Plotinus, could you explain how Christian thoughts on war went from Tertullian saying for instance this:
To Saint Ambrose seemingly justifying or at least recognizing that cohabitation with war wasn't as intolerable as one might think:
Before finally arriving at Saint Augustine who seems to me to have accepted that war while not desirable, was at least acceptable under a certain set of circumstances. Which he would lay out in his theory of Just War with things like this:
I guess I'm just interested in the theological permutations that allowed that kind of, what seems to me, radical changes in the religious foundations of Christianity to occur.
That's a good question. The obvious answer is that Tertullian was writing at a time when Christians were a minority being persecuted by the state, while Ambrose and Augustine were writing at a time when Christianity was more or less the de facto state religion. Clearly a persecuted religion has the luxury of complete pacifism, just as a political party without a hope of being elected has the luxury of making whatever policies it likes - whereas a religion that is allied to the state lacks this luxury, just as a party that's actually in power may find that idealistic policies are no longer workable.
I think that's true to some extent. However, the situation is also more complex, as usual. For one thing, Tertullian was not always representative. He was an extremist even by the standards of second-century Christianity, whose moral rigorism was so great that he eventually gave up on the mainstream church and joined the highly ascetic Montanist sect. The passage you quote was written in a book attacking not pagan soldiers but Christian ones. There were plenty of Christians who joined the army; Tertullian thought they were wrong to do so. It seems that there was a spectrum of opinions of this. Some Christians believed that the military was completely wrong and at odds with Christianity, and there are stories of men choosing to be martyred rather than join the army. Others believed it was quite compatible with being a Christian, provided they did not join in with any military ceremonies which were too pagan. Tertullian's
On the crown describes a Christian soldier who refused to wear a triumphal crown, on the grounds that it was pagan. The usual view, I think, was that a military career was acceptable provided that a Christian did not become an officer (since he would have to order others to kill) or an executioner. Christianity was, at that stage, very much a pacifist religion, but it was also more pragmatic than one might expect about these things.
By the time of Ambrose and especially Augustine, Christianity had obviously become wedded to the state to some degree, and emperors were now Christians (and yet perfectly happy to order executions, at least if people like Constantius II are anything to go by). So there is an element of inevitable loss of idealism associated with a greater position of power. However, it's important to bear in mind that Augustine's criteria for a "just war" are quite strict, and furthermore, they were made stricter later. In fact today they are so strict that the Catholic Church is bound to consider almost all wars unjust. So it's not a simple matter of idealism giving way to a cynical excusing of war. Although there certainly was change in Christians' attitude to war, I don't think it was
that great a change - at least not during late antiquity. You will see, after all, that Augustine's emphasis is upon the evils of aggressive warfare, and in that he was perfectly in line with earlier Christian moralists such as Cyprian or indeed John of Patmos.
What's a good set of ten books to read if the Bible is too long? A friend took me up on an offer to read them if I would list ten summary books, and here's what I came up with on short notice:
OT: Genesis, Isaiah, Samuel, Job, Daniel
NT: Luke, Acts, John, Romans, Revelation
My pastor's suggestions (from memory): "Samuel is two books. Cut out Job, it's too difficult for a beginner. Switch Isaiah for Hosea, it's shorter and more focused. You'll want Exodus as well as Genesis, so I think Daniel has to go. Drop Revelations, put in Ephesians or Corinthians instead."
I'd like a third opinion, and maybe some commentary on picking for a beginners' introduction vs. picking for representativity if they don't expect to read more later.
I don't really know enough about the Bible to say, especially with the Old Testament. You'd surely want Genesis and Exodus, and perhaps Chronicles? Esther is quite fun but rather silly. Ruth is a nice book. I don't know enough about any of the prophets to be able to tell them apart, although Isaiah seems pretty important (and you get three authors for the price of one there...). I think Daniel might be a good choice to help with understanding various bits of the New Testament.
With the New Testament, I'd say Matthew, John, Acts, Romans, 1 Corinthians, Hebrews, 1 John, and Revelation. Er, which is too many. So drop John, Hebrews, and 1 John.
I'd be nervous about including John: I think it's important to modern Christianity, but it's too uncredible.
It's important to all Christianity - but what's the aim of this anyway? It's not much more incredible than Genesis or Exodus. If the aim is to get an overview of the Bible then whether a book is believable or not is really neither here nor there.
