Bahá'u'lláh (1817-1892)

To understand the appearance of Bahá'u'lláh, we must imagine Persia in the middle of the 19th century: a kingdom governed by the Qajar dynasty, of the Twelver Shiite faith - the branch of Islam awaiting the return of a twelfth "hidden" imam since the 9th century, the Mahdí or Qá'im ("He who rises"), supposed to restore justice before the end of time.^[1]

The Shaykhite movement and the wait for the Qá'im

At the turn of the 19th century, Chaykhism, an esoteric Shiite movement founded by Chaykh Ahmad al-Ahsá'í (1753-1826), developed in Persia and Iraq, which insisted on the imminence of the return of the Qá'im and on the need to discern his "Door" (báb) - the intermediary through whom he could be recognized.^[2] This intense messianic expectation, carried by thousands of Chaykhite disciples, directly prepared the ground on which the preaching of the Báb would arise, in 1844.

The declaration of May 22, 1844

On the evening of May 22, 1844, a young merchant from Chíráz, Siyyid Ali-Muhammad (1819-1850), declared himself before his first disciple, Mullá Husayn-i-Bushrú'í, to be the Báb — “the Door” — announcing the imminence of a new divine revelation intended to prepare “He whom God will manifest”.^[3] This date — retained by the Bahá'í calendar as that of the "declaration of the Báb" — is celebrated today as one of the major holy holidays of the Bahá'í Faith.

The Bábí movement quickly won tens of thousands of adherents in Persia, but encountered violent opposition from the Shiite clergy and the Qajar power: several Bábí insurrections were bloodily crushed between 1848 and 1850.^[4]

The martyrdom of the Báb (July 9, 1850)

In July 1850, the new prime minister Amír Kabír, judging the movement weakened but still dangerous, ordered the execution of the Báb. On July 9, 1850, in Tabríz, the Báb, aged thirty, was shot in front of a large crowd — a first platoon would have, according to Bábí and then Bahá'í tradition, missed its target before a second carried out the execution.^[5] Several thousand Bábís were then put to death in the repression that followed.^[6]

Shortly before his death, the Báb had designated his younger half-brother, Mírzá Yahyá, later known as Subh-i-Azal, as the nominal leading figure of the movement - the exact nature of this designation (real succession or symbolic protection, according to the later Bahá'í reading) remains debated by historians.^[7] This question of succession would resurface, fifteen years later, in the rupture between Subh-i-Azal and his own older half-brother, Bahá'u'lláh.

Birth and family (1817)

Mírzá Husayn-Alí Núrí was born in Tehran on November 12, 1817, into a family of Persian nobility originating from the district of Núr, in the province of Mázandarán.^[8] His father, Mírzá Abbás Núrí, known as Mírzá Buzurg, held the position of vizier to Imám-Virdi Mírzá, twelfth son of Shah Fath-Ali Shah Qajar.^[9] This birth into the court aristocracy ensured him, in principle, a clear-cut administrative career.

The “Father of the Poor”

However, from his youth, Mírzá Husayn-Alí refused the official career that his birth opened up to him and devoted his time and his fortune to charitable works, which earned him, even before his thirtieth year, the nickname "Father of the poor".^[10] This reputation for generosity and moral integrity, well established in Tehranese society, partly explains the rapid influence that he would soon wield over the small Bábí community.

In 1844, he adhered to the Báb's message, without ever having met him in person, and became one of his most fervent supporters in Persia, under the Bábí title of Bahá ("the Splendor").^[11] His house served as a meeting place for the Bábís of the capital, and he corresponded with the Báb, who sent him several tablets recognizing his particular rank within the movement.

