At 171B Cống Quỳnh Street, along a tightly packed urban block, stands a building that passersby could easily mistake for a regular residence. There are no twin bell and drum towers, no three-tiered curved roofs, and no ceremonial forecourt. Inside, however, is Thiên Nhãn (the Divine Eye), the familiar emblem of Caodaism, and members still gather here for the four daily services.
This is Cơ Quan Phổ Thông Giáo Lý Đại Đạo (the Cao Đài Institute for Religious Studies and Propagation). The library includes this address under Places not because it is a grand sanctuary, but because it represents a rare kind of institution where members of different Cao Đài churches work together on a single shared task, studying and writing religious doctrine. To read this place properly, one must first set aside the template of a parish temple.
IA doctrinal institute, not a separate sect
From its early decades Caodaism branched into multiple churches (Hội Thánh), each with its own Holy See, clerical hierarchy, and network of local temples. Alongside them exist esoteric lineages (pháp môn), paths of inner cultivation that do not form ecclesiastical bodies. Cơ Quan Phổ Thông Giáo Lý Đại Đạo belongs to neither category.
The most common misconception about this place is calling it a Cao Đài sect (chi phái) or a local temple (thánh thất). Both labels miss its nature entirely.
Official rosters of Cao Đài churches and religious organizations do not list Cơ Quan Phổ Thông Giáo Lý Đại Đạo as a church, and that omission accurately reflects its character. The institute has no lay congregation of its own, no separate clerical hierarchy modeled on a church, no subordinate local temples in the provinces, and does not initiate converts into a private roll. Nor is it a local temple, because a thánh thất serves a territorial parish whereas this institute has no parish. Its work is to research and propagate the shared doctrine of Caodaism, taking upon itself the role of a fraternal bridge among the churches without belonging exclusively to any single one.
| Category | Characteristics | Example |
|---|---|---|
| Hội Thánh (Church) | Has a Holy See as its central seat, a clerical hierarchy, a network of temples, and its own lay membership | Tây Ninh Cao Đài Church, Chiếu Minh Long Châu Cao Đài Church |
| Thánh thất (local temple) | The house of worship and liturgical center of a local parish under a church | Đô Thành Cao Đài Temple on Trần Hưng Đạo Street |
| Pháp môn (meditative lineage) | A path of esoteric cultivation that does not form a church or ordain administrative clergy | Chiếu Minh Tam Thanh Vô Vi lineage |
| Doctrinal institute | Has no private lay membership or subordinate temples, focusing on shared doctrinal research and teaching | Cơ Quan Phổ Thông Giáo Lý Đại Đạo |
The motto of the institute comprises three aims that each begin with the word phổ (universal or widespread), namely phổ truyền chánh pháp (universally transmitting the true dharma), phổ biến giáo lý (widely disseminating doctrine), and phổ tế quần sanh (universally aiding living beings). The first preserves the faithful transmission of the teachings, the second brings doctrine to readers through books and study courses, and the third offers charitable aid without regard to church affiliation.
In its worship, the institute follows the shared canon of Caodaism. The supreme being venerated here is Đức Chí Tôn, represented by Thiên Nhãn (the Divine Eye) rather than a carved statue, alongside an altar to Đức Phật Mẫu (the Holy Mother). The full name of the faith is Đại Đạo Tam Kỳ Phổ Độ, and its overarching principle is returning the Three Teachings to their source and uniting the Five Branches (tam giáo quy nguyên, ngũ chi phục nhất). The institute turns that very principle into its daily work, reasoning that if the great world religions share a single root, then the churches of a single faith have all the more reason to keep a place where they can sit together.
Why include such an address in a directory of places? Because throughout this Places section, readers encounter Cao Đài sanctuaries belonging to many different churches, each with its own altar arrangement and liturgical customs. A reader could easily conclude that Caodaism is merely a collection of disconnected branches. Cơ Quan Phổ Thông Giáo Lý Đại Đạo is tangible evidence to the contrary, showing where the shared foundation lies. The four Chinese characters at the top of this page are the library's rendering of the phrase Phổ Thông Giáo Lý for readers familiar with Sino-Vietnamese script rather than a transcription from a signboard at the headquarters.
