Unitarian Universalists, often associated with the Unitarian church, are part of a growing religious movement worldwide. This liberal religion emphasizes inclusive and progressive values. So, what exactly is Unitarianism?

Unitarianism rejects the traditional doctrine of the Trinity, including the deity of Christ. The movement emerged from the Protestant Reformation, focusing on the oneness of God. Unitarians deny the Trinitarian concept of Father, Son, and Holy Spirit as distinct persons of God. This article explores Unitarianism’s history, belief system, and inherent contradictions with the heart and precepts of true Christianity.

The History of Unitarianism

The Protestant Reformation

The tumultuous Protestant Reformation of the 16th century birthed Unitarianism. This period challenged not only the Roman Catholic Church’s authority but also many traditional Christian doctrines.

Early reformers like Martin Luther and John Calvin initially focused on issues within the Catholic Church, such as justification by faith alone and the importance of biblical authority. As the Reformation progressed, some began exploring deeper theological questions about God’s nature. This led to the emergence of Unitarian thoughts.

Key Figures in Early Unitarianism

• Michael Servetus (1511-1553): This Spanish physician and theologian influenced early Unitarian thought. Servetus challenged orthodox Trinitarian doctrine, arguing for God’s singular and indivisible nature. He saw the Trinity as an erroneous concept detracting from divine unity. Servetus’ radical views led to his persecution and execution for heresy.

• Fausto Sozzini (1539-1604): This Italian theologian influenced the Polish Brethren, a group that embraced Unitarian ideas. Sozzini rejected the pre-existence of Christ and the doctrine of original sin. He laid the groundwork for a new liberal religious tradition.

These early Unitarian thinkers championed reason and critical examination of religious texts. They encouraged open-minded, spiritual inquiry, setting the stage for a faith that valued personal autonomy and diverse teachings. Their ideas resonated with those seeking a more rational approach to Christianity, free from perceived doctrinal contradictions.

As Unitarian ideas spread, they began to shape a distinct spiritual practice. This new approach emphasized direct experience of the divine and a responsible search for truth and meaning. It laid the foundation for the diverse, inclusive faith communities that characterize modern Unitarian Universalism.

Unitarianism in Europe

Unitarianism gained momentum in Europe, particularly in Transylvania, Hungary, and England, as it deviated from orthodox Christian doctrine. Key developments include:

• Transylvania’s Religious Freedom: In 1568, Transylvania’s King John Sigismund declared religious freedom, allowing Unitarians to practice openly. This tolerance enabled the spread of beliefs that contradicted traditional Christian teachings.

• English Nonconformism: Unitarianism emerged alongside other nonconformist movements in England, further challenging established church doctrines. During the 17th and 18th centuries, influenced by Enlightenment ideals, English Unitarians advocated for using reason in matters of faith. However, this approach led them to reject fundamental Christian beliefs, including the Trinity.

The prominent English Unitarians Joseph Priestly and Theophilus Lindsey significantly shaped the movement. Their writings and sermons promoted open-minded spiritual inquiry. They established some of the first Unitarian churches in England, promoting ideas that deviated from biblical Christianity.

These European Unitarians laid the groundwork for regular worship services that emphasized intellectual engagement. They encouraged congregants to question traditional doctrines and seek their own understanding of the divine. This approach attracted freethinkers and those dissatisfied with biblical teachers. It also resulted in a significant departure from historic Christian beliefs.

As Unitarianism took root in Europe, it developed a unique blend of Christian heritage and Enlightenment philosophy. European Unitarians laid the groundwork for regular worship services that emphasized intellectual engagement. They encouraged congregants to question traditional doctrines and seek their understanding of the divine.

Their legacy continues to influence modern Unitarian Universalism. Today’s Unitarian Universalist congregations still reflect this European heritage of religious freedom, rational inquiry, and social progressivism. Yet, they stand apart from orthodox Christianity in their beliefs about God, Christ, and salvation.

Unitarianism in North America

Unitarianism took root in North America during the early 19th century, diverging further from orthodox Christian beliefs:

• William Ellery Channing: Often called the “father of American Unitarianism,” Channing promoted a rational, liberal approach to Christianity. This approach, however, rejected core Christian doctrines, including the Trinity and Christ’s divinity.

