Wide and insurmountable is the interval that divides and fences off uncreated from created nature

Yet, if we weigh even their comprehension with the majesty of Him Who really is, it may be that if any one should venture to say that even their power of understanding is not far superior to our own weakness, his conjecture would fall within the limits of probability, for wide and insurmountable is the interval that divides and fences off uncreated from created nature (πολὺ γὰρ τὸ μέσον καὶ ἀδιεξίτητον, ᾦ πρὸς τὴν κτιστὴν οὐσίαν ἠ ἄκτιστος φύσις διατετείχισται). The latter is limited, the former not. The latter is confined within its own boundaries according to the pleasure of its Maker. The former is bounded only by infinity. The latter stretches itself out within certain degrees of extension, limited by time and space: the former transcends all notion of degree, baffling curiosity from every point of view. In this life we can apprehend the beginning and the end of all things that exist, but the beatitude that is above the creature admits neither end nor beginning, but is above all that is connoted by either, being ever the same, self-dependent, not travelling on by degrees from one point to another in its life; for there is no participation of other life in its life, such that we might infer end and beginning; but, be it what it may, it is life energizing in itself, not becoming greater or less by addition or diminution. For increase has no place in the infinite, and that which is by its nature passionless excludes all notion of decrease. (Con. Eun. 2.1.69) (NPNF, 257)
