1. Good question, The true author of the Bible is God so it is subjective in his view because he is a supreme being with his own views but He is the Truth. He offers objectivity in to human thoughts and nature. It is tricky but I guess it depends on what we are defining as being objective.
Yes, but God didn't do his own work, did He? Even the most devout Christian must concede that He worked through human beings, subjective human beings, in order to get the Bible written.
We know that humans are subjective, and even if we accept that they were inspired by God, we must also recognize that such inspiration
did not remove their subjectivity.
How do we know this? Simple -- the writing styles are different. Had God's inspiration overridden their free will, all 66 books of the Bible would read like they were written by the same author -- God. We know God is eternal and unchanging, so His writing would similarly be eternal and unchanging.
That's not what we see in the Bible -- so even if we accept that God told them
what to write, they maintained enough free will to choose for themselves -- subjectively --
how to write it.
So it turns out the Bible is subjective, after all -- unless "inspired" is a euphemism for "mind-controlled drone"?
2. Priests, pastors and ministers are subjective
3. I am subjective.
Indeed -- and you, the priests, pastors, and ministers, and even the Bible authors had nothing to work with except a very subjective medium to capture and express Divine Truth -- human speech.
Do you
really think that the infinite Truths of the all-powerful eternal Creator of the heavens and Earth can be perfectly, completely expressed in our finite language -- let alone the finite language of thousands of years ago? I've said it before -- it's like trying to play Beethoven's Fifth Symphony on a kazoo.
Do yourself a favor -- don't mistake the kazoo for the symphony.
