No. If not correct what is ruled out is what you believe Paul was teaching.If its not he correct viewpoint, then you are gutting out of the bible Pauline Justification
"Pauline Justification" actually means the understanding that Paul intended his words to convey.
Some believe Paul meant what is stated in God's Word (objective, based on the text of Scripture or "what is written")) while others believe Paul meant what it is they believe Paul's words teach
(subjective, various beliefs based on theological conclusions and revisions throughout history).
For example, Calvinism is dependent on viewing Scripture through over a millenia of theological developments and reforms to bring those conclusions closer to Scripture.
Jesus died in the stead and place of Indisual sinners, not for an entire group or a plan
This is an excellent example of what I mean by "what is written" vs "what is taught". In God's Word there are no indications that Jesus died in the stead and place of individual sinners. BUT this came to be considered what Scripture taught over centuries of theological developments and reforms (specifically the reform of Aquinas' doctrine).
As evidence, consider the fact that nowhere in Scripture is Jesus' death said to have been in our stead or place. What Scripture DOES state is that Jesus died for our sins, recieved the stroke that we deserved, it is by His stripes we are healed, etc.
There are several doctrines like this. Earlier you took for granted that the Fall changed human nature. The closest we can get to that idea, however, is that the Fall revealed human nature.
IMHO we need to be more careful with God's Word. We are all subject error, but we really should be able to at least identify what is in Scripture and what we infer from Scripture. That way we have Scrioture in common, do not elevate our understanding to the level of Scripture (and us to God), and are able to honestly discuss differences in opinion.
