“See how great a preparation you need, to be able to say boldly to God, O Father, for if you have your eyes fixed on worldly things, or court the praise of men, or are a slave to your passions, and utter this prayer, I seem to hear God saying, ‘Whereas you that are of a corrupt life call the Author of the incorruptible your Father, you pollute with your defiled lips an incorruptible name. For He who commanded you to call Him Father, gave you not leave to utter lies. But the highest of all good things is to glorify God’s name in our lives. Hence He adds, Hallowed be thy name. For who is there so debased, as when He sees the pure life of those who believe, does not glorify the name invoked in such a life. He then who says in his prayer, Be thy name, which I call upon, hallowed in me, prays this, ‘May I through Your concurring aid be made just, abstaining from all evil.'”  -Saint Gregory of Nyssa, Father of the Church, as quoted in the Catena Aurea of Saint Thomas Aquinas in the Commentary on Luke 11:1-4
