A relatively small group that has broken away from an established church is a sect.
Usually an offshoot of a larger group, a sect is a subgroup of a religious, political, or philosophical belief system. The phrase once applied to religiously distinct groups, but it is now used to describe any group that separates from a larger one in order to adhere to a different set of rules and values. The perception of heresy by the subgroup and/or the wider group typically leads to the formation of sects.
The Latin noun secta, which means "a path, road" and is the feminine form of the verb sequin's alternate past participle, is where the word sect first appeared. In a figurative sense, a sect is a way, mode, or manner. By way of a collection of practices' and doctrines, a sect is a discipline or school of thought.
