From the 13th to 15th centuries, the size of the College of Cardinals never exceeded thirty, although there were more than thirty parishes and diaconal districts which could potentially have a titular holder; Pope John XXII (1316—1334) formalized this norm by limiting the College to twenty members. In the ensuing century, increasing the size of the College became a method for the pope to raise funds for construction or war, cultivate European alliances, and dillute the strength of the College as a spiritual and political counterweight to papal supremacy
Just like my earlier example of Royal Edicts there could be a Papal Edicts that may institute certain holy laws that could make things easier, or worse, depending. The only person with control of this would be the Pope (Player controlled if currently player's character is currently in that position). Aside from that, the Pope does the usual stuff such as approving crusades, excommunicating, etc.
