They believe the three individual deities are "one" in will or purpose, as Jesus was "one" with his disciples, and that the Father, Son, and Holy Spirit constitute a single godhead united in purpose. Latter-day Saints believe that Christ is the Firstborn of the Father, that he is subordinate to God the Father (Matthew 26:39), and that Christ created the universe. Latter-day Saints do not subscribe to the ideas that Christ was unlike the Father in substance and that the Father could not appear on earth, or that Christ was adopted by the Father, as presented in Arianism. Latter-day Saints assert that both God and the resurrected Christ have perfected glorified, physical bodies, but do not otherwise classify deity in terms of substance. While Latter-day Saints regard God the Father as the supreme being and literal father of the spirits of all humankind, they also teach that Christ and the Holy Spirit are equally divine and that they share in the Father's "comprehension of all things". * The

Points of dissent

Nontrinitarian Christians with Arian or Semi-Arian views contend that the weight of scriptural evidence supports
Subordinationism Subordinationalism is a Trinitarian doctrine, where the Son (and sometimes the Holy Spirit included) are subordinate to the Father. Not only in submission and role, but with actual ontological subordination to varying degrees. Subordinationism is ...
, the Son's total submission to the Father, and God's paternal supremacy over the Son in every aspect. They acknowledge the Son's high rank at God's right hand, but teach that the Father is still greater than the Son in all things. While acknowledging that the Father, Son, and Spirit are essential in creation and salvation, they argue that that in itself does not confirm that the three are each co-equal or co-eternal. They also affirm that God is only explicitly identified as "one" in the Bible, and that the doctrine of the Trinity, which word literally meaning ''a set of three'', ascribes a co-equal threeness to the being of the infinite God that is not explicitly scriptural.


Scriptural support

Critics of the Trinity doctrine argue that, for a teaching described as fundamental, it lacks direct scriptural support. Proponents of the doctrine assert that although the doctrine is not stated directly in the New Testament, it is instead an interpretation of elements contained therein that imply the doctrine that was later formulated in the 4th century. William Barclay, a

'' states: : "One does not find in the NT the trinitarian paradox of the coexistence of the Father, Son, and Spirit within a divine unity." Catholic historian Joseph F. Kelly, speaking of legitimate theological development, writes: : "The Bible may not use the word 'Trinity', but it refers to God the Father frequently; the ''Gospel of John'' emphasized the divinity of the Son; several New Testament books treat the Holy Spirit as divine. The ancient theologians did not violate biblical teaching but sought to develop its implications. ... rius'potent arguments forced other Christians to refine their thinking about the Trinity." : : "At two ecumenical councils, Nicea I in 325 and Constantinople I in 381, the church at large defined the Trinity in the way now so familiar to us from the Nicene Creed. This exemplifies development of doctrine at its best. The Bible may not use the word 'Trinity', but trinitarian theology does not go against the Bible. On the contrary, Catholics believe that trinitarianism has carefully developed a biblical teaching for later generations."


Questions about co-equal deity of Jesus

American Catholic priest and Trinitarian, R.E. Brown (1928–1988), wrote a journal article that sorted relevant biblical verses into three classes. He described the following block as "texts that seem to imply that the title 'God' was not used for Jesus" and are "negative evidence which is often somewhat neglected in Catholic treatments of the subject": * , , , , , , , , , , , , , , , and ; he lists these as "texts where, by reason of textual variants or syntax, the use of 'God' for Jesus is dubious": * , Acts 20:28, , , , , , and ; and only finds the following three as "texts where clearly Jesus is called God": * , John 1:1, and John 20:28.

Matthew 26:39

In Jesus prays with a distinction between God and himself, "O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt.".


John 1:1

In John 1:1 there is a distinction between God and the Logos. Non-trinitarians claim a mistranslation of the second part of John 1:1 which, when literally translated word-for-word reads "and the word
ogos Ogo may refer to: Places * Ogo, Senegal (disambiguation) ** Ogo, Diourbel ** Ogo, Louga ** Ogo (arrondissement), Matam, Matam * Ogo Mountains, Somaliland, Somalia * Ōgo, Gunma, Japan; a town in Seta, Gunma ** Ōgo Station, Maebashi, Gunma, Jap ...

of ''theos'' is anarthrous, lacking a definite article, they believe the verse refers to Jesus' pre-human existence as "a god" or a divine one as distinct from "the God". Nontrinitarians also contend that the author of John's gospel could have written ''kai ho theos ên ho logos'' ("and the Word was the God") if that were his intended meaning. Others argue that the Greek should be translated as "and the Logos was divine" (with ''theos'' as an adjective), wherein the Logos is interpreted as God's "plan" or "reasoning" for salvation. According to Modalists, the Logos 'becoming flesh' refers to the "plan" or "eternal mind" of God being manifested in the birth of the man Jesus rather than the

of a pre-existent Jesus.