IIFrom a committee to an institute
This institution has several founding dates that are easily conflated because its name, office, and headquarters building took shape at different moments. The timeline below separates those stages clearly.
- 1962Founding of the Doctrinal Propagation BoardIn the eighth lunar month of Nhâm Dần (1962), Ban Phổ Thông Giáo Lý Liên Quan Hành Đạo is formed to care for doctrinal study and teaching. This is the earliest precursor of the institute before it had a permanent home.
- 1965Opening of the first officeAt the full moon of the first lunar month of Ất Tỵ (institute records give either 16 February or 15 February 1965), the Doctrinal Propagation Office opens at 165E Cống Quỳnh Street (which institute records note is now numbered 171B). From this point the body has a fixed working address.
- 1966Standing Committee and Governing RegulationsOn 5 March 1966 (14th day of the 2nd lunar month, Bính Ngọ), the Standing Committee is formally established under the Sacred Regulations (Thánh Dụ Quy Điều), with Elder Huệ Lương Trần Văn Quế serving as the first Director General (Tổng Lý Minh Đạo) over five specialized departments (Internal Affairs, Administration, Culture, Youth, and External Relations).
- 1969First stone laid for the 171B Cống Quỳnh buildingOn 11 September 1969 (30th day of the 7th lunar month, Kỷ Dậu), a ceremony is held to lay the first stone for a new multi-story headquarters building at 171B Cống Quỳnh Street.
- 1970Completion and inauguration of the headquartersConstruction is completed on 4 February 1970 (28th day of the 12th lunar month, Kỷ Dậu), and the inauguration ceremony takes place on 22 March 1970 (full moon of the 2nd lunar month, Canh Tuất). This is the building the institute occupies to this day.
- 1981Adoption of the present nameOn 18 May 1981 (15th day of the 4th lunar month, Tân Dậu), the official name changes from Cơ Quan Phổ Thông Giáo Lý Cao Đài Giáo Việt Nam to Cơ Quan Phổ Thông Giáo Lý Đại Đạo. The term Đại Đạo (Great Way) underscores its focus on the universal doctrine of the faith.
The four years 1962, 1965, 1970, and 1981 are often used interchangeably in secondary accounts, which frequently pick one date and call it the founding year. Stated precisely, 1962 is when the initial board was formed, 1965 is when the office opened (the mission summary on Nhịp Cầu Giáo Lý gives 16 February 1965, corresponding to the full moon of the first lunar month of Ất Tỵ, while several other institute texts write 15 February 1965), 1970 is when the rebuilt headquarters was completed and inaugurated, and 1981 is when the institute took its present name. Whenever you encounter one of these dates, it helps to ask which milestone it refers to.
A second point worth clarifying concerns the street number. The institute's own mission summary notes that the 1965 office stood at 165E (now 171B) Cống Quỳnh Street, originally the private residence dedicated by Elder Thiện Bảo Ngô Chí Bình and Sister Ngọc Kiều Lê Thanh Kiều before the first stone was laid in 1969 to rebuild it into the present multi-story headquarters at 171B. In administrative terms, former Nguyễn Cư Trinh Ward of District 1 has now been merged into Cầu Ông Lãnh Ward.
IIIA working house of study, not a temple
Here the library writes more briefly than in other entries, and the reason lies in the nature of the site itself. Cơ Quan Phổ Thông Giáo Lý Đại Đạo is not built on the three-hall temple plan. There is no Hiệp Thiên Đài, no Cửu Trùng Đài with nine stepped floor levels, no Bát Quái Đài, and no bell or drum tower. That architectural framework serves the congregational liturgy of a church, whereas this place is not a church.
What it needs are rooms for reading, writing, lecturing, and discussion. Accordingly, the premises take the form of a multi-story urban working building erected between September 1969 and early 1970, matching the height and massing of contemporary town houses rather than a traditional shrine. Because the library has not located detailed architectural drawings of the building, it refrains from speculating on structural details and simply outlines the working spaces housed within.
