Interesting Church History Papers

I have been browsing this site recently, and it has some good material. I especially interested in the period of the Western Schism, where there were two or three claimants to the papal office at any particular time. This caused a traumatic decline in the prestige of the papacy. This is important for Reformation history because a council, that of Constance, elected a new pope and deposed the other three popes, in other words, a council was in an important sense superior to the pope, because a council selected a pope after John XXIII abdicated. This adds a little context to what a "council" or "free" council is when Martin Luther mentions the need for a council. It is one not convened by the pope, but one in which the pope is a participant and not a judge, like Constance. Anyway, have a look, there is some interesting stuff there.
