Priorities of his teaching
Artificial intelligence and human dignity
The Pope has mentioned several times that the name "Leo" also evokes the AI challenge, just as industrialisation was in Leo XIII's time.
Migration and welcome
Son of a migrant-rooted family and bishop in Peru, he places migration as a pastoral priority. Connection with the Canary Islands visit.
Unity and ecclesial communion
His motto "In illo uno unum" expresses a pontifical programme centred on Church unity at a time of internal tensions.
Pastoral closeness and synodality
Continuity with Pope Francis's synodal line: a listening Church, a Church on the way, real decentralisation.
Relevant quotes
« Peace be with all of you. Thank you, dear brothers, for this gathering. The peace of the risen Christ, an unarmed and disarming peace, humble and persevering. »
« I have chosen the name Leo because Pope Leo XIII, with the historic encyclical Rerum Novarum, addressed the social question in the context of the first great industrial revolution. Today the Church offers to all her heritage of social doctrine to respond to another industrial revolution: that of artificial intelligence. »

Social doctrine and inequality — Continuity of Rerum Novarum adapted to the 21st century.
The central axis of his pontificate. In his first address to the College of Cardinals he explained that he chose the name Leo to link the 19th-century social question with today's challenges: job insecurity, rich-poor gap, concentrated technology.

Artificial intelligence — Second industrial revolution demanding Church response.
Leo XIV has made AI a priority of his magisterium. He calls for international regulation guaranteeing human dignity against labour displacement and algorithmic manipulation, and a Church that does not shy away from technology debates.

Migration — Welcome as pastoral priority tied to his biography.
Son of a migrant-rooted family and bishop in Peru for more than three decades, he has placed migration as an ethical test of the century. He insists that no wall is higher than human dignity and criticises the political instrumentalisation of migration.

Pro-life and dignity of the person — Unwavering defence of life from conception to natural death.
Classic firm Church position, with no opening to abortion. He extends the approach to the death penalty, euthanasia and undignified living conditions (poverty, war, trafficking). He has stressed that "pro-life" means defending all life, not just prenatal.

LGBT people and synodality — Pastoral welcome within traditional teaching.
Continues the line of "Fiducia supplicans" of Pope Francis (blessings for people in irregular relationships, without equating to sacramental marriage). Advocates listening and welcoming pastoral care, without altering the doctrine on the sacrament of marriage.
Source: Intervención sinodal, octubre 2024
Traditional Mass (Latin rite) — Ecclesial communion above ritual form.
He has remained prudent on Traditionis custodes. Recognises the value of the extraordinary rite for those who live it in ecclesial communion, but discourages its use as an identity banner. Prioritises Church unity over liturgical dispute.

Female ordination to the diaconate — Question open to synodal discernment.
Does not close the door to the study of female diaconate (as Francis did not), but insists that it is an ecclesial discernment, not an ideological demand. Maintains the reservation of the ministerial priesthood to men.

Peace and war — Unarmed and disarming peace, active diplomacy.
From his first words at the Vatican Loggia he mentioned "unarmed and disarming peace". Continues Francis's magisterium on Ukraine, Gaza, Sudan and other crises, denouncing the arms race and the use of autonomous weapons.
