Isaiah 40:26

As for their other assertion, that God's knowledge cannot comprehend things infinite, it only remains for them to affirm, in order that they may sound the depths of their impiety, that God does not know all numbers. For it is very certain that they are infinite; since, no matter of what number you suppose an end to be made, this number can be, I will not say, increased by the addition of one more, but however great it be, and however vast be the multitude of which it is the rational and scientific expression, it can still be not only doubled, but even multiplied. Moreover, each number is so defined by its own properties, that no two numbers are equal. They are therefore both unequal and different from one another; and while they are simply finite, collectively they are infinite. Does God, therefore, not know numbers on account of this infinity; and does His knowledge extend only to a certain height in numbers, while of the rest He is ignorant? Who is so left to himself as to say so? Yet they can hardly pretend to put numbers out of the question, or maintain that they have nothing to do with the knowledge of God; for Plato, their great authority, represents God as framing the world on numerical principles: and in our books also it is said to God, "Thou hast ordered all things in number, and measure, and weight." The prophet also says, "Who bringeth out their host by number." And the Saviour says in the Gospel, "The very hairs of your head are all numbered." Far be it, then, from us to doubt that all number is known to Him "whose understanding," according to the Psalmist, "is infinite." The infinity of number, though there be no numbering of infinite numbers, is yet not incomprehensible by Him whose understanding is infinite. […]

In many places in scripture is the phrase "Lift up your eyes" set forth by the divine word, urging us to elevate and raise our thoughts and our vision, which is cast down and stooped, unable to fully look up and to rise on high; just as in Isaiah: "Lift up your eyes on high and see: who has created these things?" And the Savior, when about to proclaim the Beatitudes to those gathered on the plain, lifted up his eyes to his disciples and said, "Blessed are they" and so forth; for no true disciple of Jesus is below, just as neither is the one resting in Abraham's bosom. Thus the rich man, being in torments, lifted up his eyes and saw Abraham and Lazarus in his bosom. Moreover, the woman "bowed together and could in no wise lift up herself" was straightened by Jesus so that she might lift up her eyes. And no one involuntarily afflicted or attached to the flesh or immersed in material things has kept the commandment that says, "Lift up your eyes," whence such a one shall not see the fields even if they are "already white to harvest." Yet again, no one working the deeds of the flesh has lifted up their eyes.

[Isaiah] says, look at the sun, the moon, the movement of the stars, the cycle of the year, the changing of the seasons, the regular succession of night and day. For this is what [Isaiah] has added: "He who brings forth by number the order …

Do not think that I ignore the designs of your souls, God says through Isaiah, and do not believe that you escape my view when you hold perverse reasonings. This passage lets [us] see clearly that he has also thrown the accusation of polytheism against …

So with such great power and majesty of the Creator, how can you compare God to the likeness of a creature? And do you not rather understand the Creator from the magnitude of the creatures? If you do not believe in words, believe at least in your own eyes; and consider the power of the Lord from the service of the heavens and all the elements. He summons their army, that is, the heavens, in number; and he calls them all by name, and it is understood, the stars.
