Clement of Alexandria

It is, then, our purpose to prove that the Gnostic alone is holy and pious, and worships the true God in a manner worthy of Him; and that worship meet for God is followed by loving and being loved by God. He accordingly judges all excellence to be honourable according to its worth; and judges that among the objects perceived by our senses, we are to esteem rulers, and parents, and every one advanced in years; and among subjects of instruction, the most ancient philosophy and primeval prophecy; and among intellectual ideas, what is oldest in origin, the timeless and unoriginated First Principle, and Beginning of existence-the Son-from whom we are to learn the remoter Cause, the Father, of the universe, the most ancient and the most beneficent of all; not capable of expression by the voice, but to be reverenced with reverence, and silence, and holy wonder, and supremely venerated; declared by the Lord, as far as those who learned were capable of comprehending, and understood by those chosen by the Lord to acknowledge; "whose senses," says the apostle, "were exercised."
