Origen

“ Celsus accordingly, as not understanding the doctrine relating to the Spirit of God (“for the natural man receiveth not the things of the Spirit of God, for they are foolishness unto him; neither can he know them, because they are spiritually discerned” [1] ) , weaves together (such a web) as pleases himself, [2] imagining that we, in calling God a Spirit, differ in no respect in this particular from the Stoics among the Greeks, who maintain that “God is a Spirit, diffused through all things, and containing all things within Himself.” ”
