Now, Trump and Pope Leo, respectively ensconced in their disparate spheres of influence, reign as the paramount American figures, each wielding significant power within their distinct domains.

The newly elected American global leader espoused, as his dictum, the imperative "Fight!", whilst his pontifical counterpart inaugurated his papacy with the inaugural, world-facing utterance: “Peace.”

The divergence between President Donald Trump and the Chicago-born pontiff, Pope Leo XIV, is utterly profound across the political spectrum, personal attributes, and their respective Weltanschauungen; their leadership operates within distinct capacities and spheres of influence.

However, Leo's epochal election last week to assume leadership of the world's 1.4 billion Catholics, marking the first instance of a US-born pontiff, signifies that the two most potent individuals globally are now Americans, a circumstance that precipitates inquiries into the amplitude of American sway during an era when Trump's protracted tariff disputes and peremptory pronouncements have destabilized eight decades of entrenched global order and ignited a palpable skepticism among allied nations vis-à-vis the United States.

The perceived geopolitical implications of an overweening American influence are widely posited as a significant contributing factor for the Catholic Church's historical reticence, spanning nearly two and a half centuries, to elect an American to the papacy – a pattern only recently disrupted by the elevation of the former Cardinal Robert F. Prevost of Chicago, now Pope Leo XIV, to the 267th pontificate last week.

“The paradox inherent in Leo's election is that it will likely be perceived globally as an emblem of optimism – a figure capable of articulating their aspirations rather than pursuing policies detrimental to their interests,” remarked David Gibson, who directs Fordham University’s esteemed Center on Religion and Culture.

Pope Leo represents a distinct American archetype on the global stage.

The astonishment and exultation surrounding the obscure cardinal's elevation to the papacy swiftly segued into a vigorous debate concerning the plausibility of two Americans concurrently occupying the apex of the global hierarchy.

Trump's well-documented aversion to yielding primacy, palpable in his "America First" foreign policy paradigm, seemingly resonated with a significant swathe of American Catholics, who opted for his candidacy over that of his Democratic competitor, Kamala Harris.

Conspicuously, in a seemingly calculated overture to this demographic, Trump disseminated an image, ostensibly conjured by artificial intelligence, depicting himself arrayed in papal vestments during the period of public grief following the demise of Pope Francis on April 21st; this gesture, however, met with palpable disapprobation among certain segments of the Catholic and Italian populace, prompting Trump to disavow personal responsibility for the image's posting, assert that those who took umbrage were simply incapable of appreciating humour, and adamantly maintain that "the Catholics were unequivocally enamoured of it."

Despite this, Trump extended his felicitations to Leo and deemed it an "extraordinary privilege" that the pontiff hailed from the United States.

Pope Leo, concurrently, is, in a sense, also a political figure, exhibiting a composed demeanor and adopting the tactic of engaging his fellow cardinals in intimate huddles preceding the conclave, according to sources. Although he was born in Chicago, Leo — then Prevost — dedicated two decades to missionary work in Peru before his appointment by Pope Francis in 2023 to preside over the Vatican's influential dicastery charged with the rigorous scrutiny of episcopal candidates globally.

Precedent exists for pontifical engagement in global affairs, as exemplified by Pope John Paul II's widely acknowledged role in contributing to the dissolution of communism; however, Leo assumes the papacy having previously expressed public dissent, notably via social media, regarding Vice President JD Vance, the most prominent Catholic figure in American politics, thereby indicating a pre-existing ideological schism with the current administration on contentious policy domains including, but not limited to, immigration – a cornerstone of Trump's platform – and environmental matters.

Following a trajectory reminiscent of Trump's media engagement, Leo, during his Monday address in Vatican City, emphatically advocated for the liberation of incarcerated journalists and underscored the collective imperative to defend the invaluable tenets of free speech and press freedom, a stance notably divergent from Trump's consistently adversarial approach to the journalistic profession, spanning from official government interactions to legal confrontations.

The leadership styles of Trump and Pope Leo occupy distinct conceptual strata.

At the nascent stage of February, Leo, who at that juncture retained the surname Prevost, disseminated an excerpt from a Catholic journal bearing the title, "JD Vance's Assertion Erroneous: Christ's Teachings Do Not Mandate a Hierarchisation of Philanthropy."

