XXVI.  To this I may compare the case of Theology Theology is here used in a restricted sense, as denoting simply the doctrine of the Deity of the Son or Logos.  It is very frequently used in this limited sense; examples of which may readily be found in Gregory of Nyssa, Basil, Chrysostom, and others.  A similar use occurs in Orat. XXXVIII., c. 8, in which passage θεολογία is contrasted with οἰκονομία, the doctrine of our Lord’s Divinity with that of the Incarnation. except that it proceeds the reverse way.  For in the case by which I have illustrated it the change is made by successive subtractions; whereas here perfection is reached by additions.  For the matter stands thus.  The Old Testament proclaimed the Father openly, and the Son more obscurely.  The New manifested the Son, and suggested the Deity of the Spirit.  Now the Spirit Himself dwells among us, and supplies us with a clearer demonstration of Himself.  For it was not safe, when the Godhead of the Father was not yet acknowledged, plainly to proclaim the Son; nor when that of the Son was not yet received to burden us further (if I may use so bold an expression) with the Holy Ghost; lest perhaps people might, like men loaded with food beyond their strength, and presenting eyes as yet too weak to bear it to the sun’s light, risk the loss even of that which was within the reach of their powers; but that by gradual additions, and, as David says, Goings up, and advances and progress from glory to glory, Ps. lxxxiv. 7, and 2 Cor. iii. 18. the Light of the Trinity might shine upon the more illuminated.  For this reason it was, I think, that He gradually came to dwell in the Disciples, measuring Himself out to them according to their capacity to receive Him, at the beginning of the Gospel, after the Passion, after the Ascension, making perfect their powers, being breathed upon them, and appearing in fiery tongues.  And indeed it is by little and little that He is declared by Jesus, as you will learn for yourself if you will read more carefully.  I will ask the Father, He says, and He will send you another Comforter, even the spirit of Truth. John xiv. 16, 17.  This He said that He might not seem to be a rival God, or to make His discourses to them by another authority.  Again, He shall send Him, but it is in My Name.  He leaves out the I will ask, but He keeps the Shall send, John xvi. 7. then again, I will send,—His own dignity.  Then shall come, Ib. xvi. 8. the authority of the Spirit.