The failed attack against the Shah and the repression

On August 15, 1852, a small group of Bábís radicalized by the execution of the Báb and by two years of persecution attempted to assassinate the shah Nasser al-Din. The attack failed, but it triggered a fierce repression against the entire Bábí community, including those who, like Bahá'u'lláh, had publicly condemned the plot.^[12] Bahá'u'lláh was arrested and led on foot, in chains, to the Síyáh-Chál ("the Black Pit"), a former underground water reservoir in Tehran converted into a dungeon.^[13] He remained incarcerated there from August to December 1852, in almost total darkness, chained alongside approximately one hundred and fifty other prisoners - most of them common criminals - without sanitary facilities and with limited food.^[14] It was in these extreme conditions that, according to the Bahá'í account, the decisive turning point in his life took place: Bahá'u'lláh received there, in October 1852, a series of mystical experiences, which he would later interpret as the investiture of his mission as “Manifestation of God” announced by the Báb.

The vision of the “celestial Virgin”

Bahá'u'lláh himself describes this experience, years later, in the Súriy-i-Haykal, in the form of a vision of a female figure - the "Heavenly Virgin" (Húrí), also called "Daughter of Heaven" - who is said to have announced to him his mission:

“While I was overwhelmed with tribulations, I heard a very sweet and wonderful voice rising above My head. Turning My face, I saw a Maiden—the embodiment of the remembrance of My Lord's name—suspended in the air before Me. So great was her joy that she radiated the good pleasure of God, and her cheeks shone with the radiance of the All-Merciful. Between Earth and Sky, she raised a call that captivated the hearts and minds of men." — Bahá'u'lláh, Súriy-i-Haykal ("Surah of the Temple"), written in Adrianople, c. 1868, English text published by the Bahá'í Reference Library.^[15]

It was also during this captivity that, according to Bahá'í accounts, his gradual break with his younger half-brother Mírzá Yahyá began, who had meanwhile fled Tehran and refused to take any share of responsibility for the events.^[16]

Liberation and banishment

After four months of detention, Bahá'u'lláh was released in December 1852, on the express condition of definitively leaving Persia. His property was confiscated, his family stripped of its fortune.^[17] In January 1853, in the middle of winter, he left with his family for Baghdad, then a province of the Ottoman Empire — the first link in an exile which would only end with his death, almost forty years later.

Baghdad (1853-1863) and Kitáb-i-Íqán

In Baghdad, Bahá'u'lláh gradually gathered around himself again the small, scattered Bábí community. Tensions with his half-brother Mírzá Yahyá, jealous of the ascendancy he exercised, pushed him in 1854 to retire alone, for about two years, to the mountains of Sulaymaniyah, in Ottoman Kurdistan, before returning to Baghdad in 1856 at the urging of his family and the Bábís.^[18] It was during this second Baghdad period that he composed his major youthful works: the Hidden Words (1858), a collection of spiritual aphorisms, and especially the Kitáb-i-Íqán ("Book of Certainty", 1862), a long theological treatise in which he sets out his reading of the biblical and Koranic prophecies announcing, according to him, his own coming.^[19]

“No man will reach the shores of the ocean of true understanding if he does not detach himself from everything that is in heaven and on earth. Sanctify your souls, O people of the world, that you may attain the station which God has destined for you." — Bahá'u'lláh, Kitáb-i-Íqán (The Book of Certainty), first paragraph, English trans. Shoghi Effendi, Bahá'í Publishing Trust, Wilmette, 1970.^[20]

The Declaration of the Garden of Ridván (April 1863)

In 1863, under the combined pressure of the Persian government and the Shiite clergy of Iraq, the Ottoman authorities summoned Bahá'u'lláh to Constantinople. Before his departure, from April 21 to May 2, 1863, he stayed for twelve days in the garden of Najibiyyih, on the banks of the Tigris, since renamed “Garden of Ridván” (“Paradise”). It was there that, for the first time, he declared to a small circle of companions that he was "He whom God will manifest" - the divine Manifestation announced by the Báb.^[21] These twelve days, celebrated each spring as the feast of Ridván, are considered by the Bahá'ís as the holiest of their feast days, that of the effective birth of their religion.

