I think the crux of the problem is that with all the statements the Bible makes, at a plain reading of the text, who are we, as mere humans to decide which parts should be strictly adhered to, or which parts should not, or which parts mean something completely different from the plain reading? As far as I can tell there is no consistent application of logic and understanding what parts matter and which parts do not. And depending on who you talk to, those parts
change.
I understand that as part of the faith, it is not our place to know the reason God has chosen. However, I believe that there are very serious concerns about the intentions of the people 'qualified' to interpret the texts. Relying on "just trust us" gets us into big trouble, fast.
As the saying goes, the devil may quote scripture too.
