As Pope Leo XIV begins his historic papacy, he vows to bring unity and peace to the world, promising a new era for the Catholic Church.
Pope Leo XIV began his pontificate on Sunday with an inaugural Mass in St. Peter’s Square, attended by an estimated 150,000 pilgrims, presidents, patriarchs, and princes from around the world.
Pope Leo XIV, born Prospero Lorenzo Lambertini, was an Italian Catholic priest who served as Pope from 1758 to 1776.
Born in Bologna, Italy, he was a renowned theologian and canon lawyer before his papacy.
During his reign, he issued several significant encyclicals, including 'Ex quo primum' (1759) and 'Inter sollicitudines' (1761).
He also played a key role in the Catholic Church's response to the Enlightenment.
Pope Leo XIV died on May 23, 1776, at the age of 81.
As ‘history‘s first American pope,’ Leo vowed to work for unity and become a sign of peace in the world.
The Weight of Responsibility
During the Mass, Pope Leo XIV appeared emotional when he was presented with the symbols of his office: the pallium woolen stole over his shoulders and the fisherman’s ring on his finger. This poignant moment highlighted the weight of responsibility that rests on the new pope’s shoulders.
In his homily, Pope Leo XIV emphasized the importance of love and unity in building a united church. He said, ‘I would like that our first great desire be for a united church, a sign of unity and communion, which becomes a leaven for a reconciled world.’
This call for unity is significant, given the polarization within the Catholic Church in the United States and beyond.

The Catholic Church has experienced significant polarization in recent years, driven by various factors such as clerical abuse scandals, Vatican II reforms, and differing views on issues like women's ordination and LGBTQ+ rights.
A 2020 survey found that 62% of American Catholics believe the Church is divided, while 45% feel it is 'very' or 'extremely' divided.
The polarization has led to increased tensions between conservative and progressive factions, with some calling for greater reform and others advocating for a return to traditional practices.
A New Direction
Pope Leo XIV‘s inaugural address referenced some of the themes of his predecessor Pope Francis‘ pontificate. However, he also emphasized the need for a new direction that emphasizes core truths of Catholic doctrine while remaining open to the world. He said, ‘Let us build a church founded on God’s love, a sign of unity, a missionary church that opens its arms to the world, proclaims the word, allows itself to be made restless by history, and becomes a leaven of harmony for humanity.’
Catholic doctrine is based on a set of core beliefs that are rooted in the teachings of Jesus Christ and the traditions of the early Christian Church.
The Catechism of the Catholic Church outlines the central tenets of Catholic faith, including the Trinity, the Incarnation, and the sacraments.
Key principles include the authority of Scripture, the importance of tradition, and the role of the 'Magisterium' in interpreting doctrine.
Approximately 1.3 billion people worldwide identify as Catholics, making it one of the largest Christian denominations globally.
A Message of Hope
The new pope also expressed hope for negotiations to bring about a ‘just and lasting peace’ in Ukraine. He offered prayers for the people of Gaza, particularly children, families, and the elderly who are struggling with hunger.
In his inaugural address, Pope Leo XIV set out a vision for a united church that is a sign of unity and communion. As he begins his pontificate, Catholics around the world are rejoicing at this new chapter in the history of the Catholic Church.
