The reason the Athenians rejected Paul was because he taught a bodily resurrection, not an allegory

He declared it then to be of such a character as the Pharisees had admitted it, and such as the Lord had Himself maintained it, and such too as the Sadducees refused to believe it—such refusal leading them indeed to an absolute rejection of the whole verity. Nor had the Athenians previously understood Paul to announce any other resurrection. They had, in fact, derided his announcement; but they would have indulged no such derision if they had heard from him nothing but the restoration of the soul, for they would have received that as the very common anticipation of their own native philosophy.

The Platonists and philosophers were wrong about the soul but had vague beginnings of truth

It is satisfactory, however, that the no less important philosophy of Pythagoras and Empedocles, and the Plantonists, take the contrary view, and declare the soul to be immortal; affirming, moreover, in a way which most nearly approaches (to our own doctrine), that the soul actually returns into bodies, although not the same bodies, and not even those of human beings invariably:  thus Euphorbus is supposed to have passed into Phythagoras, and Homer into a peacock. They firmly pronounced the soul’s renewal to be in a body, (deeming it) more tolerable to change the quality (of the corporeal state) than to deny it wholly: they at least knocked at the door of truth, although they entered not. Thus the world, with all its errors, does not ignore the resurrection of the dead.

Humanism is irrational

The humanist’s faith is based on his belief that nonrational causes cause rational beings (humans with minds) who are themselves composed entirely of the nonrational, and yet are somehow able to step outside of that nonrationality and reason to the conclusion that everything is material and therefore nonrational. Yet, if the nonrational material universe is “the whole show,” the humanist could never actually know if he is truly rational or only a nonrational material product with the illusion of rationality.

What is more reasonable to believe, that the nonrational produces the rational; or that a rational being (God) created other rational beings (humans) and a world founded on rational principles that can therefore be understood by these rational beings? The humanist must borrow from the theistic, Christian worldview, which can account for rationality. It is ironic that humanists often accuse Christians of possessing blind faith that the nonrational can produce the rational. Christianity gives birth to science, while humanism only gives birth to blindness.
