After the Council of Ephesus had condemned Nestorianism, there remained a conflict between Patriarchs John of Antioch and Cyril of Alexandria.

Cyril had taught that " There is only one physis, since it is the Incarnation, of God the Word.

Thus, Cyril followed his uncle in a position that had become powerful and influential, rivalling that of the prefect in a time of turmoil and frequently violent conflict between the cosmopolitan city's Pagan, Jewish, and Christian inhabitants.

When the Jews, with whom Cyril had clashed before, discovered the presence of Hierax, they rioted, complaining that Hierax's presence was aimed at provoking them.

This order had two aims: the first was to quell the riot, the other to mark Orestes ' authority over Cyril.

These monks ' violence had already been used, 15 years before, by Theophilus ( Cyril's uncle ) against the " Tall Brothers "; furthermore, it is said that Cyril had spent five years among them in ascetic training.

However, the Christian population of Alexandria knew that Ammonius had been killed for his assault and not for his faith, and Cyril was obliged to remain silent about the events.

Some Christians thought that Hypatia's influence had caused Orestes, the Praefectus augustalis of the Byzantine Diocese of Egypt | Diocese of Egypt, to reject all reconciliatory offerings by Cyril.

Several Christians thought that Hypatia's influence had caused Orestes to reject all reconciliatory offerings by Cyril.

Ephesus was friendly to Cyril, Emperor Theodosius convoked Council of Ephesus ( in 431 ) before Nestorius's supporters from Antioch and Syria had arrived and thus Nestorius refused to attend when summoned.

For example in the mid 350 ’ s the city of Jerusalem was hit with drastic food shortages at which point church historians Sozomen and Theodoret reported “ Cyril secretly sold sacramental ornaments of the church and a valuable holy robe, fashioned with gold thread that the emperor Constantine had once donated for the bishop to wear when he performed the rite of Baptism ”.

Besides his charitable works as Bishop Cyril had many responsibilities in City life.

Cyril got in trouble again when he appointed his nephew to bishop of Caesarea ; this was not the first time Cyril had appointed someone close to him to a high position in the Church.

Cyril did not return to Jerusalem until 366 after Valens had died.

Pope Cyril IV established very friendly relations with other denominations, to the extent that when the Greek Patriarch in Egypt had to absent himself for a long period of time outside the country, he left his Church under the guidance of the Coptic Patriarch.

Nestorius had come under fire from Western theologians, most notably Cyril of Alexandria.

Cyril had both theological and political reasons for attacking Nestorius ; on top of feeling that Nestorianism was an error against true belief, he also wanted to denigrate the head of a competing patriarchate.

Cyril of Jerusalem ( 346 AD ) in the sixth of his Catechetical Lectures prefaces his history of the Manichaeans by a brief account of earlier heresies: Simon Magus, he says, had given out that he was going to be translated to heaven, and was actually careening through the air in a chariot drawn by demons when Peter and Paul knelt down and prayed, and their prayers brought him to earth a mangled corpse.

After his return to Constantinople, Cyril assumed the role of professor of philosophy at the University while his brother had by this time become a significant player in Byzantine political and administrative affairs, and an abbot of his monastery.

It is a common misconception that Cyril and Methodius were the first to bring Christianity to Moravia, but the letter from Rastislav to Michael III states clearly that Rastislav's people " had already rejected paganism and adhere to the Christian law.

He then travelled to Jerusalem, where Cyril of Jerusalem faced opposition from local clergy due to the fact that he had been ordained by Acacius of Caesarea, an Arian heretic.

Cyril or Methodius had a hand in this ).

The formal definition of ' two natures ' in Christ was understood by the critics of the council at the time, and is understood by many historians and theologians today, to side with western and Antiochene Christology and to diverge from the teaching of Cyril of Alexandria, who always stressed that Christ is ' one '.

It could be that the reason for the Czech preference of Mieszko was the existence in Bohemia of a mission which followed the precepts of the Byzantine Greek brothers and later saints Cyril and Methodius, who developed and performed the liturgy in the Slavic rite, more readily understood by Mieszko and his subjects.

It was used by Saints Cyril and Methodius and their disciples to translate the Bible and other liturgical literature from Greek into Slavic.

He argues that the Greek Fathers, primarily Athanasius and Cyril of Alexandria were clear that we never share ontological union with God, but only this intimate fellowship.