Constantinople and Adrianople (1863-1868)

The stay in Constantinople lasted only four months: from December 1863, under Persian pressure, the Ottomans banished Bahá'u'lláh again to the provincial city of Adrianople (present-day Edirne, in European Turkey), where he remained until 1868.^[22]

It was in Adrianople that he made his mission public, proclaiming it openly to the entire Bábí community, then wrote, between 1867 and 1873, his famous Tablets to the Kings (Súriy-i-Mulúk), letters addressed to the sovereigns of the world - the Ottoman Sultan Abdülaziz, Tsar Alexander II, Emperor Napoleon III, Queen Victoria, the Shah of Persia and, later, Pope Pius IX — calling on them to recognize his mission and work for justice and universal peace.^[23]

The break with Subh-i-Azal

It is also in Adrianople that the open rupture between Bahá'u'lláh and Mírzá Yahyá, who became Subh-i-Azal ("the Dawn of Eternity"), was consummated. In 1866, the latter allegedly tried to poison his older half-brother; Bahá'u'lláh survives, but keeps a tremor in his hand all his life.^[24] The break is definitive: the supporters of Bahá'u'lláh become the bahá'ís, those of Subh-i-Azal the azalis - a minority current which will gradually die out during the 20th century.^[25]

The prison town of Saint-Jean-d’Acre (1868-1892)

In August 1868, fueled by Azal's accusations and new Persian pressure, the Ottoman authorities permanently banished Bahá'u'lláh, his family and his companions to the prison town of Saint-Jean-d'Acre, in Ottoman Palestine - one of the harshest penitentiary places in the empire, reserved for the most dangerous convicts. He arrived there on August 31, 1868.^[26] The first years were trying: the family was confined in an unsanitary barracks, and in 1870 his youngest son, Mírzá Mihdí, died after falling through a glass roof of the prison roof, on which he was walking while praying.^[27] Little by little, however, the exemplary conduct of Bahá'u'lláh and his companions won the respect of the authorities and local inhabitants: the conditions of detention were gradually eased, allowing him, from 1877, to reside outside the city walls, first in Mazra'ih, then, from 1879, in the mansion at Bahji, where he spent his last thirteen years — still formally a prisoner of the Ottoman Empire, but in much more lenient conditions.^[28]

It was in Acre, around 1873, that he wrote his major work of legislation, the Kitáb-i-Aqdas.

Bahá'u'lláh was a remarkably prolific author: Bahá'í tradition attributes to him more than a hundred volumes of tablets, letters and treatises, written mainly in Arabic and Persian during his forty years of exile and captivity.^[29] Four texts dominate his corpus.

The Hidden Words (1858)

Written in Baghdad, the Hidden Words (Kalimát-i-Maknúnih) is a collection of short spiritual aphorisms, presented as the synthesis of the “essence” of the ancient teachings of the prophets, in Arabic then in Persian.^[30]

“O Son of the Spirit! I created you rich, why do you make yourself poor? I made you noble, why do you degrade yourself?" — Bahá'u'lláh, The Hidden Words, Arabic section, § 13, English trans. Shoghi Effendi, Bahá'í Publishing Trust, Wilmette, 1985, text published by the Bahá'í Reference Library.^[31]

The Kitáb-i-Íqán, Book of Certainty (1862)

Already mentioned above, this Baghdad treatise constitutes Bahá'u'lláh's most developed theological exposition on the nature of successive revelation, the symbolic reading of biblical and Koranic prophecies, and the status of the Báb as direct precursor of his own coming.^[32]

The Kitáb-i-Aqdas, The Most Holy Book (1873)

Written in Acre around 1873, the Kitáb-i-Aqdas is the book of laws of the Bahá'í Faith, described by tradition as "the Mother Book" of its teachings and "the Charter of the future world civilization".^[33] Bahá'u'lláh sets out the ritual obligations (daily prayer, nineteen-day fast), the prohibitions (alcohol, begging), the institutions (House of Justice called to legislate on what the text does not explicitly decide), the Bahá'í calendar of nineteen months of nineteen days, and numerous social prescriptions.^[34] The text only gradually circulated among the faithful from the 1880s and was published for the first time in Bombay in 1890-1891.^[35]

