The Mormons

The "Burned-over District" and the 19th-century religious ferment

Joseph Smith was born on December 23, 1805, in Sharon (Vermont), into a poor and unstable family, and grew up in Palmyra, in western New York State. This region was then swept by a succession of Protestant "revivals" so intense that the revivalist preacher Charles G. Finney spoke of a "burnt district" — a district where so much preaching had been done that no religious fuel remained to ignite — in his Autobiography (1876)^[7]. The historian Whitney R. Cross adopted the phrase as the title of his landmark 1950 study of the region^[8]. Methodists, Baptists, Presbyterians, Disciples, communal sects: competition was fierce, and a young man anxious about his salvation could feel that no one held the truth.

Added to this was a popular culture of magic, inherited from English almanacs and divination by rod, dream or seer stone. The Mormon historian D. Michael Quinn showed in an exhaustive study that the Smith family was immersed in this mental world.^[9] Buried treasures were sought with the help of magic stones, dreams were heeded, astrological parchments were kept. Joseph Smith Jr. himself was known in the 1820s as a "glass-looker" — a "seer-stone gazer".

The 1826 "glass-looking" proceeding

On March 20, 1826, at South Bainbridge (Chenango County, New York), Joseph Smith appeared before Justice Albert Neely on a charge of being a "disorderly person", under a New York State law forbidding anyone "to pretend to discover where lost goods may be found"^[10]. The justice's bill expressly identifies him as "The Glass Looker". The primary documents — Neely's and Constable De Zeng's bills — were recovered in 1971 by Wesley P. Walters in the basement of the Norwich (NY) courthouse.

The LDS Church, after decades of playing it down, now officially mentions this 1826 proceeding on its institutional website^[11]. A nuance is in order, however: while the existence of the March 20, 1826 hearing before Justice Neely is established by the bills recovered in 1971, its exact nature — preliminary examination or full trial — and its outcome (acquittal, conviction or mere dismissal) remain debated among historians, for want of a judgment minute. What the documents firmly establish is that Joseph Smith, at 20 — six years after his "First Vision" and three years before the alleged translation of the Book of Mormon — was already known as a "glass looker". It was with this same method (face buried in a hat around a seer stone) that he would then dictate the Book of Mormon^[12].

The multiple accounts of the "First Vision"

Mormonism rests on a founding narrative: in 1820, the young Joseph, troubled by the religious disputes of the Burned-over District, is said to have gone to pray in a grove and there to have seen God in person. Yet there are at least four different accounts of this episode, written or dictated by Joseph Smith himself between 1832 and 1842, and these accounts do not say the same thing. For more than a century, only the latest version was circulated. The other accounts remained very little known and were brought to public attention only in the 1960s-1970s; the Church has since published them in the Joseph Smith Papers Project and acknowledged them in an official Gospel Topics Essay published in 2013^[13].

The handwritten 1832 account

The earliest account is in Joseph Smith's own hand, in a notebook dated summer 1832. It mentions a single divine personage: the Lord Jesus, who descends in a pillar of fire to forgive his sins. Smith states that, before this vision, he had already concluded from studying the Scriptures that all the churches had apostatized.^[14]

"By searching the scriptures I found that mankind did not come unto the Lord but that they had apostatized from the true and living faith. […] The Lord opened the heavens upon me and I saw the Lord and he spake unto me saying Joseph my son thy sins are forgiven thee." — Joseph Smith, History, ca. Summer 1832^[15]

The canonical 1838 account

In 1838, at Far West (Missouri), Joseph Smith dictated a new version, published in 1842 in Times and Seasons and canonized as Joseph Smith—History 1 in the Pearl of Great Price. This time, two divine personages appear — the Father and the Son — and the question asked is no longer that of forgiveness, but that of which church to join:

"When the light rested upon me I saw two Personages, whose brightness and glory defy all description, standing above me in the air. One of them spake unto me, calling me by name and said, pointing to the other—This is My Beloved Son. Hear Him!" — Joseph Smith, Joseph Smith—History 1:17 (canonical, dictated in 1838)^[16]

To the question of which church to join, the Father is said to have answered:

"I was answered that I must join none of them, for they were all wrong; and the Personage who addressed me said that all their creeds were an abomination in his sight; that those professors were all corrupt." — Joseph Smith—History 1:19^[17]

How the LDS Church justifies these divergences today

The Gospel Topics Essay published in 2013 acknowledges the existence of at least nine distinct accounts (four primary plus five secondary) and compares the variations to the multiple accounts of Saint Paul's conversion at Damascus^[18]. The comparison is apologetically clever, but it conceals an important point: in the Acts of the Apostles, the three accounts appear in the same book (Acts 9; 22; 26), with no contradiction about the actors; in Smith's case, the gap is eighteen years, and even the number of divine personages varies.

For a faithful Latter-day Saint, the First Vision is the most important event of modern history. For an attentive historian, the evolution of the narrative poses a problem: the most solemn, most precise and most canonical version is also the latest.

The stone in the hat

Joseph Smith claimed to have received from the angel Moroni, in 1827, on a hill called Cumorah near Manchester (NY), a set of golden plates engraved in "reformed Egyptian", containing the religious history of ancient Hebrews who migrated to America between 600 BC and AD 421. He is said to have translated their content within a few months, by means of the "Urim and Thummim" — two prophetic stones set in a breastplate mount — then published the result on March 26, 1830, under the title The Book of Mormon.

