Caodaism (Vietnamese: o Cao ?ài, Ch? nôm: ) is a monotheistic religion officially established in the city of Tây Ninh in southern Vietnam in 1926. The full name of the religion is i o Tam K? Ph? (The Great Faith [for the] Third Universal Redemption).
Cao ?ài (Vietnamese: [k?:w ?â:j], literally the "Highest Lord" or "Highest Power") is the supreme deity, believed by Caodaists to have created the universe. Caodaists often use the term c Cao ?ài (Venerable High Lord) as the abbreviated name, whose full title is "Cao ?ài Tiên Ông i B? Tát Ma Ha Tát" ("The Highest Power [the] Ancient Immortal [and] Great Bodhisattva"). The symbol of the faith is the Left Eye of God, representing the yang (masculine, ordaining, positive and expansive) activity of the male creator, which is balanced by the yin (âm) activity of Mother Goddess, the Queen Mother of the West (Diêu Trì Kim M?u, Tây Vng M?u), the feminine, nurturing and restorative mother of humanity.
Adherents engage in practices such as prayer, veneration of ancestors, nonviolence, and vegetarianism with the goal of union with God and freedom from sa?s?ra. Estimates of the number of Caodaists in Vietnam vary; government figures estimate 4.4 million Caodaists affiliated to the Tây Ninh church, with numbers rising up to 6 million if other branches are added. An additional number of adherents in the tens of thousands, primarily ethnic Vietnamese, live in North America, Europe, and Australia. The design, shape and coloring of Caodaist temples is quite standard around the world and includes the incorporation of sacred images, symbols, and colors.

Ngô V?n Chiêu, a district head of the French administration in Cochinchina, was the first to worship and receive messages from Cao ?ài in 1921. He received a vision of the Divine Eye which is now the symbol for Cao ?ài as well as the focus for worship on all Cao ?ài altars.
Adherents maintain that on Christmas Eve 1925 God identified Himself to the first group of Cao ?ài mediums, which included Ph?m Công T?c, Cao Qu?nh C?, and Cao Hoài Sang. These three figures were to play an essential role in the growing religion as the three founding spirit mediums of the Hi?p Thiên ?ài or "Palace Uniting Heaven and Earth". Ph?m Công T?c was the head spirit medium or H? Pháp ("Defender of the Dharma), while Cao Qu?nh C? was the Thng Ph?m (his Sacred Assistant) and Cao Hoài Sang was the Thng Sanh (his Secular Assistant). 
On 7 Oct 1926, Lê V?n Trung (a former elected official of the Colonial Council of Cochinchina and a member of the Conseil de Gouvernement de l'Indochine), and a leading group of 27 Caodaists, the first disciples of Cao ?ài, signed the "Declaration of the Founding of the Cao ?ài Religion" and presented it to the French Governor of Cochinchina. The Cao ?ài faith brought together a number of once underground sects into a new national religion.
Officially called the "Great Way of the Third Time of Redemption" (i o Tam K? Ph? ), it became popular in its first few decades, gathering over a million members and converting a fifth to a fourth of the population of Cochinchina by 1940.
In the 1930s, the leader criticized the French colonial regime, though he also emphasized dialogue with the French. This stance was controversial, and contrasted with the liturgy of dozens of "dissident" branches of Caodaism that followed a more Taoist model.
During the First and Second Indochina Wars, members of Cao ?ài (along with several other Vietnamese sects, such as Hòa H?o) were active in political and military struggles against both French colonial forces and South Vietnamese Prime Minister Ngô ?ình Di?m.
Their critique of the communist forces until 1975 was a factor in their repression after the fall of Saigon in 1975, when the incoming communist government proscribed the practice of Caodaism. In 1997, Caodaism was granted legal recognition and free practice once again.

The Cao ?ài religion's (or Caodaism's) official name is i o Tam K? Ph? . Translated directly it means: The Third Great Universal Religious Amnesty. (i o - "Great Faith", Tam K? - "Third Period", Ph? - "to announce" and - "to save").
According to Cao ?ài's dogma, this Third Period will be of intense religious activity which will unite God and humanity in ways not yet imagined. Cao ?ài also states that the Third Amnesty will establish a new great faith for the salvation of living beings before the universal destruction. The primary objective of the Third Amnesty is the unity of all religions, which will bring mankind together in a universal family for universal peace.
Throughout human history, according to these beliefs, God the Father has revealed his truth many times through the mouths of many prophets, but these messages were always either ignored or forgotten due to humanity's susceptibility to secular desires. Adherents believe that the age has now come when God speaks to humanity directly.
