What has Athens to do with Jerusalem? The early church refused to be influenced too heavily by pagan philosophy.

From all these, when the apostle would restrain us, he expressly names philosophy as that which he would have us be on our guard against. Writing to the Colossians, he says, “See that no one beguile you through philosophy and vain deceit, after the tradition of men, and contrary to the wisdom of the Holy Ghost.” He had been at Athens, and had in his interviews (with its philosophers) become acquainted with that human wisdom which pretends to know the truth, whilst it only corrupts it, and is itself divided into its own manifold heresies, by the variety of its mutually repugnant sects. What indeed has Athens to do with Jerusalem? What concord is there between the Academy and the Church? what between heretics and Christians? Our instruction comes from “the porch of Solomon,” who had himself taught that “the Lord should be sought in simplicity of heart.” Away with all attempts to produce a mottled Christianity of Stoic, Platonic, and dialectic composition! We want no curious disputation after possessing Christ Jesus, no inquisition after enjoying the gospel! With our faith, we desire no further belief. For this is our palmary faith, that there is nothing which we ought to believe besides.

All demonstration is preceded by self-evident knowledge

Now demonstration differs from analysis. For each one of the points demonstrated, is demonstrated by means of points that are demonstrated; those having been previously demonstrated by others; till we get back to those which are self-evident, or to those evident to sense and to understanding; which is called Analysis. But demonstration is, when the point in question reaches us through all the intermediate steps. The man, then, who practices demonstration, ought to give great attention to the truth, while he disregards the terms of the premisses, whether you call them axioms, or premisses, or assumptions. Similarly, also, special attention must be paid to what suppositions a conclusion is based on; while he may be quite careless as to whether one choose to term it a conclusive or syllogistic proposition.

For I assert that these two things must be attended to by the man who would demonstrate— to assume true premisses, and to draw from them the legitimate conclusion, which some also call the inference, as being what is inferred from the premisses.

Now in each proposition respecting a question there must be different premisses, related, however, to the proposition laid down; and what is advanced must be reduced to definition. And this definition must be admitted by all. But when premisses irrelevant to the proposition to be established are assumed, it is impossible to arrive at any right result; the entire proposition— which is also called the question of its nature— being ignored.

In all questions, then, there is something which is previously known—that which being self-evident is believed without demonstration; which must be made the starting point in their investigation, and the criterion of apparent results.

Difference between syllogism and demonstration

So that there is a compound advantage of demonstration: from its assuming, for the proof of points in question, true premisses, and from its drawing the conclusion that follows from them. If the first have no existence, but the second follow from the first, one has not demonstrated, but syllogized.

For, to draw the proper conclusion from the premisses, is merely to syllogize. But to have also each of the premisses true, is not merely to have syllogized, but also to have demonstrated.

God gave both the Hebrew covenants and Greek philosophy

And further, that the same God that furnished both the Covenants was the giver of Greek philosophy to the Greeks, by which the Almighty is glorified among the Greeks, he shows.

…But as the proclamation [of the Gospel] has come now at the fit time, so also at the fit time were the Law and the Prophets given to the Barbarians, and Philosophy to the Greeks, to fit their ears for the Gospel.

The Greeks had vague references to the Trinity

For I pass over Plato; he plainly, in the Epistle to Erastus and Coriscus, is seen to exhibit the Father and Son somehow or other from the Hebrew Scriptures, exhorting in these words: “In invoking by oath, with not illiterate gravity, and with culture, the sister of gravity, God the author of all, and invoking Him by oath as the Lord, the Father of the Leader, and author; whom if ye study with a truly philosophical spirit, ye shall know.” And the address in the Timœus calls the creator, Father, speaking thus: “Ye gods of gods, of whom I am Father; and the Creator of your works.” So that when he says, “Around the king of all, all things are, and because of Him are all things; and he [or that] is the cause of all good things; and around the second are the things second in order; and around the third, the third,” I understand nothing else than the Holy Trinity to be meant; for the third is the Holy Spirit, and the Son is the second, by whom all things were made according to the will of the Father.

Greek philosophy was separate fragments of truth

So, then, the barbarian and Hellenic philosophy has torn off a fragment of eternal truth not from the mythology of Dionysus, but from the theology of the ever-living Word. And He who brings again together the separate fragments, and makes them one, will without peril, be assured, contemplate the perfect Word, the truth. Therefore it is written in Ecclesiastes: “And I added wisdom above all who were before me in Jerusalem; and my heart saw many things; and besides, I knew wisdom and knowledge, parables and understanding. And this also is the choice of the spirit, because in abundance of wisdom is abundance of knowledge.”
