How do you become the pope? A 5-minute video explains the priest-to-pope career path.
A helpful explainer for non-Catholics.

Becoming pope is a multi-step process of ascending the Catholic church hierarchy.
Understanding the basics of different religious beliefs is an important part of living in a diverse world. Understanding the internal clerical or administrative structures of different religions, however, takes a bit more effort and can be confusing to those who haven't grown up within those systems.
Most of us know that the pope is the head of the Catholic church, and even people who aren't Catholic are familiar with terms like priest, bishop, and cardinal. But that's the extent of knowledge of the hierarchy for many. The holy roles and how one moves from one level to another within the Catholic priesthood can be confusing. Though the fictional movie Conclave offers a compelling glimpse into the process of choosing a new pope, the full career path from priest to pope isn't really clear for a lot of us.

Enter CGP Grey, who has a knack for explaining things simply and concisely with cool illustrations and just enough humor to make boring explanations entertaining. Grey made a video in 2013 just a month before Pope Francis was elected as the 266th pope, and it's become relevant again in 2025 with his passing.
The "How to Become Pope" video has been viewed 29 million times, so clearly this is a question of curiosity for many. Considering that there are 1.4 billion Catholics in the world and how powerful the pope is as a global figure, it's a good thing to know.

"Let's say you want to become pope, head of the Catholic church and shepherd to over one billion faithful," the video begins. "What requirements must you have for this lofty station?"
There are only two actual requirements. 1. Be a Catholic. 2. Be a man. Simple enough, right?
Technically speaking, any male Catholic could be chosen as pope, but there has never been an average Catholic person who is not part of the priesthood. In fact, it's been over 600 years since a non-cardinal became pope. So the career path for pope starts with becoming a priest, then moving up to becoming a bishop and then a cardinal.
Moving up the ladder in the Catholic church requires a lot of specific education. Becoming an ordained priest usually requires a degree in Catholic Philosophy and a master's degree in Divinity. To move up to bishop, you have to wait for a local bishop to retire or die, be on a list of potential bishops, be 35 years old, be a priest for at least five years, and generally have a PhD in theology. A congress of bishops examines the candidates for bishop, chooses one, and sends the name to the pope. The pope then approves or vetoes the choice. It's a long process.

There are about 400,000 Catholic priests in the world, according to the video, but only about 5,000 bishops. Of those bishops, about 200 are given the additional title of cardinal, which can only be bestowed by the pope.
When a pope dies or retires, the cardinals under age 80 gather together in the Vatican to elect the new pope, pretty much always from among themselves. They are isolated from the outside world in what's known as the conclave, where they go through whatever election process the previous Pope specified for choosing his successor. Typically, they vote four times a day, six days a week, and it can take weeks or sometimes even months to reach the two-thirds majority required to elect the pope.
Once the pope is elected, he chooses a new name for himself—it can be anything, but it's often the name of a previous Pope—and white smoke is released from the chimney of the Sistine Chapel, announcing to the world that a new pope has been chosen.

"So that's the career path," CGP Grey concludes, "Be born into the right half of the population, become one of a billion Catholics, then one of 400,000 priests, then one of 5,000 bishops, then one of 200 cardinals, wait for the current pope to die or retire, and convince two-thirds of your fellow cardinals to select you as the one, the only pope."
There you have it, all wrapped up in one sentence.