This transpired several days subsequent to Vance — a neophyte to Catholicism — expounding upon immigration during a Fox News interview through the prism of a Christian dogma positing a hierarchical prioritization: first one's family, followed by one's neighbor, then one's community, thence one's compatriots, and only thereafter, according precedence to the remainder of the world.

Addressing the throngs congregated within St. Peter's Square in Italian, Leo articulated an alternative paradigm for the ecclesiastical body and human interaction: "We must constitute a Church operating in concert to construct conduits and maintain an embrace, akin to this very piazza, in its capacity for reception."

Vance posited the papacy transcends the ephemeral realms of politics and social media. He elaborated in conversation with conservative commentator Hugh Hewitt, observing the inherent difficulty in accommodating a bimillennial institution within the exigencies of contemporary American political discourse and suggesting the collective welfare is better served by permitting the church's focus to remain primarily on the salvation of souls.

The concurrent ascensions of Trump and Leo epitomise, as Steven Millies, director of The Bernardin Center at Catholic Theological Union in Chicago, posits, the juncture where "the gospel meets the culture," a misalignment he attributes to their divergent teleological orientations.

"Both Francis and, subsequently, Cardinal Prevost, were fundamentally embodying their episcopal roles — promulgating the Gospel and underscoring its perpetual alignment with the indigent, the afflicted, and the suffering," explicated Millies via electronic mail. "This purview lies entirely outside Trump's accustomed domains as a head of state, a reality television personality, or a corporate titan."

To what extent does Pope Leo's Weltanschauung reflect American sensibilities?

Scholars posit that Leo's manifold decades residing in Peru, holding concurrent citizenship, endow him with a synoptic perspective on the complex interplay of humanity, power, religion, and politics.

Beyond the ostensible temperamental disparities with Trump, Leo is anticipated to exercise authority through divergent methodologies — prioritizing the most disenfranchised segments of the population, for instance, in stark contrast to Trump's truncation of American philanthropic initiatives. Leo, in his inaugural address, conspicuously omitted any reference to his American antecedents, and furthermore, abstained from employing the English language — an omission interpreted by certain Vatican observers as a tacit affirmation of his transnational strategic orientation.

Raul Zegarra, assistant professor of Roman Catholic theological studies at Harvard Divinity School, contended that whilst acknowledging the factual veracity of Leo being the inaugural pontiff of U.S. nativity, a more apposite conceptualisation positions him as the second pontiff originating from the Americas, a perspective which contests "America first" paradigms and fosters a more integrated regional understanding, akin to that pioneered by Pope Francis, wherein the locus of influence resides in the global south.

“This confluence of factors underscores a pontiff whose conception of global stewardship is predicated on discourse over insularity; a leader who apprehends authority not through subjugation, but through ministration,” he averred. “One would be hard-pressed to conceive of a more pronounced antithesis to the prevailing American executive.”

By the accounts of certain American cardinals, Leo's style and perspective diverge significantly from typical American sensibilities, suggesting his U.S. background held scant, if any, sway in his elevation to the papacy; nevertheless, Trump's presence cast a long shadow over the conclave.

At a press conference, six American cardinals, recently returned from the conclave, took the stage to a sonic backdrop of “Born in the USA” and “American Pie,” subsequently proceeding, in turn, to attenuate Leo’s perceived American provenance, with one quoting the circulating epigram that Leo is “the least American of the American” cardinals and several others positing him as a prospective “bridge-builder” — etymologically resonant with the Latin term “pontiff” — in relation to the Trump administration.

Queried whether the cardinals had elected Leo as a counterpoise to Trump, several demurred.

Cardinal Timothy Dolan, the Archbishop of New York, posited that his fellow cardinals would scarcely have conceived of the individual in question as a counterbalance to any singular figure.

"The cardinals, naturally, were cognisant of developments in the United States, including pronouncements and policy initiatives," stated Wilton Gregory, archbishop emeritus of Washington. Yet, the conclave's objective, he maintained, was to discern "which of our number" possessed the capacity to fortify the faith.

Millies averred, “The global community should not apprehend a pontiff of U.S. provenance; contrariwise, as arguably ‘the least American of the Americans,’ his detachment from our recent political vicissitudes renders him a seemingly innocuous figure, even whilst retaining an intrinsic American identity deeply acquainted with this nation’s more commendable attributes.”
