New Oikoumene

Let’s say that angels ruled were associated with the great powers of the ancient oikoumene (the period between Nebuchadnezzar and Nero). This is (perhaps) what’s in view in Daniel 10:13, 20.

Jesus establishes the new imperium , and in Revelation 2-3 sends out letters to the “angels” of the churches. I believe that the angels are pastors, so why call them angels? Perhaps Revelation 2-3 is giving us a portrait of the new empire, the oikoumene of Jesus, also ruled by angels.
