"I have a problem with anything doctrinal that is outside the bounds of logical interpretation of the New Testament."
And you got this doctrine of the supremacy of the New Testament uber alles from...?
(It's certainly not in the New Testament.)
Like say a church council that decided on the canon of the Bible?
I dont consult the New Testament for economics, just for theological purposes. My faith dictates that I follow the Bible. I am sorry I cannot say the same about yours.
