And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and who had not worshiped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
All Commentaries on Revelation 20:4 Go To Revelation 20
Andreas of Caesarea
AD 637
And I saw the seats. Already teaching thrones have been given to the holy apostles through whom the nations have been enlightened. They will be given, according to the divine promise also in the future for judging those who rejected the gospel preaching. And the souls of them.... they will judge the demons, until the consummation the present age, (the saints) being venerated by pious kings and faithful rulers, and manifesting God-given power against every bodily ailment and demonic activity.
Those liberated from them by Christ, according to the manner mentioned above, will co-reign until his second coming, afterwards enjoying these divine promises to an even greater degree.
