Thanks for the references. The second one (John) makes no reference to sin, however. If you are linking it to the first quote, then that would be your interpretation.

With regard to Paul, we would have to understand what he meant by sin. You chose to end your quote at v 11. However, the text continues from v 12 onwards to connect Jesus with Adam. That's worth thinking about, and what the deeper meaning is.

The concept of sin may not be what Christians think, i.e. a question of moral behaviour. In my view, the reconciliation refers to forgiveness for Original Sin, i.e. that souls chose to descend to the material world, thereby entering a world where there is physical death. They have therefore abandoned, at least temporarily, their original immortal nature. It was Original Sin that separated souls (thus humans) from God.

That is not a view that Paul seems to share, at least at the surface level of the text – he refers to Adam as “one man”. The rest of the text, however, seems to link Jesus to the text of Genesis chapter 3, therefore in line with my interpretation. Paul's original intention may have lost something in translation.
