Logos grew to mean the inward constitution as well as the outward form of thought, and consequently became the expression of exact thought,—which is exact because it corresponds to universal and unchanging principles,—and reached its highest exaltation in becoming not only the reason in man, but the reason in the universe,—the Divine Logos, the thought of God, the Son of God, God himself.