For more than a century and a half, the Church's official iconography depicted Joseph Smith seated at a table, the golden plates before him, reading through the Urim and Thummim spectacles. Yet in 2013, the Church published a Gospel Topics Essay that officially acknowledges a very different method:

"Joseph placed either the interpreters or the seer stone in a hat, pressed his face into the hat to block out light, and read aloud the English words that appeared on the instrument." — Gospel Topics Essay, Book of Mormon Translation, 2013^[19]

The testimony of Emma Smith, the prophet's wife, is reproduced in the same essay:

"He sat with his face buried in his hat, with the stone in it, and dictated hour after hour with nothing between us." — Emma Smith, testimony quoted in the Gospel Topics Essay^[20]

The stone used is exactly the same one Joseph Smith employed in his pre-prophetic treasure-seeking years. For historical criticism, this is a massive fact; for the LDS defense, it is an occasion to stress that the method matters less than the result. But the gulf between the received iconography and the reality dictated by Emma herself points to a presentational effort that the Church itself ended up correcting.

The Mormon canon: four books held as Scripture

The Latter-day Saints recognize four books as inspired Scripture:

The Bible is therefore neither the sole normative book nor the principal book. The 8th Mormon Article of Faith states: "We believe the Bible to be the word of God as far as it is translated correctly", which opens the door to revisions — carried out by Joseph Smith himself in his Joseph Smith Translation — to make the Bible compatible with LDS doctrine.

Added to this is the principle of continuing revelation: the president of the Church, regarded as a "prophet, seer and revelator", may in theory receive revelations with normative force, as Wilford Woodruff did in 1890 in ending polygamy, or Spencer W. Kimball in 1978 in opening the priesthood to Black members.

Between 1830 and 1844, the young Church founded at Fayette (NY, according to LDS sources) wandered from one state to another, hounded by conflicts with neighbors, defections among its own leaders, and Joseph Smith's growing political ambitions.

The Carthage Jail episode is foundational for Mormon identity: Joseph Smith dies there as a martyr, sealing his prophetic authority for posterity. The traditional narrative stresses prayer and hymn-singing; historiography now acknowledges — including in the landmark LDS biography by Richard L. Bushman — that Smith was armed with a revolver brought in by a visitor, and that he used it before being shot^[22]. The martyrdom is not invented, but the context is more complex than the golden legend.

A revelation kept hidden for eight years

The most controversial doctrine of early Mormonism was not revealed in the open. Joseph Smith practiced polygamy from the 1830s (first presumed plural marriage: Fanny Alger, 1833, about 16 years old). The "revelation" codifying the practice — section 132 of the Doctrine and Covenants — was dictated at Nauvoo on July 12, 1843, to the scribe William Clayton. It orders Emma Smith to accept plural wives:

"And let mine handmaid, Emma Smith, receive all those that have been given unto my servant Joseph […]. But if she will not abide this commandment she shall be destroyed, saith the Lord; for I am the Lord thy God, and will destroy her if she abide not in my law." — Doctrine and Covenants 132:52^[23]

During the eight years separating the first clandestine marriages from the written revelation, Joseph Smith publicly denied the practice while secretly teaching it to a restricted circle of believers, mainly through the "Quorum of the Anointed" formed in 1842. The LDS historian Linda King Newell and her collaborator Valeen Tippetts Avery, in their biography of Emma Smith, speak of a system of "code words" intended to conceal the doctrine from the public — and from Emma herself^[24].

How many wives?

The LDS Church officially acknowledges, in a Gospel Topics Essay published in 2014, that Joseph Smith was sealed to between 30 and 40 wives^[25]. The range includes:

• young women, including Helen Mar Kimball (born August 22, 1828), sealed to Joseph in May 1843, at 14 — a few months before her 15th birthday — when Joseph was 37^[26];
• older women such as Fanny Young (56);
• at least twelve to fourteen women already married to another man at the time of the sealing to Joseph (polyandry is thus documented by Bushman himself)^[27].

The official essay admits the contemporary moral difficulty:

"Marriage at such a young age, though inappropriate by today's standards, was legal in that era." — Gospel Topics Essay, Plural Marriage in Kirtland and Nauvoo, 2014^[28]

The "it was legal at the time" argument is honest historically but does not answer the doctrinal question: if polygamy was a divine revelation of universal application, how could it have been abandoned in 1890 by a mere Manifesto? And if it is eternally true (D&C 132 remains canonical), why no longer practice it?

The double Manifesto: 1890 and 1904

Under growing pressure from the United States federal government — which adopted increasingly harsh anti-polygamy legislation (Edmunds Act 1882, Edmunds-Tucker Act 1887, legal dissolution of the LDS Church corporation and confiscation of its property) — the fourth president of the Church, Wilford Woodruff, published on September 25, 1890, "Official Declaration 1" (or "Manifesto") announcing the end of the teaching and practice of polygamy. But the Church itself now acknowledges that, according to a non-exhaustive register of marriages and sealings performed outside the temple, 315 marriages were performed between October 17, 1890 and September 8, 1903, of which only 25 were plural (7.9%, the other 290 being monogamous)^[29] — mostly in Mexico and the American West.

A Second Manifesto was needed in 1904, under Joseph F. Smith, to impose excommunication on offenders. For fourteen years, the Church thus continued to practice what it claimed to have abolished. To this day, fundamentalist groups claiming Joseph Smith's legacy continue polygamy, regarded by the official Church as grounds for excommunication.

A 126-year ban

From 1852 to 1978, Black men of African descent were barred from the Mormon priesthood, and men and women alike were excluded from temple ordinances (endowment, sealing). This policy was publicly announced by Brigham Young in 1852, doctrinally justified by references to the "curse of Cain" and an alleged "lack of valiance" in premortal life. It remained in force until "Official Declaration 2" promulgated by Spencer W. Kimball on June 9, 1978.

