What disturbs the peace of unity is ambition, the vice that steals away from itself the soul which abandons itself to it, tearing it, as it were, in pieces, and dispersing it. The resplendent light of truth, who will not lose it in the mud, in the darkness of lust? Avarice and cupidity steal from us goodness, for it is the peculiar property of goodness to communicate to others the goods which it possesses. Thus, when Plato asked himself why God had created the world, he answered: "because he was good." These are the three vices: pride of life, concupiscence of the flesh, concupiscence of the eyes, which, as St. John says, are of the world and not of the Father who is unity, goodness, and truth indeed.
Let us therefore fly from the world, which is confirmed in evil; let us soar to the Father in whom are the peace that unifies, the true light, and the greatest happiness. But what will give us wings to soar? The love of the things that are above. What will take them from us? The lust for the things below, to follow which is to lose unity, truth, and goodness.
