Paul’s opinion in his letter to the Romans about salvation seems to support your view.
You would agree, I trust, that Jesus’ words out of his own mouth trump one of Paul’s letters, no?
Matthew 7:21

It's the same Holy Spirit that inspired both groups to write scripture...One group is no more authoritative than the other...
