John Chrysostom — as excerpted in the Catena Aurea on Matthew 6:13

“Having made us anxious by the mention of our enemy, in this that He has said Deliver us from evil, He again restores confidence by that which is added in some copies, For thine is the kingdom, and the power, and the glory, since if His be the kingdom, none need fear, since even he who fights against us, must be His subject. But since His power and glory are infinite, He can not only deliver from evil, but also make glorious.”