The 2013 turnaround

In an official essay published in 2013 — one of the rare documents in which the Church openly disavows an earlier teaching of its prophets — the institution states:

"Today, the Church disavows the theories advanced in the past that black skin is a sign of divine disfavor or curse, or that it reflects unrighteous actions in a premortal life; that mixed-race marriages are a sin; or that blacks or people of any other race or ethnicity are inferior in any way to anyone else." — Gospel Topics Essay, Race and the Priesthood, 2013^[30]

This disavowal is honest. It does, however, raise a grave doctrinal question: if Brigham Young, second president and prophet of the Church, could have advanced a false racial theory in God's name for 126 years, what guarantees that the other prophetic teachings are themselves true? Mormonism rests on the idea that the living prophet cannot lead the Church astray (Wilford Woodruff, 1890 Manifesto: "The Lord will never permit me or any other man who stands as President of this Church to lead you astray"^[31]). The race episode is a major crack in this postulate.

A corporeal, finite, exalted God

The LDS doctrine of God breaks head-on with the Trinitarian and Christian tradition. The clearest source is the King Follett Discourse, delivered by Joseph Smith on April 7, 1844 — two and a half months before his death — before 20,000 people at a funeral conference at Nauvoo.^[32]

"God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens! […] If you were to see him today, you would see him like a man in form—like yourselves, in all the person, image, and very form as a man." — Joseph Smith, King Follett Discourse, April 7, 1844^[33]

"You have got to learn how to be Gods yourselves, and to be kings and priests to God, the same as all Gods have done before you—namely, by going from one small degree to another […] until you attain to the station of a God." — Joseph Smith, King Follett Discourse^[34]

The fifth president of the Church, Lorenzo Snow, summed up this doctrine in a famous couplet, still taught today:

"As man now is, God once was; as God now is, man may be." — Lorenzo Snow, biography by Eliza R. Snow, 1884^[35]

The corporeal character of God is canonized in the Doctrine and Covenants:

"The Father has a body of flesh and bones as tangible as man's; the Son also; but the Holy Ghost has not a body of flesh and bones, but is a personage of Spirit." — Doctrine and Covenants 130:22^[36]

The official 2014 essay Becoming Like God confirms this doctrine of literal deification:

"Latter-day Saints see all people as children of God in a full and complete sense; they consider every person as divine in origin, nature, and potential eternal destiny." — Gospel Topics Essay, Becoming Like God, 2014^[37]

The "Heavenly Mother" and divine parents

Mormon cosmology introduces a divine personage absent from all biblical Scripture: the Heavenly Mother. The 2015 Gospel Topics Essay states:

"All human beings—male and female—are created in the image of God. Each is a beloved spirit son or daughter of heavenly parents, and, as such, each has a divine nature and destiny." — Gospel Topics Essay, Mother in Heaven, 2015^[38]

This doctrine implies that procreation extends into the divine nature itself: God the Father spiritually begot His children in union with a Heavenly Mother. Catholic theology does not deny God's fatherhood (CCC §239); it only refuses to understand it in the sense of a bodily procreation. The Heavenly Mother, attested nowhere in the Bible or in apostolic Tradition, is one of the points where Mormon doctrine displays its internal coherence at the cost of maximum distance from historical Christianity.

The "Godhead": three gods united in purpose

It is on this point that the doctrinal divergence is sharpest and most decisive for the invalidity of baptism pronounced by Rome. Mormonism affirms the existence of the Father, the Son and the Holy Spirit, but as three distinct beings:

• The Father has a body of flesh and bones.
• The Son, Jesus, also has a body of flesh and bones; He is the "elder brother" of all human spirits, including Lucifer, in the premortal council.
• The Holy Spirit is "a personage of spirit" without a physical body.

Their unity is not of essence but of purpose: three gods cooperating. The Godhead begins to exist, in the LDS system, from the moment the three Persons decided to unite to work for man's salvation. This is exactly what Fr. Ladaria sums up in the official commentary on the 2001 Responsum:

"For the Mormons, the Father, the Son and the Holy Spirit are not the three persons in whom subsists the one Godhead, but three gods who form one divinity. The very word divinity has only a functional, not a substantial content, because the divinity originates when the three gods decided to unite and form the divinity to bring about human salvation." — Fr. Luis Ladaria, S.J., official commentary on the Responsum, L'Osservatore Romano, August 1, 2001^[39]

The pre-existence of spirits and the premortal council

Every human being, in LDS doctrine, pre-exists as a "spirit" before earthly birth, in a premortal life spent with the heavenly parents. This doctrine is canonized in the Book of Abraham (Pearl of Great Price):

"Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the noble and great ones." — Abraham 3:22 (Pearl of Great Price)^[40]

Before the creation of the earth, a premortal council is held during which two sons of the Father propose their plans: Jesus offers to serve the Father's will; Lucifer offers to eliminate free agency and "save" everyone while demanding the glory for himself. A third of the spirits follow Lucifer and are cast out of heaven; they become the demons. The remaining spirits receive a mortal body on earth^[41].

This doctrine profoundly alters Christian anthropology. Humans are not, as in the Catholic account, created ex nihilo by God at a given moment of their conception; they are eternal intelligences organized into spirits and then incarnated. Christ Himself is, in this system, the elder brother of humans and of Lucifer — not the eternal Word consubstantial with the Father.