In the nineteenth century, Spiritism became established in Europe. The likes of Madam Blavatsky, Allan Kardec and Victor Hugo championed new religious possibilities. In Vietnam, the age-old traditions of Asian divination and mediumship began to mix with the new traditions of European Spiritism.
To highlight this objective of unity, there is a representation of the Divine Covenant of The Third Amnesty (The Third Alliance) inside every Cao ?ài Temple. This Covenant between Heaven and Earth is written and presented to humanity by the Venerable Saints - Victor Hugo, Sun Yat Sen and Tr?ng Trình Nguy?n B?nh Khiêm. Their mission is said to guide humanity into the way of the Third Amnesty. The Covenant is written in French: "Dieu et Humanité Amour et Justice; and in Chinese: Tian Shang Tian Xia Bo Ai Gong Ping. This translates into English as: "God and Humanity [for] Love and Justice."
"Cao ?ài" refers to God the Father (the Supreme Being, the Creator, the Ultimate Reality of the Universe). Cao ?ài Tiên Ông i B? Tát Ma Ha Tát, as God's full title, indicates a combination of the three main religions - Confucianism, Taoism, and Chinese Buddhism.
Caodaists adopt the traditional Chinese idea of âm (yin) and dng (yang) duality constituting the harmonious balance of the universe. Before the creation of the universe there was the "dao", the infinite, nameless, formless, unchanging, eternal source. The negative and positive principles of the universe are the components of the eternal nature.
There are two main Gods, the Cao ?ài ("Highest Lord") and the Diêu Trì Kim M?u or c Ph?t M?u ("Holy Mother"). They represent respectively the yang and yin forces. Cao ?ài is viewed as the heart of the universe, the common Father of all beings. He imparts part of Him into each living being, including even rocks, in the form of conscience. c Ph?t M?u is venerated as the Mother of the universe, responsible for giving visible forms, consciousness and emotions to all life. Ultimately, She has to follow the orders of "c Cao ?ài", who is revered as the Supreme Being of both Heaven and Earth.
All other Divine Beings are to obey the orders of these two Creators during the course of evolution of the universe. Each of them carries a specific role as designated by their Father and Mother. Any being who falls out against them is considered devils in nature. These devils are led by the most powerful being, named Kim Quang S? (Satan).
In terms of the cosmos, faithful Caodaists believe there are heaven and hell, which are the main destinations for souls after death. Heaven consists of thirty six planes and many heavenly realms upon each of them, e.g. the Realm of Saints, the Realm of the Holy Mother, the Realm of the Perfect Beings, the Divine Court Realm, The Paradise of Extreme Joy, Nirvana, etc. Meanwhile, hell has ten key realms to carry out punishments in accordance with sins of souls.
In order to go to heaven, souls are required to cultivate their virtues and/or devote themselves to spiritual causes. Without merit from the latter, they cannot escape the cycle of birth and death, but can improve their virtues and merit gradually to reach better places in the universe, including the 72 planets (ours is the 68th), the 3,000 worlds, the four great cosmic regions, and the thirty six heavenly planes. True liberation can only be attained when souls reach Nirvana, i.e. the realm of Divine Beings with the most virtues, merits, and wisdom.
The father of the universe, Cao ?ài, is believed to have communed with men since the beginning of times, revealing his will. According to Cao ?ài doctrine, history is divided into three times (tam k?) of revelation. In the first two periods, there were teachings of Dipankara Buddha, sages, Ph?c Hy, Gautama Buddha, Laozi, Confucius and Jesus, who received the will of the Highest Power, and founded their respective religions to serve and/ or educate humanity. But due to the frailty of the messengers and the common men, the will of the Highest Power was misled into corrupted forms. Caodaists also believe that former revelations were culture-bound, being applicable only for certain ethnicities, and primarily intended for specific ages. The third and final form of revelation is disclosed through the teachings of the Cao ?ài faith.
Caodaists believe that there are various ranks of divine spirits: Th?n ("angels"), Thánh ("saints"), Tiên ("Immortals"), and Ph?t ("Buddhas"). Each of these ranks can be further divided in the three grades of Thiên (Heavenly), Nhân (Human) and a (Earthly), forming a twelve-fold hierarchy that reflects the twelve-fold earthly hierarchy of the Caodaist church. Below those ranks are the spirits of matters, plants, animals and humans. All spirits may evolve to attain higher rank based on present deeds. Disembodied spirits fulfill a number of roles: they are benefactors of mankind, messengers and instructors of the truth.Quan Âm is regarded as the exemplary goddess of the Buddhas, Lý B?ch of the Immortals, and Quan V? of the Saints.
