Isaiah 45:9

For we, who do not know at all what the future has in store and see merely our present circumstances, misjudge what will profit us. God … sees what is to come as if it were present. These prophecies are addressed, however, to those who make themselves God's judges. To them may also fittingly be cited those words of Scripture, "shall the clay say to the potter" and so forth.How shall we not shun a person who legislates in opposition to the laws of God and issues decrees in opposition to the works of providence, whereas he dares not breathe a word against human laws? Therefore, leaving such exaggerations, or, to speak more truly, blasphemies, on one side, let us demonstrate the error of denying particular providence while acknowledging universal and general providence.

Just as the potter models anew the vase of broken clay, [God] says, for my part, I will make you better than at first. "Will the plowman plow the earth all day?" This comes back to saying it is not effective to use chastisement continually, for the cultivator does not keep tearing up the soil without ceasing. "Woe to him who disputes with the One who formed him!" "Shall the clay say to the potter, What are you doing that you do not work, nor have hands? Shall the thing formed answer him that formed it?" Since there were many in that epoch, and now likewise, who concern themselves ill-advisedly with divine providence and who attempt to study inquisitively the cause for the occurrence of wars, of periods of sterility of the soil, of premature deaths and of all the things of this nature, it is understandable that he should first of all deplore those who demand an accounting from the Creator of the universe. He, then, has skillfully closed their mouth by the image of the clay and the potter: the clay does not demand an accounting from the one who worked it regarding his rest or his work. In the same way is it no more fitting to occupy yourself rudely with divine matters, for you are precisely the clay. But there is between me and the potter the greatest difference there could be: the potter, though he is the creator of the utensil of clay, is nevertheless, on his part, the firstborn of the clay, whereas I possess an uncreated nature. Yet the clay does not say a word but supports the modeling that the potter wishes to impose on it, while you pay no attention to my providence.

Likewise, the common Jewish people rejected the grace that was given them and found it unacceptable; for they resisted, as I have said, the teachings of Christ.… "For I desire to refashion you," he says, "into something better, to remake you into something superior through a spiritual birth which, of course, is the one through water and the Spirit; but you foolishly resist my plans. Did the clay," he says, "ever reproach the potter for not having a skillful hand, or for not knowing how to give shape to what he holds in his hands? Nor," he says, "does the one who is about to be born put a question to his own father, 'Will you give birth?' How is it, then, that you, who are like clay in the potter's hands, and do not know at all how your spiritual rebirth will take place, are not afraid of being cantankerous? And why do you not realize you ought to leave it to me, as to a craftsman and father, how to do these things?" … Therefore, it is necessary to [yield] to what God says. He himself knows the way of his own works, and what he fashioned is not subject to prying, and what transcends our understanding should be given the honor of unquestioning faith.One must also understand that the prophet Jeremiah was sent to the house of the potter to see him at work. When the clay collapsed and was reshaped into a different vessel, God said to him: "Can I not do with you as this potter has done, O house of Israel? Behold, just like the clay in the potter's hand, so are you in my hand." Paul, also, explains that we are transformed spiritually into a holy and utterly good life, when he says: "And all of us, with unveiled faces, seeing the glory of the Lord as though reflected in a mirror, are being transformed in to the same image from one degree of glory to another; for this comes from the Lord, the Spirit"8; through whom we are also born again, not any longer of corruptible seed, but through the word of the living God who endures forever.
