While I probably don't have time to wade through 40+ pages (although I will try to do so), I would offer my willingness to serve as a resource as well in matters of religion: I am currently pursuing a PhD in Religious Studies, with a focus on the project of comparative religion. This is meant in support of this discussion, btw, and not at all as "taking anything from" Plotinus and his efforts.
I am explicitly _not_ particularly well versed in Christian theology, but do have a lot of knowledge wrt other religious traditions, ranging from the East to Islam to indiginous religions of Australia, America, and Africa to various "marginal" practices that flourish on the borders of mainstream religion.
That's great! As I have said, I know little about religions other than Christianity, so that should complement things nicely. Please post as freely as you like.
Which texts hint at him not being pacifist?
Matthew 10:34 said:
"Do not think that I have come to bring peace to the earth; I have not come to bring peace, but a sword."
Luke 22:36-38 said:
He said to them, "But now, the one who has a purse must take it, and likewise a bag. And the one who has no sword must sell his cloak and buy one. For I tell you, this scripture must be fulfilled in me, 'And he was counted among the lawless'; and indeed what is written about me is being fulfilled." They said, "Lord, look, here are two swords." He replied, "It is enough."
also it seems hard to me to think that he wouldn't have been interested about it, though this hardness might come from us understanding the word differently. Do you think there's a reason why (christian) ethics do not apply to politics (from the christian view)?
Don't forget that the early Christians - and probably Jesus too - thought the world was going to end any day. In 1 Thessalonians 4:15 (the earliest book of the New Testament to be written), Paul assumes that he and his readers will be alive at the end of the world. In that sort of context, personal ethics remain important (since one is still faced with moral decisions every day), and Paul gives ethical exhortations in the same letter, 4:1-12. But it would be very hard to see much point to politics. The earthly order was going to be rolled up and dissipated before long; why get involved in politics?
Even when the Christians mostly gave up this belief and reconciled themselves to the fact that the world probably wasn't going to end imminently (see 2 Peter 3:1-10, the last book of the New Testament to be written), politics still wasn't high on the agenda because the state was largely anti-Christian and Christians simply weren't in a practical position to think about political matters. When they did think about such things, they generally restricted themselves to bilious (though not exactly unjustified) attacks upon the immorality and bloodthirstiness of the Roman state in general and its pagan connotations in particular.
When Christianity became official in the fourth century, everything changed, and the Christians found that political theory was now not only possible but an urgent necessity; and so we find people like Ambrose arguing that the officers of the state (such as the emperor) are subject to officers of the church (such as himself). The result of this was the first two great works of Christian politics - Augustine of Hippo's
City of God and Orosius of Braga's
History against the pagans.
So there's no reason, in a Christian context, why ethics can't lead into politics, and in practice it has done ever since the fourth century; it's just that before then, special considerations (the supposed imminence of the eschaton in the first century, and the hostility of the state in the second and third) prevented it from doing so.
What made a war just according to Augustine?
Augustine believed that there are three main criteria for a just war: just cause, proper authority, and right intention. All three of these had to be met for a war to count as just.
There is a
just cause if the war is undertaken to bring about some greater good, such as the defence of a nation, the establishment of lasting peace or better conditions, and so on.
A war is undertaken with
proper authority if it is declared by public authorities who are charged with maintaining the peace – in other words, a government as opposed to a private group.
There is
right intention if the war is undertaken for a right purpose – in other words, if the war not only
has a “just cause”, but is intentionally pursued
for that “just cause”. So Augustine thinks that there is right intention if the war is undertaken to restore peace or correct some grave injustice. If it’s done to seize territory or take revenge upon another nation then the right intention is lacking, and it is therefore an unjust war (even if in fact it brings about greater good).
Modern Catholic teaching adds three other criteria: last resort, probability of success, and proportionality.
A war is undertaken as a
last resort if all other channels for resolving the problem have been exhausted.
There needs to be some reasonable
probability of success if the worthwhile goals of the war are to balance out the suffering it will bring.
And finally, the damage caused by the war must be
proportional to the desirability of its aims. It would be wrong to go to war to bring about a modest improvement to the world if that war caused many people to suffer.
So in modern Catholic teaching, all six of these criteria must be satisfied for a war to count as just. For example, the Vatican opposed the Iraq war because it felt that even though there might arguably be a just cause, the war was not taken as a last resort, and the intention behind it was questionable. It has also traditionally opposed guerilla or rebel movements, even where the cause and intention are just, because they are not pursued by the proper authority (although the Vatican’s teaching on the justifiability of rebellion is rather flexible; Aquinas argued that a rebellion was acceptable if the whole people rose up against tyranny with one voice).
These criteria are sometimes called the
ius ad bellum – the justice for war – as opposed to the
ius in bello – the justice in war.
Ius in bello is all about how to conduct a war once you’re in it, and it has two main criteria: non-combatant immunity (it is never right to kill or injure civilians on purpose, no matter what the justification) and proportionality (you mustn’t do more damage and harm than you must in order to achieve your goals). So it’s perfectly possible to have a war which is a just war – in the sense of meeting the six criteria of
ius ad bellum and being justly declared – but which is not justly pursued, because it does not meet the criteria for
ius in bello. For example, the British war against Germany in WWII might be considered a just war, but it was unjustly pursued when German cities were bombed and civilians killed. The Second Vatican Council explicitly condemned the bombing of civilians in WWII, including the bombing of German cities and the use of nuclear weapons over Japan. The council also stressed the desirability of peaceful actions even where war might be justified, and praised the principle of non-violent action. On this view, war might be justified if your country is invaded by a hostile aggressor, and the invaded country would have the right to resist, but even so, a non-violent response might still be better. So the church now generally takes a more strongly pro-peace stance than it has in previous centuries.
Jesus was in the company of people from prostitutes to publicans, the lowest classes who were considered scum. Doesn't that show some sense of equality?
Not necessarily. George III used to wander the countryside chatting to farmers and peasants, but he didn't think they were equal to him; he just thought they were worthwhile to talk to. Similarly, Jesus' acceptance of prostitutes and tax-collectors indicates many things: the fact that he was happy to talk to those considered outcasts; the fact that he seems not to have been judgemental when talking to those considered sinners; the fact that he doesn't even seem to have been particularly interested in exhorting them to repent. It doesn't indicate that he thought they were equal to everyone else. I should think that he probably did think that - or, at least, he didn't think that being a sinner makes you unequal with someone else - but in itself it doesn't prove it.
