I realized that what he is saying is that God created the ‘beloved’ because, without us, for eons God was an incomplete (imperfect) “egocentric non-personality.”
Perhaps Blessed Fulton Sheen can help you with this?
From Fulton Sheen...
If we would seek out the mystery of why love has a triune character and implies lover, beloved, and love, we must mount to God Himself. Love is Triune in God because in Him there are three Persons and in the one Divine Nature! Love has this triple character because it is a reflection of the Love of God, in Whom there are three Persons: Father, Son, and Holy Spirit. The Trinity is the answer to the questions of Plato. If there is only one God, what does He think about? He thinks an eternal thought: His Eternal Word, or Son. If there is only one God, whom does He love? He loves His Son, and that mutual love is the Holy Spirit. The great philosopher was fumbling about for the mystery of the Trinity, for his noble mind seemed in some small way to suspect that an infinite being must have relations of thought and love, and that God cannot be conceived without thought and love. But it was not until the Word became Incarnate that man knew the secret of those relations and the inner life of God, for it was Jesus Christ, the Son of God, Who revealed to us the inmost life of God.
It is that mystery of the Trinity which gives the answer to those who have pictured God as an egotist God sitting in solitary splendor before the world began, for the Trinity is a revelation that before creation God enjoyed the infinite communion with Truth and the embrace of infinite Love, and hence had no need ever to go outside of Himself in search for happiness. The greatest wonder of all is that, being perfect and enjoying perfect happiness, He ever should have made a world. And if He did make a world, He could only have had one motive for making it. It could not add to His perfection; it could not add to His Truth; it could not increase His Happiness. He made a world only because He loved, and love tends to diffuse itself to others. -Fulton J Sheen

Direct opposite of what Archbishop Hilairon says. The part about the Holy Trinity explaining Plato's questions is extremely telling, as it was very important for the early Church's acceptance among pagan Greeks to harmonize the pagan Greek Platonic ideas with the new religion, which was essentially alien (Jewish) to the Greeks, and to present Jesus as a Hellenized (demiugric Logos) concept rather than as a Jewish mashiyah. Nevertheless, this was not easy, which is why it too three hundred years to "hammer out." Even the First Ecumenical Council did not have it altogether (just base don the number of Credal versions that were floating around), as the Greed ends with a simple statement "And we believe in the Holy Ghost" without elaborating, or equating him with the Father and the Son.