The three degrees of glory

Mormonism replaces the traditional doctrine of "heaven, purgatory, hell" with three degrees of glory revealed to Joseph Smith on February 16, 1832, in a vision recorded in Doctrine and Covenants 76. Only a tiny minority (the "sons of perdition") know outer darkness; almost everyone is saved in one of the three kingdoms:

Exaltation — that is, full deification — is reserved for those who, in the celestial kingdom, have received all the temple ordinances, in particular the sealing of marriage for eternity. The central verse is Doctrine and Covenants 132:20:

"Then shall they be gods, because they have no end; therefore shall they be from everlasting to everlasting, because they continue; then shall they be above all, because all things are subject unto them. Then shall they be gods, because they have all power, and the angels are subject unto them." — Doctrine and Covenants 132:20^[42]

Temple ordinances

Mormon temples are not ordinary places of worship. They are places closed to non-members and even to "unworthy" Mormons (who must obtain a "recommend" to enter), reserved for the following sacred ordinances:

• Baptism for the dead — by proxy, in a font mounted on twelve bronze oxen (echoing the bronze sea of Solomon's temple). Justified by 1 Corinthians 15:29.
• The endowment — a ceremony lasting several hours including an investiture ritual with priestly garments, symbolic instruction on creation, the fall and redemption, and oaths of obedience.
• Sealing — marriage performed "for time and for all eternity", distinct from Mormon civil marriage. Sealing makes family life possible in the resurrection and is the condition of exaltation.

Proxy baptism is a practice unique to contemporary Mormonism. The LDS Church carries on massive genealogical activity (the FamilySearch website is one of the world's largest genealogical databases) precisely because every deceased person must be able to be baptized by proxy by a living person. This is what prompted the letter of April 5, 2008 by which the Congregation for the Clergy asked episcopal conferences to forbid sharing parish registers with Mormon missionaries — an internal letter known only through the Catholic News Service dispatch and the Archdiocese of Baltimore statement relaying it^[43].

Two priesthoods and the living prophet

Mormonism claims to have restored, by revelation to Joseph Smith and Oliver Cowdery, two priesthoods lost since the general apostasy:

• The Aaronic Priesthood, or Levitical priesthood, restored by John the Baptist appearing in person to Smith and Cowdery on May 15, 1829, on the banks of the Susquehanna; it confers the right to administer baptism.
• The Melchizedek Priesthood, restored by Peter, James and John appearing shortly after; it confers all spiritual powers.

Every male member of the Church, from the age of twelve, is ordained to an office (deacon, teacher, priest, elder, high priest, seventy, apostle). The supreme hierarchy comprises the First Presidency (president + two counselors), the Quorum of the Twelve Apostles and several Quorums of the Seventy. The president is regarded as a "prophet, seer and revelator" for the whole Church and may in theory receive canonical revelations.

The Book of Abraham papyri

The Book of Abraham is a canonical Mormon text first published in 1842 in Times and Seasons, then incorporated into the Pearl of Great Price in 1851. Joseph Smith claimed to have "translated" it from Egyptian papyri bought in July 1835 from Michael Chandler along with four mummies. Smith described these papyri as "the writings of Abraham while he was in Egypt".

For 130 years, the papyri themselves were presumed lost in the 1871 Chicago fire. On November 27, 1966, Professor Aziz S. Atiya, a Byzantinist at the University of Utah, identified part of the original papyri in the storerooms of New York's Metropolitan Museum of Art. They were returned to the LDS Church on November 27, 1967.

For the first time, the papyri could be compared with Smith's "translation". The verdict of Egyptologists, Mormon and non-Mormon alike, was immediate and unanimous:

"The Breathing Permit belonging to the priest Hor […] Joseph Smith thought that this papyrus contained the Book of Abraham. […] The handwriting is of the late Ptolemaic or early Roman Period, about the time of Christ." — Klaus Baer, The Breathing Permit of Hor, Dialogue: A Journal of Mormon Thought 3/3, 1968, p. 111^[44]

The actual Egyptian text is therefore:

1. A standard Osirian funerary ritual, dated to about 50 BC — more than 1,500 years after Abraham.
2. Written for a Theban priest named Hor, not by Abraham.
3. No name of Abraham appears in it.

The Egyptologist Robert K. Ritner, professor at the University of Chicago's Oriental Institute, in his complete critical edition of the papyri published in 2011, concludes:

"The source of the Book of Abraham is the 'Breathing Permit of Hôr,' misunderstood and mistranslated by Joseph Smith. […] The Book of Abraham is confirmed as a perhaps well-meaning, but erroneous invention by Joseph Smith." — Robert K. Ritner, The Joseph Smith Egyptian Papyri: A Complete Edition, Smith-Pettit Foundation, 2011^[45]

The Church's official 2014 response

Faced with a case impossible to deny, the LDS Church published in 2014 a Gospel Topics Essay that acknowledges the facts while proposing two escape routes:

"None of the characters on the fragments match the translation given in the book of Abraham. […] Mormon and non-Mormon Egyptologists agree that the characters on the fragments do not match the translation given in the book of Abraham, though there is not consensus about the reason for the disparity." — Gospel Topics Essay, Translation and Historicity of the Book of Abraham, 2014^[46]

The two explanations proposed by the essay are:

1. The missing papyri: most of the scrolls are said to be lost; the translation is said to concern leaves not among the fragments recovered at the Met.
2. Translation by revelation: the papyri are said to have served as an "occasion for meditation"; Smith is said to have received the text of Abraham directly by revelation, with no linguistic connection to the hieroglyphs.

The first hypothesis is invalidated by the contemporary testimony of Smith himself, who claimed to be translating the exact characters. The second reduces "translation" to a pious literary fiction, which would empty the whole concept of "inspired scripture". On this case as on that of the Book of Mormon, the difficulty is all the more acute in that the Church itself ended up conceding the central facts.

