As Forest Keeper knows, all my arguments with him are from scripture. Unless the teachings of the Church are misrepresented or history is misrepresented, in which case I would naturally refer to the authority of the Church or to the historical facts. When I explain the error of Protestantism to a Protestant I would do it from scripture only, since that is the only way to have a productive discussion with a Protestant. It is not hard to do: your entire theology is drawn from a few passages from St. Paul taken out of context and contradicts the entire scripture read in context.

Imagine that: the word of God being the final arbiter between men. Sadly, it is a concept that the church in Rome has yet to learn, even if her members pretend Sola Scriptura for the sake of discussions with Protestants.
