Magisterium

Magisterium AI's Saints database holds more than 12,500 saints, blessed, venerables, and servants of God. You can ask about a single saint, search by feast day, patronage, or era, or compare canonical statuses — all from inside chat.

What is in the Saints database

Identity: primary name, religious name, given/family names, Latin form, alternates, and the meaning of the name where known.
Status: type of saint (Saint, Blessed, Venerable, Servant of God), martyrdom, Doctor of the Church, Father of the Church, and the dates and reigning pontiff for beatification and canonization.
Life: era, vocation (religious sister, lay person, priest, bishop, founder, missionary, etc.), birth and death dates, birthplace, place of death, and religious order or congregation.
Devotion: feast day, principal patronages, iconographic attributes, and notable shrines.
Cross-references: Wikidata identifiers and "learn more" links to authoritative biographies, when available.

Asking about a saint

Use the name you know. The AI resolves common spellings, religious names, and titles into the canonical record.

Tell me about Saint Thérèse of Lisieux.
Who is Padre Pio?
Show me a profile of Blessed Carlo Acutis.

The reply opens a saint profile card you can expand to see the full biographical detail. Click through to the source links to read longer biographies on outside sites.

Searching by feast day, patronage, or status

Saints are also queryable by attribute — not just by name.

Which saints have their feast day on October 1?
List the Doctors of the Church in chronological order of canonization.
Show me canonized martyrs of the 20th century from religious orders, with their order and country of death.
Who are the patron saints of Spain?
How many Servants of God are currently in our database, broken down by century of death?

Disambiguating common names

Many names — Mary, John, Joseph, Teresa — belong to dozens of distinct saints. If you ask about "Saint Teresa" without context, the AI will list the closest matches (Avila, Lisieux, Calcutta, of the Andes, Benedicta of the Cross…) and ask which one you mean. To skip the disambiguation, include a hint: the century, the religious order, or the country.

The four databases behind Spiritual Statistics

Magisterium AI ships with four distinct Catholic datasets. The chat picks the right one (or combines several) based on your question — you do not need to specify which to use.

Catholic statistics on countries and dioceses — the Vatican Statistical Yearbook (Annuarium Statisticum Ecclesiae) and Annuario Pontificio. 51 annual snapshots from 1973–2023, covering ~235 countries and ~2,800 ecclesiastical jurisdictions worldwide.
Saints database — over 12,500 saints, blessed, venerables, and servants of God with biographical detail, canonization status, feast days, and patronages.
Ecclesiastical Directory — popes, living and historical bishops, cardinals, religious orders, basilicas, cathedrals, shrines, conclaves, consistories, ecumenical councils, apostolic nunciatures, bishops' conferences, pontifical universities, and Roman Curia departments.
Church financial records — audited financial figures for ~630 dioceses, archdioceses, eparchies, and Holy See bodies (Holy See, APSA, IOR, Bambino Gesù), including total revenue, expenses, net assets, Peter's Pence, annual appeals, and ~1,300 other metrics.

Limits and access

Free accounts can run three Spiritual Statistics queries per week and twenty data visualisations (charts) per week. Pro, Org, and Enterprise plans get unlimited Spiritual Statistics and unlimited data visualisations.

All four datasets are queried through the same chat tool. If the AI cannot find what you asked for, it will say so plainly — it does not invent figures, and every chart or profile is grounded in a row that exists in the database.
