According to Augustine, it is common that earthly cities are founded by murderers. Fratricides to be exact (City of God, Bk. XV.5). In Scripture, we learn that the first city Cain who slew his brother Abel was the founder of the first earthly city. He was jealous of Abel’s favor before the Lord in offering a right sacrifice and so the sin crouching at his feet overwhelmed Cain as he overwhelmed his brother.
It’s no wonder, then, that he was followed in this “by a kind of reflection” in the founder of the archetypical “capital” of the earthly city of Rome. As the founding myth would have it, there were two brothers, Romulus and Remus. Disagreeing about which hill to build their future city on, they quarreled and Romulus slaughtered his brother, founded the city, and named it after himself. After that, Romulus built his armies, legions, and spread from there.
The two foundings, while similar, also reveal different conflicts at work. In the case of the second pair, Augustine thinks it is obvious what the root of the issue is: both Romulus and Remus were citizens of the City of Man whose aim is self-glory.
Both sought the glory of establishing the Roman state, but a joint foundation would not bring to each the glory that a single founder would enjoy. Anyone whose aim is to enjoy glory in the exercise of power would obviously enjoy less power if his sovereignty was diminished by a living partner. Therefore, in order that the sole power should be wielded by one person, the partner was eliminated; and what would have been kept smaller and better by innocence grew through crime into something bigger and worse.
As the lust for glory provokes Romulus to kill Remus, it would spill into further violence and bloodshed. The lust for dominance and glory is insatiable, and once it has found a crack in the wall, the dam inevitably bursts forth.
But what of Cain and Abel? There was a difference there, right? Cain was the founder of the first city and a representative of the City of Man, but Abel was a citizen of the “Eternal City” of God whose glory is the love of God. There was not “the same ambition for earthly gains”, and Cain was clearly not jealous of Abel’s power–he was a poor shepherd and their was no city to be founded yet. Instead, Augustine says that “Cain’s was the diabolical envy of that the wicked feel for the good simply because they are good, while they themselves are evil.”
Thus the quarrel that arose between Remus and Romulus demonstrated the division of the earthly city against itself; while the conflict between Cain and Abel displayed the hostility between the two cities themselves, the City of God and the city of men. Thus the wicked fight among themselves; and likewise the wicked fight against the good and the good against the wicked.
The city of man built on love of human glory and power is inherently destructive. It not only opposes the good, but eventually tears itself apart. Because human glory is a limited resource, those who desire it cannot share it. And, what’s more, they even hate those who do not seek it, because it seems to diminish their own pursuit of it. Try to opt out of the competition and it makes the prize at the end seem all the less desirable.
But what of the love of the city of God? What of the desire to possess goodness?
A man’s possession of goodness is in no way diminished by the arrival, or the continuance, of a sharer in it; indeed, goodness is a possession enjoyed more widely by the united affection of partners in that possession in proportion to the harmony that exists among them. In fact, anyone who refuses to enjoy this possession in partnership will not enjoy it at all; and he will find that he possesses it in ampler measure in proportion to his ability to love his partner in it.
Love of good and the God who is the Good is an inherently social love. Those who have it naturally seek out fellow citizens who with whom to delight and rejoice together. And this is the joy of the Heavenly Jerusalem that descends from above. There the citizens of the City of God will have their eternal good and delight together in their unchanging possession of, or rather, possession by, the Infinite, Unlimited Subject of their affection.
