Since we are the "Sola Scriptura " crowd, i would point to the extensive protestant study of the Holy Scriptures. I myself have read, and continue to read bible studies from some incredibly talented, highly educated bible historians. I use several concordances, bible dictionaries, and greek/english dictionaries. The one thing that i do know, from my readings of those most learned, of both protestant and Catholic stripe, is that what we have today as our Bibles are incredibly acurate. There are those who debate the versions of the old testament hebrew scriptures used, just as some debate which version of new testament autographs are the most acurate translation, but when all is weighed, the acuracy of the Holy Scriptures is amazing. In my opinion this is the work of the Holy Ghost.
Where we fallen men go astray is when we grab bits and pieces of scripture without understanding the full context, both textual and historical.
