Church of Christ vs. Mormon Beliefs

A Tale of Two Restorations: A Compassionate Guide to the Church of Christ and Latter-day Saint Beliefs

Why Are These Two Churches So Often Confused? A Look at Their Shared History

If you have ever felt confused by the similarities between the Church of Christ and The Church of Jesus Christ of Latter-day Saints (often called Mormons), you are not alone. This confusion is understandable because both groups grew from the same fertile soil of 19th-century American religious history, a period of intense spiritual revival known as the Second Great Awakening.¹ During this time, many Christians felt that the churches of their day had become too formal, divided, and distant from the simple faith they read about in the New Testament. This feeling gave rise to a powerful idea: “restoration”.³

Both the Church of Christ and the Latter-day Saints are fundamentally “restorationist” movements. They share the core belief that the original church founded by Jesus Christ fell into error and corruption—an “apostasy”—sometime after the first apostles died.⁵ They both believe it was necessary to restore the church to its pure, original form. But the way they went about this restoration created two vastly different faiths.

The Churches of Christ emerged from the Stone-Campbell Restoration Movement, led by men like Barton W. Stone and Alexander Campbell.³ Their method of restoration was to go back to the Bible and the Bible alone. They sought to strip away all human-made creeds, denominational names, and church hierarchies that were not explicitly found in the New Testament.⁸ Their guiding principle became a famous slogan: “Where the Bible speaks, we speak; where the Bible is silent, we are silent”.¹⁰ For them, restoring the church meant carefully following the biblical blueprint to reproduce the church as it was on the Day of Pentecost.⁸

The Church of Jesus Christ of Latter-day Saints began with a young man named Joseph Smith. His approach to restoration was not based on studying the Bible, but on receiving new, direct revelation from God.² According to his account, God the Father and Jesus Christ appeared to him in a vision and told him that all existing churches were “wrong” and that their creeds were an “abomination”.⁶ The LDS restoration was therefore built upon a foundation of new scripture, most notably the Book of Mormon, which Smith said he translated from ancient golden plates revealed to him by an angel.¹⁴ This restoration included the re-establishment of divine priesthood authority, which they believe had been lost from the earth during the “Great Apostasy”.⁵

The source of their restoration—one from a rigorous study of an ancient book, the other from a visionary experience and new books—is the fundamental fork in the road that explains every other difference between them. This shared desire for a pure, non-denominational church also explains why both groups initially called themselves the “Church of Christ”.⁸ They believed this was the simple, biblical name for God’s people, and using it was a way of declaring independence from what they saw as man-made divisions.⁸

Who Do They Say God Is? A Look at the Trinity vs. The Godhead

The most major and defining difference between the Church of Christ and the Latter-day Saints lies in their answer to the most fundamental question of faith: Who is God? Their answers are not just slightly different; they describe two entirely different beings and place them on opposite sides of a theological chasm that has defined orthodox Christianity for nearly 2,000 years.

The Churches of Christ hold to the historic, biblical doctrine of the Trinity.¹⁰ They believe in one God who exists eternally in three co-equal, co-eternal, and distinct Persons: God the Father, God the Son (Jesus Christ), and God the Holy Spirit.¹⁸ While they firmly believe in this doctrine, they often avoid using the word “Trinity” itself, because the term is not found in the Bible.¹⁰ This is a practical expression of their philosophy to “call Bible things by Bible names” and avoid what they see as non-biblical, philosophical terms.¹¹ But their

belief about the nature of God aligns with the orthodox understanding shared by Catholics, Protestants, and Orthodox Christians worldwide.

