This ecumenical council was the first effort to attain consensus in the church through an assembly representing all Christendom. Hosius of Corduba may have presided over its deliberations.
Nicene Creed
The Nicene Creed (ˈnaɪsiːn; Sýmvolon tis Nikéas) is the defining statement of belief of Nicene or mainstream Christianity and in those Christian denominations that adhere to it. The original Nicene Creed was first adopted at the First Council of Nicaea in 325. In 381, it was amended at the First Council of Constantinople. The amended form is also referred to as the Nicene Creed, or the Niceno-Constantinopolitan Creed for disambiguation.
First Council of Constantinople
The First Council of Constantinople (Concilium Constantinopolitanum; Σύνοδος τῆς Κωνσταντινουπόλεως) was a council of Christian bishops convened in Constantinople (now Istanbul, Turkey) in AD 381 by the Roman Emperor Theodosius I. This second ecumenical council, an effort to attain consensus in the church through an assembly representing all of Christendom, except for the Western Church, confirmed the Nicene Creed, expanding the doctrine thereof to produce the Niceno-Constantinopolitan Creed, and dealt with sundry other matters.
Arius
Arius (əˈraɪəs,_ˈɛəri-; Ἄρειος, Áreios; 250 or 256 – 336) was a Cyrenaic presbyter, ascetic, and priest associated with the doctrine of Arianism. His teachings about the nature of the Godhead in Christianity, which emphasized God the Father's uniqueness and Christ's subordination under the Father, and his opposition to what would become the dominant Christology (Homoousian Christology) made him a primary topic of the First Council of Nicaea convened by Emperor Constantine the Great in 325.
Unitarianism
Unitarianism () is a Nontrinitarian branch of Christianity. Unitarian Christians affirm the unitary nature of God as the singular and unique creator of the universe, believe that Jesus Christ was inspired by God in his moral teachings and that he is the savior of humankind, but he is not comparable or equal to God himself. Unitarianism was established in order to restore "primitive Christianity before [what Unitarians saw as] later corruptions setting in"; Likewise, Unitarian Christians generally reject the doctrine of original sin.
Nontrinitarianism
Nontrinitarianism is a form of Christianity that rejects the mainstream Christian theology of the Trinity—the belief that God is three distinct hypostases or persons who are coeternal, coequal, and indivisibly united in one being, or essence (from the Ancient Greek ousia). Certain religious groups that emerged during the Protestant Reformation have historically been known as antitrinitarian.
Orthodoxy
Orthodoxy (from Greek: ὀρθοδοξία) is adherence to correct or accepted creeds, especially in religion. Orthodoxy within Christianity refers to acceptance of the doctrines defined by various creeds and ecumenical councils in Antiquity, but different Churches accept different creeds and councils. Such differences of opinion have developed for numerous reasons, including language and cultural barriers. Eastern Orthodoxy and Oriental Orthodoxy are sometimes referred to simply as "Orthodoxy".
Athanasius of Alexandria
Athanasius I of Alexandria (296–298 – 2 May 373), also called Athanasius the Great, Athanasius the Confessor, or, among Coptic Christians, Athanasius the Apostolic, was a church father and the 20th pope of Alexandria (as Athanasius I). His intermittent episcopacy spanned 45 years (8 June 328 – 2 May 373), of which over 17 encompassed five exiles, when he was replaced on the order of four different Roman emperors. Athanasius was a Christian theologian, a Church Father, the chief defender of Trinitarianism against Arianism, and a noted Egyptian Christian leader of the fourth century.

Arianism
Arianism (Ἀρειανισμός, Areianismós) is a Christological doctrine first attributed to Arius (AD 256–336), a Christian presbyter from Alexandria, Egypt. Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before "time" by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time as time applies only to the creations of God.
