Magisterium
- Magnifica Humanitas Encyclical
Leo XIV’s encyclical on artificial intelligence and the social doctrine of the Church. Framed by two biblical images of collective building — the Tower of Babel and Nehemiah’s rebuilding of Jerusalem — it argues that AI is not one more subject for social doctrine to address but a development that challenges its categories from within, and takes up human dignity and the common good, truth, work and freedom, and the growing place of autonomous systems in war.
- Una Caro CDF Doctrinal Note
A doctrinal note on monogamy, addressed chiefly to the bishops and prompted by their ad limina conversations about polygamy and by the spread of “polyamory” in the West. Setting indissolubility and procreation aside, it treats unity, the first essential property of marriage, through Scripture, the Fathers, the popes from Leo XIII to Leo XIV, philosophy and poetry, and closes on mutual belonging and conjugal charity, a friendship open to others.
- Mater Populi Fidelis CDF Doctrinal Note
A doctrinal note on the Marian titles that bear on Mary’s cooperation in salvation, answering requests that had reached the Holy See over decades. It judges it inappropriate to use “Co-redemptrix” to define that cooperation, admits “Mediatrix” only within the unique mediation of Christ, and rests the whole question on her motherhood towards believers — her intercession and maternal closeness — closing with Mother of the Faithful People of God.
- Dilexi Te Apostolic Exhortation
Leo XIV’s first apostolic exhortation, completing a text Francis left unfinished at his death, on the Church’s love for the poor. It traces the biblical ground of God’s preferential care for them, gathers the patristic and monastic witnesses, reviews the social doctrine from Rerum Novarum onward, and closes on the Good Samaritan with an appeal to renew almsgiving and confront the structures that produce poverty.
- Outline for the Examination of Conscience Outline
- Antiqua et Nova CDF Doctrinal Note
On the relationship between artificial intelligence and human intelligence, weighing the Christian understanding of intelligence — reason, embodiment, relationship, truth, stewardship of creation — against what AI can only imitate. It surveys AI’s ethical stakes for society, work, healthcare, education, misinformation, privacy, and warfare, warns against treating AI as a substitute for God, and closes with an appeal to a “wisdom of the heart” no machine can supply.
- Dilexit Nos Encyclical
Francis’s 2024 encyclical on devotion to the Sacred Heart of Jesus: what the symbol of the “heart” can still mean for a distracted age, what Christ’s own gaze, words and pierced side reveal about his human and divine love, the history of this devotion from Margaret Mary through Francis de Sales, Claude de la Colombière, Charles de Foucauld and Thérèse of Lisieux, and how reparation for love unreturned extends into fraternity, mission and social concern.
- The Queen of Peace: Note on the Spiritual Experience Connected with Medjugorje CDF Doctrinal Note
The note closing the Medjugorje question under the 2024 Norms with a Nihil obstat — which authorizes public acts of devotion without asserting the supernatural authenticity of the phenomenon, and judges nothing about the visionaries’ moral life. It surveys the fruits and the themes of the messages, from the Queen of Peace to conversion, prayer and the centrality of the Mass, then flags the reprimands, threats and self-exaltation found in some of them.
- Press Release about Alleged Apparitions in Amsterdam CDF Communication
A press release publishing for the first time the decision the Congregation reached on 27 March 1974 about the apparitions and revelations alleged at Amsterdam between 1945 and 1959, and the devotion to “The Lady of All Nations”: on the doctrinal judgment, unanimously constat de non supernaturalitate, and against investigating the phenomenon further. Paul VI approved it on 5 April 1974; it is made known now because doubts persisted.
- Norms for Proceeding in the Discernment of Alleged Supernatural Phenomena CDF Norms
The 2024 norms, which entirely replace those of 1978. Discernment normally no longer ends in a declaration of supernatural character but in one of six graded conclusions — Nihil obstat, Prae oculis habeatur, Curatur, Sub mandato, Prohibetur et obstruatur, Declaratio de non supernaturalitate. The diocesan bishop keeps watch afterwards, applies penal law where deception for gain is proven, and the Dicastery may intervene motu proprio at any stage.
