47-year-old Consolata Missionary Bishop in Mongolia to Become the Youngest Cardinal

A Consolata missionary Bishop who has ministered in the East Asian nation of Mongolia for nearly 20 years will soon become the world’s youngest cardinal.

At 47 years old, Bishop Giorgio Marengo is the same age that Karol Wojtyła was when Paul VI announced that he had been selected to join the College of Cardinals.

The Italian-born Bishop will receive a red hat along with 20 other new cardinals at a consistory on Aug. 27, just two years after his episcopal consecration.

“This is a huge surprise for me,” Marengo told Vatican News the day after the pope’s announcement.

“For me, living this new vocation will mean continuing on the path of littleness, humility and dialogue,” he said.


Originally from northern Italy's Piedmont region, Marengo has spent the past 19 years serving as a Consolata missionary priest in Mongolia.

Pope Francis named him the Prefect of Ulaanbaatar, Mongolia’s apostolic prefecture, in 2020. After a meeting with the pontiff, Marengo said that Pope Francis was “very interested in the … the Church in Mongolia and of the Mongolian people in general.”

“We know how much the pope cares about the entire Church, even those areas where there are not large numbers, indeed precisely where the Church is more in the minority," he said.

Mongolia has a population of about 1,300 Catholics in a country of more than 3 million people. The Prefecture Apostolic of Ulaanbaatar serves the entire country.

While serving as a Consolata missionary in Mongolia, Marengo established a new catechesis program. He told CNA in 2014 that the program sought to form young adults into future catechists by providing lessons in theology and the Church and its mission.

"I believe being a bishop in Mongolia is very similar to the episcopal ministry of the early Church," Marengo said.

"The Church is a very small reality, it is a minority but there is this group of Mongolian faithful who have chosen, with great courage and also a sense of responsibility, to follow the Lord and become part of the Catholic Church."

The first modern mission to Mongolia was in 1922 and was entrusted to the Congregation of the Immaculate Heart of Mary. But under a communist government, religious expression was soon thereafter suppressed, until 1992.

In 2002, the Ulaanbaatar mission was elevated to the present apostolic prefecture. The mission's superior, the late Fr. Wenceslao Padilla, a priest of the Immaculate Heart congregation, was appointed prefect, and was consecrated a bishop the following year. Padilla died in September 2018. Mongolia's first native priest was ordained in 2016.

Marengo told Vatican News in 2020 that because Mongolia's Catholic community is so small it is especially important to pay attention to interreligious dialogue and the cultural traditions of the Mongolian people.


"It means dedicating time to know and study the language, to refine those tools that allow us to enter into a true dialogue with people, to understand their points of reference, their history, their cultural and religious roots," he said.

"And at the same time, in all this, to be faithful to the Gospel itself … to offer with great humility, with great sincerity this precious pearl we have received which is the Gospel of the Lord."

Marengo grew up in Turin, Italy, studied theology at the Pontifical Gregorian University in Rome, and later obtained a license and doctorate from the Pontifical Urbaniana University.

He chose "Respicite ad eum et illuminamini" as his episcopal motto, which means "Look to him and you will be radiant."

Until the consistory in August, the current youngest cardinal is 55-year-old Cardinal Dieudonné Nzapalainga of Bangui.
