No, it is not proved false by one exception. Valla nearly faced the inquisition for exposing the truth regarding the Donation of Constantine. Long before that recorded in the documentation of Vatican I if memory serves is the record of an Archbishop noting the anathematizing of pope against pope.. the raising then throwing out of infallible decrees by the popes and councils, etc to the point where when he finished speaking the Council arose and shouted "heretic".
Because he did nothing more than quote right out of church history. It is the truth. The Church of Rome hunted down and slaughtered one group just for making them look bad. They preached everything Rome preached but did so under a vow of poverty and under the direction of scripture without so much as a 'by your leave' from the church. The problem is that these men wandering about in poverty made the poshness of the Pope and the rest of the church out to be excess and corruption - not by their words, but by stark contrast of action. So they had to be destroyed. Care to guess who it was.

Try these semantics games with someone who doesn't know the history. Ope, that was possible in the dark ages, I forgot, it's not as possible to hide the truth today.
