Nontrinitarianism

===Modern Christian groups===
* [[Christadelphians]] hold the unitarian belief that although Jesus is the Son of God, this is only a relational title toward the Father who alone is truly God.

* The [[Members Church of God International]] believes in the divinity of Christ but rejects the doctrine of Trinity. 
* [[Oneness Pentecostalism]] is a subset of [[Pentecostalism]] that believes God is only one person, and that he manifests himself in different ways, faces, or "modes": "Father, Son, and Holy Spirit (or Holy Ghost) are different designations for the one God. God is the Father. God is the Holy Spirit. The Son is God manifest in flesh. The term Son always refers to the [[Incarnation]], and never to deity apart from humanity."<ref>{{cite web|url=http://ourworld.compuserve.com/homepages/pentecostal/One-Top.htm|archive-url=https://web.archive.org/web/20080216034825/http://ourworld.compuserve.com/homepages/pentecostal/One-Top.htm|title=The Oneness of God|archive-date=16 February 2008|access-date=5 March 2015}}</ref> Oneness Pentecostals believe that Jesus was "Son" only when he became flesh on earth, but was the Father prior to being made human. They refer to the Father as the "Spirit" and the Son as the "Flesh". Oneness Pentecostals reject the Trinity doctrine, viewing it as pagan and unscriptural, and hold to the [[Jesus' Name doctrine]] with respect to baptisms. Oneness Pentecostals are often referred to as [[Sabellianism|"Modalists"]] or [[Sabellianism|"Sabellians"]] or "Jesus Only".<ref name=fp123-4>{{cite book |last1=Patterson |first1=Eric |last2=Rybarczyk |first2=Edmund |title=The Future of Pentecostalism in the United States |publisher=Lexington Books |year=2007 |location=New York |pages=123–124 |isbn=978-0-7391-2102-3 }}</ref>
* Denominations within the [[Seventh-day Sabbatarianism|Sabbatarian]] tradition ([[Armstrongism]]) believe that Christ the Son and God the Father are co-eternal, but do not teach that the Holy Spirit is a being or person. Armstrong theology holds that God is a "Family" that expands eventually, that "God reproduces Himself", but that originally there was a co-eternal "Duality", God and the Word, rather than a "Trinity".
* [[Swedenborgianism]] holds that the Trinity exists in one person, the Lord God Jesus Christ. The Father, the being or soul of God, was born into the world and put on a body from [[Mary, mother of Jesus|Mary]]. Throughout his life, Jesus put away all human desires and tendencies until he was completely divine. After his resurrection, he influences the world through the Holy Spirit, which is his activity. In this view, Jesus Christ is the one God; the Father as to his soul, the Son as to his body, and the Holy Spirit as to his activity in the world. This view is very similar in many ways to Sabellianism, Modalism, Oneness, or Jesus Only beliefs.
* Numerous [[Unitarianism#Modern Christian Unitarian organizations|Unitarian Christian organizations]] exist around the world, the oldest of which is the [[Unitarian Church of Transylvania]]. An [[umbrella organization]] for these groups is the [[International Council of Unitarians and Universalists]], though only some members and affiliates of that body consider themselves exclusively or predominantly Christian. In the United States, "Unitarian" often refers to members and congregations within the [[Unitarian Universalist Association]] (UUA), a non-Christian group formed in 1961 from the merger of the [[American Unitarian Association]] with the [[Universalist Church of America]].<ref>{{Cite web|url=https://www.uuworld.org/articles/stevenson-2017-ware-lecture|title=Bryan Stevenson weaves story, policy in 2017 Ware Lecture|last=McCardle, Elaine and Kenny Wiley|date=2017-06-28|website=UU World|access-date=2019-09-17|quote=Stevenson referred to the UU faith's members repeatedly as "Universalists," which caught the attention of several social media users.
