First Council of Constantinople

First Council of ConstantinopleAlthough the First Council of Nicaea had condemned the Arian belief and reasserted the dogma that the Father and the Son were of the same substance, some theologians believed that the Holy Spirit, the third Person of the Trinity, differed in substance from the other two Persons, being a kind of ‘creature’ of the second Person. This heresy was called Macedonianism.

In May 381 a second Ecumenical Councils was summoned by Theodosius I (378­95) to meet in Constantinople in the church of St. Irene to define the nature of the Holy Spirit. He had recognized Christianity as the official religion of his empire a year before. The emperor had done his homework carefully and already instructed the Churches that the object of the council would be the reconfirmation of the Nicene Creed. This time no representatives came from Rome.

The council reaffirmed the Nicene faith in the sense that it reasserted the keywords ‘of the same substance’, or homoousios and that the Holy Spirit was of the same substance with the Father and the Son. This council brought an end to Arianism, which had already been split into smaller dissensions, within the empire. It continued on among the Goths, who were converted among many other Arian missionaries by Ulfila (311-83), translator of the Gothic Bible, and among Vandals and Lombards.

The most important decision which concerned the Church hierarchy was that ­to the vexation of Alexandria- ‘the bishop of Constantinople should have rank after the bishop of Rome because it is New Rome.’ Thus Constantinople replaced Alexandria which until then had held the second place after Rome and also moved above Antioch and Jerusalem.

The church as established in the middle east has been established under the concept of unity IE catholic and or ecumenical. For the earliest Christian communities the concept of unity was one were the church communities agreed on a doctrinal understanding of Christianity. A doctrine based on the tradition of unity within the different ancient Christian communities. Unity established in what was taught to the communities by Christ and then his apostles. When various persons or groups within the many ancient Christian communities began to come to odds with innovations or interpretations of the tradition of Christianity the communities set out to clarify the validity of the variation in the comparison to traditional understanding. To establish why this change was to be accepted or rejected. As such was the case of the first council in Jerusalem. The later councils where prompted to clarify tradition and address what was proper and what was improper. Proper being what was established by Jesus Christ and then his apostles, then the Seventy and the clergy of the churches that take their linage directly back to the Apostolic era. Innovations being that which changed the understanding that Christian communities.