John 10:30

— Nontrinitarians such as Arians believe that when Jesus said, "I and the Father are one," he did not mean that they were actually "one substance", or "one God", or co-equal and co-eternal, but rather that he and the Father have a "unity of purpose", and that the context indicates that Jesus was saying that they were "one" in ''pastoral work''. The point being that the Father and the Son were united in the divine work of saving the 'sheep'. Nontrinitarian Christians also cite , wherein Jesus prayed regarding his disciples: "That they may all be one, as you, Father, are in me, and I in you, that they may be in us," adding "that they may be one even as we are one". They argue that the same Greek word (''hen'') for "one" throughout John 17 indicates that Jesus did not expect for his followers to literally become a single Being, or "one in substance", with each other, or with God, and therefore that Jesus also did not expect his hearers to think that he and God the Father were one entity either.


John 20:28–29

John 20:28 –29 — "And Thomas answered and said to Him, "My Lord and my God!" Jesus said to him, "Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed"". Since Thomas called Jesus ''God'', Jesus's statement appears to endorse Thomas's assertion. Nontrinitarians sometimes respond that it is plausible that Thomas is addressing the Lord Jesus and then the Father. Another possible answer is that Jesus himself said, "Is it not written in your law, I said, Ye are gods?" () referring to Psalm 82:6–8. The word "gods" in verse6 and "God" in verse8 is the same Hebrew word "'elohim", which means, "gods in the ordinary sense; but specifically used (in the plural thus, especially with the article) of the supreme God; occasionally applied by way of deference to magistrates; and sometimes as a superlative", and can also refer to powers and potentates, in general, or as "God, god, gods, rulers, judges or angels", and as "divine ones, goddess, godlike one". Therefore, the point being that Jesus was a power or mighty one to the Apostles, as the resurrected Messiah, and as the reflection of God the Father.


2 Corinthians 13:14

2 Corinthians 13:14 — "The Grace of the Lord Jesus Christ and the love of God and the sharing in the Holy Spirit be with all of you." It is argued by Trinitarians that the appearance of "Father, Son, and Spirit" together in Paul's prayer for Grace on all believers, and are considered essential for salvation, that the verse is consistent with a triune godhead. Nontrinitarians such as Arians reply that they do not disagree that all three are necessary for salvation and grace, but argue that the passage does not explicitly say that all three are co-equal or co-eternal.


Philippians 2:5–6

Philippians 2:5 –6 — "Have this mind among yourselves, which is yours in Christ Jesus, r "which was also in Christ Jesus",who, though he was in the form of God, did not count equality with God a thing to be grasped" (ESV). The word translated in the

has: "Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God." Nontrinitarians make the argument that the passage is simply saying that Christ did not consider equality with God something graspable, and that better English translations make it clearer. Another point is that the original Greek had no definite article for "form of God", which would mean "a form of divinity", and also that the term "morphe" for "form" in Koine Greek would simply mean a general external quality or station, but not necessarily the absolute thing itself, and therefore they argue that the passage does not explicitly teach either co-equality, co-eternity, or consubstantiality.


Hebrews 9:14

— "How much more will the Blood of Christ, who through an eternal Spirit, offered himself without blemish to God, cleanse our consciences from dead works, that we may render sacred service to the living God?" Most nontrinitarians agree that the Holy Spirit had no beginning, but believe it is not an actual person. Nontrinitarians contend that it is obvious that God the Father in the passage is the One who is ultimately reached, and therefore is greater than the other two entities, and that a "co-equal trinity" is not explicitly taught in the passage, but only inferred.


Terminology

"The term 'Trinity' is not in the Bible", and some nontrinitarians use this as an argument to state that the doctrine of the Trinity relies on non-biblical terminology, and that the number three is never clearly associated with God necessarily, other than within the

which is of spurious or disputed authenticity. They argue that the only number clearly unambiguously ascribed to God in the Bible is one, and that the Trinity, literally meaning three-in-one, ascribes a co-equal threeness to God that is not explicitly biblical. Nontrinitarians cite other examples of terms or phrases not found in the Bible; multiple "persons" in relation to God, the terms "

." Trinitarians see the absence of the actual word "Trinity" and other Trinity-related terms in the Bible as no more significant than the absence in the Bible of the words "monotheism", "omnipotence", "oneness", "Pentecostal", "apostolic", "incarnation" and even "Bible" itself. They maintain that, 'while the word ''Trinity'' is not in the Bible, the substance or drift of the doctrine is definitely biblical, if not explicitly than at least implicitly.'


