Faith then is, so to speak, a compendious knowledge of the essentials; but knowledge is the sure and firm demonstration of what is received by faith, built upon faith by the Lord’s teaching, conveying us on to unshaken conviction and certainty. And, as it seems to me, the first saving change is that from heathenism to faith, as I said before; and the second, that from faith to knowledge. And this latter passing on to love, thereafter gives a mutual friendship between that which knows and that which is known. And perhaps he who has already arrived at this stage has attained equality with the angels. At any rate, after he has reached the final ascent in the flesh, he still continues to advance, as is fit, and presses on through the holy Hebdomad into the Father’s house, to that which is indeed the Lord’s abode. (_c_) Clement of Alexandria, _Stromata_, V, 11. (MSG, 9:102, 106.) The piety of the Christian Gnostic. The sacrifice acceptable with God is unchanging alienation from the body and its passions. This is the really true piety. And is not philosophy, therefore, rightly called by Socrates the meditation on death? For he who neither employs his eyes in the exercise of thought nor draws from his other senses, but with pure mind applies himself to objects, practises the true philosophy.… It is not without reason, therefore, that in the mysteries which are to be found among the Greeks lustrations hold the first place; as also the laver among the barbarians. After these are the minor mysteries, which have some foundation for instruction and preparation for what is to follow. In the great mysteries concerning the universe nothing remains to be learned, but only to contemplate and comprehend with the mind nature and things. We shall understand the more of purification by confession, and of contemplation by analysis, advancing by analysis to the first notion, beginning with the properties underlying it; abstracting from the body its physical properties, taking away the dimension of depth, then of breadth, and then of length. For the point which remains is a unit, so to speak, having position; from which, if we abstract position, there is the conception of unity. If, then, we abstract all that belongs to bodies and things called incorporeal, we cast ourselves into the greatness of Christ, and thence advancing into immensity by holiness, we may reach somehow to the conception of the Almighty, knowing not what He is, but knowing what He is not. And form and motion, or standing, or a throne or place, or right hand or left, are not at all to be conceived as belonging to the Father of the universe, although it is so written. For what each of these signifies will be shown in the proper place. The First Cause is not then in space, but above time and space and name and conception. (_d_) Origen, _De Principiis_, I, 2:2. (MSG, 11:130.)