An altar room enshrining the Divine Eye alongside the altar to Đức Phật Mẫu, where members observe the four daily services. This space keeps the building a true place of worship rather than a secular office, even though its scale is much smaller than that of a parish temple.
Spaces for doctrinal study courses, public lectures, and seminars attended by members from multiple Cao Đài churches. These rooms carry out the bridging role that the institute claims as its mission.
Repositories holding scriptures, spirit-writing messages (thánh giáo), and historical documents from many Cao Đài churches along with Confucian, Buddhist, and Taoist reference works. Much of this material has also been digitized into online book collections.
Workspaces where books and the institute's periodical are compiled and prepared for publication. For an organization centered on writing and scholarship, this is the core engine of the house even if it leaves no outward mark on the street facade.
Many visitors look up the address, arrive to find an urban building without towers or a forecourt, and assume they have come to the wrong place or that it is an unfinished small temple. Neither is true. The institute has no reason to erect a monumental sanctuary because it does not host mass festivals for thousands of pilgrims and has no territorial parish for congregational rites. An institute dedicated to doctrinal study needs bookshelves and lecture rooms far more than nine stepped floor levels, and the building here was designed to meet that exact need.
IVThe lie of the land and orientation
This section presents the library's reading through the lens of traditional geomancy (phong thủy), not something recorded in the institute's own documents. The library states this clearly so that readers can distinguish documentary records from interpretation. For a building raised for scholarship and study, it should be said plainly that its founders chose the site for practical convenience rather than geomantic formulas.
The first feature worth reading is not micro-topography but position within the city. The headquarters stands in the central district on a street linking several major thoroughfares, making it accessible from many directions without detours. In traditional siting terminology, such a central hub is called the central palace (trung cung), the middle square toward which all directions converge. For an institute acting as a bridge among Cao Đài churches across many provinces, occupying the central palace fits its function well regardless of whether geomancy was on the founders' minds.
Second is quiet ground within the city. Rather than fronting a roaring six-lane boulevard, the building sits along a moderate street, and its street number carries a letter suffix indicating a parcel set slightly back from the primary corner frontage. Classical geomancy distinguishes active ground (đất động), suited to places of mass gathering, from still ground (đất tĩnh), suited to study, writing, and contemplation. A spot stepped back from heavy traffic, quiet enough for reading yet close enough to reach easily, exemplifies still ground within an urban fabric. Had the task here been conducting grand ceremonies for thousands of people, this parcel would have been cramped, yet for studying and writing it is well matched.
Third is vertical massing. Because an urban lot is narrow in width and deep from front to back, the building develops vertically and inward rather than spreading horizontally. Read in traditional terms, a multi-story structure on a narrow lot channels qi upward along a vertical axis, following the time-honored urban custom of placing the most solemn altar room on the upper floor and working rooms below. This vertical arrangement appears in countless urban religious houses across Vietnam.
Finally, the library notes one point it has not surveyed. Because the library has not located a record giving the exact compass bearing of the front facade, it refrains from offering a directional eight-trigram reading based on guesswork. For an urban building whose orientation is fixed by the street grid, compass speculation would add little of substance.
VDaily worship and doctrinal work
Life at the institute runs along two parallel tracks. The first is the shared liturgical observance of Caodaism, maintained just as at other sanctuaries but on a compact scale. The second, which defines the distinct character of this address, is its schedule of doctrinal work encompassing classes, seminars, writing, and publishing.
