The Oration is thus analysed by Abbe Benoît:
"After an exordium which is full of the enthusiasm and joy which such a subject naturally inspires the Orator recommends his hearers to celebrate the Festival by a pious gladness, and by hearing the Word of God; and not as the heathen celebrated their feasts, by profane amusements and all kinds of excess. He will try to satisfy their desires by speaking to them of God. God is infinite, ineffable, eternal, the Sovereign Good. He created the Angels in the beginning out of goodness. The fall of the Angels was followed by the creation of the material world. Man too fell, and God shewed His mercy even in the punishment. He used various means to raise him again; and at length He came Himself. Then the speaker forcibly argues against those who misuse the infinite condescension of the Word to contest His Godhead; he rapidly traces the principal features of His Life--at once human and Divine; and ends with a recommendation to his hearers to imitate in all things the Life of Christ, so that they may have a share in His Kingdom in Heaven."
It is considered one of the best of Gregory's discourses. "By the grandeur of the plan," says Benoît, "the elevation of the ideas, and the rich fund of doctrine, this discourse is incontestably one of S. Gregory's most remarkable efforts."
I. Christ is born, glorify ye Him. Christ from heaven, go ye out to meet Him. Christ on earth; be ye exalted. Sing unto the Lord all the whole earth; [3843] and that I may join both in one word, Let the heavens rejoice, and let the earth be glad, for Him Who is of heaven and then of earth. Christ in the flesh, rejoice with trembling and with joy; with trembling because of your sins, with joy because of your hope. Christ of a Virgin; O ye Matrons live as Virgins, that ye may be Mothers of Christ. Who doth not worship Him That is from the beginning? Who doth not glorify Him That is the Last?
II. Again the darkness is past; again Light is made; again Egypt is punished with darkness; again Israel is enlightened by a pillar. [3844] The people that sat in the darkness of ignorance, let it see the Great Light of full knowledge. [3845] Old things are passed away, behold all things are become new. [3846] The letter gives way, the Spirit comes to the front. The shadows flee away, the Truth comes in upon them. Melchisedec is concluded. [3847] He that was without Mother becomes without Father (without Mother of His former state, without Father of His second). The laws of nature are upset; the world above must be filled. Christ commands it, let us not set ourselves against Him. O clap your hands together all ye people, [3848] because unto us a Child is born, and a Son given unto us, Whose Government is upon His shoulder (for with the Cross it is raised up), and His Name is called The Angel of the Great Counsel of the Father. [3849] Let John cry, Prepare ye the way of the Lord: [3850] I too will cry the power of this Day. He Who is not carnal is Incarnate; the Son of God becomes the Son of Man, Jesus Christ the Same yesterday, and to-day, and for ever. [3851] Let the Jews be offended, let the Greeks deride; [3852] let heretics talk till their tongues ache. Then shall they believe, when they see Him ascending up into heaven; and if not then, yet when they see Him coming out of heaven and sitting as Judge.
III. Of these on a future occasion; for the present the Festival is the Theophany or Birth-day, for it is called both, two titles being given to the one thing. For God was manifested to man by birth. On the one hand Being, and eternally Being, of the Eternal Being, above cause and word, for there was no word before The Word; and on the other hand for our sakes also Becoming, that He Who gives us our being might also give us our Well-being, or rather might restore us by His Incarnation, when we had by wickedness fallen from wellbeing. The name Theophany is given to it in reference to the Manifestation, and that of Birthday in respect of His Birth.
IV. This is our present Festival; it is this which we are celebrating to-day, the Coming of God to Man, that we might go forth, [3853] or rather (for this is the more proper expression) that we might go back to God--that putting off the old man, we might put on the New; and that as we died in Adam, so we might live in Christ, [3854] being born with Christ and crucified with Him and buried with Him and rising with Him. [3855] For I must undergo the beautiful conversion, and as the painful succeeded the more blissful, so must the more blissful come out of the painful. For where sin abounded Grace did much more abound; [3856] and if a taste condemned us, how much more doth the Passion of Christ justify us? Therefore let us keep the Feast, not after the manner of a heathen festival, but after a godly sort; not after the way of the world, but in a fashion above the world; not as our own but as belonging to Him Who is ours, or rather as our Master's; not as of weakness, but as of healing; not as of creation, but of re-creation.
V. And how shall this be? Let us not adorn our porches, nor arrange dances, nor decorate the streets; let us not feast the eye, nor enchant the ear with music, nor enervate the nostrils with perfume, nor prostitute the taste, nor indulge the touch, those roads that are so prone to evil and entrances for sin; let us not be effeminate in clothing soft and flowing, whose beauty consists in its uselessness, nor with the glittering of gems or the sheen of gold [3857] or the tricks of colour, belying the beauty of nature, and invented to do despite unto the image of God; Not in rioting and drunkenness, with which are mingled, I know well, chambering and wantonness, since the lessons which evil teachers give are evil; or rather the harvests of worthless seeds are worthless. Let us not set up high beds of leaves, making tabernacles for the belly of what belongs to debauchery. Let us not appraise the bouquet of wines, the kickshaws of cooks, the great expense of unguents. Let not sea and land bring us as a gift their precious dung, for it is thus that I have learnt to estimate luxury; and let us not strive to outdo each other in intemperance (for to my mind every superfluity is intemperance, and all which is beyond absolute need),--and this while others are hungry and in want, who are made of the same clay and in the same manner.
