I just asked this question:
I imagine it should be on topic because I have a sense that local expertise is applicable. However, I’m not aware of a precedent, so I decided to look in the the help center:
If your question is about...
- interpretation of a specific Bible passage
- hermeneutical approaches
- translation of Biblical texts
- historical context (with regards to a particular text)
- source criticism
... then this is the right place to ask.
The topic of textual criticism was addressed on meta, and the conclusion was that it is on topic.* We have a tag textual-criticism which appears to be mostly appropriately applied. Among the questions I’ve looked through, though, all pertain to a specific passage. I think such questions were the focus of the prior meta question.
In the same way that exegesis and hermeneutical approaches are both on topic, I expect that applied textual criticism and the theory† of textual criticism are both on topic. Is this correct?
* We probably should add a bullet to the above.
† Can’t think of a better word, although this doesn’t seem to be especially theoretical. Guidelines for textual criticism?