- Spes Non Confundit Bull
Francis’s 2024 bull of indiction proclaiming the Ordinary Jubilee of 2025, opening from Paul’s “hope does not disappoint” and fixing the dates the four papal basilicas’ Holy Doors open and close. It urges concrete “signs of hope” — peace, openness to life, clemency for prisoners, care for the sick, the young, migrants and the poor — before anchoring hope in the resurrection, the Jubilee indulgence and Mary, Mother of Hope.
- Dignitas Infinita CDF Declaration
On human dignity, distinguishing ontological, moral, social, and existential senses of the term and grounding an inviolable, infinite dignity in every person’s creation in God’s image and redemption in Christ. Tracing this conviction from Scripture through Christian thought, the declaration then names concrete violations: poverty, war, the plight of migrants, human trafficking, sexual abuse, violence against women, abortion, surrogacy, euthanasia, disability, gender theory, sex change, and digital violence.
- Fiducia Supplicans CDF Declaration
A declaration on the pastoral meaning of blessings, holding firm the doctrine of marriage — no liturgical rite, and nothing resembling one, that could create confusion — while broadening the classical understanding of a blessing beyond the liturgical. Within that horizon it admits blessings for couples in irregular situations and for couples of the same sex: spontaneous, unfixed in form, claiming no legitimation of their state but begging God’s help.
- C’est la confiance Apostolic Exhortation
On Saint Thérèse of Lisieux and her “little way” of confidence, written for the 150th anniversary of her birth. Reading her own writings, Francis traces how she found holiness not through her merit but through trusting abandonment to God’s mercy, and proposes her vocation — to be love in the heart of the Church — and her hidden missionary zeal as an answer to a self-absorbed age.
- Laudate Deum Apostolic Exhortation
Francis’s follow-up to Laudato Si’, addressed to all people of good will on the climate crisis eight years on. It reviews the scientific evidence for global warming, criticizes the technocratic paradigm that treats unlimited technological power as good in itself, faults the weakness of multilateral climate diplomacy up to COP28 in Dubai, and closes with the spiritual motivations for caring for creation.
- Praedicate Evangelium Apostolic Constitution
Francis’s 2022 constitution reorganizing the Roman Curia, replacing John Paul II’s 1988 Pastor Bonus. Grounding the reform in the Church’s “missionary conversion” — every Christian a missionary disciple — it sets twelve governing principles, among them co-responsibility and the Curia’s vicarious nature, then regulates in 250 articles the Secretariat of State and the Dicasteries, led by the Dicastery for Evangelization, placed first and presided over directly by the Pope.
- Norms on Delicts Reserved to the Congregation for the Doctrine of the Faith CDF Norms
The 2021 recension of the norms on delicts reserved to this Congregation. Part one names them: heresy, apostasy and schism; the graver delicts against the Eucharist and against Penance, the violation of the seal among them; the attempted ordination of a woman; and, against morals, a cleric’s sin with a minor under eighteen and clerical possession or distribution of child pornography. Part two governs the tribunal, the judicial and extrajudicial processes, and the pontifical secret.
- Traditionis Custodes Motu Proprio
Francis’s 2021 motu proprio on the use of the Roman liturgy prior to the 1970 reform, declaring the liturgical books of Paul VI and John Paul II the Roman Rite’s sole lex orandi and placing the 1962 Missal under each diocesan bishop’s exclusive authority. Existing groups must accept the reform’s legitimacy, gather away from parish churches under a delegated priest, and see no new groups established.
- Fratelli Tutti Encyclical
On fraternity and social friendship, opening from St Francis of Assisi’s love that crossed every border. It surveys a closed and throwaway world of nationalism and fear, reads the Good Samaritan as the call to an open society built on solidarity and the rights of peoples, and argues for a political charity against populism, for dialogue and forgiveness after conflict, against war and the death penalty, and for fraternity between religions.
- Samaritanus Bonus CDF Letter
On the pastoral and medical care of persons in the critical and terminal stages of life, read through the Good Samaritan’s care for the wounded man. It excludes euthanasia and assisted suicide as morally impermissible, requires basic nutrition and hydration and access to palliative care, and addresses pastoral and sacramental accompaniment, healthcare workers’ conscientious objection, and the reform of medical formation.
