However, the Iliad is never said to be true, and we found out that it was. With the Bible, however, either it is true or it isn't. You can't take only part of the Bible as divine and the other parts human. If you did that, you might as well take the entire Bible only the work of humans, not inspired by God.
Unfortunately Jar is no longer here to raise this, but I have to ask, which bible are you referring to? There are dozens of different bibles and canons used by different Christian churches around the world.
In your mind, which one is the only one that is all divine?
