Everyone has an ultimate starting point, Paul. What do you think of God's self-revelation? Should we trust it 100%, or just a little bit until we can find some 'outside' verification? What about Christ's self-attestation? And how do we verify the inerrancy of the Bible from ‘outside’ without leading to an infinite regress of appeals?
I think this is and always has been a very personal thing, some people require ONLY The bible while others need to reconcile the bible with what science tells us ( and by science I mean archeology, astronomy, physics, etc), other need to reconcile the bible with how it is interpreted, and so forth.
Like you said, everyone has a starting point and mine is that YES, we do have the words of God in the bible but that bible is not JUST the words of God but also the History of a people and it was written by ancient man for ancient man and it's various books were written as genre's and the bible is not A book but a collection of books of various writers, it is a progressive revelation of God and God's will, a will that is accomdating to the people it is been spoke to.
Can you post these verses please, Paul?
Jeremiah 8:8
8 How can you say, “We are wise,
and the law of the Lord is with us,”
when, in fact, the false pen of the scribes
has made it into a lie?
As for Christ,
Matthew 23 goes into great detail Jesus' issues with the scribes ( and some of the Pharisees).
Mark 12 and Luke 20 also.
While Christ isn't as "in your face" as Jeremiah that accuses them point blank of lying, Jesus does accuse them of hypocracy.
I don't think this is a case of "the scribes have lied and written falsehoods in the bible", but that Christ was accusing them of selective interpretations in their writings to justify things that they wanted to prioritize, case in point:
6 “Woe to you, blind guides, who say, ‘Whoever swears by the sanctuary is bound by nothing, but whoever swears by the gold of the sanctuary is bound by the oath.’ 17 You blind fools! For which is greater, the gold or the sanctuary that has made the gold sacred? 18 And you say, ‘Whoever swears by the altar is bound by nothing, but whoever swears by the gift that is on the altar is bound by the oath.’ 19 How blind you are! For which is greater, the gift or the altar that makes the gift sacred? 20 So whoever swears by the altar, swears by it and by everything on it; 21 and whoever swears by the sanctuary, swears by it and by the one who dwells in it; 22 and whoever swears by heaven, swears by the throne of God and by the one who is seated upon it.
23 “Woe to you, scribes and Pharisees, hypocrites! For you tithe mint, dill, and cummin, and have neglected the weightier matters of the law: justice and mercy and faith. It is these you ought to have practiced without neglecting the others. 24 You blind guides! You strain out a gnat but swallow a camel!
While I don't think that these things call into question the authority of the Bible, they do call into question the authority of those that were responsible for the transmission of the bible.
The warning of "test all that you are taught", is a valid one.