The unfindable archaeology of the Book of Mormon

The Book of Mormon tells the story of three great migrations of Semites to America:

1. The Jaredites (around 2200 BC, Babel dispersion).
2. The Nephites and Lamanites (around 600 BC, departure from Jerusalem under Lehi).
3. The Mulekites (people of Mulek, son of Zedekiah).

These peoples are said to have built fortified cities, minted coins, raised cattle, wielded steel swords, chariots and armor. A great final battle, at Cumorah (NY), is said to have killed 230,000 Nephites in a few days, around AD 385^[47].

Yet nothing has ever been found. The Yale Mayanist Michael D. Coe, in a 1973 article in the Mormon journal Dialogue — thus addressed to an LDS readership — sums up the situation:

"The bare facts of the matter are that nothing, absolutely nothing, has ever shown up in any New World excavation which would suggest to a dispassionate observer that the Book of Mormon, as claimed by Joseph Smith, is a historical document relating to the history of early migrants to our hemisphere." — Michael D. Coe, Mormons and Archaeology: An Outside View, Dialogue 8/2, 1973^[48]

"Let me now state uncategorically that as far as I know there is not one professionally trained archaeologist, who is not a Mormon, who sees any scientific justification for believing the foregoing to be true." — Michael D. Coe, ibid.^[49]

The Smithsonian Institution itself, in its official 1996 statement, lists the scientifically verified anachronisms of the Book of Mormon: the absence before 1492 of horses, donkeys, cattle, pigs, goats, camels, wheat, barley, iron, steel, glass and silk in pre-Columbian America^[50]. All things nevertheless mentioned in the Book of Mormon as characteristic of Nephite civilization.

Native American DNA: Asian, not Semitic

Since the mapping of the human genome and the generalization of mitochondrial marker sequencing, the origin of Native American peoples is now clearly established: they descend from Siberian populations that crossed the Bering Strait during the last ice age. Native American mitochondrial haplogroups (A, B, C, D, X) are Asian, and the total absence of pre-Columbian Semitic DNA is admitted by the entire scientific community.

The LDS Church in turn admits it, in 2014:

"DNA studies cannot be used decisively to either affirm or reject the historical authenticity of the Book of Mormon. […] The evidence assembled to date suggests that the majority of Native Americans carry largely Asian DNA." — Gospel Topics Essay, Book of Mormon and DNA Studies, 2014^[51]

The introduction to the Book of Mormon was changed in 2006: the Lehite peoples are now described as among the ancestors of Native Americans, no longer as their principal ancestors^[52]. The Mormon scientist Simon G. Southerton, a former LDS bishop and molecular biologist at the Australian CSIRO, documented in Losing a Lost Tribe (2004) the insurmountable contradiction between the scriptural claim and the genetic data. He was excommunicated shortly after publication^[53].

Dependence on the King James Version

The Book of Mormon contains over 200 passages copied word for word from the King James Version (King James Bible, 1611), the 17th-century English translation. More precisely:

• Entire chapters of Isaiah are reproduced in 2 Nephi with the italics of the King James — yet these italics mark words added by the English translators to render the sense where no Hebrew equivalent existed. Their presence in a text "translated" from a 600 BC Hebrew original is inexplicable.
• The Book of Mormon reproduces in Ether 4:18 and Mormon 9:22-24 the long ending of Mark (Mk 16:9-20), absent from the oldest Greek manuscripts and widely recognized by textual criticism as a post-2nd-century addition. A Nephite text completed in the 4th century could not have quoted an addition the Greek Church did not yet know in that wording.

These features are compatible with a single historical hypothesis: the Book of Mormon was composed in English, in the 19th century, by someone with the King James on his table.

The eleven witnesses and the missing plates

The LDS Church usually produces the statements of Three Witnesses (Oliver Cowdery, David Whitmer, Martin Harris) and Eight Witnesses as evidence of the golden plates' existence. Two facts remain to be stated:

1. All Three Witnesses left the Church between 1837 and 1838; Cowdery and Harris were later rebaptized, but David Whitmer never returned and founded his own dissident church.
2. According to a letter from Stephen Burnett — then breaking with the Church — Martin Harris is said to have publicly stated, at an Ohio gathering in 1838, that he had "never seen the plates with his natural eyes, but only in vision or imagination"^[54].
3. The Eight Witnesses are all members of the Whitmer and Smith families — so the testimony is not independent.

Joseph Smith refused all his life to produce the plates for outside examination. According to the narrative, the angel Moroni took them back before the book's publication. No trace, no fragment, no photograph exists.

View of the Hebrews and the B.H. Roberts hypothesis

In 1823 — seven years before the publication of the Book of Mormon — a Congregationalist minister of Poultney (Vermont), Ethan Smith, published a book entitled View of the Hebrews; or the Tribes of Israel in America. The work defended the then-popular thesis of an Israelite origin of Native Americans, descended from the ten lost tribes. It was reissued in 1825 in an expanded version. The principal scribe of the Book of Mormon, Oliver Cowdery, lived in Poultney (Vermont) until 1825, where his mother-in-law and three of his sisters attended Ethan Smith's Congregationalist church.

In the 1920s, the Mormon apologist B. H. Roberts — a member of the First Council of the Seventy, a respected intellectual — undertook a systematic comparison of the two books and wrote a 291-page manuscript (A Book of Mormon Study), accompanied by a synoptic comparison in eighteen "parallels" between View of the Hebrews and The Book of Mormon. Published posthumously in 1985 by the University of Illinois Press under the title Studies of the Book of Mormon, this work from inside the Church does not deny faith in the Book of Mormon's authority, but acknowledges that the thesis of a purely literary origin cannot easily be dismissed.

