IV. And if we must also look at ancient history, I perceive that Enoch, the seventh among our ancestors, was honoured by translation. I perceive also that the twenty-first, Abraham, was given the glory of the Patriarchate, by the addition of a greater mystery. For the Hebdomad thrice repeated brings out this number. And one who is very bold might venture even to come to the New Adam, my God and Lord Jesus Christ, Who is counted the Seventy-seventh from the old Adam who fell under sin, in the backward genealogy according to Luke. And I think of the seven trumpets of Jesus, the son of Nave, and the same number of circuits and days and priests, by which the walls of Jericho were shaken down. And so too the seven compassings of the City; in the same way as there is a mystery in the threefold breathings of Elias, the Prophet, by which he breathed life into the son of the Sareptan widow, and the same number of his floodings of the wood, when he consumed the sacrifice with fire sent from God, and condemned the prophets of shame who could not do the like at his challenge. And the sevenfold looking for the cloud imposed upon the young servant; and Elissæus stretching himself that number of times upon the child of the Shunammite, by which stretching the breath of life was restored. To the same doctrine belongs, I think (if I may omit the seven-stemmed and seven-lamped candlestick of the Temple) that the ceremony of the Priests' consecration lasted seven days; and seven that of the purifying of a leper, and that of the Dedication of the Temple the same number, and that in the seventieth year the people returned from the Captivity; that whatever is in Units may appear also in Decads, and the mystery of the Hebdomad be reverenced in a more perfect number. But why do I speak of the distant past? Jesus Himself who is pure perfection, could in the desert and with five loaves feed five thousand, and again with seven loaves four thousand. And the leavings after they were satisfied were in the first case twelve baskets full, and in the other seven baskets; neither, I imagine, without a reason or unworthy of the Spirit. And if you read for yourself you may take note of many numbers which contain a meaning deeper than appears on the surface. But to come to an instance which is most useful to us on the present occasion, not that for these reasons or others very similar or yet more divine, the Hebrews honour the Day of Pentecost, and we also honour it; just as there are other rites of the Hebrews which we observe...they were typically observed by them, and by us they are sacramentally reinstated. And now having said so much by way of preface about the Day, let us proceed to what we have to say further.
V. We are keeping the feast of Pentecost and of the Coming of the Spirit, and the appointed time of the Promise, and the fulfilment of our hope. And how great, how august, is the Mystery. The dispensations of the Body of Christ are ended; or rather, what belongs to His Bodily Advent (for I hesitate to say the Dispensation of His Body, as long as no discourse persuades me that it is better to have put off the body), and that of the Spirit is beginning. And what were the things pertaining to the Christ? The Virgin, the Birth, the Manger, the Swaddling, the Angels glorifying Him, the Shepherds running to Him, the course of the Star, the Magi worshipping Him and bringing Gifts, Herod's murder of the children, the Flight of Jesus into Egypt, the Return from Egypt, the Circumcision, the Baptism, the Witness from Heaven, the Temptation, the Stoning for our sake (because He had to be given as an Example to us of enduring affliction for the Word), the Betrayal, the Nailing, the Burial, the Resurrection, the Ascension; and of these even now He suffers many dishonours at the hands of the enemies of Christ; and He bears them, for He is longsuffering. But from those who love Him He receives all that is honourable. And He defers, as in the former case His wrath, so in ours His kindness; in their case perhaps to give them the grace of repentance, and in ours to test our love; whether we do not faint in our tribulations and conflicts for the true Religion, as was from of old the order of His Divine Economy, and of his unsearchable judgments, with which He orders wisely all that concerns us. Such are the mysteries of Christ. And what follows we shall see to be more glorious; and may we too be seen. As to the things of the Spirit, may the Spirit be with me, and grant me speech as much as I desire; or if not that, yet as is in due proportion to the season. Anyhow He will be with me as my Lord; not in servile guise, nor awaiting a command, as some think. For He blows where He wills and on whom He wills, and to what extent He wills. Thus we are inspired both to think and to speak of the Spirit.
VI. They who reduce the Holy Spirit to the rank of a creature are blasphemers and wicked servants, and worst of the wicked. For it is the part of wicked servants to despise Lordship, and to rebel against dominion, and to make That which is free their fellow-servant. But they who deem Him God are inspired by God and are illustrious in their mind; and they who go further and call Him so, if to well disposed hearers are exalted; if to the low, are not reserved enough, for they commit pearls to clay, and the noise of thunder to weak ears, and the sun to feeble eyes, and solid food to those who are still using milk; whereas they ought to lead them little by little up to what lies beyond them, and to bring them up to the higher truth; adding light to light, and supplying truth upon truth. Therefore we will leave the more mature discourse, for which the time has not yet come, and will speak with them as follows.
VII. If, my friends, you will not acknowledge the Holy Spirit to be uncreated, nor yet eternal; clearly such a state of mind is due to the contrary spirit— forgive me, if in my zeal I speak somewhat over boldly. If, however, you are sound enough to escape this evident impiety, and to place outside of slavery Him Who gives freedom to yourselves, then see for yourselves with the help of the Holy Ghost and of us what follows. For I am persuaded that you are to some extent partakers of Him, so that I will go into the question with you as kindred souls. Either show me some mean between lordship and servitude, that I may there place the rank of the Spirit; or, if you shrink from imputing servitude to Him, there is no doubt of the rank in which you must place the object of your search. But you are dissatisfied with the syllables, and you stumble at the word, and it is to you a stone of stumbling and a rock of offense; for so is Christ to some minds. It is only human after all. Let us meet one another in a spiritual manner; let us be full rather of brotherly than of self love. Grant us the Power of the Godhead, and we will give up to you the use of the Name. Confess the Nature in other words for which you have greater reverence, and we will heal you as infirm people, filching from you some matters in which you delight. For it is shameful, yes, shameful and utterly illogical, when you are sound in soul, to draw petty distinctions about the sound, and to hide the Treasure, as if you envied it to others, or were afraid lest you should sanctify your own tongue too. But it is even more shameful for us to be in the state of which we accuse you, and, while condemning your petty distinctions of words to make petty distinctions of letters.
