No sooner do I conceive of the One than I am illumined by the splendour of the Three; no sooner do I distinguish them than I am carried back to the One. When I think of any One of the Three, I think of Him as the whole, and my eyes are filled, and the greater part of what I am thinking of escapes me. I cannot grasp the greatness of that One so as to attribute a greater greatness to the rest. When I contemplate the Three together, I see but one torch, and cannot divide or measure out the uncreated light.
