God has revealed Himself, not in one but in many ways, not only by inspiring the hearts, but by vouchsafing His guidance to all who seek it. "The spirit of man is the candle of the Lord," and it is not religion but apostasy to deny the reality of any of God's revelations of truth to man, merely because they have not descended through a single channel. On the contrary, we ought to hail with gratitude, instead of viewing with suspicion, the enunciation by heathen writers of truths which we might at first sight have been disposed to regard as the special heritage of Christianity. In Pythagoras, and Socrates, and Plato, -in Seneca, Epictetus, and Marcus Aurelius- we see the light of heaven struggling its impeded way through clouds of darkness and ignorance; we thankfully recognize that the souls of men in the Pagan world, surrounded as they were by perplexities and dangers, were yet enabled to reflect, as from the dim surface of silver, some image of what was divine and true; we hail, with the great and eloquent Bossuet, "THE CHRISTIANITY OF NATURE."
