Answer:
Fundamentalism.
Step-by-step explanation:
Christian fundamentalism was a movement that arose within American and British Protestantism in late 19th and early 20th century against theological modernism. Its aim was to revive the traditional Christian beliefs so that developments in the social sciences and natural sciences can accommodated.
The fundamentalist confirmed core christian beliefs such as Christ's Virgin birth and Resurrection. It became a notable phenomenon in 20th century. Fundamentalist worship practices were influenced by revivalism and included sermon with congregational prayer and singing.
Although fundamentalists are not ascetics but they do observe prohibition such as smoking and drinking alcohol and attending plays, movies and dance.
