Background He presided over the second
First Council of Constantinople called by
Emperor Theodosius. However, he was not originally in control. Rather, he arrived after the conference had already begun, led by
Gregory of Nazianzus and
Melitius of Antioch. But Melitius died soon thereafter and Gregory resigned his role as bishop, which resulted in Timothy presiding over part of the council. This council was also known as the Second Ecumenical Council, with the
Council of Nicaea being the first. In addition to the 150 Orthodox (that is, conforming to the decisions of the Council of Nicaea), there were also 36
followers of Macedonius.
Precedence of Episcopal Sees Constantinople, the city that hosted this council, had gained much in importance since the emperor
Constantine the Great transformed it into an imperial capital. This council determined that the see of
Alexandria ranked third in importance, after both
Rome and
Constantinople. Both Timothy and the Bishop of Rome rejected this claim, considering Alexandria to remain second only to Rome in the ranking of Christian cities.
Theological decisions According to Coptic
hagiography Timothy played a large part at the council. He condemned
Macedonius for his belief that the
Holy Spirit was created instead of existing from the beginning of time. Similarly, he questioned
Sabellius for his belief that the
Trinity was in fact a singularity, that each member was the same as each other member. He also argued with
Apollinaris who claimed that
Jesus did not have a human mind or soul because his divine nature replaced them. Each of these views was condemned as heretical and the originators, who refused to recant them, were excommunicated. However, this source should perhaps not be taken completely literally, since Macedonius seems likely to have died shortly after being deposed in 360 AD and Sabellius was excommunicated around 220 AD and therefore could not have been alive over a century and a half later when the council was held. Nevertheless, the author of the text puts Timothy in direct dialogue with those theologians he accuses of heresy, rather than their followers. ==Influence==
