Pope Leo XIV faces limits on changing the Catholic Church - but Francis made reforms that set the stage for larger changes

Cardinal Robert Prevost of the United States has been picked to be the new leader of the Roman Catholic Church; he will be known as Pope Leo XIV.

Attention now turns to what vision the first U.S. pope will bring.

Change is hard to bring about in the Catholic Church. During his pontificate, Francis often gestured toward change without actually changing church doctrines. He permitted discussion of ordaining married men in remote regions where populations were greatly underserved due to a lack of priests, but he did not actually allow it. On his own initiative, he set up a commission to study the possibility of ordaining women as deacons, but he did not follow it through.

However, he did allow priests to offer the Eucharist, the most important Catholic sacrament of the body and blood of Christ, to Catholics who had divorced and remarried without being granted an annulment.

Likewise, Francis did not change the official teaching that a sacramental marriage is between a man and a woman, but he did allow for the blessing of gay couples, in a manner that did appear to be a sanctioning of gay marriage.

To what degree will the new pope stand or not stand in continuity with Francis? As a scholar who has studied the writings and actions of the popes since the time of the Second Vatican Council, a series of meetings held to modernize the church from 1962 to 1965, I am aware that every pope comes with his own vision and his own agenda for leading the church.

Still, the popes who immediately preceded them set practical limits on what changes could be made. There were limitations on Francis as well; however, the new pope, I argue, will have more leeway because of the signals Francis sent.

The process of synodality

Francis initiated a process called “synodality,” a term that combines the Greek words for “journey” and “together.” Synodality involves gathering Catholics of various ranks and points of view to share their faith and pray with each other as they address challenges faced by the church today.

One of Francis’ favorite themes was inclusion. He carried forward the teaching of the Second Vatican Council that the Holy Spirit – that is, the Spirit of God who inspired the prophets and is believed to be sent by Christ among Christians in a special way – is at work throughout the whole church; it includes not only the hierarchy but all of the church members. This belief constituted the core principle underlying synodality.

Francis launched a two-year global consultation process in October 2022, culminating in a synod in Rome in October 2024. Catholics all over the world offered their insights and opinions during this process. The synod discussed many issues, some of which were controversial, such as clerical sexual abuse, the need for oversight of bishops, the role of women in general and the ordination of women as deacons.

The final synod document did not offer conclusions concerning these topics but rather aimed more at promoting the transformation of the entire Catholic Church into a synodal church in which Catholics tackle together the many challenges of the modern world. Francis refrained from issuing his own document in response, in order that the synod’s statement could stand on its own.

The process of synodality in one sense places limits on bishops and the pope by emphasizing their need to listen closely to all church members before making decisions. In another sense, though, in the long run the process opens up the possibility for needed developments to take place when and if lay Catholics overwhelmingly testify that they believe the church should move in a certain direction.

Change is hard in the church

A pope, however, cannot simply reverse official positions that his immediate predecessors had been emphasizing. Practically speaking, there needs to be a papacy, or two, during which a pope will either remain silent on matters that call for change or at least limit himself to hints and signals on such issues.

In 1864, Pius IX condemned the proposition that “the Church ought to be separated from the State, and the State from the Church.” It wasn’t until 1965 – some 100 years later – that the Second Vatican Council, in The Declaration on Religious Freedom, would affirm that “a wrong is done when government imposes upon its people, by force or fear or other means, the profession or repudiation of any religion. …”

A second major reason why popes may refrain from making top-down changes is that they may not want to operate like a dictator issuing executive orders in an authoritarian manner. Francis was accused by his critics of acting in this way with his positions on Eucharist for those remarried without a prior annulment and on blessings for gay couples. The major thrust of his papacy, however, with his emphasis on synodality, was actually in the opposite direction.

Notably, when the Amazon Synod – held in Rome in October 2019 – voted 128-41 to allow for married priests in the Brazilian Amazon region, Francis rejected it as not being the appropriate time for such a significant change.

Past doctrines

The belief that the pope should express the faith of the people and not simply his own personal opinions is not a new insight from Francis.

The doctrine of papal infallibility, declared at the First Vatican Council in 1870, held that the pope, under certain conditions, could express the faith of the church without error.

The limitations and qualifications of this power include that the pope be speaking not personally but in his official capacity as the head of the church; he must not be in heresy; he must be free of coercion and of sound mind; he must be addressing a matter of faith and morals; and he must consult relevant documents and other Catholics so that what he teaches represents not simply his own opinions but the faith of the church.

The Marian doctrines of the Immaculate Conception and the Assumption offer examples of the importance of consultation. The Immaculate Conception, proclaimed by Pope Pius IX in 1854, is the teaching that Mary, the mother of Jesus, was herself preserved from original sin, a stain inherited from Adam that Catholics believe all other human beings are born with, from the moment of her conception. The Assumption, proclaimed by Pius XII in 1950, is the doctrine that Mary was taken body and soul into heaven at the end of her earthly life.

The documents in which these doctrines were proclaimed stressed that the bishops of the church had been consulted and that the faith of the lay people was being affirmed.

Unity, above all

One of the main duties of the pope is to protect the unity of the Catholic Church. On one hand, making many changes quickly can lead to schism, an actual split in the community.

In 2022, for example, the Global Methodist Church split from the United Methodist Church over same-sex marriage and the ordination of noncelibate gay bishops. There have also been various schisms within the Anglican communion in recent years. The Catholic Church faces similar challenges but so far has been able to avoid schisms by limiting the actual changes being made.

On the other hand, not making reasonable changes that acknowledge positive developments in the culture regarding issues such as the full inclusion of women or the dignity of gays and lesbians can result in the large-scale exit of members.

Pope Leo XIV, I argue, needs to be a spiritual leader, a person of vision, who can build upon the legacy of his immediate predecessors in such a way as to meet the challenges of the present moment. He already stated that he wants a synodal church that is “close to the people who suffer,” signaling a great deal about the direction he will take.

If the new pope is able to update church teachings on some hot-button issues, it will be precisely because Francis set the stage for him.