One God, simple, immutable, incorporeal

The Catholic doctrine of God, formulated by seven ecumenical councils, is the exact opposite of Mormon doctrine on every one of its points. The Fourth Lateran Council, in 1215, formulated it with a clarity that makes any confusion impossible:

"We firmly believe and simply confess that there is one true God alone, eternal, immense, omnipotent, immutable, incomprehensible and ineffable, Father and Son and Holy Spirit: three Persons indeed, but one essence, substance or nature entirely simple." — Fourth Lateran Council (1215), constitution Firmiter credimus, Denzinger 800^[55]

The First Vatican Council, in 1870, in its dogmatic constitution Dei Filius, spelled out the doctrine in terms that refute Mormon doctrine point by point:

"The holy Catholic apostolic Roman Church believes and confesses that there is one true living God, Creator and Lord of heaven and earth, omnipotent, eternal, immense, incomprehensible, infinite in intelligence, in will and in all perfection; who, being one singular, entirely simple and immutable spiritual substance, must be proclaimed really and essentially distinct from the world, perfectly happy in and of Himself, and ineffably exalted above all that exists or can be conceived besides Him." — First Vatican Council (1870), Dei Filius, ch. 1, Denzinger 3001^[56]

Each qualifier refutes a central point of Mormon cosmology:

The Catechism of the Catholic Church, quoting Lateran IV, concludes:

"The Trinity is One. We do not confess three Gods, but one God in three Persons: the 'consubstantial Trinity.'" — Catechism of the Catholic Church, § 253^[57]

One Christ, true God and true man

If God the Father is an exalted man and Jesus His pre-existing brother, then Mormon Christology overturns the mystery of the Incarnation. For the Christian faith, Christ is not a being who acquires divinity by merit or progression: He is God from all eternity, begotten not made, consubstantial with the Father. That is the very meaning of the word homoousios inscribed at the heart of the Nicene Creed in 325:

"[We believe] in one Lord Jesus Christ […], begotten, not made, of one substance with the Father (homoousion to Patri), by whom all things were made. […] As for those who say: There was a time when he was not, or: Before being begotten he was not […], the Catholic and apostolic Church anathematizes them." — First Council of Nicaea (325), creed, Denzinger 125-126^[58]

The Council of Chalcedon (451) spelled out the union of the two natures in one Person, in a formula that became the ecumenical Christian standard:

"We unanimously teach that one and the same Son, our Lord Jesus Christ, is to be confessed, the same perfect in divinity and perfect in humanity, the same truly God and truly man […], consubstantial with the Father according to divinity, and the same consubstantial with us according to humanity […], acknowledged in two natures, without confusion, without change, without division, without separation." — Council of Chalcedon (451), Denzinger 301-302^[59]

To say that Jesus is our "elder brother" and that He shared the same premortal origin as Lucifer is to say that He is not God from all eternity. That is exactly the position of the Arianism fought by Saint Athanasius and condemned at Nicaea — in a new, Mormonized form.

Revelation is closed with Christ

Mormonism relies on the principle of continuing revelation: the living prophet may receive new normative Scriptures, as Joseph Smith received D&C, Abraham and Moses. This claim directly offends the Catholic faith. The Second Vatican Council, in the dogmatic constitution Dei Verbum, restated it plainly:

"The Christian economy, being the new and definitive covenant, will never pass away; and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ." — Second Vatican Council, Dei Verbum § 4 (November 18, 1965)^[60]

The Catechism of the Catholic Church comments:

"Christ, the Son of God made man, is the Father's one, perfect and unsurpassable Word. In him he has said everything, and there will be no other word than this one." — Catechism of the Catholic Church, § 65^[61]

"Throughout the ages, there have been so-called 'private' revelations, some of which have been recognized by the authority of the Church. […] It is not their role to 'improve' or to 'complete' Christ's definitive Revelation, but to help live more fully by it in a certain period of history." — Catechism of the Catholic Church, § 67^[62]

Lourdes, Fatima, Guadalupe are private revelations: they confirm the Gospel, do not complete it, and impose no new faith on anyone. The Book of Mormon, by contrast, is presented as "the fulness of the everlasting Gospel" that completes and corrects the Bible. This claim frontally contradicts the definitive character of Revelation in Christ.

The visible Church that Christ does not abandon

The pivot of the Mormon system is the doctrine of the great apostasy: the Church founded by Christ is said to have vanished from the earth upon the apostles' death, corrupted by Greek philosophy and deprived of the priesthood, until its restoration by Joseph Smith in 1830. The Catholic faith answers that this thesis is impossible for three converging reasons.

The scriptural argument

Christ Himself promised:

"You are Peter, and on this rock I will build my Church, and the gates of Hades will not prevail against it." — Gospel according to Saint Matthew 16:18

If the Church was effectively destroyed for 1,700 years, Christ was mistaken, or He lied, or the "gates of hell" overcame His Church. Every hypothesis is destructive of the faith.

The historical argument

Christian history shows no disappearance. It shows a visible continuity: unbroken succession of the bishops of Rome since Saint Peter, succession of the bishops of all the apostolic churches, ecumenical councils from Nicaea to Chalcedon, continuous sacramental life, a multitude of saints, martyrs, doctors, mystics. Apostolicity is not a claim; it is a documentable fact.

The ecclesiological argument (Vatican II)

The Second Vatican Council, in the constitution Lumen Gentium, confessed:

"This Church, constituted and organized as a society in the present world, subsists in (subsistit in) the Catholic Church, which is governed by the successor of Peter and by the bishops in communion with him." — Second Vatican Council, Lumen Gentium § 8 (November 21, 1964)^[63]

The subsistit in does not deny that elements of sanctification exist outside full Catholic communion, in the other Christian communities. But it affirms that no "new restored Church" has yet to come: the Church of Christ exists, it subsists, it is visible. The Mormon claim of a plenary restoration in 1830 is, for the Catholic, simply unintelligible.