• The American Unitarian Association: In 1825, the American Unitarian Association formed, uniting congregations that had departed from traditional Christian teachings. This organization provided a framework for Unitarian ideas to spread across the United States.

• New England Roots: Unitarian ideas gained particular traction in New England, especially among intellectuals and some church leaders. Many Congregational churches in this region gradually adopted Unitarian beliefs.

Throughout the 20th and 21st centuries, Unitarianism evolved away from its Christian roots. It embraced increasingly progressive values that often conflicted with orthodox Christian beliefs, attracting followers seeking a less dogmatic spiritual path.

Today, Unitarian Universalism, resulting from a merger between Unitarianism and Universalism, represents a religious movement distinct from Christianity. It welcomes people from various spiritual backgrounds, including those who reject traditional Christian doctrines.

While Unitarian Universalists may engage in social justice issues, their motivations and theological foundations differ from those of orthodox Christians. Their interpretation of Jesus’ teachings often conflicts with traditional Christian understanding.

Core Beliefs of Unitarianism

A Rejection of the Doctrine of the Trinity

Unitarianism fundamentally rejects the traditional Christian doctrine of the Trinity. Instead of believing in God as three distinct persons—Father, Son, and Holy Spirit—Unitarians uphold the concept of God’s oneness and unity. They argue that the Trinity was not divinely inspired but a later human construct.

Unitarians believe people can experience God’s essence directly, without intermediaries. This view simplifies their approach to spirituality, avoiding what they see as complexities in the Trinitarian concept.

An Emphasis on Reason and Rationality in Discerning Spiritual Truth

Unitarianism strongly emphasizes reason and rationality as essential tools for interpreting and understanding religious truth. The use of reason is central to Unitarian thought, as they believe that God has endowed humanity with the ability to discern moral and spiritual insights through rational thinking. This commitment to intellectual exploration encourages a critical examination of religious texts, doctrines, and traditions.

Many Unitarians also draw inspiration from humanist teachings, which emphasize human potential and ethical living without supernatural beliefs. This focus on reason and humanism often leads to a skeptical view of traditional religious claims and miracles.

A Value of Personal Autonomy

individual conscience holds high value in Unitarian thought. Rather than strict adherence to dogma, Unitarianism encourages people to explore their own beliefs and convictions. This emphasis on personal autonomy creates individuals who maintain unique spiritual journeys, often guided by personal experience rather than rigid doctrine. This search for truth and meaning extends to all aspects of life, including matters of sexual orientation and gender identity.

A Belief in the Fallibility of Scripture

While Unitarians respect and draw inspiration from sacred texts, such as the Bible, they do not view them as infallible. They believe these texts have historical context. They approach scriptural interpretation by acknowledging the cultural and linguistic factors that influence how these texts are written and transmitted. Unitarians balance scriptural authority with reason, conscience, and contemporary knowledge.

Unitarian beliefs regarding Scripture diverge significantly from orthodox Christian doctrine. Unitarians depart from the teachings of Jesus Christ, the prophets, and the New Testament authors by questioning the sovereignty and sufficiency of God’s Word. Three key instances in Scripture emphasize the importance and authority of God’s Word:

• Jesus affirmed Scripture’s authority, stating that “Scripture cannot be broken” (John 10:35) and that not even the smallest detail of the law would disappear (Matthew 5:18).

• The prophet Isaiah declared that God’s Word “will not return to me empty, but will accomplish what I desire” (Isaiah 55:11), highlighting its power and purpose.

• The Apostle Paul taught that “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness” (2 Timothy 3:16).

These passages, among others, form the foundation for the Christian understanding of Scripture’s divine inspiration and authority. While Unitarians value the Bible as a source of wisdom, their view of it as fallible and subject to human interpretation places them outside mainstream Christian doctrine on this essential point.

Unitarianism and Christianity

Historical connections and fundamental theological differences characterize Unitarianism’s relationship with traditional Christian doctrine. As mentioned earlier, Unitarianism emerged from the Protestant Reformation, which sought to challenge the teachings of the Roman Catholic Church. It has since evolved to become one of the liberal Christian traditions, thought it ulitimately developed into a distinct religious tradition. The doctrine of Unitarianism and its rejection of the Trinity, separates it from traditional Christian values.

