Origen

“ Indeed, if one considers the multitude of speculation and knowledge about God, beyond the power of human nature to take in, beyond the power, perhaps, of all originated beings except Christ and the Holy Spirit, then one may know how God is surrounded with darkness, because the discourse is hid in ignorance which would be required to tell in what darkness He has made His hiding-place when He arranged that the things concerning Him should be unknown and beyond the grasp of knowledge. ”

“ There is a Divine Darkness Which is Not Evil, and Which Ultimately Becomes Light.
In connection with this subject it is necessary for us to point out that darkness is not to be understood, every time it is mentioned, in a bad sense; Scripture speaks of it sometimes in a good sense. The heterodox have failed to observe this distinction, and have accordingly adopted most shameful doctrines about the Maker of the world, and have indeed revolted from Him, and addicted themselves to fictions and myths. We must, therefore, show how and when the name of darkness is taken in a good sense. ”

“ I might add a still stranger feature of this darkness which is praised, namely, that it hastens to the light and overtakes it, and so at last, after having been unknown as darkness, undergoes for him who does not see its power such a change that he comes to know it and to declare that what was formerly known to him as darkness has now become light. ”