Unknown to most outsiders, Joan of Arc is worshipped in the Cao ?ài pantheon. She is seen as having guided the Faith at its inception and promoted full equality for women (via séances). The Cao ?ài pantheon also has many other well-known figures, including Muhammad, Moses, Louis Pasteur, Shakespeare, and Lenin.Victor Hugo is probably the most important European figure to play a role in the Caodai pantheon, since he gave many teachings and also the text of a number of important prayers. He himself practiced spiritism on the island of Jersey from 1852 to 1855, and predicted that he would become the prophet of a new religion to merge European and Asian mysticism. Reports that Winston Churchill and Charlie Chaplin were also "saints" are based on an inaccurate 1956 Time magazine article, since both of them were still alive at the time.
The doctrines of the Cao ?ài faith tends not only to reconcile all religious views, but also to adapt itself to all degrees of spiritual evolution. A basic principle of Caodaism is "All Religions are One". Cao ?ài has been described from five different points of view:
Believers worship God the Father, Holy Mother and the Divine Beings with all their heart. They also venerate the Great Religious Prophets of history and honour the ancestors.
There are four daily ceremonies, that is, at 06:00, Midday, 18:00 and midnight, either at the temple or in front of the home altar. Monthly rituals take place on midnight of the 1st and 15th days of the lunar month. There is also a special anniversary ceremony once a year for God the Father, the Holy Mother, the five founders of the world's major religions, and the founders of the Cao Dai religion. The rituals differ between places, depending on who they pray to.
There are also differences between monthly rituals, and anniversary ones.
Ceremonial prescriptions such as actions, dress and music were organized in detail by God the Father. These include ceremonies for initiations, marriages and funerals. Particular attention is paid to death, and it has been revealed to the religion how the soul journeys towards heaven and how, on earth, co-religionists can pray for souls to help them on their way.
Cao ?ài temples and religious buildings host a rich array of symbols, all of which are instructed by either God the Father or Divine Beings. No symbol is redundant, and none is meaningless. They each tell a different story that reveals the beliefs, values, cosmic secrets, prophecies, etc. When combined, they lay out the journey of the Tao throughout the history of mankind and the universe, as well as its way forward.
In spirit and in pictorial representation, the Eye serves to remind Cao ?ài believers that the God witnesses everything, everywhere, constantly. At the Holy See, there are in total 50 Divine Eyes of five different shapes; each carrying a different meaning related to various spiritual aspects. The One on the globe shows the Supreme Being above the North Star in the Ursa Minor constellation. The One on the façade of the Holy See has 35 rays of light which represent the three major religions and five main religious doctrines of the world. At the local Cao ?ài Temples, the Divine Eye has 16 rays of light emanating from it. Nine radiate upward representing the nine levels of heaven, and seven radiating downward representing the seven emotions, which believers must control.
In accordance with the religious mission, the three colors of Cao ?ài banner represent the three main religions of the world; yellow stands for Buddhism, blue for Taoism, and red for Confucianism. Under the Divine Eye is the religious emblem which also represents the essence of the three religions; the bowl of charity for Buddhist compassion and asceticism, the feather duster for Taoist purification; the Spring and Autumn Annals for Confucianist virtue and love.
There are various Caodaist scriptures. Some of those belonging to the Holy See of Tây Ninh are: Kinh Thiên o Và Th? o ("Prayers of the Heavenly and the Earthly Way"),[need quotation to verify]Pháp Chánh Truy?n ("the Religious Constitution of Cao ?ài Religion"),Tân Lu?t ("The Canonical Codes"),  and Con ng Thiêng Liêng H?ng S?ng ("Divine Path to Eternal Life"). Other sects have additional scriptures.
This scripture sets out the rules and boundaries for different aspects of the religion, from a believer to the Pope, from education to marriage, etc. There are ten sections in the scripture with the following content:
The Phap-Chanh-Truyen (The Religious Constitution of Caodaism) was delivered to the religion as a series of divine messages. These are the guiding texts of the religion's organisation, stipulating the authority, responsibility, limits, as well as religious vestment for each rank in the religion.
The organisational structure of the Caodaist church has similarities with that of a state. There are similarities between the hierarchy of the Caodaist clergy and that of the Catholic Church. Besides the Pope, the Caodaist hierarchy has Cardinals, Bishops, Priests, and further ranks.
Caodaism stresses equality among men and women in society. However, in the spiritual domain, ordained women may not attain the two highest positions: the Legislative Cardinal and the Pope. The church claims this is ordered by the Highest Lord, who declared that because Dng (Yang) represents male and Âm (Yin) corresponds to female, Yin cannot dominate Yang spiritually or else chaos ensues.
The Religion is governed by two powers, the spiritual and earthly ones.
