XII.  And therefore He came after Christ, that a Comforter should not be lacking unto us; but Another Comforter, that you might acknowledge His co-equality.  For this word Another marks an Alter Ego, a name of equal Lordship, not of inequality.  For Another is not said, I know, of different kinds, but of things consubstantial.  And He came in the form of Tongues because of His close relation to the Word.  And they were of Fire, perhaps because of His purifying Power (for our Scripture knows of a purifying fire, as any one who wishes can find out), or else because of His Substance.  For our God is a consuming Fire, and a Fire Heb. xii. 20. burning up the ungodly; Deut. iv. 24. though you may again pick a quarrel over these words, being brought into difficulty by the Consubstantiality.  And the tongues were cloven, because of the diversity of Gifts; and they sat to signify His Royalty and Rest among the Saints, and because the Cherubim are the Throne of God.  And it took place in an Upper Chamber (I hope I am not seeming to any one over tedious), because those who should receive it were to ascend and be raised above the earth; for also certain upper chambers Ps. civ. 3. are covered with Divine Waters, Ps. cxlviii. 4. by which the praise of God are sung.  And Jesus Himself in an Upper Chamber gave the Communion of the Sacrament to those who were being initiated into the higher Mysteries, that thereby might be shewn on the one hand that God must come down to us, as I know He did of old to Moses; and on the other that we must go up to Him, and that so there should come to pass a Communion of God with men, by a coalescing of the dignity.  For as long as either remains on its own footing, the One in His Glory ἐπὶ περιοπῆς; Billius renders “In specula sua,” “On His watch tower,” and the meaning is admissible, but the context seems rather to point to the passive sense of Majesty or Glory.  The word is not in the Lexicon, and Suicer does not notice it; but the corresponding adjective has only the passive sense.  Specula, however, is used in the sense of Eminence, but apparently only geographically. the other in his lowliness, so long the Goodness of God cannot mingle with us, and His lovingkindness is incommunicable, and there is a great gulf between, which cannot be crossed; and which separates not only the Rich Man from Lazarus and Abraham’s Bosom which he longs for, but also the created and changing natures from that which is eternal and immutable.
