I see. Monotheism aside, the difference between our worlds in this case is the structure of religion and the hegemony involved. While my world has different countries and nations, most that reside within them fall under the Christian religion. That faith is organized, with ranks of priests, a hierarchy, and a priest in charge called the pope who is chosen by their god to lead the church. There is a general expectation that Christians obey the teachings of the church as they are interpreted by the priests.

[Alucard's gaze falls back to the bible.] Their god is concerned with morality, and judges you in the afterlife on the topic. That earns you either eternal reward or punishment, the Bible you were given is the guide from where the teachings and reasonings derive from. What you do in your life counts either as a good act or a sin, and what qualifies as sin is really anything the church doesn't approve of.

[As an example:] Murder is a sin, defrauding your neighbor is a sin, generally being a dick is a sin. Magic - usually called witchcraft - is a sin, by their account. Usually it falls to ordinary courts to met out punishments, but spiritual crimes, which magic falls under, is closer to their jurisdictions, as are general heresies and such. They burn heretics and mages alive. It's a point about the afterlife and the eternal flames of their Hell.
