Giussani: On Friendship

...love creates reciprocity, generates reciprocity. This, in the Mystery, is nature. The nature of Being revealed itself in Jesus of Nazareth as love in friendship, that is as love acknowledged. Thus the mirror of the Father is the Son, the infinite Word, and in the infinite mysterious perfection of this acknowledgement - in which vibrates for us the infinite mysterious beauty of the Origin of Being, of the Father (Splendor Patris) - proceeds the mysterious creative power of the Holy Spirit. Now, the "I", the human "I", made in the image and likeness of God, reflects originally the Mystery of the one and triune Being, proper to the dynamism of freedom, whose law will therefore be love, and the dynamism in which this love is lived can be nothing else but friendship. 

You or about Friendship, pp. 17-18  Luigi Giussani

Astounding. To think that friendship in its perfect from is the Trinity, and that our human friendships are a participation in the triune love!
