On the question why certain Names in the Holy Scriptures are changed (176-180)

On which account that pride which was wise in its own conceit, having been thrown down, and the feeling which is devoted to God having been raised in its place, and being established around the only unalterable being, he, immediately laughing, said in his mind, "Shall a child be born to one who is a hundred years old, and shall Sarrah, who is ninety years old, have a child?"

Do not fancy, my good friend, that that word, "he said" not with his mouth but "in his mind," [*] has been added for no especial use; on the contrary, it is inserted with great accuracy and propriety. Why so? Because it seems by his saying, "Shall a child be born to him who is a hundred years old?" that he had a doubt about the birth of Isaac, in which he was previously stated to believe; as what was predicted a little before showed, speaking thus, "This child shall not be thy heir, but he who shall come out of thee;" and immediately afterward he says, "Abraham believed in the Lord, and it was counted to him for righteousness."

Since then it was not consistent for one who had already believed to doubt, he has represented the doubt as of no long continuance, extending only as far as the mouth and the tongue, and stopping there at the mind which is endowed with such celerity of motion; for, says the scripture, "he said in his mind," which nothing, and no person ever so celebrated for swiftness of foot, could ever be able to outstrip, since it outruns even all the winged natures;

on which account the most illustrious of all the Greek poets appears to me to have said:— "Swift as a winged bird or fleeter thought." [*] Showing by these words the exceeding speed of its promptitude, placing the thought after the winged bird as a sort of climax; for the mind advances at the same moment to very many things and bodies, hurrying on with indescribable impetuosity, and without a moment’s lapse of time it speeds at once to the borders of both earth and sea, bringing together and dividing infinite magnitudes by a single word; and at the same time it soars to such a height above the earth, that it penetrates [*] [*] [*]

For the fervid and glowing heat of that region does not suffer it to rest tranquil; on which account, overleaping many things, it is borne far beyond every boundary perceptible by the outward senses, to that which is compounded of ideas and appearances by the law of kindred. On which account in the good man there is a slight change, indivisible, unapportionable, not perceptible by the outward senses, but only by the intellect, and being in a manner independent of them.
