History

 * For some Christian history in relation to the events in-universe see the Story timeline.

Regardless of the fact that the Christianity originated as a single religion, according to Index, since politics have entered the religion, divisions began to appear in the religion, eventually culminating in several different factions with their own beliefs and paths, even when they worship the same god.

Because of this rift, the churches lost their connection with each other and evolved in their own ways, and attained their own personalities, based on the country's attributes and various other conditions.

Christianity is the current age that dominates the world of Toaru Majutsu no Index, however, it has been predicted that once Aleister Crowley's Book of the Law is used, the age of the Relgion of the Cross will end.
