St. Gregory, Bishop of Nazianzen, called the Theologian:
ORATION XXVIII (Second Theological Oration)

Translated by Charles Gordon Browne and James Edward Swallow

Paragraphs 1-3: THE ASCENT OF MOUNT SINAI

I. In the former Discourse we laid down clearly with respect to the Theologian, both what sort of character he ought to bear, and on what kind of subject he may philosophize, and when, and to what extent. We saw that he ought to be, as far as may be, pure, in order that light may be apprehended by light; and that he ought to consort with serious men, in order that his word be not fruitless through falling on an unfruitful soil; and that the suitable season is when we have a calm within from the whirl of outward things; so as not like madmen to lose our breath; and that the extent to which we may go is that to which we have ourselves advanced, or to which we are advancing.

Since then these things are so, and we have broken up for ourselves the fallows of Divinity [Jer. 4:3], so as not to sow upon thorns [Matt. 13:7], and have made plain the face of the ground [Isa. 28:25], being moulded and moulding others by Holy Scripture ... let us now enter upon Theological questions, setting at the head thereof the Father, the Son, and the Holy Ghost, of Whom we are to treat; that the Father may be well pleased, and the Son may help us, and the Holy Ghost may inspire us; or rather that one illumination may come upon us from the One God, One in diversity, diverse in Unity, wherein is a marvel.

II. Now when I go up eagerly into the Mount [Ex. 24:1] -or, to use a truer expression, when I both eagerly long, and at the same time am afraid (the one through my hope and the other through my weakness) to enter within the Cloud, and hold converse with God, for so God commands; if any be an Aaron, let him go up with me, and let him stand near, being ready, if it must be so, to remain outside the Cloud. But if any be a Nadab or an Abihu, or of the Order of the Elders, let him go up indeed, but let him stand afar off, according to the value of his purification. But if any be of the multitude, who are unworthy of this height of contemplation, if he be altogether impure let him not approach at all,[Ex. 19:14] , for it would be dangerous to him; but if he be at least temporarily purified, let him remain below and listen to the Voice alone, and the trumpet, [Ex. 19:16-18], the bare words of piety, and let him see the Mountain smoking and lightening, a terror at once and a marvel to those who cannot get up. But if any is an evil and savage beast, and altogether incapable of taking in the subject matter of Contemplation and Theology, let him not hurtfully and malignantly lurk in his den among the woods, to catch hold of some dogma or saying by a sudden spring, and to tear sound doctrine to pieces by his misrepresentations, but let him stand yet afar off and withdraw from the Mount, or he shall be stoned and crushed, and shall perish miserably in his wickedness. For to those who are like wild beasts true and sound discourses are stones. If he be a leopard let him die with his spots, [Jer. 13:23]. If a ravening and roaring lion, seeking what he may devour [1 Pet. 5:8] of our souls or of our words; or a wild boar, trampling under foot the precious and translucent pearls of the Truth [Matt. 7:6]; or an Arabian and alien wolf, [Jer. 5:6 LXX], or one keener even than these in tricks of argument; or a fox, that is a treacherous and faithless soul, changing its shape according to circumstances or necessities, feeding on dead or putrid bodies, or on little vineyards [Cant. 11:15 LXX] when the large ones have escaped them; or any other carnivorous beast, rejected by the Law as unclean for food or enjoyment; our discourse must withdraw from such and be engraved on solid tables of stone, and that on both sides because the Law is partly visible, and partly hidden; the one part belonging to the mass who remain below, the other to the few who press upward into the Mount.

III. What is this that has happened to me, O friends, and initiates, and fellow-lovers of the truth? I was running to lay hold on God, and thus I went up into the Mount, and drew aside the curtain of the Cloud, and entered away from matter and material things, and as far as I could I withdrew within myself. And then when I looked up, I scarce saw the back parts of God, [Ex. 33:23]; although I was sheltered by the Rock, the Word that was made flesh for us. And when I looked a little closer, I saw, not the First and unmingled Nature, known to Itself --- to the Trinity, I mean; not That which abideth within the first veil, [Ex. 26:31], and is hidden by the Cherubim; but only that Nature, which at last even reaches to us. And that is, as far as I can learn, the Majesty, or as holy David calls it, the Glory [Ps. 8:1] which is manifested among the creatures, which It has produced and governs. For these are the Back Parts of God, which He leaves behind Him, as tokens of Himself like the shadows and reflection of the sun in the water, which shew the sun to our weak eyes, because we cannot look at the sun himself, for by his unmixed light he is too strong for our power of perception. In this way then shalt thou discourse of God; even wert thou a Moses and a god to Pharaoh, [Ex. 4:2]; even wert thou caught up like Paul to the Third Heaven, [2 Cor. 12:2], and hadst heard unspeakable words; even wert thou raised above them both, and exalted to Angelic or Archangelic place and dignity. For though a thing be all heavenly, or above heaven, and far higher in nature and nearer to God than we, yet it is farther distant from God, and from the complete comprehension of His Nature, than it is lifted above our complex and lowly and earthward sinking composition.
