Holy Fathers of the Second Ecumenical Council
381
The Second Ecumenical Council was convened in Constantinople in the year 381, in the reign of the emperor Theodosius the Great. The Council met from May to July in the Church of Hagia Irene with one hundred and fifty Orthodox bishops in attendance, among whom were Saints Gregory the Theologian, who presided over a portion of its sessions, Gregory of Nyssa, Meletius of Antioch, Cyril of Jerusalem, and Amphilochius of Iconium. The Council consolidated the victory of Orthodoxy attained at the First Ecumenical Council in 325 by condemning the heresies of Macedonius, who denied the divinity of the Holy Spirit, of Apollinarius, who denied the full humanity of Christ, and of the followers of Eunomius and Sabellius. The Fathers expanded the Symbol of Faith of Nicaea by adding the articles concerning the Holy Spirit, producing the Niceno-Constantinopolitan Creed which the Orthodox Church confesses to this day. They also issued seven canons regulating the order of the Church, including the canon establishing the See of Constantinople as second in honour after Rome. The Holy Fathers of this Council are commemorated each year on 22 May.