The Church of Jesus Christ of Latter-day in stark contrast, explicitly rejects the doctrine of the Trinity.² Their teaching, which stems directly from Joseph Smith’s “First Vision” of two separate personages, is that the Godhead is composed of three

separate and distinct beings.⁶ They teach that God the Father and Jesus Christ are two separate entities who have physical, glorified bodies of “flesh and bone,” while the Holy Ghost is a separate personage of spirit.⁶

When LDS scriptures say that the Father, Son, and Holy Ghost are “one,” it is interpreted to mean they are one in purpose, mind, and mission—like a perfectly unified team or committee—but not one in substance or being.²² This concept is further distinguished from historic Christianity by the LDS doctrine of “exaltation” or “eternal progression,” which teaches that God the Father was once a mortal man on another world and that worthy human beings can, through obedience to LDS teachings and covenants, progress to become gods themselves.²

This distinction is not a simple matter of semantics. The Church of Christ’s avoidance of the word “Trinity” is a matter of practice, while their doctrine of God is historically Christian. The LDS rejection of the Trinity is a foundational tenet of their entire faith. It redefines the very nature of God from the one, infinite, spiritual Being of the Bible to a council of separate, physical gods. This difference flows directly from their source of authority. The Church of Christ arrives at Trinitarianism through its study of the Bible. The Latter-day Saints arrive at their concept of the Godhead through the extra-biblical revelations of Joseph Smith. Therefore, any conversation about who God is will ultimately lead back to a more fundamental question: which authority is final?

Is the Bible Their Only Holy Book?

Flowing directly from their foundational claims about restoration and their understanding of God, the two groups have profoundly different views on sacred scripture. This difference centers on one key question: Is God’s written revelation to humanity finished, or is He still adding to it?

The Churches of Christ are a “people of the book”—and for them, that book is the Bible alone.⁹ They hold that the 66 books of the Protestant Bible, particularly the New Testament, are the complete, sole, and final authority for all matters of faith, doctrine, and church practice.⁸ They believe the canon of scripture is

closed, meaning that God is not giving new, binding, written revelation today, nor are there modern-day prophets with the same authority as the biblical apostles.¹⁷ In line with their restorationist principles, they reject all human creeds, confessions, and catechisms, not necessarily because of their content, but because they are seen as human additions that stand between the believer and the pure word of God.⁹

The Church of Jesus Christ of Latter-day by contrast, believes in an open canon of scripture.¹³ This means they believe God continues to reveal His will and word through living prophets, and these revelations can be added to the body of scripture. They have four primary scriptural texts, known as the “standard works” 13:

1. The Holy Bible: They use the King James Version and believe it to be the word of God, but with a crucial qualification: “as far as it is translated correctly”.²⁶ LDS theology teaches that over the centuries, “many plain and precious things” were removed from the Bible by a corrupt making it an incomplete and sometimes unreliable guide without the clarifying light of modern revelation.²⁶
2. The Book of Mormon: Subtitled “Another Testament of Jesus Christ,” this book is considered the keystone of their religion and is believed to be the “most correct of any book on earth”.¹³
3. The Doctrine and Covenants: This is a collection of modern revelations given primarily to Joseph Smith and his successors.¹³
4. The Pearl of Great Price: This book contains additional writings and translations from Joseph Smith, including his official history and his version of the books of Moses and Abraham.¹³

The LDS qualifier on the Bible’s accuracy—”as far as it is translated correctly”—is not primarily about linguistic translation from Hebrew or Greek. It is a theological statement that functionally subordinates the Bible to the other LDS scriptures and the teachings of their living prophet. In practice, this means that whenever a passage in the Bible appears to contradict the Book of Mormon or an LDS leader, the Bible is presumed to be the text in error.²⁶ This creates a clear hierarchy of authority: the living prophet is the highest authority, followed by the Book of Mormon and other LDS scriptures, with the Bible serving as a foundational but fallible witness.

This creates two entirely different ways of knowing what is true. For the Church of Christ, truth is found through a rational, text-based study of the Bible. A member will ask, “What does the Bible say?”.⁹ For a Latter-day Saint, truth is confirmed through a personal, spiritual feeling or “witness” that validates the teachings of the prophet and the Book of Mormon.²⁵ A member will ask, “What have you felt as you’ve prayed about it?” These two approaches to scripture create different religious worlds.

