At length in 381 the work of local Synods and episcopal conferences was completed and clinched by the Ruling of a Second Ecumenical Council.  It is true that the Council which Theodosius summoned to meet at Constantinople could scarcely have regarded itself as possessing Ecumenical authority; whilst in the West it certainly was not regarded in this light before the Sixth Century.  Nevertheless the honours of Ecumenicity were ultimately awarded to it by the whole Church, because it completes the series of Great Councils by which the Doctrine of the Deity of the Holy Spirit was affirmed; and in fact it expressed the final judgment of the Catholic Church upon the Macedonian controversy.  Its first Canon anathematises the Semiarians or Pneumatomachi by name as well as the Eunomians or Anomœan Arians (cf. Dict. Biog. Art. Gregory of Nazianzus, by Dr. H. B. Swete).
