He who commends the nature of the soul as the supreme good, and condemns the nature of the flesh as evil, at once both carnally desires the soul, and carnally flies the flesh, because he feels thus from human vanity, not from divine truth.
As the soul is the life of the body, so God is the life of the soul. As therefore the body perishes when the soul leaves it, so the soul dies when God departs from it.
Thus the good christian should beware of mathematicians and all those who make false prophecies, however much they may in fact speak the truth; lest, being in league with the devil, they may deceive errant souls into making common cause.

And how great soever a mass of building one may wish and design to place above it, the greater the building is to be, the deeper does he dig his foundation.