What Must I Do to Be Saved? A Look at Two Different Paths

When a person asks, “What must I do to be saved?”, the answers given by the Church of Christ and The Church of Jesus Christ of Latter-day Saints reveal core differences in their understanding of grace, obedience, and the ultimate goal of the Christian life. While both emphasize specific steps, the paths they lay out lead to very different destinations.

The Churches of Christ teach that salvation is a gift of God’s grace that is received by obeying a clear plan laid out in the New Testament.¹⁰ This is often presented as a sequence of five steps:

1. Hear the Gospel of Christ.²⁴
2. Believe in Jesus Christ as the Son of God.²⁴
3. Repent of past sins.²⁴
4. Confess faith in Jesus publicly.²⁴
5. Be Baptized by full immersion in water “for the remission of sins”.¹⁰

In their view, baptism is not merely a symbolic act or an outward sign of an inward change; it is the God-ordained moment when one’s sins are washed away and they are added to the church.⁸ They base this on a literal interpretation of passages like Acts 2:38, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins.” They also teach that it is possible for a baptized Christian to sin in such a way as to fall from grace and lose their salvation.¹⁰

For Latter-day the concept of “salvation” is more complex and has multiple meanings.²⁸

• General Salvation: This is salvation from physical death. Through Christ’s resurrection, everyone who has ever lived will be resurrected unconditionally, regardless of their personal righteousness.²⁸
• Individual Salvation: This is salvation from personal sin. It is conditional and requires faith in Jesus Christ, repentance, baptism by proper priesthood authority, and receiving the gift of the Holy Ghost. This salvation must be maintained by a lifetime of obedience to God’s commandments, a principle they call “enduring to the end”.²⁸
• Exaltation: This is the ultimate goal for faithful Latter-day Saints. Also called “eternal life,” exaltation is not just about going to heaven to be with God; it is about progressing to become like God.² This highest form of salvation is only possible for those who participate in sacred temple ordinances, including being sealed in an eternal marriage, and remain faithful to the covenants they make there.¹⁴

While both groups have a component of works in their theology that sets them apart from the “faith alone” doctrine of mainstream Protestantism, the nature and purpose of those works are distinct. The Church of Christ’s emphasis on baptism is rooted in a specific command they believe is necessary for entering into a state of grace. The LDS emphasis on a lifetime of covenant-keeping and temple work is tied to their unique doctrine of eternal progression and the ultimate goal of achieving godhood. This means that when a member of the Church of Christ and a Latter-day Saint use the word “saved,” they are often referring to two profoundly different concepts and destinies.

What Can I Expect in a Worship Service?

Stepping into a worship service of either the Church of Christ or The Church of Jesus Christ of Latter-day Saints reveals a great deal about their core beliefs. The atmosphere, the music, and the central ordinances are all direct expressions of their foundational theologies of authority and scripture.

A typical worship service in a Church of Christ is marked by reverence, order, and a deliberate simplicity.¹⁷ Their goal is to worship God only in ways they see explicitly authorized in the New Testament, which they often call the “Five Acts of Worship”.¹²

• A Cappella Singing: Perhaps the most distinctive feature is that all singing is done a cappella, meaning without the accompaniment of any musical instruments. They believe that since the New Testament only mentions singing and making melody in the heart, the use of instruments is an unauthorized, man-made addition to worship.¹
• The Lord’s Supper: This is a central and solemn part of the service and is observed every Sunday.⁸ It is understood as a memorial to remember Christ’s sacrifice. Trays of unleavened bread and small cups of grape juice are passed to the congregation, who partake of these symbols of Christ’s body and blood.³⁰
• Preaching: A sermon, or lesson, based on the Bible is a primary element of the service.¹⁰
• Prayer: Prayers are offered to God, typically led by various men in the congregation.¹²
• Giving: A free-will offering is collected from members to support the work of the local church.²⁴

A Latter-day Saint Sacrament Meeting is also reverent but has a different structure and feel, often described as family-oriented and focused on personal commitment.³²