The Nature of God – Unity vs. Trinity

The core belief of Unitarianism is the unity of God. Unlike traditional Christian theology, which affirms the Trinity (God as Father, Son, and Holy Spirit), Unitarians assert that God is one indivisible entity.

They often view God more abstractly, sometimes as a universal spirit or life force rather than a personal deity.

This rejection of the Trinity is the fundamental distinction between Unitarian and orthodox Christian beliefs. While traditional Christians interpret Jesus’s statement, “I and the Father are one,” as affirming His divinity and the Trinity, Unitarians often view this as a metaphorical expression of unity in purpose.

Biblical Christianity views the Holy Spirit as a divine person of the Trinity, as described in “When the Spirit of truth comes, he will guide you into all truth.” Unitarians often interpret the Holy Spirit as a metaphor for divine inspiration or human reason.

The Nature of God – Jesus Christ

Regarding Jesus Christ, Unitarians diverge sharply from mainstream Christian teaching. While orthodox Christianity affirms Jesus as fully divine and fully human, the second person of the Trinity, Unitarians generally view Jesus as a human being – albeit an exemplary moral teacher and prophet.

The verse “For in Christ all the fullness of the Deity lives in bodily form” is central to the Christian belief in Jesus’ full divinity. Unitarians may interpret this as hyperbole or as referring to Jesus’s exemplary embodiment of divine attributes. They do not accept His divine nature or His role in salvation as understood by traditional Christian doctrine.

Unitarian Changing Perspectives on God

It’s important to note that Unitarian perspectives on God and Jesus have evolved over time. Modern Unitarian Universalism, which emerged from the merger of Unitarianism and Universalism, often embraces a wide range of beliefs about the divine, including views from non-Christian religions and humanist philosophies.

From a biblical Christian standpoint, these Unitarian beliefs contradict clear biblical teachings about the nature of God and the person of Jesus Christ. The Bible affirms the Trinity and the full divinity of Jesus in numerous passages, which form the foundation of traditional Christian theology.

Common Values vs. Theological Differences

While Unitarians and biblical Christians may share some common values, such as a commitment to social justice, their fundamental understanding of God’s nature and Jesus’ identity remains starkly different. These theological distinctions highlight the importance of careful study and understanding of Scripture in forming one’s beliefs about God and shaping one’s faith tradition.

Apart from the rejection of the Trinity, several other theological differences distinguish Unitarianism from mainstream Christian denominations. One of the most prominent differences is the nature of Jesus Christ. In traditional Christianity, Jesus is regarded as the divine Son of God and the second person of the Trinity, fully divine and fully human. In contrast, Unitarians generally view Jesus as a highly revered and exemplary human being, a moral teacher, and a prophet. 

The Nature of Humanity

Unitarians diverge from orthodox Christianity on several key doctrinal points. They reject the concept of original sin and the need for atonement through Jesus’ death. Christians see “But God demonstrates his own love for us in this: While we were still sinners, Christ died for us” as affirming substitutionary atonement. Unitarians often interpret Christ’s death as an example of self-sacrifice rather than a necessary atonement for sin.

Rejection of Eternal Punishment

Unitarians also typically reject the concept of eternal punishment, favoring a more inclusive view of ultimate reconciliation. Instead, Unitarian Universalists emphasize human responsibility and moral agency, focusing on personal growth and redemption through individual actions and ethical living.

The Concept of Salvation

The concept of salvation also marks a significant theological difference. While mainstream Christian denominations emphasize faith in Jesus Christ as the pathway to salvation and eternal life, Unitarians affirm a more inclusive view. They believe people of various faith traditions, or even those without explicit religious beliefs, can attain salvation through living virtuous lives and seeking truth and goodness.

Christians understand Jesus’s claim, “I am the Way, the Truth, and the Life. No one comes to the Father except through me, ” declaring salvation’s exclusivity through Jesus Christ. Unitarians typically interpret this more broadly, seeing Jesus as exemplifying a way of life rather than being the sole path to God.

