In his address on the Areopagus Paul proclaims the name of the resurrected Christ to the Gentile covenant-breakers, would-be fugitives from divine judgment. Paul does not place himself on their level in order with them to investigate the nature of being and knowledge in general, to discover whether the God of Abraham, Isaac, and Jacob might possibly exist. He tells them straight out that what they claim not to know, he knows. He tells them that their so-called ignorance is culpable, for God is as near to them as their own selves. He tells them, therefore, to repent of their worship of idols, to turn to the living God, lest they stand without the robes of righteousness before the resurrected Lord Christ on the day of judgment.
… Paul knew that the Greeks could not identify themselves truly in terms of their philosophy. “Chaos” and “Old Night” were their only substitutes for what Paul told them of the origin and destiny of the world. They tried various combinations of ultimate rationality (unity) and ultimate chance (diversity) in terms such as “form” and “matter” to take the place of creation and providence, but to no satisfaction. Even so, Paul could not prove to the Greeks in their sense of the word “prove,” that what they believed was foolishness and what he believed was “good sense.” Paul could not adopt the principles of the “free” first Adam to “prove” the principles of the Second Adam. Paul recognized, as did his Greek audience, that his ideas were, all of them, foolishness to the non-Christian mind. The Greeks would not believe any single one of them, much less all of them in their proper relation to each other, unless by the regeneration of the Holy Spirit they were given eyes with which to see the whole truth of God in Christ. Paul knew that the natural man, like Xantippe who is said to have kept on clipping her fingers even though these fingers were all that was left of her above the water, will keep on saying that Christ is wrong and that Satan is right so long as he has breath except the Spirit in mercy give him light and life.
