Luke 11:1-10 - "Lord, teach us to pray, as John taught his disciples." And he said to them, "When you pray, say: “Father, hallowed be thy name. Thy kingdom come. Give us each day our daily bread; and forgive us our sins, for we ourselves forgive every one who is indebted to us; and lead us not into temptation." And he said to them, "Which of you who has a friend will go to him at midnight and say to him, `Friend, lend me three loaves; for a friend of mine has arrived on a journey, and I have nothing to set before him'; and he will answer from within, `Do not bother me; the door is now shut, and my children are with me in bed; I cannot get up and give you anything'? I tell you, though he will not get up and give him anything because he is his friend, yet because of his importunity he will rise and give him whatever he needs. And I tell you, Ask, and it will be given you; seek, and you will find; knock, and it will be opened to you. For every one who asks receives, and he who seeks finds, and to him who knocks it will be opened." (RSV - Gospel for the Fifth Tuesday of Luke)
Do you call God "Father"? – The Savior gives his own glory to us. He raises slaves to the dignity of freedom. He crowns the human condition with such honor as surpasses the power of nature. He brings to pass what was spoken of old by the voice of the psalmist: “I said, you are god, and all of you sons of the Most High.” He rescues us from the measure of slavery, giving us by his grace what we did not possess by nature, and permits us to call God “Father,” as being admitted to the rank of sons. We received this, together with all our other privileges, from him. One of these privileges is the dignity of freedom, a gift peculiarly befitting those who have been called to be sons.
He commands us, therefore, to take boldness and say in our payers, “Our Father” … that we, knowing well that we are sons of God, may behave in a manner worthy of him who has honored us. He will then receive the supplications that we offer in Christ. (St. Cyril of Alexandria)
