 …outside of all these spheres, Catholics posit the Empyrean heaven, that is to say, the heaven of flame or the luminous heaven; and they assert that it is motionless by having within itself, with respect to each of its parts, all that its matter wants. This is the reason for the extremely rapid movement of the Prime Mover: through the exceedingly fervent desire of each part of the ninth heaven (which is right next to that one) to be united with each part of that most divine and tranquil heaven, it revolves within it with so much desire that its speed is practically incomprehensible. And tranquil and peaceful is the place of that supreme Deity which alone completely sees itself. This is the place of the blessed spirits, according to the Holy Church, which cannot tell lies; and Aristotle also seems to hold this view, to anyone who follows what he is saying, in the first book of On Heaven and Earth. This heaven is the overarching edifice of the universe, in which all the universe is enclosed, and outside of which nothing exists; and it is not in any place but was formed alone in the First Mind, which the Greeks call Protonoe. This is the magnificence of which the Psalmist spoke, when he says to God: “Elevated above the heavens is your magnificence.”