Holy Spirit

Nontrinitarian views about the Holy Spirit differ from mainstream Christian doctrine and generally fall into several distinct categories. Most scriptures traditionally used in support of the Trinity refer to the

The Spirit is inherent in the Father and the Son, and emanates from Them throughout the entire universe."

, as with other modalist groups, teach that the Holy Spirit is a ''mode'' of God, rather than a distinct or separate person in the godhead, and that the Holy Spirit is another name for God the Father. According to Oneness theology, the Holy Spirit is the Father operating in a certain capacity or manifestation. The United Pentecostal Church teaches that there is no personal distinction between God the Father, the Son, and the Holy Spirit.See also David Bernard, ''A Handbook of Basic Doctrines'', Word Aflame Press, 1988. The two titles "Father" and "Holy Spirit" (as well as others) are said to not reflect separate "persons" within the Godhead, but rather two different ways in which the one God reveals himself to his creatures. The Oneness view of Bible verses that mention God and his Spirit (e.g. Isaiah 48:16) is that they do not imply two "persons" any more than various scriptural references to a man and his spirit or soul (such as in Luke 12:19) imply two "persons" existing within one body.


Latter-day Saint movement

In the Church of Jesus Christ of Latter-day Saints, the Holy Ghost (usually synonymous with Holy Spirit) is considered to be the third distinct member of the Godhead (Father, Son and Holy Ghost), and to have a body of "spirit", which makes him unlike the Father and the Son who are said to have bodies "as tangible as man's".D&C 130:22
According to LDS doctrine, the Holy Spirit is believed to be a person, with a body of spirit, able to pervade all worlds. Latter-day Saints believe that the Father, the Son, and the Holy Ghost are part of the Godhead, but that the Father is greater than the Son, and that the Son is greater than the Holy Spirit in position and authority, but not in nature (i.e., they equally share the "God" nature). They teach that the Father, Son, and Spirit are three ontologically separate, self-aware entities who share a common "God" nature distinct from our "human" nature, who are "One God" in the sense of being united (in the same sense that a husband and wife are said to be "one"), similar to Social trinitarianism. A number of Latter Day Saint sects, most notably the

In an 1897 article in the '' Jewish Quarterly Review'', Montefiore describes Unitarianism as a bridge between Judaism and mainstream Christianity, calling it both a "phase of Judaism" and a "phase of Christianity".

Purported pagan origins of the Trinity

Some nontrinitarians also say that a link between the doctrine of the Trinity and the Egyptian Christian theologians of

suggests that Alexandrian theology, with its strong emphasis on the deity of Jesus, served to infuse Egypt's pagan religious heritage into Christianity. They accuse the Church of adopting these Egyptian tenets after adapting them to Christian thinking by means of Greek philosophy. They say the development of the idea of a co-equal triune godhead was based on pagan Greek and Platonic influence, including many basic concepts from Aristotelian philosophy incorporated into the biblical God. As an example, they mention that
Aristotle Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of ...

This was adopted by 3rd and 4thcentury professed Christians as roughly corresponding to "Father, Word, and Spirit (Soul)". Nontrinitarian Christians contend that such notions and adoptions make the Trinity doctrine extra-biblical. They say there is a widely acknowledged synthesis of Christianity with Platonic

This was adopted by Origen and later on by Athanasius, and applied to the generation of the Son from the Father, because they believed that this analogy could be used to support the notion that the Father, as immutable, always had been a Father, and that the generation of the Son is therefore eternal and timeless. The synthesis of Christianity with Platonic philosophy was further incorporated in the trinitarian formulas that appeared by the end of the 3rd century. "The Greek philosophical theology" was "developed during the Trinitarian controversies over the relationships among the persons of the Godhead". The allegation of borrowing was raised by some disputants when the Nicene doctrine was being formalized and adopted by the bishops. For example, in the 4th century,

on Christianity. In particular:
Again in the doctrine of the Trinity, the ecclesiastical conception of Father, Word, and Spirit finds its germ in the different Stoic names of the Divine Unity. Thus Seneca, writing of the supreme Power which shapes the universe, states, 'This Power we sometimes call the All-ruling God, sometimes the incorporeal Wisdom, sometimes the holy Spirit, sometimes Destiny.' The Church had only to reject the last of these terms to arrive at its own acceptable definition of the Divine Nature; while the further assertion 'these three are One', which the modern mind finds paradoxical, was no more than commonplace to those familiar with Stoic notions.
