"God is incomprehensible, and incapable of being measured.[...]"

"God is incomprehensible, and incapable of being measured. For whatever be the knowledge which we are able to obtain of God, either by perception or reflection, we must of necessity believe that He is by many degrees far better than what we perceive Him to be. For, as if we were to see any one unable to bear a spark of light, or the flame of a very small lamp, and were desirous to acquaint such a one, whose vision could not admit a greater degree of light than what we have stated, with the brightness and splendour of the sun, would it not be necessary to tell him that the splendour of the sun was unspeakably and incalculably better and more glorious than all this light which he saw? So our understanding, when shut in by the fetters of flesh and blood, and rendered, on account of its participation in such material substances, duller and more obtuse, although, in comparison with our bodily nature, it is esteemed to be far superior, yet, in its efforts to examine and behold incorporeal things, scarcely holds the place of a spark or lamp. But among all intelligent, that is, incorporeal beings, what is so superior to all others—so unspeakably and incalculably superior—as God, whose nature cannot be grasped or seen by the power of any human understanding, even the purest and brightest? But it will not appear absurd if we employ another similitude to make the matter clearer.  Our eyes frequently cannot look upon the nature of the light itself—that is, upon the substance of the sun; but when we behold his splendour or his rays pouring in, perhaps, through windows or some small openings to admit the light, we can reflect how great is the supply and source of the light of the body. So, in like manner. the works of Divine Providence and the plan of this whole world are a sort of rays, as it were, of the nature of God, in comparison with His real substance and being." (Origen, De Pr. 1.1.5-6)
