it deals with the themes at the heart of Christianity’s understanding of the world. First, there is the idea of sin, which Christianity defines as acts contrary to the will of God. In making a pact with Lucifer, Faustus commits what is in a sense the ultimate sin: not only does he disobey God, but he consciously and even eagerly renounces obedience to him, choosing instead to swear allegiance to the devil. In a Christian framework, however, even the worst deed can be forgiven through the redemptive power of Jesus Christ, God’s son, who, according to Christian belief, died on the cross for humankind’s sins. Thus, however terrible Faustus’s pact with Lucifer may be, the possibility of redemption is always open to him. All that he needs to do, theoretically, is ask God for forgiveness. The play offers countless moments in which Faustus considers doing just that, urged on by the good angel on his shoulder or by the old man in scene 12—both of whom can be seen either as emissaries of God, personifications of Faustus’s conscience, or both.