A Responsum in one word

On June 5, 2001, the Congregation for the Doctrine of the Faith (renamed the Dicastery for the Doctrine of the Faith in 2022), answering a question raised notably by the United States conference of bishops, published a Responsum whose concision is ascetic:

Question: "Whether the baptism conferred by the community 'The Church of Jesus Christ of Latter-day Saints', commonly called 'Mormons', is valid."

Answer: "Negative."

— Congregation for the Doctrine of the Faith, Responsum ad propositum dubium, June 5, 2001, signed Joseph Cardinal Ratzinger and Tarcisio Bertone, approved by Pope John Paul II on June 5, 2001, published in Acta Apostolicae Sedis 93 [2001] 476^[64]

It is one of the driest and most precise acts of the contemporary Magisterium. Its doctrinal scope is immense: almost all Protestant baptisms are recognized as valid by the Catholic Church (except baptisms not respecting the essential matter and form), but that of the Mormons is not.

The commentary of the future Cardinal Ladaria

A few weeks later, L'Osservatore Romano published an official commentary signed by Fr. Luis F. Ladaria, S.J., then professor of dogmatic theology at the Gregorian University and consultor of the CDF — he would become its secretary only in 2008, then prefect in 2017 and cardinal in 2018. This commentary explains the four reasons for invalidity.

The form: deceptive resemblance

The Mormon baptismal formula ("Having been commissioned of Jesus Christ, I baptize you in the name of the Father, and of the Son, and of the Holy Ghost") uses the same words as the Christian Trinitarian formula. But they are the same words used in a radically different sense, because the names of the Father, the Son and the Holy Spirit do not designate for Mormons the three Persons in whom the one Divinity subsists, but three ontologically distinct gods.

The intention: doing something else

For a baptism to be valid, the minister must have the intention of doing what the Church does. Yet the Mormon minister intends to do what his Church does — which is not the same thing as what the Church of Christ does. The intention is therefore objectively skewed by doctrine.

The minister: without the apostolic priesthood

The Mormon minister claims to act under the authority of a "restored priesthood" that has no link of apostolic succession with the Christian priesthood. The Mormon Aaronic and Melchizedek priesthood, claimed to have been restored to Joseph Smith in 1829, is a new priesthood, with no continuity with the apostles' laying on of hands.

The underlying doctrine: a foreign religion

This is the decisive point. Fr. Ladaria writes:

"One cannot even consider that this doctrine is a heresy which emerged out of a false understanding of the Christian doctrine." — Fr. Luis Ladaria, S.J., official commentary on the Responsum, L'Osservatore Romano, August 1, 2001^[65]

This sentence is rarely noticed. Yet it is crucial. Mormonism is not a Christian heresy (like Arianism, or Nestorianism, or even Protestantism). It is a distinct religious system that uses a Christian vocabulary to express a new faith. The difference is not of degree but of nature.

Practical canonical consequences

The complementary commentary of Msgr. Urbano Navarrete, S.J. spells out the canonical consequences. A Mormon asking to enter the full communion of the Catholic Church must be treated as a catechumen, not as a separated Christian. He receives the sacrament of baptism, not a mere profession of faith. Marriage between a Catholic and a Mormon is subject to the impediment of disparity of cult (cf. canon 1086), and requires not a mere permission but an episcopal dispensation for the marriage's validity^[66].

A second decision in 2008

Seven years later, on April 5, 2008, the Congregation for the Clergy sent the world's episcopal conferences a letter (internal, unpublished in the AAS, known through the Archdiocese of Baltimore's relay^[67]) asking that parish registers no longer be shared with Mormon missionaries. The justification is twofold: to protect the confidentiality owed to the faithful, and not to cooperate indirectly in the practice of proxy baptism of the dead, deemed unacceptable^[68]. The letter seals a clear policy: genealogical cooperation with the LDS Church, even for apparently neutral motives, must not serve to extend to deceased Catholics a Mormon rite the Church regards as devoid of sacramental value.

In the broad sociological sense

In the sociological sense, the Latter-day Saints are undeniably attached to the person of Jesus Christ. The name "Church of Jesus Christ" is in the official title; every weekly service commemorates the Savior's death; missionaries greet in Jesus' name. Many sincere Mormons live a demanding family morality, refuse alcohol, tobacco and pornography, pay their tithing, and bear a testimony of faith sometimes more ardent than that of many nominal Catholics.

In the sense in which being "Christian" means subjectively loving Jesus, yes, many are.

In the doctrinal sense of the Creeds

But the word "Christian", in history, designates a specific faith, formulated in the ecumenical Creeds of Nicaea and Constantinople, namely: one Triune God, one Christ true God and true man, one visible and apostolic Church, one baptism in the name of the Father and of the Son and of the Holy Spirit, one Revelation accomplished in Jesus Christ. In that sense — the historical and doctrinal sense of the word — Mormonism is not a Christian confession.

This distinction is not contempt: it is what makes it possible to respect both Mormons and the historical truth of the word "Christian". Presenting Mormonism as a mere variant of Christianity would amount to abolishing seventeen centuries of ecumenical debate and emptying words of their meaning.

A missionary religion from America

The historian of religions Harold Bloom, in The American Religion (1992), wrote one of the most penetrating analyses of Mormonism. For Bloom — who is neither Catholic nor Mormon — Mormonism is what most resembles, in modern history, a new great religion, comparable in its originality and internal coherence to Islam in the 7th century rather than to a Protestant reform^[69]. Bloom sees in Joseph Smith "an authentic religious genius", which does not oblige us to follow him, but which helps us understand why the rupture runs so deep: we are not facing a Christian schism, we are facing a new religion.