The Tablets of Kings

Between 1867 and 1873, Bahá'u'lláh addressed a series of solemn letters to the sovereigns of the world, gathered in the Súriy-i-Haykal ("Surah of the Temple"): to the Ottoman Sultan Abdülaziz, to Tsar Alexander II, to Napoleon III, to Queen Victoria, to Nasser al-Din Shah - and, in 1869, to Pope Pius IX.^[36]

This text, known in Persian as Lawh-i-Páp ("Tablet to the Pope"), deserves special attention in a Catholic article, because Bahá'u'lláh addresses it directly to the head of the Catholic Church, presenting himself as the return of Christ awaited by Christians and exhorting him to renounce the temporal riches of the papacy:

“Sell all the precious ornaments you own, and spend them on the path of God, Who makes night return to day and day to night." — Bahá'u'lláh, Lawh-i-Páp (Tablet to Pope Pius IX), v. 1869, in The Proclamation of Bahá'u'lláh, Bahá'í Publishing House, Wilmette, p. 81-86, English text available via bahai-library.com^[37]

“Abandon your kingdom to the kings, and leave your home, your face turned towards the Kingdom." — Bahá'u'lláh, Lawh-i-Páp, ibid.^[38] Bahá'u'lláh reproaches the Pope for living in palaces while, according to him, the "returned Messiah" remains in the greatest poverty, and warns him not to let attachment to the sole name of Jesus veil from him the recognition of "the reality of the Lord of the heavens and the earth".^[39] This document, in itself, concretely illustrates the central doctrinal issue of this article: Bahá'u'lláh does not present himself as a simple religious sage among others, but as one who accomplishes and exceeds the revelation of Christ itself - a claim to which the Catholic Church cannot, by nature, subscribe (see below).

Death in Bahji (May 29, 1892)

After a brief feverish illness, Bahá'u'lláh died at the mansion of Bahji on May 29, 1892, at the age of seventy-four. He is buried in a building adjoining the residence, which has since become the Sanctuary of Bahá'u'lláh - the holiest place of the Bahá'í Faith, to which its faithful turn today for daily prayer (the Bahá'í qiblih).^[40]

The Covenant and the succession of 'Abdu'l-Bahá

In his will, the Kitáb-i-'Ahd ("Book of the Covenant"), Bahá'u'lláh designates his eldest son, 'Abbás Effendi, known as 'Abdu'l-Bahá (1844-1921), as the sole authorized interpreter of his writings and leader of the Bahá'í community.^[41] Bahá'í tradition presents this designation in writing and without ambiguity as an unprecedented fact in the history of the founding religions.^[42] 'Abdu'l-Bahá would in turn name, in his own will, his grandson Shoghi Effendi (1897-1957) as "Guardian" of the Faith; this will prepare the establishment of the Universal House of Justice, the supreme body of Bahá'í governance, elected for the first time in 1963 and still in office today in Haifa.^[43]

The Manifestations of God and progressive revelation

The heart of Bahá'í theology is the doctrine of the Manifestations of God (Mazáhiru'lláh): God, absolutely unknowable in His essence, reveals Himself to men through a succession of envoys - among whom the Bahá'í tradition cites Abraham, Krishna, Moses, Zoroaster, the Buddha, Jesus, Mohammed, the Báb and finally Bahá'u'lláh - each bringing the same eternal spiritual truths, adapted to the needs and maturity of his time.^[44] This theory, called progressive revelation, maintains that “religions are fundamentally one” and that the truth is revealed in successive stages throughout history.^[45]

Bahá'u'lláh goes further: he presents himself as the simultaneous fulfillment of the eschatological expectations of all the great religious traditions at once — the return of Christ for Christians, the twelfth Imam for Shiites, the fifth Buddha (Maitreya) for Buddhists, the Kalki avatar for Hindus, Sháh Bahrám for Zoroastrians.^[46] It is this claim to the unification of all religious eschatologies in a single person that constitutes the crux of the Catholic disagreement, examined below.

