Type the term for a group that is like a sect in its separation from the mainstream, but additionally claims to have received a new, supernatural revelation.

The correct answer is cult.

In religion, the term cult refers to a group of people who are venerating a saint (or some other religious figure) who is not God. In popular culture, this term has a negative connotation as it is often related to Satanist rituals worshiping evil deities and other beings.
