With regards to Paul his writings are inspirational, his reasoning is sound, his logic solid.

I believe that he was led by the holy spirit in his quest.

Paul would not have liked it if people used his writings as a hammer to beat people into uniformity of thought and opinion with regards to the sincere search of truth. That is why he commended the Bereans and that is why he spoke of the liberty we have in Christ.

Scripture was not yet canonized when these writings were written. The "holiness" of scripture could be comprimised by the compilation of texts into a canon.

That is why certain books are included and others excluded, I do not attribute this effort to God but to men who use their reasoning faculties and historic knowledge to try with best intent to compile scriptures for record, edification and historic preservation.

We can claim it is canonized by God but we cannot prove it. That is why we must lean on truth discovery through knowledge of the written word, which we must examine critically, because truth does not fear criticism or investigation because through-out this process we discover it to be even more true than we originally had hoped or believed. Trancending truth from faith to certainty. Milk to meat.

So if I challenge scripture it is not to defy it though it may appear to be the case.

It is to challenge the ones who thought they had a sure footing and to throught the argumentative process see if we can discover something we had not taken into consideration before.
