, with Arius depicted beneath the feet of emperor
Constantine the Great and the
bishops Arianism would not be contained within the Alexandrian
diocese. By the time Bishop Alexander finally acted against his presbyter, Arius's doctrine had spread far beyond his own see; it had become a topic of discussion—and disturbance—for the entire Church. The Church was now a powerful force in the Roman world, with Constantine I having legalized it in 313 through the
Edict of Milan. "Constantine desired that the church should contribute to the social and moral strength of the empire, religious dissension was a menace to the public welfare." Consequently, the emperor had taken a personal interest in several ecumenical issues, including the
Donatist controversy in 316. He also wanted to bring an end to the Arian dispute. To this end, the emperor sent bishop
Hosius of Corduba to investigate and, if possible, resolve the controversy. Hosius was armed with an open letter from the Emperor:
"Wherefore let each one of you, showing consideration for the other, listen to the impartial exhortation of your fellow-servant." As the debate continued to rage despite Hosius' efforts, Constantine in AD 325 took an unprecedented step: he called an
ecumenical council at Nicaea composed of church
prelates from all parts of the empire to resolve this issue, possibly at Hosius' recommendation. It is traditionally said that 318 bishops came to Nicaea to attend the council, though others suggest figures from 250-300. The vast majority of those bishops were from the East. Italy, Spain, Gaul, North Africa, Persia, and Scythia each sent one bishop.
Pope Sylvester I, himself too aged to attend, sent two priests as his delegates. Arius himself attended the council as well as the young deacon Athanasius, who attended as an assistant to Alexander of Alexandria The council was presided over by the emperor himself, who participated in and even led some of its discussions. Those who upheld the notion that Christ was co-eternal and con-substantial with the Father were led by Alexander. Those who instead insisted that the Son of God came after God the Father in time and substance, were led by Arius the presbyter. For about two months, the two sides argued and debated, with each appealing to Scripture to justify their respective positions. Arius maintained that the Son of God was a Creature, made from nothing; and that he was God's First Production, before all ages. And he argued that everything else was created through the Son. Thus, said Arius, only the Son was directly created and begotten of God; furthermore, there was a time that He had no existence. He was capable of His own free will, said Arius, and thus "were He in the truest sense a son, He must have come after the Father, therefore the time obviously was when He was not, and hence He was a finite being." According to some accounts in the
hagiography of
Saint Nicholas, debate at the council became so heated that at one point, he slapped Arius in the face. The majority of the bishops at the council ultimately agreed upon a creed, known thereafter as the
Nicene Creed formulated at the first council of Nicaea. It included the word
homoousios, meaning "consubstantial", or "same in essence", which was incompatible with Arius' beliefs. On June 19, 325, council and emperor issued a circular to the churches in and around Alexandria: Arius and two of his unyielding partisans (Theonas and Secundus)
Ariminum, Seleucia, and Constantinople (358–360) In 358, the emperor
Constantius II requested two councils, one of the western bishops at Ariminum (now
Rimini in
Northern Italy) and one of the eastern bishops at
Nicomedia. In 359, the western council met at Ariminum.
Ursacius of Singidunum and
Valens of Mursa, following the new creed drafted at Sirmium (359), proposed that, "
according to the scriptures," the Son was "
like the Father." This is known as the
Homoian view which held that the Bible does not reveal whether the Son is of the same substance as the Father and we, therefore, should not speculate about such things. This view is in opposition to the "
of the same substance" (Homoousios) view of the Nicene Creed. The council, including some supporters of the older creed, accepted this proposal. An
earthquake struck Nicomedia, and in 359 the eastern council met at
Seleucia Isauria instead. The council was bitterly divided and procedurally irregular, and the two parties met separately and reached opposing decisions. Following the
Homoian view,
Acacius of Caesarea declared that the Son was "
like the Father". But
Basil of Ancyra and his party, following a (Homoiousian) Creed of Antioch from 341, declared that the Son was of "
similar substance" to the Father. The majority at Seleucia accepted the "
similar substance" view and deposed the opposing party. Constantius did not accept this outcome and requested a third council, at Constantinople (359), of both the eastern and western bishops, to resolve the split at Seleucia. Acacius and Basil of Ancyra, respectively, again proposed the "
like the Father" and "
similar substance" views, as were explained at Seleucia. However,
Maris of Chalcedon,
Eudoxius of Antioch, and the deacons
Aëtius of Antioch and
Eunomius of Cyzicus proposed a third view which was similar to Arius' teachings, namely that the Son was of "
a dissimilar substance" from the Father. The Heteroousians ("
dissimilar substance") won the victory over the other two views in an initial debate. However, Constantius was not willing to accept this outcome either. He intervened and banished Aëtius; At the same time, Acacius also deposed and banished the
Anomoean deacon Aëtius. According to
Philostorgius, pagans killed
George of Laodicea, bishop of
Alexandria, allowing Athanasius to reclaim the 'see', or ecclesiastical jurisdiction. ==Sides==
