Where there is the love of God, “Christ is all and in all” and “there cannot be Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free man” “neither male nor female.” On the contrary, where self-love reigns, there one sees only oppositions, divisions, rivalries, envy, jealousy, dissensions, enmity, quarrels, aggression, all manifestations which are the fruits of this passion, as are unsociability, injustice, the exploitation of others and even murders and wars.
Self-love appears then to be deeply pathogenic on many levels, and is considered by the Fathers–as much in its nature as in its effects–as the mark of a man who has become mad and as itself being mad and profoundly irrational.