• Music: Worship includes hymns sung by the congregation, typically accompanied by a piano or organ. Often, a special musical number will be performed by a choir or other members.³³
• The Sacrament: This is the focal point of the meeting. After a hymn, worthy young men holding the Aaronic Priesthood bless bread and water using specific prayers from the Doctrine and Covenants.³³ Other young men then pass the sacrament to the congregation. For Latter-day this ordinance is primarily a weekly 

  renewal of the covenants they made at baptism to take Christ’s name upon them, always remember Him, and keep His commandments.³²

• Talks: Instead of a single sermon by a pastor, several “talks” are given by lay members of the congregation who have been assigned a gospel topic in advance. Youth are often invited to speak as well.³³
• Fast and Testimony Meeting: On the first Sunday of each month, the regular talks are replaced by a testimony meeting. After the sacrament, members of the congregation are invited to come to the pulpit spontaneously to share their personal testimony of the gospel.³²

The worship style of each group is a performance of their theology. The Church of Christ’s minimalist service reflects their conviction that they can only do what the Bible explicitly commands. The LDS sacrament meeting, with its lay speakers and structured program outlined in a handbook, reflects a church governed by a living, administrative priesthood authority.³² Even the central ordinance serves a different function: for the Church of Christ, it is a memorial looking back at the finished work of the cross; for Latter-day it is a covenant renewal looking forward to the ongoing work of the member.

Who Is in Charge? A Look at Church Leadership

The way a church is governed is a direct reflection of its beliefs about authority. In this area, the Church of Christ and The Church of Jesus Christ of Latter-day Saints could not be more different. One is structured for local independence, while the other is built as a global, unified hierarchy.

The Churches of Christ are defined by their fierce commitment to congregational autonomy.⁸ This means that each local church is completely independent and self-governing. There is no earthly headquarters, no central council, no president, and no denominational structure that exercises authority over the local congregations.¹⁰ They believe this is the pattern they see in the New Testament. A scripturally organized congregation is led by a plurality of male

elders, who are also referred to as bishops, overseers, or pastors.³⁵ These men must meet the specific qualifications listed in passages like 1 Timothy 3 and Titus 1. Their role is to spiritually shepherd, teach, and oversee only the local flock that appointed them.³⁶ They are assisted by

deacons, who are qualified male servants tasked with handling the physical and logistical needs of the freeing the elders to focus on spiritual matters.³⁵

In complete contrast, The Church of Jesus Christ of Latter-day Saints is a highly centralized, global hierarchy governed by what they believe is restored priesthood authority.³⁸ At the top of the entire church is the

First Presidency, which consists of the President of the Church (who is considered a living “prophet, seer, and revelator”) and his chosen counselors.¹³ They are assisted by the

Quorum of the Twelve Apostles, who are also considered prophets and special witnesses of Christ. Together, these two bodies oversee the affairs of the worldwide church.³⁹

This authority flows down through a structure built on priesthood. In LDS belief, the priesthood is the literal power and authority of God, delegated to worthy male members.⁴¹ This power is essential for performing ordinances like baptism and for leading the church. Local congregations, called

wards, are led by a bishop, who holds specific priesthood “keys” to preside over his ward.³⁸ Several wards are grouped into a

stake, which is overseen by a stake president. All these leaders operate within a clear line of authority that traces back to the prophet.⁴¹

The very concept of “priesthood” marks a critical distinction. In the Church of Christ, like most of Protestantism, leadership is an office to which a qualified man is appointed; authority resides in the scriptural role, not in the man himself. In Mormonism, leadership is based on holding the priesthood, a divine power that resides in the worthy man and gives him the authority to act in God’s name.⁴² This fundamental difference in governance is a direct result of their foundational claims: the Church of Christ seeks to replicate the perceived autonomy of New Testament churches, while the LDS Church is built to maintain the line of authority they believe was restored through Joseph Smith.

Why Do They Both Claim to Be the “Church of Christ”?

