666 Part Four Our awareness of our status as slaves would make us sink into the ground and our earthly condition would dissolve into dust, if the authority of our Father himself and the Spirit of his Son had not impelled us to this cry . . . ‘Abba, Father!’ . . . When would a mortal dare call God ‘Father,’ if man’s innermost being were not animated by power from on high?” 28 2778 This power of the Spirit who introduces us to the Lord’s Prayer is expressed in the liturgies of East and of West by the beautiful, characteristically Christian expression: parrhesia, straightforward simplicity, filial trust, joyous assurance, humble boldness, the certainty of being loved. 29 II. “F ather !” 2779 Before we make our own this first exclamation of the Lord’s Prayer, we must humbly cleanse our hearts of certain false images drawn “from this world.” Humility makes us recognize that “no one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him,” that is, “to little children.” 30 The purification of our hearts has to do with paternal or maternal images, stemming from our personal and cultural history, and influencing our relationship with God. 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. The expression God the Father had never been revealed to anyone. When Moses himself asked God who he was, he heard another name. The Father’s name has been revealed to us in the Son, for the name “Son” implies the new name “Father.” 31 2780 We can invoke God as “Father” because he is revealed to us by his Son become man and because his Spirit makes him known to us. The personal relation of the Son to the Father is something that man cannot conceive of nor the angelic powers even dimly see: and yet, the Spirit of the Son grants a participation in that very relation to us who believe that Jesus is the Christ and that we are born of God. 32 28 St. Peter Chrysologus, Sermo 71, 3: PL 52, 401CD; cf.
