What defines Biblical Unitarianism?

Definition and Scope

Biblical Unitarianism is a theological position that asserts God is one person (the Father), and that Jesus is the Messiah but not eternally God in the same sense as the Father. Adherents typically regard the Holy Spirit not as a distinct person but rather as God’s spirit or power at work. While maintaining fidelity to Scripture, Biblical Unitarians interpret key biblical passages (e.g., John 1:1; John 10:30) in ways that emphasize the singular personhood of God over a triune interpretation.

This viewpoint, though varied in its modern expressions, broadly rejects what historical church councils (such as Nicaea in AD 325 and Chalcedon in AD 451) defined as the co-equal, co-eternal nature of the Father, Son, and Holy Spirit. Proponents of Biblical Unitarianism often appeal to a literal reading of certain New Testament texts to challenge traditional Trinitarian dogma, contending that the title “God” is applied preeminently and solely to the Father.


Core Theological Tenets

1. Absolute Oneness of God

Biblical Unitarians hold that the one God described in Scripture is the Father alone (cf. Deuteronomy 6:4). They often affirm 1 Corinthians 8:6: “yet for us there is but one God, the Father, from whom all things came and for whom we exist,” interpreting it to mean that the Father alone is fully God.

2. Christ as the Human Messiah

The position states that Jesus was uniquely begotten by God (Luke 1:35), but they maintain He did not share an eternal divine status with God the Father. Instead, He was a fully empowered and sanctified man—though miraculously conceived—who became the exalted Lord by virtue of His resurrection and ascension (Acts 2:36).

3. Holy Spirit as God’s Active Force

Instead of viewing the Holy Spirit as a co-equal person, Biblical Unitarians typically see the Spirit as God’s power or presence actively working in believers (cf. Acts 1:8). Because of passages like Luke 1:35 referring to the Holy Spirit overshadowing Mary, they see these as examples of God’s dynamic presence rather than a distinct personal being.

4. Rejection of Early Church Councils

Biblical Unitarians generally reject post-apostolic creeds (Nicene, Athanasian) that articulate the Trinity. They argue these formulations are later theological developments rather than teachings they find explicitly in Scripture.


Historical Overview

1. Early Roots

Various forms of unitarian thought existed among some groups in the first few centuries AD, though not widely prevalent. Writings from early Christian figures, such as Tertullian and Ignatius, indicate that the majority church held a view marking Jesus as divine and distinct from the Father, later codified in the Nicene Creed. Yet smaller sects occasionally questioned these claims.

2. Socinian Influence (16th–17th Centuries)

The term “Biblical Unitarian” often traces its theological lineage to the Socinian movement, which arose in the 16th century (named after Lelio and Fausto Sozzini). Socinians championed a strict monotheism, rejecting the notion of the Trinity and Christ’s preexistence. Their works, like the Racovian Catechism (1605), influenced later unitarian movements.

3. Modern Developments

In more recent centuries, Unitarian churches in Europe and North America sought a theological grounding in “scripture alone” to justify the belief in the singular personality of God. Some adopted a more rationalistic approach, distancing themselves from historical miracles, while others continued promoting biblical authority yet rejecting the Trinity.


Scriptural Interpretation and Key Passages

1. John 1:1

A central point of debate is the meaning of “the Word was God.” Biblical Unitarians often propose that “the Word” (Greek: Logos) refers to God’s plan or wisdom rather than a distinct person co-eternal with the Father. Yet many translations (including the Berean Standard Bible) read John 1:1 in a way consistent with Jesus’ divine nature: “In the beginning was the Word, and the Word was with God, and the Word was God.”

2. Colossians 1:15–17

This passage describing Christ as “the image of the invisible God” and the One “by whom all things were created” is typically explained by Biblical Unitarians in terms of Christ’s role in God’s redemptive and new-creation plan. They interpret “all things” as relating to the spiritual or church sphere, rather than the entire cosmos.

3. John 8:58

When Jesus states, “before Abraham was born, I am!”, Biblical Unitarians might emphasize alternative translations, suggesting it indicates Christ’s foreordination in God’s plan rather than literal preexistence. They contend this phrasing alludes to God’s predetermined purpose.

4. Matthew 28:19

The Trinitarian formula—“baptizing them in the name of the Father, and of the Son, and of the Holy Spirit”—is interpreted usually by Biblical Unitarians as a reference to God’s presence in different roles rather than separate persons with one essence.


Comparisons with Mainstream or Trinitarian Views

1. Nature of God

Mainstream Christian teaching, upheld in historical creeds and confessions, views God as one essence in three co-eternal, co-equal persons: Father, Son, and Holy Spirit. Biblical Unitarians hold that the one God is only the Father, with the Son and Holy Spirit subordinate or expressions of the Father’s power.

