Faustus speaks these lines near the end of his opening soliloquy. In this speech, he considers various fields of study one by one, beginning with logic and proceeding through medicine and law. Seeking the highest form of knowledge, he arrives at theology and opens the Bible to the New Testament, where he quotes from Romans and the first book of John. He reads that “[t]he reward of sin is death,” and that “[i]f we say we that we have no sin, / Faustus has blind spots; he sees what he wants to see rather than what is really there. This blindness is apparent in the very next line of his speech: having turned his back on heaven, he pretends that “[t]hese metaphysics of magicians, / And necromantic books are heavenly.” He thus inverts the cosmos, making black magic “heavenly” and religion the source of “everlasting death.”
