In honor of fathers everywhere I’d like to offer something beautiful and profound to you. So I’m going to post something from Scott Hahn’s book, Understanding the Our Father.  It’s more beautiful and profound than anything I can write and I really want to share it with you. Happy Father’s Day! May your day be richly blessed, and the rest of your days also! :)
The “Our” of Power
This is why Tradition tells us we must go beyond our earthly experiences and memories of fatherhood when we pray, “Our Father.” For though He is a provider, begetter, and protector, God is more unlike than like any human father, patriarch, or paternal figure. The Catechism puts it this way: “God our Father transcends the categories of the created world. To impose our own ideas in this area ‘upon him’ would be to fabricate idols to adore or pull down. To pray to the Father is to enter into his mystery as he is and as the Son has revealed him to us” (no. 2779).
How has Jesus, God the Son, revealed the Father to us? As “[o]ur Father who art in heaven” (Mt. 6:9). By adding that prepositional phrase “in heaven,” Jesus emphasizes the difference in God’s fatherhood. The Father to Whom we pray is not an earthly father. He is “above” us; He is the One we profess in the creed as “Father Almighty”—that is, all powerful. Though we are weak, limited, and prone to mistakes, nothing is impossible for God (cf. Lk. 1:37).
God’s power, then, sets His fatherhood apart from any fatherhood we have known or imagined. His “fatherhood and power shed light on one another” (Catechism, no. 270). Unlike earthly fathers, He always has the best intentions for His children, and He always has the ability to carry them out. Jesus wanted us to know this, so that we could always approach our heavenly Father with childlike trust and confidence: “[W]hatever you ask in prayer, you will receive, if you have faith” (Mt. 21:22).
The Catechism teaches that “God reveals his fatherly omnipotence by the way he takes care of our needs” (no. 270). We know God as Father because, over a lifetime of prayer, we experience His care for us. We come to see for ourselves that He is mighty, and that He will deny us nothing that is good for us. 
From Heir to Paternity
Earthly fatherhood sometimes reflects these characteristics, as do those offices that assume fatherly roles in society: the priesthood, for example, and the government. Yet earthly fathers can perfect their fatherhood only by purifying themselves of earthly motives—such as greed, envy, pride, and the desire to control. They can become true fathers only by conforming themselves to the image of their heavenly Father, and that Image is His firstborn Son, Jesus Christ.
In governing, in parenting, or in priesthood, we come to exercise a more perfect fatherly role as we “grow up” in the Family of God: “[W]e are children of God, and if children, then heirs, heirs of God and fellow heirs with Christ” (Rom. 8:16–17). This process is a divine corrective to the world’s distorted notions of patriarchy and hierarchy.
An ancient Christian writer, Dionysius the Areopagite, described hierarchy as something that originates in heaven, where divine light passes through the angels and the saints as if all were transparent.2 God’s gifts, then, are passed from one person to the next, undiluted. Those who are closest to God—and so higher in the hierarchy—serve those who are lower. At each stage, they give as God gives, keeping nothing to themselves.
Notice, here, how spiritual goods differ from material goods. If I have sole ownership of something—say, a sport coat or a tie—someone else can’t own it and use it at the same time. The higher goods, however, are spiritual; and spiritual goods—such as faith, hope, love, liturgy, the merits of the saints—can be shared and owned completely by all. That’s how the hierarchy works with the angels and saints in heaven.
For this sharing to take place “on earth as it is in heaven” requires the perfection of earthly fatherhood, which can take place only if we earnestly pray, “Our Father who art in heaven.” God is the primordial Father, “of whom all paternity in heaven and earth is named” (Eph. 3:15, Douay Rheims Version). He is the eternal model by which all human fathers must be measured.
