Since you've done so much research on this particular subject, Vince, you may already be aware of these sites. But if not, these do a much more thorough job of giving the apologetics answers to the points you brought up than I ever could (especially since I don't necessarily agree with them, LOL)
Now, those two appear to be the standard Fundamentalist answers. This last one, I have personally bookmarked for further reading:
The reason I bookmarked it is because in just quickly skimming the article for the section referring to Paul, I read this:
It is widely held today that the Bible is flawless and without error. It is believed that the Holy Spirit wrote the Bible directly through the pens of inspired men. The Bible is often called "The Word of God." It is also a widely held belief that to doubt any part of the Bible is to reject the whole thing. These beliefs may sound good, right, and noble; yet they are in error. The Bible was written by men and men err. It's that simple. It is true that the Bible for the most part was written by great men of God who were inspired to write. But it is incorrect to believe that these great men suddenly became perfect while writing the Bible. God does everything He can for man, but He is still limited by man's imperfections and disobedience. This limitation does not suddenly vanish when men write scripture.
And I agree with that wholeheartedly. I'm interested to read what else the author has to say.
