Oneness Pentecostalism has a historical precedent in the
Modalistic Monarchianism of the second and third centuries. The early movement affirmed two central aspects of later Oneness belief: • There is one indivisible God with no distinction of persons or components within God's eternal essence. • Jesus was the manifestation, human personification, and/or incarnation of the same singular God. Oneness Pentecostals contend, based on
Colossians 2:9, that the concept of God's personhood is reserved for the immanent and incarnate presence of Jesus only.
Doctrine of God Oneness theology maintains that God is a singular spirit who is absolutely and indivisibly unitary, not three persons, individuals, or minds. They contend that the terms "
Father", "
Son", and "
Holy Ghost" (or "Holy Spirit") are titles reflecting the different personal manifestations of God in the universe. To Oneness believers, the Father, Son, and Holy Spirit are three manifestations of one personal God. Oneness theologians often quote a phrase used by early pioneers of the movement: "God was manifested as the Father in creation, the Son in redemption, and the Holy Ghost in emanation." However, Oneness theologian David Norris points out that this does not mean that Oneness Pentecostals believe that God can only be one of those manifestations at a time, which may be suggested by the quote. Oneness theologian
David K. Bernard also teaches that God is not limited to these three manifestations. According to Oneness theology, the Father and the Holy Spirit are the same personal God. It teaches that the term "Holy Spirit" is a descriptive title for God manifesting himself through the broader Christian Church. These two titles—as well as others—do not reflect divisible persons within the Godhead, but rather two different ways in which the one God reveals himself to his creatures. Thus, when the
Old Testament (
Hebrew Bible) speaks of "the Lord God and his Spirit" in
Isaiah 48:16, it does not indicate two distinct persons, according to Oneness theology. Instead, "the Lord" means God in all his glory and transcendence, while "his Spirit" refers to his Holy Spirit that moved upon and spoke to the Hebrew prophets. Bernard states that this passage does not imply two persons any more than the numerous scriptural references to a man and his spirit or soul (such as in
Luke 12:19) imply two "persons" existing within one body. Bernard asserts that it is unbiblical to describe God as a plurality of persons in any sense of the word, "regardless of what persons meant in ancient church history." Oneness Pentecostals maintain that early Christianity taught a form of strict
monotheism consistent with their view, contrasting their views not only with Trinitarianism but equally with the theology espoused by
Latter-day Saints (who believe that Jesus is a separate god from the Father and the Spirit), and by
Jehovah's Witnesses and
Unitarians (who deny the full deity of Jesus and view him as a created being distinct from and subordinate to the Father). The Oneness position as
nontrinitarian places them at odds with most mainstream Nicene
Christian denominations, and some
apologetics ministries and writers have categorized Oneness groups as
cults. However, David A. Reed, a Trinitarian scholar at
Wycliffe College and a leading academic authority on Oneness Pentecostalism, He contends in his book ''"In Jesus' Name": The History and Beliefs of Oneness Pentecostals'' that the movement should be considered theologically
heterodox, rather than
heretical or cultish.
Accusations of Modalism and Arianism Oneness believers are frequently identified with
Modalism. Additionally, some criticsusually individuals rather than denominational bodieshave also alleged that Oneness theology bears resemblance to
Arianism or
Semi-Arianism. While Bernard acknowledges similarities between Oneness theology,
Modalistic Monarchianism, and the teachings of
Sabellius, he rejects associations with
Patripassianism,
Arianism or
Subordinationism that have historically been linked to some modalistic views. Bernard argues that Oneness theology represents a distinct, biblical form of modalism that differs from some traditional formulations and interpretations historically deemed heretical. Thus, Oneness Pentecostals believe that the title "Son" only applied to
the Christ when he became flesh on earth. The Father in this theology embodies the divine attributes of the Godhead, and the Son embodies the human aspects. Oneness Pentecostals believe that Jesus and the Father are one essential person, though operating in different modes. In the incarnation, Oneness believers hold that God put the Word (which was his divine plan) into action by manifesting himself in the form of the man Jesus, and thus "the Word became flesh". As an extension, Oneness Pentecostalism argues that the incarnation was a singular event unlike anything God has done prior or will ever do again. Oneness Pentecostals believe that the Word of John 1:1 does not imply a second pre-existent, divine person but that the Word is simply the plan of God, which was put into action through the incarnation. Oneness Pentecostals see this not as two persons in one body but instead as two natures united in one person: Jesus. Oneness believers see the mystery referred to in
1 Timothy 3:16 as referencing this concept of two natures being united in the one person of Jesus. Although the Oneness belief in the union of the divine and human into one person in Jesus is similar to the
Chalcedonian formula, Chalcedonians disagree sharply with them over their opposition to Trinitarian dogma. Chalcedonians see Jesus as a single person uniting God the Son—the eternal second person of the Trinity—with human nature. Oneness believers, on the other hand, see Jesus as one single person uniting the one God himself with human nature as the Son of God.
Scripture Oneness Pentecostalism subscribes to the doctrine of
sola scriptura in common with mainstream Pentecostals and other Protestants. They view the Bible as the
inspired Word of God, and as absolutely
inerrant in its contents (though not necessarily in every translation). They specifically reject the conclusions of church councils such as the
First Council of Nicaea and the
Nicene Creed. They believe that mainstream Christians have been misled by long-held and unchallenged "traditions of men".
