Pope Leo XIV: Dilexi Te Part E - Pre-Conciliar Teachings

 +

JMJ



In reading the chatGPT outputs, I noticed that, while citing the Father’s and earlier writings of the Church, earlier Church Councils etc are absent.

So I created a new prompt to investigate what the LLM (i.e. chatGPT) would produce.

Prompt

Looking at the pre 1960 documents of the Catholic Church, which ones included the care and love of the poor?

Result

That’s an excellent question — and a deeply revealing one. Long before 1960, the Catholic Church had already developed a strong tradition of teaching on the care and love of the poor, rooted in Scripture, the Fathers of the Church, and later formalized in social encyclicals and other magisterial texts.

Here’s a structured overview of key pre-1960 Church documents that explicitly emphasize love for and care of the poor, the vulnerable, and the working classes.


1. Rerum Novarum (1891) – Pope Leo XIII

Theme: The rights and duties of capital and labor.

Core message:

This encyclical is the foundation of modern Catholic social teaching. Leo XIII condemned both unrestrained capitalism and socialism, affirming the dignity of labor, the right to private property, and—centrally—the Church’s duty to protect and uplift the poor.

> “The rich must religiously refrain from cutting down the workman’s earnings, whether by force, by fraud, or by usurious dealing; and with all the greater reason because the poor man’s earnings are sacred.”

> — Rerum Novarum, §20

2. Quadragesimo Anno (1931) – Pope Pius XI

Theme: Reconstruction of the social order (issued 40 years after Rerum Novarum).

Core message:

Pius XI expanded Leo XIII’s teaching, calling for the reform of unjust economic systems and emphasizing solidarity with the poor. He highlighted subsidiarity—that social assistance should be provided at the lowest possible level while protecting the vulnerable.

> “Every effort must therefore be made that the poor and the workers be drawn closer to those who are rich.”

> — Quadragesimo Anno, §60

3. Mater et Magistra (1961) – Pope John XXIII

(Technically post-1960, but conceived in continuity with earlier documents.)

Theme: Christianity and social progress.

Core message:

John XXIII reaffirmed and updated Leo XIII and Pius XI, stressing that social development and economic justice are acts of love toward the poor.

> “The duty of every man is to consider his neighbor’s needs and rights as closely as his own.”

> — Mater et Magistra, §30

4. Summi Pontificatus (1939) – Pope Pius XII

Theme: The unity of human society.

Core message:

Issued at the start of World War II, this encyclical spoke of the moral obligation to uphold human dignity and aid those suffering from oppression, poverty, and war.

> “The nations of the earth are called to a higher justice and charity, without which peace and order cannot be restored.”

5. Deus Caritas Est (Patristic roots and continuity)

Although Deus Caritas Est itself is from 2005 (Benedict XVI), it explicitly cites the early Church practice — from Acts 2:44-45 and the writings of the Fathers — of communal sharing and love for the poor.

Before 1960, this tradition appeared in:

The Didache (1st–2nd century): “Do not turn away from one who is in need.”

St. John Chrysostom (4th century): “The property of the rich belongs to the poor.”

St. Ambrose (4th century): “You are not making a gift of your possessions to the poor person. You are handing over to him what is his.”

These ideas strongly influenced Leo XIII’s Rerum Novarum.

6. Mystici Corporis Christi (1943) – Pope Pius XII

Theme: The Church as the Mystical Body of Christ.

Core message:

By defining the Church as Christ’s living body, Pius XII grounded the duty of care for the poor in theology: to serve the poor is to serve Christ Himself.

> “Those who are most in need of comfort and assistance are the members who are the sick, the infirm, the poor.”

7. Missionary and charitable instructions

Several papal documents and Vatican directives prior to 1960 emphasized charity as an essential expression of faith:

Benedict XIV, Vix Pervenit (1745): Condemned usury and economic exploitation of the poor.

Leo XIII, Graves de Communi Re (1901): Called for Christian democracy rooted in charity and service to the poor.

Pius XII’s wartime addresses (1939–1958): Urged Catholics to rebuild society through compassion and justice.






Pre-Modern Teaching

Then chatGPT provided the following query:

Would you like me to include pre-modern sources (e.g., medieval papal bulls or conciliar decrees) that addressed poverty and charity — such as those from Gregory the Great, Innocent III, or the Council of Trent? They add important context to how the Church’s commitment to the poor developed before the industrial age.

My response:

Yes include pre-modern source

The Result



Excellent — that deepens the picture considerably.

When we widen the lens to include pre-modern (pre-19th-century) sources, we find that the care and love of the poor is not a late development but one of the most continuous and characteristic elements of Catholic doctrine.

Below is a chronological overview of key pre-1960 sources — now including patristic, medieval, and early-modern foundations — showing how the theme of charity toward the poor evolved from Gospel roots into formal Church teaching.

I. Scriptural and Patristic Roots (1st–6th centuries)

The biblical mandate — “Whatever you did for one of the least of these brothers of mine, you did for me” (Mt 25:40) — lies at the core of all later documents.

1. The Didache (c. A.D. 100)

> “Do not turn away from him who is in need; share all things with your brother.”

> Early Christian manual prescribing almsgiving as a moral duty.

2. The Apostolic Constitutions (4th cent.)

Regulations for bishops:

> “Let the bishop care for all, especially the poor, the widows, and the orphans.”

