Are questions regarding methodological approaches in biblical hermeneutics welcome in this group?
I would add a small qualification to the other answers. The primary purpose of this site is the interpretation of biblical texts. Within that framework, discussion of interpretive methodology is absolutely relevant. On the other hand, if the question involves a discussion of the methodologies themselves, that may be more relevant to other sites such as Christianity.
For example, consider the role of source criticism in the study of the gospels. A question exploring how source criticism helps us understand the varying forms of the Lord's prayer in Matthew and Luke would certainly be valid. But a general question asking if source criticism is a reliable methodology in the first place may not be valid, because it does not relate to the interpretation of specific texts. The precise wording of the question may be an important issue.