One of the most direct sources of confusion between the two groups is their historical connection to the name “Church of Christ.” Both movements, in their earliest days, adopted this name for the same reason: they were trying to restore what they believed was pure, New Testament Christianity and shed what they saw as unbiblical, “man-made” denominational labels like “Baptist,” “Methodist,” or “Presbyterian”.⁸

The leaders of the Stone-Campbell movement, which gave rise to the Churches of Christ, pleaded with believers to abandon “partyism” and unite under the simple name of “Christians”.⁴⁴ They looked to the New Testament and saw phrases like “the churches of Christ salute you” (Romans 16:16) as a divine precedent. For them, “church of Christ” was not a formal denominational title but a simple, biblical description of who owns the church: Christ Himself.¹⁷ They have held to this conviction, continuing to identify as Churches of Christ and rejecting outside labels like “Campbellites” as divisive.⁸

Similarly, when Joseph Smith formally organized his followers on April 6, 1830, the official name of the new organization was the “Church of Christ”.¹³ Like the Stone-Campbell reformers, he and his followers saw this as a return to the original, biblical name for the Lord’s church. For the first few years of its existence, this was the name they used.

The divergence occurred in 1838. According to LDS history, Joseph Smith received a revelation from God that declared the official name of the church moving forward: “For thus shall my church be called in the last days, even The Church of Jesus Christ of Latter-day Saints” (D&C 115:4).¹³ The term “Latter-day” was added to distinguish the modern, restored church from the “Former-day” church of the New Testament era. This name change was a pivotal moment. It signaled the LDS Church’s definitive move away from a simple biblical restorationism toward an identity defined by new, ongoing revelation from a living prophet. The act of changing the name

by revelation was a tangible demonstration of the very authority that set them apart from groups like the Churches of Christ, who remained bound to the biblical text as their only guide.

How Do They View Other Christian Churches?

A group’s view of other churches reveals its core claims about itself. Both the Church of Christ and The Church of Jesus Christ of Latter-day Saints hold exclusivist positions, meaning they each believe they are the one true church Christ established. But the basis for their exclusive claims is quite different.

The Churches of Christ view all other denominations as having departed from the pattern of the New Testament church.⁸ They see the history of Christianity as one of addition and corruption, where human traditions, creeds, and organizational structures were added to the simple faith taught by the apostles.⁵ Their plea is for Christian unity, but this unity is to be achieved when all other believers abandon their denominational practices and traditions and adopt the “restored” pattern of worship and organization found in the Churches of Christ.⁴⁴ They do not see themselves as just another denomination among many; they believe they are a restoration of the one church you read about in the Bible.¹¹ Their argument with other Christian churches is primarily over

practice and biblical interpretation.

The Church of Jesus Christ of Latter-day Saints teaches a more radical and complete break with historic Christianity. Their foundational narrative is that of a “Great Apostasy”.⁵ They believe that after the death of the original apostles, the true doctrines of the gospel were corrupted and, most importantly, the priesthood authority—the power to act in God’s name—was completely lost from the earth.⁶ According to this view, all of Christianity—Catholic, Orthodox, and Protestant—is the product of this apostasy and lacks divine authority. They believe that The Church of Jesus Christ of Latter-day Saints is the

only true and living church on the face of the earth because it is the only one where priesthood authority has been restored directly from heaven to a modern prophet, Joseph Smith.⁶ Their argument with other churches is not about interpretation; it is about

legitimacy and authority.

This creates two different kinds of exclusion. The Church of Christ’s claim is based on having the correct pattern. They believe other Christians are sincere but mistaken in their practices. The LDS claim is based on having the only valid priesthood. They believe other churches, no matter how sincere, lack the divine authority necessary to perform valid ordinances like baptism or to lead people to the highest degree of salvation.

What Is the Catholic Church’s Official Stance on Their Baptisms?

For many Christians seeking to understand different groups, the position of the Roman Catholic Church can serve as a helpful theological benchmark. As the largest and oldest Christian body, its official rulings on the sacraments provide insight into how a group is viewed in relation to historic, creedal Christianity. The Catholic Church teaches that for a baptism to be valid, it must have the correct “matter” (water), “form” (the Trinitarian formula: “I baptize you in the name of the Father, and of the Son, and of the Holy Spirit”), and “intent” (the minister intends to do what the Church does).⁴⁶

Based on these criteria, the Catholic Church’s view on baptisms from these two groups is starkly different.