3. Church Fathers

St. Basil the Great, Homily to the Rich (4th cent.): “The bread you keep belongs to the hungry.”

St. John Chrysostom: “Not to share our wealth with the poor is to steal from them.”

St. Ambrose: Linked almsgiving with justice, not optional mercy.

St. Augustine: Developed the theology of the common use of goods (usus communis).

These Fathers shaped all subsequent papal and conciliar reflection on poverty and property.

🏛️ II. Early Medieval Teaching (6th–11th centuries)

4. Pope Gregory the Great, Regula Pastoralis (c. 590 A.D.)

Pastoral guide emphasizing bishops’ duty to use Church property for the poor:

> “Let him regard the riches of the Church as the patrimony of the poor.”

5. Monastic Rules

Rule of St. Benedict (6th cent.) ordered hospitality and almsgiving as expressions of humility and communal charity.

These rules institutionalized care of the poor in monasteries across Europe.

III. High and Late Middle Ages (12th–15th centuries)

6. Fourth Lateran Council (1215) – Innocent III

Mandated clerics to live modestly and use ecclesiastical revenues for the needy.

Canon 25: bishops must ensure support for the poor from cathedral funds.

7. Papal Bulls on Charity and the Poor

Innocent III, Cum inter nonnullos (1213): urged bishops to provide hospitals and hospices.

Gregory IX, Quo elongati (1230): confirmed Franciscan poverty ideal.

Nicholas III, Exiit qui seminat (1279): clarified that Franciscan renunciation served evangelical witness to the poor.

8. Scholastic Theology

St. Thomas Aquinas, Summa Theologiae II-II q. 32–66:

Almsgiving is a work of justice as well as mercy.

The poor have a right of necessity to what is superfluous to the rich.

These principles became the backbone of later social encyclicals.

IV. Early-Modern Era (16th–18th centuries)

9. Council of Trent (1545–1563)

Reaffirmed corporal works of mercy and required bishops to found seminaries and hospices; charity seen as essential to pastoral life.

Decree on Reformation (Sess. XXII, c. 1): Church revenues are to aid the poor before any luxury.

10. Papal and Post-Tridentine Actions

St. Pius V (1566–1572): enforced poor relief and hospital visitation by clergy.

Urban VIII, In eminenti (1622): supported missionary congregations providing education and care to the destitute.

Benedict XIV, Vix Pervenit (1745): condemned usury as exploitation of the poor — a decisive economic application of charity.

V. Nineteenth-Century Transition to Modern Social Teaching

11. Gregory XVI, Mirari Vos (1832) and Singulari Nos (1834)

While primarily doctrinal, they defended Christian charity as the moral counterweight to revolutionary violence.

12. Pius IX, Qui pluribus (1846) and Syllabus Errorum (1864)

Condemned materialism and indifferentism that ignored the poor; foreshadowed a social response later articulated by Leo XIII.



Progression of Church’s Teaching

As is usual chatGPT provided me with a next step:

Would you like me to present this as a **timeline or chart (2–3 pages)** showing how the Church’s teaching on the poor developed from *Acts of the Apostles* to *Mater et Magistra*? It would clearly trace the doctrinal continuity and main turning points.

The result

News Roundup: July 11, 2025

 + JMJ This has been an interesting month for news ... First we had the leaking of the 2021 report on what I would call the "Survey of Tradition".  Not surprisingly, the report was generally positive and Pope Francis ... for whatever reason ... still proceeded with Traditionis Custodes.  Andrea Grillo is not pleased with this turn of affairs. I suspect that the 'leaking' of the report is a symptom of a course correction.  Time will tell as this pontificate unfolds.  I am still curious to hear if the SSPX Superiour General will be invited to Rome this summer while the Pope reclaims the Castel Gandolfo.   That is my critical success indicator for whether or not Catholics can really consider the pontificate of Pope Francis (RIP) are truly an aberration of the past. Then we have the firing of John-Henry Westen from Life Site News.  I have no idea what happened to cause the board coup - - - as close a the vote was - he is now out of LFN.  There is...

News Roundup: May 13, 2026

 + JMJ Introduction I have set this article to post on May 13th, the anniversary of the first of six apparitions of the Blessed Virgin Mary at Fatima. Fatima while a historical fact, still seems to point to the future.  Has the consecration been done according to her wishes?  Will another Pope do it again in the face of a world going mad and slipping into the same conditions that fostered two great wars? I don't know.  But I pray that the message of Fatima to repent and do penance is heard in the hearts of Catholics every where.  We carry the light to the world and need to illuminate the 'The Way'. The Catholic Church Obviously, the death of Pope Francis I and the election of Pope Leo XIV is a major development in the Catholic Church and the World. Just what the immediate outcomes of these two events will take some time.  I strongly suspect that there will be no calls of Santo Subito for Pope Francis.  If there is and if they do canonize Pope Francis ....

Rome,the SSPX and this time of Crisis - Updated

+ JMJ Obviously there's lots of events right now. First we have the April 1st - I almost thought it was April Fools - meeting between Pope Francis and Bishop Fellay.  Nothing really news worthy as this is a natural progression as Rome appears to be considering fulfilling Archbishop Lefebvre's wish to 'accept us as we are'. Second we have the April 8th publication of what will be a verbose exhortation of the Synod of the Family. I'm willing to bet that the Pope will give with one hand (unilateral regularization of SSPX) and take with the other (ambiguous document that opens the flood gates of sin further). Much to pray for.