Faith in Jesus Christ

Despite these significant doctrinal differences, Unitarianism and traditional Christianity do share certain values and ethical principles. However, from an orthodox Christian perspective, these shared values do not negate the fundamental differences in theology. As Jesus explains in John 14:6, “I am the way and the truth and the life. No one comes to the Father except through me.” This verse underscores the Christian belief that good works alone cannot save a person – only faith in Jesus Christ can.

The Bible teaches that Christ died for us while we were still sinners, making a way for us to be counted righteous before God the Father. As John 1:17 states, “For the law was given through Moses; grace and truth came through Jesus Christ.” This imputed righteousness, Christ’s compelling love, and the indwelling of the Holy Spirit create in believers a desire to turn from sinful ways and follow Him. These core beliefs form the foundation of traditional Christian doctrine and highlight the key differences with Unitarian theology.

Unitarian Worship and Practices

UU congregations approach worship with diversity and adaptability, reflecting their liberal religious traditions. Their services often blend elements from world religions and humanist teachings, creating unique spiritual experiences. Some congregations also incorporate elements from earth-centered traditions, recognizing the spiritual significance of nature and ecological awareness.

Unitarian congregations encourage participatory worship, where members actively shape services. They may incorporate various elements like music, poetry, and creative arts. A common symbol in UU worship is the flaming chalice, which represents the light of reason, the warmth of the community, and the flame of hope.

Biblical View of True Worship

This approach contrasts sharply with orthodox Christian worship, which centers on biblical truth and the gospel of Jesus Christ. Jesus clearly defines true worship in John 4:23-24:

“Yet a time is coming and has now come when the true worshipers will worship the Father in the Spirit and in truth, for they are the kind of worshipers the Father seeks. God is spirit, and his worshipers must worship in the Spirit and in truth.”

This passage emphasizes that authentic worship aligns with God’s revealed truth and is guided by the Holy Spirit.

Intellectual Engagement vs. Faith-Centured Devotion

Unitarian services often focus on intellectual engagement and critical thinking. Sermons often encourage critical thinking, ethical exploration, and the application of reason to matters of faith and social issues. Unitarian churches often maintain a tradition of the free pulpit, where ministers are encouraged to speak their conscience on various issues. The goal is to inspire personal growth and spiritual development. Unitarians critically examine their convictions rather than being handed a fixed set of beliefs. While thoughtful reflection is valuable, orthodox Christianity prioritizes faith in Christ and obedience to God’s Word. As Paul writes in Romans 12:2, “Do not conform to the pattern of this world, but be transformed by the renewing of your mind.”

Social Justice and Community Involvement

Unitarian worship emphasizes a strong connection with community living. Social gatherings, educational programs, and community service projects contribute to building a close-knit and compassionate society. These activities often embody a celebration of life, reflecting the Unitarian emphasis on finding meaning and joy in the present world.

Unitarians often take an active stance on various social issues, such as civil rights and environmental sustainability.

Inclusivity is another hallmark of Unitarian worship. Unitarian congregations welcome people from all backgrounds, beliefs, and identities. Similarly, Christianity extends God’s love to all. However, it also calls for repentance and faith in Christ, as stated in Acts 17:30-31: “God commands all people everywhere to repent. For he has set a day when he will judge the world with justice by the man he has appointed.”

Inclusivity

Unitarianism and certain progressive Christian denominations advocate for inclusivity and welcome individuals from diverse backgrounds and beliefs into their communities. Both traditions share the values of embracing diversity and acknowledging every individual’s inherent worth and dignity. However, biblical Christianity adheres to Jesus’s teachings about salvation’s narrow path.

Jesus invites all people to Himself but clearly states in Matthew 7:14, “Small is the gate and narrow the road that leads to life, and only a few find it.” Jesus succinctly says that only those who acknowledge Him as Lord and Savior will be saved. He unequivocally claims divinity in John 8:58, saying, “Before Abraham was born, I am!” These statements form the cornerstone of traditional Christian doctrine.

Encouraging dialogue and understanding between Christians and Unitarians is essential for the Great Commission, which Jesus entrusted to His disciples – to go out and make disciples of all men, baptizing them in the name of the Father, the Son, and the Holy Spirit. He left those following Him in no doubt that the Trinity was truth and that there was only one Way to salvation.