2. Christology

Orthodoxy sees Christ as fully divine and fully human, “the radiance of God’s glory” (Hebrews 1:3). Biblical Unitarianism interprets the New Testament focus on Christ’s humanity as total, insisting Christ’s divinity is representational or functional, not ontological.

3. Role of Holy Spirit

Traditional Christian doctrine affirms the personhood of the Holy Spirit. Biblical Unitarianism typically rejects a personal Holy Spirit, viewing references to the Spirit as figurative or descriptive of God’s action rather than a personal divine being.


Common Objections and Rebuttals

1. Consistency of the Biblical Narrative

Critics of Biblical Unitarianism argue that the entire sweep of Scripture—from creation (Genesis 1:2, John 1:1–3) to final redemption (Revelation 22:13) — testifies to the Son’s divine status and the Holy Spirit’s personhood. They point to places like Philippians 2:6–7 to claim Jesus “existed in the form of God.”

Biblical Unitarians respond that many of these passages have been read through a later doctrinal lens, suggesting the text can legitimately be interpreted to maintain a strict monotheism without personifying Christ’s deity.

2. Testimony of Early Manuscripts and Creeds

Manuscript evidence (such as P66, P75 for John’s Gospel) consistently preserves high Christology passages, contending Jesus was recognized as God early in the church. Conversely, Biblical Unitarians may counter that this does not prove the original teachings but might reflect historical developments in church theology.

3. Use of the Divine Name

Biblical Unitarians emphasize scriptural references like John 17:3, where Jesus addresses the Father as “the only true God,” as primary proof that worship belongs only to the Father. Traditional Christians clarify that identifying the Father as “the only true God” does not preclude the Son’s deity, as the New Testament also refers to Jesus with the title “God” (John 20:28; Titus 2:13).


Influence on Christian Community

1. Worship Practices

Biblical Unitarian groups tend to focus their worship exclusively on the Father, though Jesus is honored as Lord and Messiah. Hymns and prayers often omit direct adoration of Jesus as God when framed in strict unitarian terms.

2. Evangelism and Outreach

Some associate unitarian theology with a rationalist presentation of the gospel, using Scripture to argue for the straightforward oneness of God as more accessible to non-believers who struggle with Trinitarian formulations. Others question whether such an approach omits the historical Christian confession of the Son’s deity.

3. Modern Organizations

Numerous modern congregations, particularly smaller fellowships, identify with Biblical Unitarianism. Their writings often emphasize a return to a “purely biblical” faith, repudiating perceived church traditions they believe have overshadowed the original apostolic message.


Archaeological and Historical Considerations

While direct archaeological “proof” of either Triune or strictly unitarian formulations is elusive, archaeological findings like the early Christian inscriptions and church structures (e.g., the house churches in Dura-Europos from the 3rd century AD) reflect worship that included Christ in reverential or divine roles. Such artifacts align with the broader practice of prayer directed to or through Jesus, which some interpret as early acceptance of His divine status.

In contrast, fractional groups or isolated texts from church history might articulate a unitarian framework. Yet these have proven less prevalent than the mainstream witness exemplified by early Christian creedal affirmations. Even so, Biblical Unitarian proponents assert that marginalization of unitarian voices came not from lack of biblical basis but from ecclesiastical power centers endorsing Trinitarian statements.


Contemporary Dialogues and Debates

Biblical Unitarian scholars and Trinitarian theologians often engage in public debates, focusing on Greek syntax, church history, and the interpretive tradition. Some well-known dialogues hinge on the translation of John 1:1c as “the Word was with God, and the Word was God” versus a non-traditional rendering such as “the Word was fully expressive of God,” though these variations are rarely adopted in mainstream translations.

Public discussions also address Christological passages in the Pauline epistles, building on manuscript evidence that upholds or questions references to Jesus as “God over all” (Romans 9:5). Trinitarian apologists generally maintain the earliest extant manuscript evidence leans heavily toward a high Christology indicating more than a mere adoptive or figurative divine status for Jesus.


Conclusion

Biblical Unitarianism defines God as a single person—namely, the Father—and views Jesus as Messiah and Lord but not co-equal with the Father in a Trinitarian sense. Adherents underscore a clear and simple monotheism and interpret many New Testament references to Christ as either exalted imagery or functional equivalence rather than a statement of eternal deity.

This perspective has existed as a minority voice in Christian history—raised by a variety of groups from the Socinians onward—and continues to be a distinct interpretive framework in certain modern fellowships. It diverges significantly from Trinitarian theology affirmed by most Christian denominations, who read Scripture as revealing the eternal nature of Father, Son, and Holy Spirit in one divine essence.

Regardless of view, the unifying principle for those honoring the Bible is that Christ’s identity and mission remain central to God’s redemptive plan. As the Berean Standard Bible states in John 20:31: “But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name.”