- Querida Amazonia Apostolic Exhortation
Francis’s post-synodal reflection on the Amazon, built around four dreams for the region: social, cultural, ecological and ecclesial. He denounces the exploitation of indigenous peoples and the poor by mining and timber interests, calls for evangelization, liturgy and priestly formation inculturated in Amazonian ways, praises the women who have long sustained the faith where no priest reaches, and closes with a prayer to Mary.
- Christus Vivit Apostolic Exhortation
Francis’s 2019 post-synodal exhortation addressed to young people and to the whole People of God, gathering the fruit of the Synod on Young People. It reads Scripture and Jesus’s own youth as speaking directly to them, surveys their situation today — digital culture, migration, abuse — then turns to vocation, friendship with Christ, intergenerational roots, youth ministry and discernment.
- Letter to the Bishops Regarding the New Revision of Number 2267 of the Catechism of the Catholic Church on the Death Penalty CDF Letter
The letter to the bishops accompanying the 2018 rewriting of Catechism 2267, arguing that the new text develops doctrine rather than contradicting the Magisterium before it. It traces the change through Evangelium vitae and the appeals of John Paul II, Benedict XVI and Francis, and rests it on a dignity no crime removes, penalties ordered to rehabilitation, and detention that makes execution unnecessary.
- Gaudete Et Exsultate Apostolic Exhortation
Francis’s exhortation on the universal call to holiness, insisting it belongs not to the canonized but to “the saints next door” living ordinary life with love. It diagnoses two heresies that distort it, gnosticism and pelagianism, reads holiness through the Beatitudes and Matthew 25, names five everyday signs of it, and closes on spiritual combat, vigilance and discernment.
- Placuit Deo CDF Letter
A 2018 letter to the bishops from the Congregation for the Doctrine of the Faith, warning against two contemporary distortions of Christian salvation: a neo-Pelagian individualism that trusts self-realization by one’s own strength, and a neo-Gnostic disregard for the body that reduces salvation to a merely interior experience. Against both, it presents Christ as Savior and the Church, through her sacraments, as the visible communion in which salvation is received.
- Oeconomicae et Pecuniariae Quaestiones CDF Considerations
Considerations issued jointly by the Congregation for the Doctrine of the Faith and the Dicastery for Promoting Integral Human Development on the ethics of the global financial system, moving from principles of market freedom and regulation to concrete instruments — derivatives, LIBOR-set interbank rates, shadow banking, and offshore tax havens — before closing with an appeal to personal and associative responsibility over cynicism.
- Veritatis Gaudium Apostolic Constitution
Reforms the governance, curricula and degrees of Ecclesiastical Universities and Faculties worldwide, renewing the 1979 Sapientia Christiana. Its Foreword sets four criteria for the renewal of ecclesiastical studies — the kerygma, dialogue, interdisciplinarity, and networking among institutions — before general norms on government, teachers, students and degrees, then special norms for the faculties of theology, canon law and philosophy. An appendix carries Sapientia Christiana’s own foreword and the implementing Norms of Application.
- Magnum Principium Motu Proprio
Amends canon 838 of the Code of Canon Law, governing translation and approval of liturgical books into vernacular languages. Recalling the Council’s principle that liturgical prayer be understood by the people, it assigns the Apostolic See to order the liturgy and recognise adaptations, the Episcopal Conferences to prepare and publish vernacular versions after the Apostolic See’s confirmation, and the diocesan bishop to set liturgical norms within his own church.
- Maiorem Hac Dilectionem Motu Proprio
Francis’s 2017 motu proprio establishing the offer of life — the free, voluntary sacrifice of one’s life out of love, followed swiftly by death — as a new cause for beatification, distinct from martyrdom and heroic virtue. Article 2 sets its five criteria, including a link between the offer and premature death and a posthumous miracle; the closing articles amend the Congregation for the Causes of Saints’ procedural norms to accommodate it.
- Ad Resurgendum cum Christo CDF Instruction
The Congregation for the Doctrine of the Faith’s 2016 Instruction on Christian burial and cremation, approved by Francis. It reaffirms the Church’s preference for burying the faithful departed in cemeteries or sacred places as an expression of hope in the resurrection, permits cremation where doctrinally sound, and sets norms requiring the ashes to remain intact in a sacred place — forbidding their conservation at home, scattering, or division among mementos.
