The Boy Who Played Priest: How Robert Prevost’s Childhood Story Became a Remarkable Papal Journey

Long before Robert Francis Prevost became Pope Leo XIV, long before his name appeared on Vatican documents and long before millions of Catholics around the world watched him step onto the balcony of St. Peter’s Basilica, he was simply a little boy growing up in the Chicago area.

And according to memories shared by his family, there were already hints of the path that would eventually define his life.

As a child, Robert reportedly loved to “play priest.” His mother’s ironing board could become an altar. Ordinary household objects could be transformed into elements of a Mass. Candies could stand in for hosts, and a young Robert would imitate the rituals he saw at church.

To his family, it was a child's game.

But it was also remarkably serious.

His brother John Prevost later recalled that Robert seemed to know from an early age that he wanted to become a priest. In one account, the future pope would even celebrate pretend Masses in the family basement, sometimes reciting prayers in Latin. Vatican media has also documented the story, noting that his brothers remembered him using their mother's ironing board as an altar.

Then there is another childhood story that sounds almost too perfectly written for history.

When Robert was about six years old, while still in kindergarten or first grade, a neighbor reportedly told him that he would one day become the first American pope.

Nobody could have known what the future held.

At the time, the idea would have sounded extraordinary. The Catholic Church had existed for nearly two thousand years, but no pope born in the United States had ever occupied the chair of Peter.

Yet on May 8, 2025, that improbable prediction appeared to come true.

Robert Francis Prevost was elected the 267th pope of the Catholic Church and chose the name Leo XIV. He became the first U.S.-born pope in the Church's history.

His brother John later recalled the old neighborhood prediction with a mixture of amusement and amazement.

“How she did that, who knows,” John said of the neighbor. “It took this long, but here he is, first American pope.”

The story is striking not because it proves that anyone can predict the future, but because it creates an extraordinary bridge between two moments separated by almost seven decades: a six-year-old boy pretending to celebrate Mass in a Chicago-area home and an adult man standing before the world as Pope Leo XIV.

A Childhood Surrounded by Faith

Robert Prevost was born on September 14, 1955, in Chicago, Illinois, to Louis Marius Prevost and Mildred Martínez. He was the youngest of three brothers, with Louis and John as his older siblings.

The family lived in Dolton, a southern suburb of Chicago, and faith was deeply woven into everyday family life.

The young Robert grew up attending church and serving as an altar boy. According to later recollections, he and his brothers sometimes woke early to serve Mass before school. In an informal conversation with children at the Vatican, Pope Leo himself remembered getting up at around six years old to serve a 6:30 a.m. Mass.

That detail is important because it adds context to the famous ironing-board story.

For Robert, pretending to be a priest was apparently not something disconnected from his everyday experience. He was imitating something he had already encountered repeatedly in church.

The rituals were familiar.

The prayers were familiar.

The role of the priest was familiar.

And, according to his family, the desire to become a priest was unusually persistent.

His brother John has said that Robert seemed to know what he wanted from a very young age. ABC News reported John's recollection that his younger brother “always wanted to be a priest” and that, as a child, he would “play priest,” with the ironing board serving as the altar.

Vatican media later offered additional details about those childhood games. His brothers recalled him “celebrating” Mass in the basement, sometimes using Latin and ordinary household items to recreate the liturgy.

For a child, it was imagination.

For the adults watching him, it was perhaps something more.

The Ironing Board That Became an Altar

There is something almost wonderfully ordinary about the image.

An ironing board is normally associated with laundry, not theology.

But in the Prevost household, it could become something entirely different when young Robert began playing priest.

A kitchen or basement could become a church.

Candy could become a symbolic host.

A young boy could stand before his family and imitate the Mass he had seen at St. Mary of the Assumption.

Decades later, those memories acquired a completely different meaning.

The future Pope Leo XIV would eventually explain that the Mass had been important to him from childhood. During an informal Vatican encounter with children, he recalled the joy he found in serving Mass even before receiving his First Communion. He also remembered the period when the liturgy was celebrated in Latin.

That childhood experience helps explain why his family's memories have attracted so much attention since his election.

People often look backward after a historic event.

A person's childhood photographs suddenly become fascinating.

Old classmates are interviewed.

Former teachers remember small details.

Family members tell stories that once seemed completely ordinary.

And sometimes, those memories reveal that the future was already beginning to take shape.

In Prevost's case, the contrast is especially powerful.

The little boy who used an ironing board as an altar eventually became a priest.

The priest eventually became a missionary.

The missionary eventually became a bishop.

The bishop eventually became a cardinal and a senior Vatican official.

And in 2025, he became pope.

The Neighbor's Remark

Then there is the prediction.
