Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 13:21-27

“Observe that Christ sends the Angels as well as the Father; where then are they who say that He is not equal to the Father? For the Angels go forth to gather together the faithful, who are chosen, that they may be carried into the air to meet Jesus Christ. Wherefore it goes on: And gather together his elect from the four winds.”
