Based on a variety of previous questions, it seems that specific authorship of many parts of the Bible are not known for sure.
For example (though I realize there are traditions of who wrote what):
- Job
- Ruth
- Esther
- Hebrews
Question(s):
Why is specific authorship considered important (eg the on-going scholarly debates over who wrote the epistle to the Hebrews)?
Is it important?
When is it important?
note - I am not looking for direct answers to canonicity, but for whether specific authorship is important
