Sunday of the Holy Fathers
On the Sunday that falls from the 13th to the 19th of the present month, we chant the Service to the Holy and God-bearing Fathers who came together in the Seven Ecumenical Councils, that is: the First Council, of the 318 Fathers who assembled in Nicaea in 325 to condemn Arius, who denied that the Son of God is consubstantial with the Father; the Fathers of the First Council also ordained that the whole Church should celebrate Pascha according to the same reckoning; the Second Council, of the 150 Fathers who assembled in Constantinople in 381 to condemn Macedonius, Patriarch of Constantinople, who denied the Divinity of the Holy Spirit; the Third Council, of the 200 Fathers who assembled in Ephesus in 431, to condemn Nestorius, Patriarch of Constantinople, who called Christ a mere man and not God incarnate; the Fourth Council, of the 630 who assembled in Chalcedon in 451, to condemn Eutyches, who taught that there was only one nature, the divine, in Christ after the Incarnation, and Dioscorus, Patriarch of Alexandria, who illegally received Eutyches back into communion and deposed Saint Flavian, Patriarch of Constantinople, who had excommunicated Eutyches; the Fifth Council in 553, of the 165 who assembled in Constantinople for the second time to condemn Origen and Theodore of Mopsuestia, the teacher of Nestorius; the Sixth Council in 680, of the 170 who assembled in Constantinople for the third time, to condemn the Monothelite heresy, which taught that there is in Christ but one will, the divine; and the Seventh Council in 787, of the 350 who assembled in Nicaea for the second time to condemn Iconoclasm.
