Very interesting debate. I also agree about the personality contrast, too.
Similar to Mr. Sungenis, I struggled with fully understanding the repeated comment made by Mr. Hester about “contradictions in tradition and scripture”. Ultimately. I believe he was trying to allege that Catholic Tradition is antithetical to Sacred Scripture - a charge that I believe would take more lengthy discussions, maybe talking about specific doctrines. Dr. Hester mentioned a few of these supposed unbiblical doctrines such as infant baptism.
I’ve heard or read other non-Catholics state something similar: if a Catholic doctrine is not obviously found in the Bible, it must be based on Tradition alone and therefore, unbiblical. Of course “obviously found” is based on one’s interpretation of what the Bible says and so any Catholic who attempts to use the Bible to defend a doctrine, or at least show it is not contrary to what the Bible expresses, will likely butt heads with a different, and equally thoughtful and scholarly, interpretation. To me, this is an obvious problem with sola scriptura.
I was intrigued how Mr. Hester apparently agrees that support for doctrines are not always clearly laid out in the Bible citing both explicit and implicit evidence.

Again, I’m not sure how much this helps his case since someone has to decide how much evidence is enough.
