"이단자들" refers to individuals or groups that hold beliefs or practices that deviate from the established doctrines of a particular religion. In many cases, these beliefs are considered heretical by mainstream religious authorities. The term is often used in the context of Christianity, where certain sects or movements may be labeled as heretical due to their differing interpretations of scripture. In various cultures, being labeled as "이단자들" can lead to social ostracism or persecution. This term is significant in discussions about religious freedom and the boundaries of acceptable belief systems. It highlights the tension between orthodoxy and alternative interpretations within faith communities, such as Christianity and Islam.
