That decision will be made by whoever is chosen pope in the conclave that will open in March of 2013.
There has never been a pope named John Paul VI.
Pope Leo IX was pope until April 19 of that year when he died. The next pope was not elected until the following year.
"They" did not change the name of the new pope, When elected, the new pope has the choice of keeping his Christian name or choosing a regnal name that he wishes to be known as while serving. When Christ named Simon as the first pope he changed his name to Peter. After Peter, the next pope to choose a new name was Pope John II who was elected in the year 533. His given name was Mercurius and he did not think it proper for a Catholic pope to be named for a pagan Roman god - Mercury.
Cardinal is the next step down in the hierarchy from the pope.
If you mean who will be the final pope, we have absolutely no idea. Pope Francis could be the last or there could be hundreds of popes after him. Only God the Father knows and he's not talking.
The next north star we are going to have is the Vega!!!
There will be no more than 120 cardinals involved in the election of the next pope.
The Black Pope's birth name is Shelly Pope.
Since Pope Francis is the first and only pope by that name, there is no need for a number after his name. If a pope in the future also decides to take the name Francis, he will become Pope Francis II and then the original Pope Francis will become Pope Francis I.
We have no idea who the final pope will be but Satan could never be a pope.
Pope Urban chose the name upon his election as pope.
If you are referring to Pope Francis, his name was Jorge Mario Bergoglio.
