Basil of Caesarea (probably) on Isaiah 9:5ff

"We have heard before how many names of the Lord we have already been taught by the prophet. 'Behold, a virgin shall conceive in her womb and shall beat a Son, and they shall call his name Emmanuel.' Here His name is called 'Messenger of great counsel'. He is the one Who made known the great counsel kept secret for the ages (Col. 1:26) and not manifested to other generations (Eph. 3:5). He is the one Who announced and manifested among the Gentiles His inscrutable wealth (Eph. 5:8), in order that the Gentiles should be fellow-heirs and the same body (Eph. 3:6) of Him whose sovereignty is upon His shoulder, that is Whose kingdom and power are on the cross; as having been lifted up on the cross He drew all to Himself (John 12:32). [...] There is no end of His peace, for the reason that it is a supramundane gift. For had it been from the world, it would have lasted only as long as the world exists. But now, he who has accepted His peace and preserved it shall live with the good things of His peace for ever. The peace of Solomon was limited to the recorded years, whereas the peace from the Lord is co-extensive with the whole of eternity, being unlimited and boundless. For all shall be subjected to Him and all shall recognise His mastery, and when God shall be all in all (1 Cor. 15:28), and those making an uproar by their apostasies are silences, all in peaceful harmony shall praise God with hymns." (Basil, En. in pr. Is. 9.227) (quoted from St. Basil the Great, Commentary on the Prophet Isaiah, translated by Nikolai A. Lipatov, p. 275-276)
