The smoke was white. On May 8, 2025, the world watched the chimney of the Sistine Chapel, and suddenly, the "American era" of the Catholic Church began. But honestly, the question on everyone’s mind wasn’t just about his nationality. It was: how old is the new pope, and does he actually have the stamina to handle a Church that’s basically in the middle of a global identity crisis?
We’re now in January 2026. The Jubilee Year is officially over. Pope Leo XIV—formerly known as Cardinal Robert Francis Prevost—is no longer the "rookie" in the White House of the Vatican. He’s 70 years old.
Born on September 14, 1955, in Chicago, Leo XIV stepped into the shoes of Pope Francis at an age that, in most professions, would mean you're deep into your retirement and arguing about lawn care. In the world of the papacy? He’s practically a spring chicken.
Why 70 is the new 50 in the Vatican
To understand why people are so obsessed with his age, you have to look at what came before. Pope Francis was 76 when he was elected, and by the time he passed away in April 2025 at the age of 88, the physical toll was obvious. We all saw the wheelchair. We saw the missed homilies.
When the Cardinals entered the conclave last year, they weren't just looking for a theologian. They were looking for a marathon runner.
At 70 years old, Pope Leo XIV hits a "sweet spot" that the College of Cardinals rarely finds. He’s old enough to have the "gray hair authority" that the Church loves, but he’s young enough to potentially lead for fifteen or twenty years. If he stays healthy, we could be looking at a papacy that stretches into the 2040s. That’s a massive shift.

The Chicago kid who became Leo XIV
Growing up in Dolton, Illinois, Robert Prevost wasn't exactly planning on being the first American pope. He studied math at Villanova. Seriously, the guy has a degree in mathematics. You can see it in how he talks; he’s precise. He doesn't wander off into metaphors as much as Francis did. He’s more of a "let’s look at the data and fix the administration" kind of leader.
After Chicago, he spent years in Peru. This is a big deal for his "age profile." Because he spent so much time as a missionary and then as the Bishop of Chiclayo, he didn’t get "Vatican-ized" too early. He’s got the energy of someone who’s been on the ground, not someone who’s been sitting in a Roman office for forty years.
He’s the first pope born in the United States, but he also holds Peruvian citizenship. That dual identity makes him 70 going on 40 in terms of global perspective.
How his health compares to past Popes
People keep asking how old is the new pope because they’re scared of another long, drawn-out period of "papal infirmity."
- Pope Francis: Elected at 76, died at 88. His later years were marked by severe respiratory issues and knee problems.
- Pope Benedict XVI: Elected at 78, resigned at 85 because he simply felt he didn't have the "strength of mind and body" anymore.
- Pope John Paul II: Elected at 58 (the real outlier). He served for 26 years, but the last decade was a very public struggle with Parkinson’s.
At 70, Leo XIV is remarkably fit. He’s known for being a "workaholic" in a way that’s slightly terrifying to his staff. Since taking over in May 2025, he hasn't slowed down. He closed the Holy Door just a few days ago on January 6, 2026, and he looked... well, he looked fine. No limp, no heavy breathing at the podium.

What Leo XIV is doing with his "youth"
He’s not wasting time. While some popes take a year to find their desk, Leo XIV has already summoned the world's cardinals to Rome for an extraordinary consistory this month.
He’s tackling the Roman Curia. That’s the Vatican bureaucracy that usually eats popes for breakfast. Because he’s 70 and healthy, he has the political capital to actually fire people and move departments around. He isn't worried about his "legacy" yet; he’s worried about the "to-do list."
One thing that’s really surfaced in the last few months is his focus on the Second Vatican Council. He recently mentioned that the generation who actually lived through Vatican II is almost gone. He’s right. Being 70 means he was a child during the Council—he’s a "son" of the reforms, not a participant in the fight. That’s a subtle but huge difference in how he approaches Church law.
The "Age Gap" in the Church
There is a weird tension, though. Even though he's "young" for a pope, he’s still 70. The average age of a Catholic in Sub-Saharan Africa is under 20.
Leo XIV is trying to bridge that. He’s been surprisingly active on social media—or at least his team is. He’s the first pope who actually knows how to use a smartphone without a 12-page instruction manual. He’s trying to use his relative "youth" to signal that the Church isn't just a museum for the elderly.

What should you watch for next?
If you're tracking the papacy of Leo XIV, don't just look at the calendar. Look at his travel schedule. He’s already signaled a trip to Algeria. He’s been to Lebanon. These aren't "easy" trips. They require a lot of physical resilience.
Actionable Insights for Following the New Papacy:
- Monitor the Consistory Results: The meetings on January 7-8, 2026, will tell us if he’s going to decentralize power to local bishops.
- Watch the Appointments: Since he was the former head of the Dicastery for Bishops, he knows where the "bodies are buried." Watch who he promotes in the next six months.
- The "Leo Style": Notice the shift from the "spontaneous Francis" to the "measured Leo." He’s less likely to give off-the-cuff interviews on airplanes, which might make the Vatican PR team breathe a sigh of relief.
The bottom line? How old is the new pope is a question about more than a birth certificate. It’s a question about whether the Catholic Church can keep up with a world that’s moving at 5G speeds. At 70, Pope Leo XIV is the Church’s best bet at staying relevant without breaking under the pressure of the office.
He’s got the math degree, the missionary heart, and—at least for now—the clean bill of health to make it happen.
