I do indeed discount the entirety of Mark. However, I don't really think my personal view is too relevant. I'm more interesting in helping you bolster the inner consistency of your argument, even if I disagree with it. For the sake of discussion, I am willing to entertain the idea that some parts of Mark may hold accurate information. I'm merely interested in how you determine which parts are accurate and which parts are not. In this instance, you suspect that some parts are insertions or edits and you use other passages within the same work to bolster this claim. I'm wondering how true this contradiction between verses really is and, if it is a necessary contradiction, I have two and a half follow-up questions: 1. How do we know that the verse in question is the edit and not the other verses you use to discredit it? 2. How would the insertion come about and, if it had to be intentional, why would someone intentionally add this part to the text?
