Origen — as excerpted in the Catena Aurea on Luke 11:1-4

“Or, because the name of God is given by idolaters, and those who are in error, to idols and creatures, it has not as yet been so made holy, as to be separated from those things from which it ought to be. He teaches us therefore to pray that the name of God may be appropriated to the only true God; to whom alone belongs what follows, Thy kingdom come, to the end that may be put down all the rule, authority, and power, and kingdom of the world, together with sin which reigns in our mortal bodies.”