The unity of God, religions and humanity

Three affirmations structure the entire Bahá'í teaching: the unity of God (strict monotheism, without distinction of persons), the unity of religion (all the great religions come from the same divine source) and the unity of the human race, presented as "the sovereign remedy and the most powerful instrument for the healing of all people".^[47]

“What the Lord has ordained as the sovereign remedy and the most powerful instrument for the healing of all people is the union of all his peoples in a single universal Cause, a single common Faith." — Bahá'u'lláh, Tablets of Bahá'u'lláh revealed after the Kitáb-i-Aqdas, Bahá'í Publishing House, Wilmette, 1988, text published by the Bahá'í Reference Library.^[48]

Social law and institutions

The Kitáb-i-Aqdas and later tablets set out a body of social principles often presented as progressive for the time: equality of men and women, compulsory universal education, harmony between science and religion, adoption of a universal auxiliary language, reduction of extremes of wealth and poverty, abolition of prejudices of race and nation, federal world government and universal "Great Peace".^[49] The Bahá'í Faith has neither clergy nor sacraments: its government rests on elected councils - local and national spiritual assemblies, then the Universal House of Justice - and not on an ordained ministry.^[50]

Worldwide distribution and holy places

Demographic estimates vary according to sources, between approximately five and eight million believers spread across more than two hundred countries and territories — which would make it, according to some sociological studies, the most geographically widespread religion after Christianity.^[51] The Shrine of Bahá'u'lláh in Bahji, near Acre, and the Shrine of the Báb, on Mount Carmel in Haifa, whose remains were transferred from Persia in 1909, together form the Bahá'í World Center. In July 2008, UNESCO inscribed all of the "Bahá'í Holy Places of Haifa and the Western Galilee" — shrines, terraces, gardens and annexed buildings — on the World Heritage List.^[52]

Persecution in Iran, yesterday and today

Since its birth, the Bahá'í faith has suffered repeated persecution in Iran, its country of origin: local massacres in the 19th and early 20th centuries, then systematic repression since the Islamic revolution of 1979, which does not recognize the Bahá'í religion and considers its followers to be apostates from Islam.^[53] The Bahá'ís of Iran — approximately 300,000 people, the country's largest non-Muslim religious minority — are denied access to public higher education, suffer confiscation of property and arbitrary arrests.^[54]

According to Human Rights Watch, between June and November 2025, more than 750 acts of persecution were documented across Iran — three times more than the same period in 2024 — including more than two hundred searches and the arrest of at least one hundred and ten Bahá'ís; in October 2025, ten Bahá'í women from Isfahan were sentenced, cumulatively, to ninety years in prison for organizing educational and cultural activities.^[55] The organization describes this systematic repression as a "crime of persecution" under international law.^[56]

Once the life and the doctrine have been presented, a question remains, decisive for the Catholic reader: what to think of Bahá'u'lláh's claim to accomplish, including, the Christian revelation? The Church's response is based on a central principle of faith, not contempt for a religion with genuine moral values.

Public Revelation is closed with Christ

Christianity holds that God said everything he had to say in his Word made flesh. Christ is not one Manifestation among others in an open series: he is the definitive Word of God, after which no new public revelation is to be expected:

“The Christian economy, being the new and definitive Alliance, will therefore never pass away and no new public revelation is therefore to be expected before the glorious manifestation of our Lord Jesus Christ." — Catechism of the Catholic Church, § 66, citing the Second Vatican Council, dogmatic constitution Dei Verbum, § 4^[57]

The Catechism further specifies that the Christian faith cannot accept "revelations" which would claim to exceed or correct that of which Christ is the completion.^[58] But this is exactly what Bahá'u'lláh claims when he addresses Pope Pius IX, presenting himself as the very return of Christ, bearer of a teaching that would complete and surpass the Gospel. From the Catholic point of view, such a claim cannot, by construction, be received as divine.