Many Catholics meet Mormons in the form of missionaries in white shirts, young adults sent two years into the world to bear witness. How to dialogue with them without hostility or naivety?

Three doors in

1. Who is Jesus? The most important conversation is not about the Book of Mormon; it is about Christ. Is the Christian Jesus — eternal Word, consubstantial with the Father, God from all eternity — the Mormon Jesus — elder brother of humans, created before the foundation of the world, ontologically distinct from the Father? This question leads straight to the Trinitarian and Chalcedonian question. Saint Athanasius wrote in the 4th century in De Incarnatione: "For He was made man that we might be made God."^[70] But the Christian "becoming God" is a participation in the divine nature by grace, in Christ (cf. 2 Peter 1:4), not becoming another god exalted alongside God.

2. Is Revelation closed or open? Saint Paul writes to the Galatians: "But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we preached to you, let him be accursed" (Galatians 1:8). What criterion distinguishes a true revelation from a false one? The Catholic Church answers: fidelity to the Gospel received from the apostles. Any alleged revelation that contradicts or completes the Gospel, and presents another God, another Christ, another Church, is to be rejected.

3. Did the Church really disappear for 1,700 years? If so, Christ failed. If not, the Mormon claim of a plenary restoration is pointless. The visible continuity of the Catholic Church since Peter — twenty centuries of popes, councils, saints, sacraments, martyrs — is the simplest factual refutation of the great-apostasy thesis.

The testimony of ex-Mormons turned Catholic

One of the most precious testimonies is that of Thomas W. Smith, a former LDS missionary converted to the Catholic faith^[71]. He told his journey on the Coming Home Network's The Journey Home program^[72]. His discovery was, he says, that of the Church Fathers: there he found the very teaching the LDS missionaries had presented to him as corrupted and lost. The Trinity, the Eucharist, the episcopate, prayer for the dead: all of it lived in the Christianity of the first two centuries, without rupture. The general apostasy, which he had been taught as obvious, had simply never happened.

What to avoid

• Mockery: mocking celestial marriage, sacred undergarments or the stone in the hat converts no one and wounds needlessly.
• The ad personam argument: Joseph Smith was a complex man; judging his religion by his faults is a shortcut. The doctrinal and historical arguments amply suffice.
• Verbal concession: saying "we believe the same thing, give or take a few details" is false and misleads the interlocutor. The difference is of nature, not of degree.
• Defensive retreat: a well-trained Mormon knows his Scriptures. A Catholic who wants to dialogue must have read a little — at minimum the Gospels, the Nicene Creed, and the Catechism on the Trinity and baptism.

Source: 2025 Statistical Report of The Church of Jesus Christ of Latter-day Saints, read at the April 2026 General Conference^[73].

The Salt Lake City Conference Center, home of this semiannual General Conference, was completed in 2000 and seats 21,000 in its main auditorium^[74].

Behind these official figures, the picture is more nuanced. The Pew Research Center, in its 2023-2024 Religious Landscape Study, reports that the retention rate of Latter-day Saints in the United States — the proportion of Mormon-raised children who remain Mormon as adults — has fallen from 70% in 2007 to 54% in 2023-2024^[75]. Nearly one cradle Mormon in two leaves the Church. The main cause is no longer, as in the 1970s-90s, outside social pressure (anti-Mormonism), but access to critical historical information via the Internet — the Gospel Topics Essays published from 2013 onward can be read as a response to this crisis.

The Church has reacted by multiplying temples (9 dedicated in 2025), simplifying missionary service and softening the tone of its public discourse toward classical Christianity. But it cannot renounce its founding doctrines on God, Christ and the priesthood without collapsing as a distinct religion. The tension between worldwide expansion and internal erosion is today the central issue of its history.

Mormons form a vigorous, missionary, morally structured religious community, deeply attached — in its own way — to the figure of Jesus Christ. This subjective attachment is respectable, and human encounter with a Latter-day Saint often reveals real family goodness, sincere faith, an ordered life.

But what the Catholic faith cannot concede is the illusion of doctrinal kinship where there is a new religion. The Mormon God is an exalted man of flesh and bones; the Catholic God is the one, simple, immutable Being, creator of heaven and earth. The Mormon Christ is the elder brother of human spirits; the Catholic Christ is the eternal Word consubstantial with the Father. Mormon Revelation opens with each generation through the voice of a living prophet; Catholic Revelation is complete in Jesus Christ. The Church of Christ has, according to Mormons, vanished for 1,700 years before being restored by Joseph Smith; according to the Catholic faith, it never vanished, because Christ promised it it would not.

On each of these points, the divergence is no detail. It touches who God is, who Christ is, what the Church is, what faith is. It is for this reason that the 2001 Responsum declared Mormon baptism invalid — not from distrust of persons, but from respect for the truth of words and the dignity of the sacrament.

The Catholic's duty, before a Latter-day Saint, is threefold: to love the person, to speak the truth, and to keep the hope that encounter with the true face of Christ — God truly God, man truly man — may one day lead this human brother into the full communion of the Church founded on Peter.

• The Trinity — one God in three Persons, consubstantial.
• The divinity of Jesus Christ — why Christ is not a secondary divine being.
• The Bible — canon, apostolic Tradition and the closing of public Revelation.
• Answers to Protestantism — sola scriptura and the Church's authority.
• Why Catholicism is the true religion — apostolicity and visible continuity.
• The First Council of Nicaea (325) — homoousios and the founding of Christological orthodoxy.
• The Council of Chalcedon (451) — two natures without confusion or division.
