3 You ought, then, to be informed in the first place, and, those of you who can, to understand, and the others, who cannot as yet understand, to believe, that in that substantial essence, which is God, the senses are not, as if through some material structure of a body, distributed in their appropriate places; as, in the mortal flesh of all animals there is in one place sight, in another hearing, in another taste, in another smelling, and over the whole the sense of touch.
Far be it from us to believe so in the case of that incorporeal and immutable nature. In it, therefore, hearing and seeing are one and the same thing. In this way smelling also is said to exist in God; as the apostle says, “As Christ also has loved us, and has given Himself for us an offering and a sacrifice to God for a sweet-smelling savor.” And taste may be included, in accordance with which God hates the bitter in temper, and spews out of His mouth those who are lukewarm, and neither cold nor hot: and Christ our God says, “My meat is to do the will of Him that sent me.” There is also that divine sense of touch, in accordance with which the spouse says of the bridegroom: “His left hand is under my head, and his right hand shall embrace me.” But these are not in God's case in different parts of the body.
For when He is said to know, all are included: both seeing, and hearing, and smelling, and tasting, and touching; without any alteration of His substance, and without the existence of any material element which is greater in one place and smaller in another: and when there are any such thoughts of God in those even who are old in years, they are the thoughts only of a childish mind.