The problem of religious relativism: Dominus Iesus

The Bahá'í doctrine of "progressive revelation" - according to which Jesus, Mohammed, the Báb and Bahá'u'lláh are successive Manifestations of equivalent rank of the same God - corresponds precisely to what the Congregation for the Doctrine of the Faith explicitly condemned in the declaration Dominus Iesus (2000): the thesis of a "limitation, incompleteness or imperfection" of the revelation of Christ, which other revelations would complete.^[59]

“It would be […] contrary to faith to consider the Church as a path to salvation alongside those constituted by other religions, considered complementary to the Church, or even substantially equivalent to it." — Congregation for the Doctrine of the Faith, declaration Dominus Iesus, August 6, 2000, § 21^[60]

The Bahá'í theory of Successive Manifestations is a textbook case of the religious pluralism that Dominus Iesus directly targets: it does not deny that Jesus was an authentic envoy of God - it relativizes him, by placing him on the same level as Buddha, Mohammed, the Báb and Bahá'u'lláh, and by presenting the latter as the one who goes beyond and closes the series. Christianity, conversely, considers Christ not as a stage of a still open revelation, but as the unique, definitive and unsurpassable Word of God made man.^[61]

What the Church recognizes as true and good

This doctrinal firmness does not exclude a sincere recognition of what can be good in the life and moral teaching of Bahá'u'lláh and his disciples. The Catechism teaches that the Church considers “whatever good and true may be found in religions” “as evangelical preparation”^[62]; the love of peace, the fight against racial prejudice, the demand for social justice and the courage of Bahá'ís persecuted in Iran for their faith deserve respect. But recognizing elements of moral goodness is not equivalent to recognizing a divine revelation: this is precisely the distinction that Dominus Iesus carefully maintains, between the “elements of truth and grace” present outside the visible structure of the Church and the affirmation, specific to Christ alone, of being “the way, the truth and the life”.^[63]

Esteem people, discern doctrine

The Catholic position therefore holds together two requirements that are often wrongly opposed. On the one hand, a real respect for the Bahá'ís, many of whom today even suffer from state persecution in Iran for their religious affiliation alone - a cause for which the Church, attached to the religious freedom of every person, can and must associate itself without reservation.^[64] On the other, fidelity to the truth of the Faith: Bahá'u'lláh, whatever his personal courage in the face of forty years of exile and captivity, is not for the Church a Manifestation of God, and his claim to accomplish the revelation of Christ - to the point of writing as much to the Pope himself - cannot come from God, since the Revelation was definitively completed in Christ. This double fidelity – to charity towards people and to the truth about doctrines – is the specific mark of the Catholic outlook, equidistant from contempt and syncretism.

Unlike Muhammad, who founded a distinct religion without ever claiming to be the returned Christ, Bahá'u'lláh formulates an even more radical claim: he is not content with proposing a new prophecy, he claims to unify and close all of the religious revelations of humanity in his own person - which makes all the clearer, from the Catholic point of view, the fundamental incompatibility between his claim and faith in Christ, the only Savior and Redeemer of the world.

• Muhammad (c. 570-632) — another founder of religion born in the Middle Eastern world, whose prophetic claim is examined using the same method.
• Siddhartha Gautama, the Buddha (c. 563–c. 483 BC) — also included by Bahá'u'lláh in his chain of Manifestations of God.
• Did Jesus Really Exist? — the historical foundations of the person with whom Bahá'u'lláh claims to identify.
• The Resurrection of Jesus (c. 30-33) — the Resurrection and the glorious return of Christ in the face of claims of a “second coming”.