- Iuvenescit Ecclesia CDF Letter
A letter to the bishops on the relationship between the hierarchical and the charismatic gifts, written as movements and new communities multiplied. Both come from the same Spirit and are co-essential to the Church’s constitution, so neither runs parallel to the other. It gives criteria for discerning an authentic charism, and asks that juridical recognition fit a group rather than deaden what is new in it.
- Amoris Laetitia Apostolic Exhortation
- Mitis Et Misericors Iesus Motu Proprio
Francis’s 2015 motu proprio reforming the Code of Canons of the Eastern Churches’ marriage-nullity procedure, canons 1357 to 1377, issued separately given those Churches’ own disciplinary structure. It drops the second conforming sentence, makes the eparchial bishop himself first-instance judge, and adds a briefer process he alone conducts for manifest nullity, while keeping appeal to the Metropolitan and the Roman Rota. An attached ratio procedendi adds pastoral investigation before the libellus.
- Mitis Iudex Dominus Iesus Motu Proprio
Reforms the Code of Canon Law’s marriage-nullity trial, canons 1671 to 1691: a single first-instance declaration of nullity now suffices, without the second conforming sentence required before; ordinary judgment is entrusted to a sole cleric judge appointed by the bishop; manifest cases may go to the bishop himself through a new briefer process; and appeal returns to the metropolitan see. Attached procedural rules open with pastoral outreach to separated and divorced spouses.
- Laudato si’ Encyclical
Francis’s encyclical on ecology, taking its title from Saint Francis’s Canticle of the Creatures. It diagnoses pollution, climate change, water scarcity, biodiversity loss and social breakdown as symptoms of one crisis rooted in a “technocratic paradigm,” develops an “integral ecology” linking care for nature to justice for the poor, and proposes lines of dialogue, education, and “ecological conversion.”
- Misericordiae Vultus Bull
Francis’s 2015 bull proclaiming the Extraordinary Jubilee of Mercy, opening 8 December — the anniversary of Vatican II’s close — and closing 20 November 2016, under the motto “Merciful like the Father.” It traces mercy through Scripture and the Gospel parables, recalls the corporal and spiritual works of mercy, sends out Missionaries of Mercy to absolve reserved sins, and entrusts the Holy Year to the Mother of Mercy.
- Evangelii Gaudium Apostolic Exhortation
Francis’s programmatic exhortation launching his pontificate, calling the whole Church to a joy-filled missionary conversion. It diagnoses an “economy of exclusion” and the temptations of spiritual worldliness among pastoral workers, sets out how to prepare a homily and deepen catechesis, argues that evangelization carries an inescapable social dimension toward the poor and the common good, and closes by invoking Mary as Star of the new evangelization.
- Lumen Fidei Encyclical
On faith as the light of Christ by which human life is guided — the encyclical that completes the trilogy on the theological virtues, drafted by Benedict XVI before his resignation and finished by Francis. It follows faith from Abraham and Israel to Christ, examines its bond with truth and with reason, its transmission through the Church’s creed and sacraments, and its power to sustain the family, society and those who suffer.
- Ecclesia In Medio Oriente Apostolic Exhortation
Benedict XVI’s post-synodal exhortation following the 2010 Special Assembly of the Synod of Bishops for the Middle East, on that region’s Church living out communion and witness. It treats ecclesial communion, ecumenism and dialogue with Jews and Muslims amid emigration; then patriarchs, clergy, religious, laity, families and youth; then witness through Scripture, liturgy and catechesis, closing with an appeal to regional authorities for peace.
- Preface to the Norms on Presumed Apparitions and Revelations CDF Communication
The preface accompanying the first official publication of the 1978 Normae on judging presumed apparitions and revelations, which Paul VI approved but which went to bishops unpublished and had since circulated without permission. It sets them in the frame Benedict XVI gave in Verbum Domini: a private revelation does not complete Christ’s definitive revelation but helps one live by it, and is judged by whether it orients the reader to him.