The name of Jesus The overwhelming emphasis on the person of Jesus shapes the content of a theology based on experience among both Oneness and Trinitarian Pentecostals. In principle, the doctrinal emphasis on Jesus attributes all divine qualities and functions to the Christ. What might, therefore, be called a 'Christological maximalism' in the Pentecostal doctrine of God among Oneness Pentecostals leads to a factual substitution of the three divine persons with the single person of Jesus. At the same time, Trinitarian Pentecostals typically elevate Jesus from the second person of the Trinity to the
central figure of Christian faith and worship. Critics of Oneness theology commonly refer to its adherents as "
Jesus Only", implying that they deny the existence of the Father and Holy Spirit. Oneness believers insist that while they do indeed believe in baptism only in the name of Jesus Christ, to describe them as "Jesus Only Pentecostals" implies a denial of the Father and Holy Spirit. This historical claim is not unique to Oneness Pentecostals. Some editions of the
Oxford Dictionary of the Christian Church,
Encyclopædia Britannica, and the
Internet Encyclopedia of Philosophy, among others, note that Trinitarianism formally developed over the early centuries as a response to theological controversies. The
Stanford Encyclopedia of Philosophy states that no Christian theologians were Trinitarian for the first three centuries, with a diverse range of views regarding the Father, Son, and Holy Spirit. Prominent biblical scholars such as
James D.G. Dunn,
Raymond E. Brown,
N.T. Wright, and
Larry Hurtado, affirm that while the
New Testament portrays Jesus and the Holy Spirit in ways that laid the groundwork for later formalized Trinitarian theology, it does not present the fully developed doctrine. They describe the Trinity as a theological synthesis formed in the post-apostolic era, drawing on the New Testament's presentation of Jesus and the Spirit within a monotheistic framework. Other scholars argue that Trinitarian doctrine represents a theological departure from the
unitarian monotheism of the
earliest Christians.
Bart Ehrman, an agnostic historian of
Early Christianity, and Jewish scholar
Géza Vermes contend that neither Jesus nor his earliest followers taught Trinitarian concepts and that the doctrine was a product of later reflection. Jewish scholars such as
Daniel Boyarin, and
Alan F. Segal have examined how
Second Temple Jewish concepts—such as divine agency and the "two powers" tradition—provided theological categories that early Christians adapted in ways that eventually contributed to Trinitarian thought. Both Jewish scholars document how concepts of divine agency informed early Christian understandings of Jesus, but neither identifies the Trinity as a biblically or historically continuous doctrine. Trinitarian theologians and apologists maintain that the doctrine represents a faithful synthesis of biblical revelation, developed more fully in response to early heresies and theological disputes. Figures such as
Alister McGrath and
Karl Rahner argue that the Trinity accurately expresses both the unity of God and the relational distinctions found in Scripture. Rahner, for instance, argued that "the
economic Trinity is the immanent Trinity," proposing that God's self-revelation in salvation history corresponds to his eternal triune identity. They maintain that the Trinity, though not formulated in creedal terms during the apostolic era, accurately expresses the unity and distinction presented in Scripture.
Views of the early church Scholars within the Oneness movement differ in their views on
church history. Some church historians, such as Dr. Curtis Ward, Marvin Arnold, and William Chalfant, hold to a
Successionist view, arguing that their movement has existed in every generation from the original day of
Pentecost to the present day. Ward has proposed a theory of an unbroken Pentecostal church lineage, claiming to have chronologically traced its perpetuity throughout the church's history. Others hold to a
Restorationist view, believing that while the
apostles and their church clearly taught Oneness doctrine and the Pentecostal experience, the early apostolic church went into
apostasy, which eventually developed into the institutional forms seen in
Roman Catholicism. For them, the contemporary Oneness Pentecostal movement began in America in the early 20th century during the latter days of the
Azusa Street Revival. Restorationists such as Bernard and Norris deny any direct link between the church of the
Apostolic age and the current Oneness movement, believing that modern Oneness Pentecostalism is a total restoration originating from a step-by-step separation within Protestantism culminating in the final restoration of the early apostolic church. Both Successionists and Restorationists among Oneness Pentecostals assert that the early apostolic church believed in the Oneness and
Jesus name baptism doctrines. David K. Bernard, a leading Oneness scholar, has written extensively on this subject in works such as
The Oneness of God and
A History of Christian Doctrine. Bernard traces Oneness adherents back to the first
converted Jews of the Apostolic Age and asserts that there is no evidence of these converts having any difficulty comprehending the
Christian Church's teachings and integrating them with their existing
Judaic beliefs. In the post-apostolic era, Bernard contends that the earliest believers, including
Hermas,
Clement of Rome,
Polycarp,
Polycrates,
Ignatius, and
Irenaeus either held to a Oneness-like view of God or followed an "economic Trinity" model that did not reflect eternal personal distinctions within the Godhead. Contemporary scholars widely reject Hislop's claims as unreliable; however, Bernard's core argument rests not on Hislop but on patristic sources and the biblical absence of explicitly tri-personal language. though Norris disagrees with them in his book
I AM: A Oneness Pentecostal Theology, arguing that writers like Ignatius should not be retroactively read through the lens of fourth-century Trinitarian orthodoxy. ==Soteriology==
