Divine Simplicity
For when the eyes are spoken of, it is implied that He sees all things; and when the ear, it is set forth that He hears all things; and when the finger, a certain energy of His will is opened up; and when the nostrils, His recognition of prayers is shown forth as of odours; and when the hand, it is proved that He is the author of every creature; and when the arm, it is announced that no nature can withstand the power of His arm; and when the feet it is unfolded that He fills all things, and that there is not any place where God is not. For neither members nor the offices of members are needful to Him to whose sole judgment, even unexpressed, all things serve and are present. For why should He require eyes who is Himself the light? or why should He ask for feet who is everywhere? or why should He wish to go when there is nowhere where He can go beyond Himself? or why should He seek for hands whose will is, even when silent, the architect for the foundation of all things? He needs no ears who knows the wills that are even unexpressed; or for what reason should He need a tongue whose thought is a command? These members assuredly were necessary to men, but not to God, because man’s design would be ineffectual if the body did not fulfil the thought. Moreover, they are not needful to God, whose will the works attend not so much without any effort, as that the works themselves proceed simultaneously with the will. Moreover, He Himself is all eye, because He all sees; and all ear, because He all hears; and all hand, because He all works; and all foot, because He all is everywhere. For He is the same, whatever it is. He is all equal, and all everywhere. For He has not in Him any diversity in Himself, being simple.

In What Sense is God a Spirit?
For we find it to be written that God is called Love , and yet from this the substance of God is not declared to be Love ; and that He is called Light , while in this is not the substance of God. But the whole that is thus said of God is as much as can be said, so that reasonably also, when He is called a Spirit, it is not all that He is which is so called; but so that, while men’s mind by understanding makes progress even to the Spirit itself, being already changed in spirit, it may conjecture God to be something even greater through the Spirit. …For if “the things which God hath prepared for them that love Him, neither eye hath seen, nor ear hath heard, nor the heart of man, nor even his mind has perceived;” what and how great is He Himself who promises these things, in understanding which both the mind and nature of man have failed! Finally, if you receive the Spirit as the substance of God, you will make God a creature. …But these things are rather used as figures than as being so in fact. For as, in the Old Testament, God is for this reason called Fire , that fear may be struck into the hearts of a sinful people, by suggesting to them a Judge; so in the New Testament He is announced as Spirit, that, as the Renewer and Creator of those who are dead in their sins, He may be attested by this goodness of mercy granted to those that believe.

The Dual Nature of Christ
Let them, therefore, who read that Jesus Christ the Son of man is man, read also that this same Jesus is called also God and the Son of God. For in the manner that as man He is of Abraham, so also as God He is before Abraham himself. And in the same manner as He is as man the “Son of David,” so as God He is proclaimed David’s Lord. And in the same manner as He was made as man “under the law,” so as God He is declared to be “Lord of the Sabbath.” And in the same manner as He suffers, as man, the condemnation, so as God He is found to have all judgment of the quick and dead. And in the same manner as He is born as man subsequent to the world, so as God He is manifested to have been before the world. And in the same way as He was begotten as man of the seed of David, so also the world is said to have been ordained by Him as God. And in the same way as He was as man after many, so as God He was before all. And in the same manner as He was as man inferior to others, so as God He was greater than all. And in the same manner as He ascended as man into heaven, so as God He had first descended thence. And in the same manner as He goes as man to the Father, so as the Son in obedience to the Father He shall descend thence. So if imperfections in Him prove human frailty, majesties in Him affirm divine power.

Jacob Wrestled with Christ
“Because thou hast prevailed with God, and art powerful with men.” For which reason the same Jacob, perceiving already the force of the Mystery, and apprehending the authority of Him with whom he had wrestled, called the name of that place in which he had wrestled, the Vision of God … “For I have seen,” said he, “God face to face, and my soul has been saved.”
He saw God, with whom he wrestled as with a man; but still indeed he held the man as a conqueror, though as an inferior he asked a blessing as from God. Thus he wrestled with God and with man; and thus truly was that struggle prefigured, and in the Gospel was fulfilled, between Christ and the people of Jacob
For against this man Jacob’s people struggled, in which struggle Jacob’s people was found to be the more powerful, because against Christ it gained the victory of its iniquity: at which time, on account of the crime that it committed, hesitating and giving way, it began most sorely to halt in the walk of its own faith and salvation; and although it was found the stronger, in respect of the condemnation of Christ, it still needs His mercy, still needs His blessing.
