Okay, so you know how some people like to go to different places to worship depending on how they see and interpret their religion? Well, it turns out that sociologists have studied these different types of religious movements and have come up with some ways to classify them.
First, there are what we call "traditional religions." These are the ones that have been around for a really long time and have a well-established set of beliefs and practices. Examples of traditional religions include Christianity, Islam, and Judaism.
Then there are "sects." These are like offshoots of traditional religions that have broken away because they have different beliefs or practices. They're usually led by a charismatic figure who has a strong following of people who believe in their message. Examples of sects include the Amish and the Branch Davidians.
Another type of religious movement is a "cult." Now, this is a term that can have negative connotations, but it simply refers to a group that has a very distinct set of beliefs and practices that are often far different from what mainstream society sees as normal. People in a cult typically follow a charismatic leader and have a deep devotion to their beliefs. Examples of cults include the Peoples Temple and the Unification Church.
Finally, there are "New Age" or "spiritual" movements. These are often seen as the most modern of all the different religious movements, and they are characterized by their focus on individual spirituality and self-development. Examples of New Age movements include the Church of Scientology and the New Thought movement.
So, basically, sociologists have studied the different ways that people practice their religions, and have come up with these different classifications to help us understand how they differ from each other.
