XVII. What God is in nature and essence, no man ever yet has discovered or can discover. Whether it will ever be discovered is a question which he who will may examine and decide. In my opinion it will be discovered when that within us which is godlike and divine, I mean our mind and reason, shall have mingled with its Like, and the image shall have ascended to the Archetype, of which it has now the desire. And this I think is the solution of that vexed problem as to “We shall know even as we are known.” But in our present life all that comes to us is but a little effluence, and as it were a small effulgence from a great Light. So that if anyone has known God, or has had the testimony of Scripture to his knowledge of God, we are to understand such an one to have possessed a degree of knowledge which gave him the appearance of being more fully enlightened than another who did not enjoy the same degree of illumination; and this relative superiority is spoken of as if it were absolute knowledge, not because it is really such, but by comparison with the power of that other.
XVIII. Thus Enos “hoped to call upon the Name of the Lord.” Hope was that for which he is commended; and that, not that he should know God, but that he should call upon him. And Enoch was translated, but it is not yet clear whether it was because he already comprehended the Divine Nature, or in order that he might comprehend it. And Noah's glory was that he was pleasing to God; he who was entrusted with the saving of the whole world from the waters, or rather of the Seeds of the world, escaped the Deluge in a small Ark. And Abraham, great Patriarch though he was, was justified by faith, and offered a strange victim, the type of the Great Sacrifice. Yet he saw not God as God, but gave Him food as a man. He was approved because he worshipped as far as he comprehended. And Jacob dreamed of a lofty ladder and stair of Angels, and in a mystery anointed a pillar — perhaps to signify the Rock that was anointed for our sake— and gave to a place the name of The House of God in honour of Him whom he saw; and wrestled with God in human form; whatever this wrestling of God with man may mean...possibly it refers to the comparison of man's virtue with God's; and he bore on his body the marks of the wrestling, setting forth the defeat of the created nature; and for a reward of his reverence he received a change of his name; being named, instead of Jacob, Israel— that great and honourable name. Yet neither he nor any one on his behalf, unto this day, of all the Twelve Tribes who were his children, could boast that he comprehended the whole nature or the pure sight of God.
XIX. To Elias neither the strong wind, nor the fire, nor the earthquake, as you learn from the story, but a light breeze adumbrated the Presence of God, and not even this His Nature. And who was this Elias? The man whom a chariot of fire took up to heaven, signifying the superhuman excellency of the righteous man. And are you not amazed at Manoah the Judge of yore, and at Peter the disciple in later days; the one being unable to endure the sight even of one in whom was a representation of God; and saying, “We are undone, O wife, we have seen God;” speaking as though even a vision of God could not be grasped by human beings, let alone the Nature of God; and the other unable to endure the Presence of Christ in his boat and therefore bidding Him depart; and this though Peter was more zealous than the others for the knowledge of Christ, and received a blessing for this, and was entrusted with the greatest gifts. What would you say of Isaiah or Ezekiel, who was an eyewitness of very great mysteries, and of the other Prophets; for one of these saw the Lord of Sabaoth sitting on the Throne of glory, and encircled and praised and hidden by the sixwinged Seraphim, and was himself purged by the live coal, and equipped for his prophetic office. And the other describes the Cherubic Chariot of God, and the Throne upon them, and the Firmament over it, and Him that showed Himself in the Firmament, and Voices, and Forces, and Deeds. And whether this was an appearance by day, only visible to Saints, or an unerring vision of the night, or an impression on the mind holding converse with the future as if it were the present; or some other ineffable form of prophecy, I cannot say; the God of the Prophets knows, and they know who are thus inspired. But neither these of whom I am speaking, nor any of their fellows ever stood before the Council and Essence of God, as it is written, or saw, or proclaimed the Nature of God.
XX. If it had been permitted to Paul to utter what the Third Heaven contained, and his own advance, or ascension, or assumption there, perhaps we should know something more about God's Nature, if this was the mystery of the rapture. But since it was ineffable, we too will honour it by silence. Thus much we will hear Paul say about it, that we know in part and we prophesy in part. This and the like to this are the confessions of one who is not rude in knowledge, who threatens to give proof of Christ speaking in him, the great doctor and champion of the truth. Wherefore he estimates all knowledge on earth only as through a glass darkly, as taking its stand upon little images of the truth. Now, unless I appear to anyone too careful, and over anxious about the examination of this matter, perhaps it was of this and nothing else that the Word Himself intimated that there were things which could not now be borne, but which should be borne and cleared up hereafter, and which John the Forerunner of the Word and great Voice of the Truth declared even the whole world could not contain.
XXI. The truth then, and the whole Word is full of difficulty and obscurity; and as it were with a small instrument we are undertaking a great work, when with merely human wisdom we pursue the knowledge of the Self-existent, and in company with, or not apart from, the senses, by which we are borne hither and there, and led into error, we apply ourselves to the search after things which are only to be grasped by the mind, and we are unable by meeting bare realities with bare intellect to approximate somewhat more closely to the truth, and to mould the mind by its concepts.
Now the subject of God is more hard to come at, in proportion as it is more perfect than any other, and is open to more objections, and the solutions of them are more laborious. For every objection, however small, stops and hinders the course of our argument, and cuts off its further advance, just like men who suddenly check with the rein the horses in full career, and turn them right round by the unexpected shock. Thus Solomon, who was the wisest of all men, whether before him or in his own time, to whom God gave breadth of heart, and a flood of contemplation, more abundant than the sand, even he, the more he entered into the depth, the more dizzy he became, and declared the furthest point of wisdom to be the discovery of how very far off she was from him. Paul also tries to arrive at, I will not say the nature of God, for this he knew was utterly impossible, but only the judgments of God; and since he finds no way out, and no halting place in the ascent, and moreover, since the earnest searching of his mind after knowledge does not end in any definite conclusion, because some fresh unattained point is being continually disclosed to him (O marvel, that I have a like experience), he closes his discourse with astonishment, and calls this the riches of God, and the depth, and confesses the unsearchableness of the judgments of God, in almost the very words of David, who at one time calls God's judgments the great deep whose foundations cannot be reached by measure or sense; and at another says that His knowledge of him and of his own constitution was marvellous, and had attained greater strength than was in his own power or grasp.