VI. Let us leave all these to the Greeks and to the pomps and festivals of the Greeks, who call by the name of gods beings who rejoice in the reek of sacrifices, and who consistently worship with their belly; evil inventors and worshippers of evil demons. But we, the Object of whose adoration is the Word, if we must in some way have luxury, let us seek it in word, and in the Divine Law, and in histories; especially such as are the origin of this Feast; that our luxury may be akin to and not far removed from Him Who hath called us together. Or do you desire (for to-day I am your entertainer) that I should set before you, my good Guests, the story of these things as abundantly and as nobly as I can, that ye may know how a foreigner can feed [3858] the natives of the land, and a rustic the people of the town, and one who cares not for luxury those who delight in it, and one who is poor and homeless those who are eminent for wealth?
We will begin from this point; and let me ask of you who delight in such matters to cleanse your mind and your ears and your thoughts, since our discourse is to be of God and Divine; that when you depart, you may have had the enjoyment of delights that really fade not away. And this same discourse shall be at once both very full and very concise, that you may neither be displeased at its deficiencies, nor find it unpleasant through satiety.
VII. God always was, [3859] and always is, and always will be. Or rather, God always Is. For Was and Will be are fragments of our time, and of changeable nature, but He is Eternal Being. And this is the Name that He gives to Himself when giving the Oracle to Moses in the Mount. For in Himself He sums up and contains all Being, having neither beginning in the past nor end in the future; like some great Sea of Being, limitless and unbounded, transcending all conception of time and nature, only adumbrated by the mind, and that very dimly and scantily...not by His Essentials, but by His Environment; one image being got from one source and another from another, and combined into some sort of presentation of the truth, which escapes us before we have caught it, and takes to flight before we have conceived it, blazing forth upon our Master-part, even when that is cleansed, as the lightning flash which will not stay its course, does upon our sight...in order as I conceive by that part of it which we can comprehend to draw us to itself (for that which is altogether incomprehensible is outside the bounds of hope, and not within the compass of endeavour), and by that part of It which we cannot comprehend to move our wonder, and as an object of wonder to become more an object of desire, and being desired to purify, and by purifying to make us like God; [3860] so that when we have thus become like Himself, God may, to use a bold expression, hold converse with us as Gods, being united to us, and that perhaps to the same extent as He already knows those who are known to Him. The Divine Nature then is boundless and hard to understand; and all that we can comprehend of Him is His boundlessness; even though one may conceive that because He is of a simple nature He is therefore either wholly incomprehensible, or perfectly comprehensible. For let us further enquire what is implied by "is of a simple nature." For it is quite certain that this simplicity is not itself its nature, just as composition is not by itself the essence of compound beings.
VIII. And when Infinity is considered from two points of view, beginning and end (for that which is beyond these and not limited by them is Infinity), when the mind looks to the depth above, not having where to stand, and leans upon phenomena to form an idea of God, it calls the Infinite and Unapproachable which it finds there by the name of Unoriginate. And when it looks into the depths below, and at the future, it calls Him Undying and Imperishable. And when it draws a conclusion from the whole it calls Him Eternal (aionios). For Eternity (haion) is neither time nor part of time; for it cannot be measured. But what time, measured by the course of the sun, is to us, that Eternity is to the Everlasting, namely, a sort of time-like movement and interval co-extensive with their existence. This, however, is all I must now say about God; for the present is not a suitable time, as my present subject is not the doctrine of God, but that of the Incarnation. But when I say God, I mean Father, Son, and Holy Ghost. For Godhead is neither diffused beyond these, so as to bring in a mob of gods; nor yet is it bounded by a smaller compass than these, so as to condemn us for a poverty-stricken conception of Deity; either Judaizing to save the Monarchia, or falling into heathenism by the multitude of our gods. For the evil on either side is the same, though found in contrary directions. This then is the Holy of Holies, [3861] which is hidden even from the Seraphim, and is glorified with a thrice repeated Holy, [3862] meeting in one ascription of the Title Lord and God, as one of our predecessors has most beautifully and loftily pointed out.
IX. But since this movement of self-contemplation alone could not satisfy Goodness, but Good must be poured out and go forth beyond Itself to multiply the objects of Its beneficence, for this was essential to the highest Goodness, He first conceived the Heavenly and Angelic Powers. And this conception was a work fulfilled by His Word, and perfected by His Spirit. And so the secondary Splendours came into being, as the Ministers of the Primary Splendour; whether we are to conceive of them as intelligent Spirits, or as Fire of an immaterial and incorruptible kind, or as some other nature approaching this as near as may be. I should like to say that they were incapable of movement in the direction of evil, and susceptible only of the movement of good, as being about God, and illumined with the first rays from God--for earthly beings have but the second illumination; but I am obliged to stop short of saying that, and to conceive and speak of them only as difficult to move because of him, [3863] who for his splendour was called Lucifer, but became and is called Darkness through his pride; and the apostate hosts who are subject to him, creators of evil [3864] by their revolt against good and our inciters.