- Africae Munus Apostolic Exhortation
Benedict XVI’s post-synodal exhortation drawing on the 2009 Synod for Africa, addressed to the Church in Africa as salt of the earth and light of the world. It treats reconciliation, justice and peace across family, culture, governance, creation and interreligious dialogue, then the Church’s own members from bishops to laity, and her apostolate in education, health care, media and the sacraments.
- Circular Letter to Assist Episcopal Conferences in Developing Guidelines for Dealing with Cases of Sexual Abuse of Minors CDF Letter
A circular letter telling every episcopal conference to draw up guidelines on the sexual abuse of minors by clerics. It puts the victims first — listening, spiritual and psychological help, safe-environment programmes — then sets what the guidelines must contain: the diocesan bishop’s own responsibility and potestas regiminis, respect for privacy and the accused’s right to answer, allowance for the country’s law on notifying civil authorities, and no return to ministry that endangers minors.
- Note on the Banalization of Sexuality CDF Doctrinal Note
A note correcting readings of Benedict XVI’s interview-book Light of the World that took his remarks for a change in the teaching on contraception. His words concern prostitution, not conjugal morality, and license nothing. That someone with HIV uses a condom to reduce the risk to another may be a first step towards a more human sexuality, while the act stays gravely disordered — which is not the theory of the lesser evil.
- Verbum Domini Apostolic Exhortation
Benedict XVI’s post-synodal exhortation on the Word of God, gathering the 2008 Synod of Bishops into three parts: the theology of divine revelation and its interpretation in the Church, the word’s place in liturgy, catechesis and consecrated life, and the Church’s mission to proclaim it to the world through culture, social commitment and interreligious dialogue.
- Complementary Norms for the Apostolic Constitution Anglicanorum Coetibus CDF Norms
Fourteen articles giving practical shape to the apostolic constitution Anglicanorum Coetibus. Each personal ordinariate for former Anglicans answers to this Congregation; its Ordinary, a bishop or presbyter appointed from a terna, sits in the national episcopal conference, incardinates former Anglican ministers, and governs with a Governing Council half elected by his priests and a Pastoral Council. The last article provides for personal parishes and quasi-parishes.
- Clarification on Procured Abortion CDF Communication
Issued in answer to letters received by the Congregation, and built almost wholly of citations: the Catechism on human life from the moment of conception and on the latae sententiae excommunication attached to formal cooperation in abortion, Donum Vitae on the law’s duty to protect the unborn, and Evangelium Vitae 62. It closes by distinguishing “therapeutic” abortion, never licit, from a procedure whose unintended effect is the child’s death.
- Caritas In Veritate Encyclical
On integral human development in charity and truth, taking up Paul VI’s Populorum Progressio forty years on. Charity in truth is set out as the principle of the Church’s social doctrine and then applied: to the global financial crisis, to the ethics of business and the market, to gratuitousness and gift, to the environment, to cooperation between peoples, and to the human meaning of technology and bioethics.
- Summary of the Instruction Dignitas Personae CDF Communication
The Congregation’s own summary of the instruction Dignitas Personae, section by section: its aim, title, doctrinal weight and recipients; then the two fundamental principles on human life and procreation; then the new questions of in vitro fertilization, ICSI, the freezing of embryos and of oocytes, embryo reduction and preimplantation diagnosis; and finally gene therapy, cloning, stem cells, hybridization, and the use of biological material of illicit origin.
- Dignitas Personae CDF Instruction
The Congregation for the Doctrine of the Faith’s instruction extends Donum vitae to techniques developed in the twenty years since, addressing in vitro fertilization, embryo freezing, preimplantation diagnosis, gene therapy, human cloning, stem-cell research, and the use of biological material of illicit origin, judging each by whether it respects the dignity, unity, and identity of the human person from conception.
- Responses to Questions Proposed on the Validity of Baptism CDF Responsum
Two responses on the form of baptism: whether baptism conferred with the formulas “I baptize you in the name of the Creator, and of the Redeemer, and of the Sanctifier” and “of the Creator, and of the Liberator, and of the Sustainer” is valid — negative — and whether those baptized with them must be baptized in forma absoluta — affirmative. Approved by Benedict XVI, 1 February 2008.