The spiritual power (Bát Quái ?ài): This is the heavenly council, that is, the Spirit and Soul of the New Religion. The council directs all activities of the universe. The council is the invisible part, made up of the Divine Beings, and directed by Duc Cao Dai (God the Father). The Divine Beings represent different religions of the world, including:
The earthly power: To avoid dictatorship, God divided the earthly power into two bodies - an Executive Body (C?u Trùng ?ài) headed by the Pope, and a Legislative Body (Hi?p Thiên ?ài) headed by the H? Pháp (Protector of Laws and Justice). The former takes charge of the administration of the Religion and its missionary activities, while the latter oversees legislation, jurisdiction and communication with God or Divine Beings. There is also the Charitable Body placed under the supervision of the Legislative Body, and a Lay Committee of selected professional specialists among worthy followers.
The C?u Trùng Ðài is the Executive Body of Caodaism which takes charge of the administration of the Religion and missionary activities. Head of C?u Trùng Ðài is Giáo-Tông (Pope).
The Giáo-Tông (Pope) represents God to watch over the preservation of His Religion in this world. Whatever his age, he is eldest brother and acts as a guide for the children of God. The Spiritual Power has decided that this is so. The Giáo-Tông (Pope) has the same powers as God to teach Virtue to all His Disciples. He is concerned with each one of them, he guides each one and takes care to ensure that each one does not transgress the Divine Laws (Thiên ?i?u). He obliges all disciples of God to conform strictly to the prescriptions of the New Codes (Tân Lu?t)... Since the Giáo-Tông (Pope) has full powers to replace God he must try to transform the life of suffering into an existence marked by happiness. This is the Exalted Task of the Giáo-Tông (Pope).
There are nine ranks in its hierarchy:
For male dignitaries of the Executive Body, from the rank of Censor Cardinal to that of Student Priest, each echelon is subdivided into three branches corresponding to the three principal religions:
Dignitaries of the same echelon, either Confucianist, Taoist or Buddhist, have the same attributes.
At the Holy See, there are three governing councils:
All plans made by the Popular Council and favoured by the Sacerdotal Council are submitted to High Council for approval.
In addition, there is also a Central Administration body chaired by three Cardinals. Each of them is assisted by three Principal Archbishops to oversee three religious ministries:
The administrative network which functions throughout Vietnam consists of:
This Body has the duty of communicating with Divine Beings, to preserve the religious laws and listen to the complaints of the unhappy. It is headed by the H? Pháp (protector of laws and justice), and assisted by the Thng Ph?m (Director of religious affairs) and Thng Sanh (Director of secular affairs).
Four "zodiacal dignitaries" under each of these branches carry the four key responsibilities of conservation, renovation, reformation, and legislation. They are further assisted by twelve technical academicians, including B?o Huy?n Linh Quân (Theosophy), B?o Tinh Quân (Astronomy), B?o Cô Quân (Orphanage), B?o V?n pháp quân (Culture), B?o H?c Quân (Education), B?o Y Quân (Health), B?o V?t Quân (Science and Industry, B?o S? Quân (Literature), B?o Sanh Quân (Social work), B?o Nông Quân (Agriculture), B?o Công Quân (Public Works), B?o Thng Quân (Economics).
Any local area having more than 500 believers is authorized to establish a Parish (H? o/ T?c o) with a Thánh-Th?t (Temple, Church, Holy House) which is led by the authority of a dignitary. Parish/Parishes can be established only with the permission and authority of the Giao-Tong/ Pope.
Twice a month, the first and the fifteenth day of the lunar calendar, the believers must meet at the Thánh-Th?t (Temple, Holy House) of the local area to attend the ceremony and listen to the teachings. Exception can be made for those with reasonable excuses
Ninety kilometres north-west of Saigon in Tây-Ninh Province is the Caodaist Holy See. At the centre of this city stands the Great Divine Temple. This temple, like the religion, is a fusion of world influences. As well as being a major centre of pilgrimage, the Caodaist Holy See is also one of Vietnam's major tourist attractions.
In total, there are six different officially recognized branches of the Caodaist religion in southern Vietnam, as well as several others that remain unrecognized. These sects generally divide along geographic lines. The largest is based in Tây Ninh Province, where the religion was founded in 1926 and where the seat of the Caodaist authority is located.
The Caodaist Executive Council of Tây Ninh Province received official government recognition in 1997. Independent Caodaist groups allege that government interference has undermined the independence of the Tây Ninh group, and it no longer faithfully upholds Cao ?ài's principles and traditions. Religious training takes place at individual temples rather than at centralized seminaries. Some Caodaist sects that have broken away from the Tây Ninh Holy See are Chi?u Minh, B?n Tre, and ?à N?ng. Ngô V?n Chiêu founded Chi?u Minh when he left the original church structure, refusing his appointment as Caodaism's first pope.
