Christianity and Greek Philosophy

Copyright © 1995, R.J. Kilcullen.


Christianity has had, still has, an important influence in politics and in political thought; and in the part of this course from Augustine to Locke we need to talk about it. In this course I do not assume that you all know about Christianity; some of you are Jews or Muslims, or non-religious. So when I talk about it I will try to explain from scratch. I believe I present Christianity sympathetically, but let me say that I am an atheist, and I reject some of the essential Christian beliefs as false.

In the lecture Philosophy from Aristotle to Augustine I sketched out the various schools of philosophy between Aristotle and Augustine. This was the intellectual world into which Christianity came. How did its message sound to the philosophers? Paul went to Athens: 'Some also of the Epicurean and Stoic philosophers met him... So Paul, standing in the middle of the Areopagus said: "Men of Athens..."' - and went on to suggest that he had come to tell them of the unknown God, who made the world, takes a close interest in the doings of mankind, and will judge the world, through a man (i.e. Jesus Christ) whom God has vouched for by raising him from the dead (alluding to the Christian belief that after death Jesus arose again alive from the dead). 'Now when they heard of the resurrection of the dead, some mocked; but others said, "We will hear you again about this".' (Acts 17:16-34.)

Paul elsewhere refers to Greek philosophy, the wisdom of the Greeks, in ironical contrast with 'the foolishness of God': what the Christians believe, especially perhaps about the resurrection of the body, seems foolish to the philosophers. Cf. 1 Cor. 1:17- 2:13, 3:19, 15:12-20 ('How can some of you say that there is no resurrection of the dead?').

So the belief that the body will rise again was one important difference between the doctrine of the Christians and that of the various schools of philosophy. The Epicureans held that body and soul are collections of atoms, finally dispersed at death (or shortly afterwards). The Stoics also were materialists; they held that after death the body becomes earth, and the soul returns to the central fire. The Platonists held that the soul is immortal; the Christians held that the whole human being is immortal, that the body will rise again - which to philosophers of all Schools sounded either ridiculous, or like a possibly interesting innovation.

Let us list some other points about Christianity that invite comparison with Greek philosophy:

The points of comparison so far are in favour of Christianity. Let me mention a few minuses.

So as a philosophy of life Christianity has pluses and minuses. On the reaction of non-Christian philosophers to Christianity see M.V. Anastos, 'Porphyry's Attack on the Bible', in his Studies in Byzantine Intellectual History (London, Variorum, 1979), [DF/531/.A5]; and P. Courcelle, 'Anti-Christian Arguments and Christian Platonism: From Arnobius to St Ambrose', in A. Momigliano (ed.), The Conflict Between Paganism and Christianity in the Fourth Century (BR/205/.M6).

Political Implications of Christianity

After Augustine among Christians in western europe there were two competing ideas. One that the city of man even at its best will be nothing more than a peace-keeping organisation, keeping peace in the minimal sense that the elect and the reprobate can agree upon. At its worst it will be latrocinium (robbery), and that is what it usually is. Pride and desire for honour are the best motives likely to operate; from a religious point of view pride is damnable, but it may foster civil peace. This is the explanation of what is best in Roman history; at their best the Romans sought honour, reputation, and for that reason often did what justice and virtue would also require (cf. Republic, 363).

The other idea, competing with this, is the Platonic notion of government by philosophers, which came into western Europe as embodied in the ethics and politics of Aristotle. The philosophers now are the religious experts - after God's revelation, human wisdom has been superseded by wisdom based on this revelation. So the leaders of the Christian Church should play the role in which Plato cast the philosophers. Theology, Christian wisdom, is architectonic in relation to politics. Salvation is the work of God and the Church, and the civil government cannot directly contribute to this work; but it can indirectly, by repressing outward sin, repressing rival religions and philosophies, contributing funds and supplies, and so on. So to say that religion is architectonic in relation to politics means that it is up to the Church to determine what contributions the state can and should make to religion, and that carrying out these determinations is the overriding duty of the civil ruler.

These two competing ideas run through medieval political thought - that the state exists to keep the peace, minimally defined, and that it exists to further the salvation of its subjects, as far as that can be secured by the state under the direction of the Church. Medieval writers on political philosophy were theologians, and you might expect them to favour the second idea, that religion directs the state. Many of them did. But many of them defended the other view, that the state exists for this- worldly purposes, which it pursues autonomously. The conflict between these two views is the chief topic of part 2 of the course.
