What NN is referring to is the scientific principle of falsification: you cannot prove something correct, you can only falsify a theory, i.e. prove it wrong. This however does not apply to pseudo sciences, such as theology, for you cannot prove anything right or wrong using the same test as the original researche in order to see if you can falsify it. E.g. how do you prove God exists? You cannot, but neither can you prove he does not exist. In theology we use therefore the Bible as our point of reference: it has to be in the Bible for it to be correct. To say, “God says it” is invalid unless one can show that it is in the Bible, unless of course one wants to start a cult.
NN cannot prove his thesis for it is not in the Bible, neither can Mark, wherefore they use the scientific principle of a hypothesis: they begin with the assumption that the man’s authority exists in the Bible and set out to prove it. This works in science, but not in theology.
