Origen

“ For, without a clear preliminary definition of these terms, it might be maintained that, if all things were made through the Logos, and evil is a part of all things, then the whole matter of sin, and everything that is wicked, that these also were made through the Logos. But this we must regard as false. There is nothing absurd in thinking that creatures were made through the Logos, and also that men’s brave deeds have been done through Him, and all the useful acts of those who are now in bliss; but with the sins and misfortunes of men it is otherwise. ”

“ Over against good is evil or wickedness, and over against Him who is that which is not, whence it follows that evil and wickedness are that which is not. This, perhaps, is what has led some to affirm that the devil is not created by God. In respect that he is the devil he is not the work of God, but he who is the devil is a created being, and as there is no other creator but our God, he is a work of God. It is as if we should say that a murderer is not a work of God, while we may say that in respect he is a man, God made him. ”

“ Now some have held that since evil is not based in the constitution of things—for it did not exist at the beginning and at the end it will have ceased—that, therefore, the evils of which we spoke are the Nothing; and as some of the Greeks say that genera and forms, such as the (general) animal and the man, belong to the category of Nothings, so it has been supposed that all that is not of God is Nothing, and has not even obtained through the Word the subsistence it appears to have. ”
