Ok. I've read your assessment before of the historicity of the Bible, and for the moment I'd like to addess how you will apply this method to Plato's writings.
Was I not clear before? If I was to personally investigate ancient writings and historicity of a person or writings, I would investigate historians work on the subject and I would be looking very closely, at how they applied the historical method and how they reached their conclusions.
Since I have zero desire to investigate the historicity of Plato, I will not be doing so.
No one that I know denies that Plato existed, and yet he has only 7 or 8 works ( no originals ). Why is this ? I assume that you accept Plato existed without any investigation, as you stated.
As I already stated, I have no opinion on the historicity of Plato, because I have not investigated the same. For this reason, I wouldn't make the mistake of assuming anything.
Oh I'll need a source for this-
"But, as time has gone on, there has been good objective historical analysis applied to the NT and even some Christian historians agree, the NT is mostly a work of theology, as opposed to a work of historical credibility."
I am not going to turn this thread, into an apologetics thread in regards to historicity of the NT. If you want sources on historicity of the NT, google will provide you with more than you could handle. Simply google; historicity of the NT.
Now, as I have stated before, I was a Christian for a long time and never really investigated the NT in any serious way and actually started my investigation, with the thought of getting clarity and support from the NT.
What happened from that point, was not anticipated, regarding what my investigations discovered and took me down a road, I could not ignore, because the evidence was something I could not ignore.
Lastly, I am the type of person, who rolls over every rock in an attempt to investigate any topic. I don't settle for the source that may be comforting, I devour everything I can get my hands on, from various sources and when it comes to the NT, it involved; consuming the work of conservative Christian historians, moderate historians and liberal historians. After a while, it became clearer to me, which of these people, applied the historical method in the most objective way, which is what was important to me.
