36. Gentile writers, following ours as it were through shadows, because they could not imbibe the truth of the Spirit, have pointed out in their verses that the Spirit within nourishes heaven and earth, and the glittering orbs of moon and stars. Virg. Æn. VI. 724. So they deny not that the strength of creatures exists through the Spirit, are we who read this to deny it? But you think that they refer to a Spirit produced of the air. If they declared a Spirit of the air to be the Author of all things, do we doubt that the Spirit of God is the Creator of all things?