| Occasion | Service or activity | Description |
|---|---|---|
| Four times daily | Four daily services (cúng tứ thời) | Services held at the four double-hours of Tý, Ngọ, Mẹo, and Dậu spaced evenly across day and night before the Divine Eye at the headquarters. |
| 9th day of the 1st lunar month | Festival of Đức Chí Tôn | The grand New Year festival and most solemn annual observance of Caodaism, celebrated at the headquarters on a compact scale. |
| Full moon of the 1st lunar month | Thượng Nguơn Festival | The first of the three full-moon cycle festivals (tam nguơn) of the liturgical year. |
| Full moon of the 7th lunar month | Trung Nguơn Festival | The mid-year cycle festival, including prayers for the deliverance of departed souls. |
| Full moon of the 8th lunar month | Festival of Đức Phật Mẫu | The autumn offering dedicated to the Maternal Principle (Đức Phật Mẫu) in the Cao Đài pantheon. |
| Full moon of the 10th lunar month | Hạ Nguơn Festival | The final cycle festival closing the annual liturgical round. |
| Year-round | Doctrinal courses and seminars | Classes on Cao Đài doctrine, lectures, and thematic seminars regularly attended by members from multiple Cao Đài churches. |
| Periodically | Publication of journals and books | Compiling, printing, and distributing the institute's periodical and doctrinal books, maintained steadily over several decades. |
Among all these activities, the most enduring mark is the periodical Cao Đài Giáo Lý. Published steadily over decades and now exceeding one hundred and fifty issues, each volume brings together research articles, doctrinal lectures, and historical documents. For an institution without its own lay congregation or subordinate temples, such a substantial journal is the clearest concrete proof of its bridging role, as its contributors and readers alike come from many different Cao Đài churches.
Alongside the journal stand the book collections. The institute preserves and compiles extensive archives, including collections dedicated to other Cao Đài churches and branches to which the institute itself does not belong. Individual churches rarely undertake such cross-branch documentation, and that archival work is the second reason the library includes this site under Places.
Regarding personnel numbers, an account written by an insider notes that the core resident and regular staff declined from roughly one to two hundred people in earlier decades to around forty or fifty people in recent years, the majority of them women. The library records this figure with its source so that readers can appreciate the true scale of the place, a small body in headcount that carries heavy weight in books and scholarship.

This is a place of study and worship rather than a tourist attraction, and it does not open onto a public courtyard like a large temple. Visitors are asked to dress modestly, remove shoes before entering the altar room, walk quietly, speak softly, and keep silence when a prayer service or class is in session. Anyone wishing to consult archival materials or attend a lecture should contact the desk in advance because the reading room and classrooms do not operate on open public-library hours. Please ask permission before taking photographs inside the sanctuary room.

?Quick Questions
Is Cơ Quan Phổ Thông Giáo Lý Đại Đạo a Cao Đài sect
No. It is neither a sect (chi phái) nor a parish temple (thánh thất). Official directories of Cao Đài churches do not list it as a church because it is a shared institute for doctrinal research and propagation, without its own lay membership, ecclesiastical hierarchy, or subordinate local temples.
What work does this institute do
It pursues three aims set out in its charter, namely universally transmitting the true dharma (phổ truyền chánh pháp), widely disseminating doctrine (phổ biến giáo lý), and universally aiding living beings (phổ tế quần sanh). In practice, it researches and compiles doctrine, publishes books and periodicals, holds study courses and seminars, maintains a reference library, and conducts charitable work across church lines.
When was Cơ Quan Phổ Thông Giáo Lý Đại Đạo founded
The answer depends on which milestone you mean. 1962 is when Ban Phổ Thông Giáo Lý Liên Quan Hành Đạo was formed, 1965 is when the first office opened at the full moon of the first lunar month of Ất Tỵ (sources record 15 or 16 February), 1970 is when the rebuilt headquarters at 171B Cống Quỳnh was completed (4 February) and inaugurated (22 March), and 1981 is when it adopted its present name on 18 May.
Why is the building not constructed like a Cao Đài temple
Because it has no territorial parish and does not hold mass congregational festivals. The three-hall layout of Hiệp Thiên Đài, Cửu Trùng Đài, and Bát Quái Đài serves the liturgical ceremonies of a church. A doctrinal institute needs a library, classrooms, and editorial offices, so its premises were built to match those functions.
What is the Cao Đài Giáo Lý periodical
It is the doctrinal journal published by the institute, issued steadily over several decades and now numbering more than one hundred and fifty issues containing research papers, lectures, and historical documents. Because its contributors come from many different Cao Đài churches, the journal stands as the clearest proof of the institute's role as an inter-church bridge.
