There is not changing of the Bible. That remains stationary. What is changed is our understanding of what the Bible is saying. If the divergence is too great then it can be seen that the interpreters of the Bible have gone too far.
Why is 'remaining stationary' desirable? Shouldn't the Bible be corrected when edits, copy errors, mistranslations, &al are discovered? Wouldn't that be a good thing? Shoudn't, at least, the interpretations be amended?
Sceptics always claim that interpreters of the Bible go too far to agree with science.
What does "go too far to agree with science" mean? Does that mean interpreters shouldn't take historical, archaeological or linguistic
facts into consideration when interpreting?
Isn't an interpretation an opinion? What should that opinion be based on? -- a personal agenda, divine inspiration, or
facts, ie: the best current knowledge?
Science is always right even though it keeps changing.
No! Not 'always right', more like "usually the best current understanding based on the most reliable, tangible evidence."
I know that science is not always right and that looking into what happened in the past can be a source of many errors and imo is not real testable and repeatable science anyway.
That's why scientific facts are always provisional, and why science is always looking for new evidence to clarify, test and improve it's interpretations.
The Big Picture rarely changes, it just becomes sharper as more pixels are added. This 'change' does not make the picture suspect or invalid.
If not scientific methodology, what methods do you advocate for judging, interpreting or testing religious scripture, or any writing, for that matter?
