sin, is where St. Paul says "I was alive once". That goes against what the Original Sin doctrine teaches, that says we are born spiritually dead. You can see that it directly contradicts the scripture of Romans 7:9-11. But there are other scriptures that teach the truth of James 1:14-15, and they also need to be twisted in order to fit the doctrine, the main one being Romans 5:12 - where the key distinction between your view and my view, is what we understand in the word "spread":
How did the death
spread to all? .. you say it is "imputed", but I say it is "invoked" and the main difference is in the right of God to condemn us for the sin:
If we are condemned because of the imputation of a sin that someone did 6,000 years ago, then there is no justice in that, but if we are condemned because we have chosen to follow our desires to the detriment of righteousness, then justice is empowered to judge us for the decision we made.
Romans 5: NASB
15But the free gift is not like the transgression. For if by the transgression of the one the many died, much more did the grace of God and the gift by the grace of the one Man, Jesus Christ, abound to the many.
16The gift is not like
that which came through the one who sinned; for on the one hand the judgment
arose from one
transgression resulting in condemnation, but on the other hand the free gift
arose from many transgressions resulting in justification.
17For if by the transgression of the one, death reigned through the one, much more those who receive the abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.
This is saying that because we are being redeemed to life after having known the true cost of our sin, then we are wiser to not fall as in James 1:14 again - and in this way, the gift of grace that came to the world through Christ abounds more than the sting of death that came to the world through Adam.
18So then as through one transgression there resulted condemnation to all men, even so through one act of righteousness there resulted justification of life to all men.
19For as through the one man’s disobedience the many were made sinners, even so through the obedience of the One the many will be made righteous.
20The Law came in so that the transgression would increase; but where sin increased, grace abounded all the more,
21so that, as sin reigned in death, even so grace would reign through righteousness to eternal life through Jesus Christ our Lord.(NASB)
There’s a reason original sin was an early church doctrine. Because it was apostolic teachings. There’s no wiggle room in the above text to suggest otherwise.
I don't agree. Some of the writings of the early church fathers did fail to accurately convey the teaching of Christ and His apostles. This doctrine is the most primary of the heresy, that they didn't seem to have foreseen the subtlety of the error that their writings were leading to.
we are all under condemnation for the one transgression.
I cannot support you in saying that. It is because you have used the word "for" to suggest that God holds us personally responsible for Adam's sin, whereas if you had said "through" or "as a result of", then it would be an acceptable statement (in an isolated context).
