On the Holy Trinity — Historical footnotes

16. For it is one thing to make and administer the creature from the innermost and highest turning-point of causation, which He alone does who is God the Creator; but quite another thing to apply some operation from without in proportion to the strength and faculties assigned to each by Him, so that what is created may come forth into being at this time or at that, and in this or that way. For all these things in the way of original and beginning have already been created in a kind of texture of the elements, but they come forth when they get the opportunity. For as mothers are pregnant with young, so the world itself is pregnant with the causes of things that are born; which are not created in it, except from that highest essence, where nothing either springs up or dies, either begins to be or ceases. But the applying from without of adventitious causes, which, although they are not natural, yet are to be applied according to nature, in order that those things which are contained and hidden in the secret bosom of nature may break forth and be outwardly created in some way by the unfolding of the proper measures and numbers and weights which they have received in secret from Him “who has ordered all things in measure and number and weight:” this is not only in the power of bad angels, but also of bad men, as I have shown above by the example of agriculture.

18. But He only is the creator who is the chief former of these things. Neither can any one be this, unless He with whom primarily rests the measure, number, and weight of all things existing; and He is God the one Creator, by whose unspeakable power it comes to pass, also, that what these angels were able to do if they were permitted, they are therefore not able to do because they are not permitted. For there is no other reason why they who made frogs and serpents were not able to make the most minute flies, unless because the greater power of God was present prohibiting them, through the Holy Spirit; which even the magicians themselves confessed, saying, “This is the finger of God.” But what they are able to do by nature, yet cannot do, because they are prohibited; and what the very condition of their nature itself does not suffer them to do; it is difficult, nay, impossible, for man to search out, unless through that gift of God which the apostle mentions when he says, “To another the discerning of spirits.” For we know that a man can walk, yet that he cannot do so if he is not permitted; but that he cannot fly, even if he be permitted. So those angels, also, are able to do certain things if they are permitted by more powerful angels, according to the supreme commandment of God; but cannot do certain other things, not even if they are permitted by them; because He does not permit from whom they have received such and such a measure of natural powers: who, even by His angels, does not usually permit what He has given them power to be able to do.