Love and Compassion

Jesus’s core teachings, which emphasize love for one’s neighbor, compassion, and care for others, resonate with Unitarian values. 

Christians and Unitarians share common values like compassion and social justice. These shared ideals can serve as a starting point for constructive conversations. Through open dialogue, joint community service, and educational initiatives, both groups can gain insights into each other’s spiritual practices and beliefs.

Global Outreach and the Great Commission

As we consider Unitarianism’s global reach in the next section, it’s crucial to remember Jesus’ words in Matthew 28:19-20: “Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.” This Great Commission challenges Christians to share the gospel worldwide, offering the hope and salvation found only in Christ.

Unitarianism in the Modern World

Unitarianism has experienced significant growth and spread throughout the modern world, extending its reach beyond its historical roots in Europe and North America. The principles of inclusivity, reason, and social justice have resonated with individuals seeking a progressive and open-minded religious community.

Unitarianism Across the Globe

Unitarianism has spread globally, establishing roots in various countries. It thrives in nations with historical ties to the United Kingdom, Germany, Hungary, and Romania. The movement has also gained traction in North and South America, with growing congregations in Brazil, Mexico, and Jamaica. In Asia, Unitarian communities blend their principles with local cultural traditions, particularly in India, the Philippines, and Japan. The International Council of Unitarians and Universalists, along with the Unitarian Universalist Association of Congregations, helps coordinate and support the growth of Unitarian communities worldwide.

However, this global expansion raises important theological considerations. Jesus Christ calls believers out of worldly traditions and into a personal relationship with Him. As stated in 2 Corinthians 5:17, “Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!” True Christianity acknowledges Jesus as Lord, Savior, and Messiah – the only atoning sacrifice for humanity’s sins because He is the Son of God, the third person on the Triune God.

Jesus confirmed the Trinity, saying in John 14:9, “Anyone who has seen me has seen the Father.” This statement underscores the inseparable nature of the Godhead, a fundamental doctrine of orthodox Christianity.

Belief and Practice

In recent years, Unitarian organizations have actively promoted their principles and advocated for social justice. While these efforts align with Christian values of compassion and equality, they often lack the gospel’s transformative power.

Theological diversity remains a point of debate within Unitarianism. Some advocate for a more Christian-oriented approach, while others embrace a multi-religious perspective. This contrasts with biblical Christianity’s clear call to unwavering faith in Christ. As Peter proclaimed in Acts 4:12, “Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.”

As Unitarianism evolves, Christians are called to engage with love and truth. The apostle Paul’s words in Ephesians 4:15 guide this approach: “Speaking the truth in love, we will grow to become in every respect the mature body of him who is the head, that is, Christ.”

Foundational Truths About Jesus

While it is useful to understand Unitarianism’s unique perspectives, true Christianity is marked by a belief in the infallible nature of the Word of God and the deity of Jesus Christ, the Son of God. As we’ve explored throughout this article, these foundational truths distinguish biblical faith from other belief systems.

Jesus unequivocally stated in John 14:6, “I am the Way and the Truth and the Life. No one comes to the Father except through me.” This declaration underscores the exclusivity of Christ’s role in salvation, a core tenet of Christian doctrine.

While we’re called to engage with others in love and respect, we must also heed the Great Commission. In Matthew 28:19-20, Jesus instructs His followers to “go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” This command outlines our mission and affirms the Trinity’s divine nature.

Conclusion

The urgency of our times and the promise of Christ’s return should compel us to share the full, Bible-based gospel with a world in need. Only through faith in Jesus as Lord and Savior does a person gain entrance to eternal life. As Paul emphasizes in Romans 10:9, “If you declare with your mouth, ‘Jesus is Lord,’ and believe in your heart that God raised him from the dead, you will be saved.” This truth applies to all, including those in Unitarian or other faith traditions.

In our interactions with Unitarians and others, regardless of their religious affiliation, let us embody the love of Christ while standing firm in biblical truth. May we be guided by Peter’s instruction in 1 Peter 3:15 to “always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect.”

As we conclude, let’s remember that true spiritual life and eternal salvation come only through faith in Jesus Christ as Lord and Savior. We’re called to share this message of hope with all people, inviting them into a transformative relationship with the living God.
