<span>Then rushing sudden on his prostrate prize, To spoil the carcase fierce Patroclus flies: Swift as a lion, terrible and bold, That sweeps the field, depopulates the fold

The Bible verse that Faust quotes is meant to teach Christians that all people are sinners and that sin leads to death. HOWEVER- Christians believe that God forgives sinners who repent. The versus are meant to cause people to repent, not despair- so it shows he doesn't understand Christianity
D. Faustus does not truly understand Christianity
