For just as, had the sun not been in existence, night would have brooded over the universe notwithstanding the other luminaries of heaven; so, had we nor known the Word, and been illuminated by Him; we should have been nowise different from fowls that are being fed, fattened in darkness, and nourished for death. Let us then admit the light, that we may admit God; let us admit the light, and become disciples to the Lord.
Clement of Alexandria
Exhortation to the Heathen
Chapter XI
