They live no longer in the faith of Reason.
But still the heart doth need a language; still
Doth the old instinct bring back the old names."
The Piccolomini, Act II. Scene 4.
As a matter of fact we find the believers in the Greek religion more ready to receive Christianity than were the Jews. All through Asia Minor and Greece Christian churches were planted by Paul; a fact which shows that the ground was somehow prepared for Christianity. It was ready for the monotheism which Paul substituted for their multitude of gods, and for their idolatry and image-worship. The statues had ceased to be symbols, and the minds of the Greeks rested in the image itself. This idolatrous worship Paul condemned, and the people heard him willingly, as he called them up to a more spiritual worship. We think, therefore, that the Greek religion was a real preparation for Christianity. We have seen that it was itself in constant transition; the system of the poets passing into that of the artists, and that of the artists into that of the philosophers; so that the philosophic religion, in turn, was ready to change into a Christian monotheism.
It may be said, since philosophy had undermined the old religion and substituted for it more noble ideas, why did it not take the seat of the dethroned faith, and sufficiently supply its place? If it taught a pure monotheism and profound ethics, if it threw ample and adequate light on the problem of God, duty, and immortality, what more was needed? If ideas are all that we want, nothing more. That Greek philosophy gave way before Christianity shows that it did not satisfy all the cravings of the soul; shows that man needs a religion as well as a religious philosophy, a faith as well as an intellectual system. A religion is one thing, a speculation is a very different thing. The old Greek religion, so long as it was a living faith, was enough. When men really believed in the existence of Olympian Jove, Pallas-Athênê, and Phoebus-Apollo, they had something above them to which to look up. When this faith was disintegrated, no system of opinions, however pure and profound, could replace it. Another faith was needed, but a faith not in conflict with the philosophy which had destroyed polytheism; and Christianity met the want, and therefore became the religion of the Greek-speaking world.
Religion is a life, philosophy is thought; religion looks up, philosophy looks in. We need both thought and life, and we need that the two shall be in harmony. The moment they come in conflict, both suffer. Philosophy had destroyed the ancient simple faith of the Hellenic race in their deities, and had given them instead only the abstractions of thought. Then came the Apostles of Christianity, teaching a religion in harmony with the highest thought of the age, and yet preaching it out of a living faith. Christianity did not come as a speculation about the universe, but as a testimony. Its heralds bore witness to the facts of God's presence and providence, of his fatherly love, of the brotherhood of man, of a rising to a higher life, of a universal judgment hereafter on all good and evil, and of Jesus as the inspired and ascended revealer of these truths. These facts were accepted as realities; and once more the human mind had something above itself solid enough to support it.
Some of the early Christian Fathers called on the heathen poets and philosophers to bear witness to the truth. Clement of Alexandria[266] after quoting this passage of Plato, "around the king of all are all things, and he is the cause of all good things," says that others, through God's inspiration, have declared the only true God to be God. He quotes Antisthenes to this effect: "God is not like to any; wherefore no one can know him from an image." He quotes Cleanthes the Stoic:—
"If you ask me what is the nature of the good, listen:
That which is regular, just, holy, pious,