The baptism performed in the Churches of Christ is generally considered valid by the Catholic Church.⁴⁸ This is because the Churches of Christ are Trinitarian in their doctrine of God. Even if they avoid the word “Trinity,” they believe in the Father, the Son, and the Holy Spirit as the one God of the Bible. They use water and the proper Trinitarian formula. Therefore, the Catholic Church recognizes that they are baptizing into the same Triune God as historic Christianity. A person converting from the Church of Christ to Catholicism would not be re-baptized, as their original baptism is seen as a true and effective sacrament that incorporated them into the Body of Christ.⁵⁰

In contrast, the baptism performed in The Church of Jesus Christ of Latter-day Saints was officially declared invalid by the Vatican’s Congregation for the Doctrine of the Faith in 2001.⁵¹ The reason for this ruling is not a disagreement over the use of water or the words of the formula, but a fundamental difference in the understanding of God.⁵² The Catholic Church concluded that because the LDS Church does not believe in the Trinity, the words “Father, Son, and Holy Spirit” do not mean the same thing. For Latter-day these words refer to three separate gods in a polytheistic or henotheistic system, not the single, tri-personal God of Christianity.⁵² Therefore, the Vatican ruled that Mormon baptism is not Christian baptism because it is an initiation into a different faith with a different God. A Mormon who wishes to become Catholic must be baptized, as they are considered not to have been baptized at all.⁵³

This official ruling powerfully illustrates the theological reality: the differences between the Church of Christ and mainstream Christianity are largely matters of practice and interpretation among fellow Trinitarians. The differences between Mormonism and mainstream Christianity are matters of fundamental doctrine, beginning with the very nature of God Himself.

What Is Their Ultimate Mission in the World?

The ultimate mission of a church defines its purpose and shapes its activities. While both the Church of Christ and The Church of Jesus Christ of Latter-day Saints are driven by a desire to share their message, the scope and nature of their missions are shaped by their unique theologies and end-times beliefs.

The mission of the Churches of Christ is primarily evangelical and restorative. Their prime directive, as they see it in the New Testament, is to preach the gospel of Jesus Christ to a lost world.¹⁷ This involves calling people to believe in Jesus, repent of their sins, and be baptized for the forgiveness of those sins. A key part of this mission is calling people out of what they consider to be man-made denominational systems and into the one, true church patterned after the New Testament.¹² Their focus is on the salvation of individuals and the planting of pure, autonomous congregations. Their view of the end times is generally amillennial, meaning they do not focus on a literal thousand-year reign of Christ on earth, but rather on the present work of the church in this age until Christ’s final return for judgment.⁸

The mission of The Church of Jesus Christ of Latter-day Saints is far more expansive, encompassing not only the living but also the dead, and is explicitly focused on preparing for a literal, earthly kingdom. Their mission is often summarized in three parts:

1. Proclaim the Gospel: This involves a massive, worldwide missionary effort to convert people to the restored church.¹³
2. Perfect the Saints: This means helping members live the gospel, keep covenants, and prepare for exaltation.¹³
3. Redeem the Dead: This is a unique aspect of their mission, involving vast genealogical research to identify ancestors and perform saving ordinances (like baptism) for them by proxy in their temples.¹³

Central to their mission is the belief in the “literal gathering of Israel” and the building of “Zion,” a New Jerusalem, on the American continent.² Their eschatology is distinctly millennialist; they believe they are preparing the world for the Second Coming of Jesus, after which He will reign personally on the earth for a thousand years from this American Zion.²

This difference in mission explains their organizational structures. The Church of Christ’s mission requires only a network of independent, local churches focused on evangelism. The LDS Church’s grand, theocratic mission to gather a global people, redeem all of humanity’s dead, and build a literal kingdom requires the complex, hierarchical, and data-driven organization that characterizes their church today. One is focused on restoring the church in the present; the other is focused on building a kingdom for the future.
