→The Council of Nicea: Arius had already been deposed and excommunicated prior to the First Council; it confirmed the previous local council's ruling
==The Council of Nicea==
In opposition to Arius, Alexander of Alexandria presented his case to [[Alexander of Constantinople]] and [[Eusebius of Nicomedia]], where the emperor was in residence. Although the emperor sent a legate to resolve the controversy and publically called upon Arius and Alexander to settle their differences, the dispute was of such a nature as to preclude any compromise. Accordingly, the arguments between Arius and his opponents continued, becoming such a powerful divisive force within the Roman empire that Constantine could no longer abide them. To settle the dilemma once and for all, he called a [[synod|council]] with delegates drawn from all the empire. The purpose of this, the [[First Ecumenical Council|First Council of Nicea]], was to determine as far as possible what had been taught by Jesus Christ and His [[Apostles]]. The Council met in Nicea, near Constantinople, in 325. Here, the confession of faith presented by Arius was cut to pieces. Guided by the emperor, the Council developed a creed, the [[Nicene-Constantinopolitan Creed|Nicene Creed]], for use in catechetical instruction and at baptisms. Arius himself was condemned as a heretic
, [[deposition |deposed]] from the priesthood , and exiled, together with his recalcitrant adherents. One of the champions of Orthodoxy to emerge from this council was [[Athanasius the Great]], an Alexandrian deacon who would eventually succeed Bishop Alexander and become one of the Church's greatest warriors against Arianism.
Although the council seemed to have settled the Arian issue once and for all, concern remained over the use of the word ''homoousios'' that was used in formulating the case against Arius. Early, ill-defined definitions of ''homoousios'' were part of the arguments used in deposing [[Paul of Samosata]] in 269; at the time, these were considered to have Sabellian tendencies. In his polemics against Arius, Alexander of Alexandria refined the definition of ''homoousios'' to mollify these earlier objections.
