This is only a short answer space. I think the Christian motif comes in the form of salvation, mercy, and redemption. Hell is eternal, but so is heaven. For a Christian, all that is necessary to be saved from eternal damnation is acceptance of Jesus Christ's grace. Even after signing away his soul to the devil, Faustus has the option of repentance that will save him from hell. But once he has committed himself to his own damnation, Faustus seems unable to change his course. While Christianity seems to accept even a deathbed repentance as acceptable for the attainment of salvation, Marlowe plays with that idea, possibly rejecting it for his own thematic purposes. (See analysis of 5.2-end of the play).
