You all miss the point. In character the prophet of the continents largest, most powerful religion is likely going to have a massive reason to believe they have superior theological knowledge. Would people from other religions agree? Probably not but by the same token he, and the religion he heads aren't going to think that anyone can argue theology on a equal footing, which was the point of the original post. To call such a figure a mere "student" in term of theology is a massive insult to the Prophet and the religion in general. This isn't the modern age remember, it is unlikely that most religions consider others to have any validity, or respect the knowledge of their priests.
The whole Dwilight University and its foundations are pretty modern themselves. The institution promotes such kind of values, so it would be expected that in the institution other's points of view would be, if not considered, at least respected. It may be not very medieval, but nor is the guild. Who would have thought about a theology department in the middle ages with Catholics, Orthodox, Jews and Muslims for example? It would be madness at least, or deep heresy at worst.
