4 You now, as I think, understand how the word perhaps is used here, in case any weigher of words and poiser of syllables, as if to show his knowledge of Latin, finds fault with a word which the Word of God spoke; and by blaming the Word of God, remain not eloquent, but mute. For who is there that speaks as does the Word which was in the beginning with God? Do not consider these words as we use them, and from these wish to measure that Word which is God. You hear the Word indeed, and despisest it; hear God and fear Him: “In the beginning was the Word.”
Thou referrest to the usage of your conversation, and sayest within yourself, What is a word? What mighty thing is a word? It sounds and passes away; after beating the air, it strikes the ear and is no more. Hear further: “The Word was with God;” remained, did not by sounding pass away. Perhaps thou still despisest it: “The Word was God.” With yourself, O man, a word in your heart is a different thing from sound; but the word that is with you, in order to pass to me, requires sound for a vehicle as it were.
It takes to itself sound, mounts it as a vehicle, runs through the air, comes to me and yet does not leave you. But the sound, in order to come to me, left you and yet did not stay with me. Now has the word that was in your heart also passed away with the passing sound? You spoke your thought; and, that the thought which was hid with you might come to me, you sounded syllables; the sound of the syllables conveyed your thought to my ear; through my ear your thought descended into my heart, the intermediate sound flew away: but that word which took to itself sound was with you before you sounded it, and is with me, because you sounded it, without quitting you.
Consider this, thou nice weigher of sounds, whoever thou be. Thou despisest the Word of God, thou who comprehendest not the word of man.
