In his own words on Isaiah

• Isaiah 40:12

  For such an indication of God's infinity the words "I Am that I Am" were clearly adequate; but, in addition, we needed to apprehend the operation of His majesty and power. For while absolute existence is peculiar to Him Who, abiding eternally, had no beginning in a past however remote, we hear again an utterance worthy of Himself issuing from the eternal and Holy God, Who says, "Who holdeth the heaven in His palm and the earth in His hand," and again, "The heaven is My throne and the earth is the footstool of My feet. What house will ye build Me or what shall be the place of My rest?" The whole heaven is held in the palm of God, the whole earth grasped in His hand. Now the word of God, profitable as it is to the cursory thought of a pious mind, reveals a deeper meaning to the patient student than to the momentary hearer. For this heaven which is held in the palm of God is also His throne, and the earth which is grasped in His hand is also the footstool beneath His feet. This was not written that from throne and footstool, metaphors drawn from the posture of one sitting, we should conclude that He has extension in space, as of a body, for that which is His throne and footstool is also held in hand and palm by that infinite Omnipotence. It was written that in all born and created things God might be known within them and without, overshadowing and indwelling, surrounding all and interfused through all, since palm and hand, which hold, reveal the might of His external control, while throne and footstool, by their support of a sitter, display the subservience of outward things to One within Who, Himself outside them, encloses all in His grasp, yet dwells within the external world which is His own. In this wise does God, from within and from without, control and correspond to the universe; being infinite He is present in all things, in Him Who is infinite all are included.

  ON THE TRINITY 1:6

• Isaiah 64:4

  But it may be argued that the Apostle was not inspired by the Spirit of prophecy when he borrowed these prophetic words; that he was only interpreting at random the words of another man, and though, no doubt, everything the Apostle says of himself comes to him by revelation from Christ, yet his knowledge of the words of Isaiah is only derived from the book. I answer that in the beginning of that utterance in which it is said that the servants of the true God shall bless Him and swear by Him, we read this adoration by the prophet: "From everlasting we have not heard, nor have our eyes seen God, except Thee, and Thy works which Thou wilt do for them that await Thy mercy." Isaiah says that he has seen no God but Him. For he did actually see the glory of God, the mystery of Whose taking flesh from the Virgin he foretold. And if you, in your heresy, do not know that it was God the Only-begotten Whom the prophet saw in that glory, listen to the Evangelist: "These things said Esaias, when he saw His glory, and spake of Him." The Apostle, the Evangelist, the Prophet combine to silence your objections. Isaiah did see God; even though it is written, "No one hath seen God at any time, save the Only-begotten Son Who is in the bosom of the Father; He hath declared Him," it was God Whom the prophet saw. He gazed upon the Divine glory, and men were filled with envy at such honour vouchsafed to his prophetic greatness. For this was the reason why the Jews passed sentence of death upon him.
