Definition of heretical

The word "heretical" has its roots in the Latin language. It originates from the term "haereticus," meaning "sectarian" or "heretic." This Latin term was derived from the Greek word "hairetikos," meaning "sectarian" or "separatist." The Greek word "hairetikos" is composed of two words, "haireo," meaning "to choose," and "tikos," meaning "follower." In the early Christian Church, the term "haereticus" was used to describe those who rejected the Orthodox Christian creed and believed in false teachings. Over time, the term evolved into the English word "heretical," which refers to any opinion or doctrine that is considered unacceptable or contrary to established norms. Today, the term is often used to describe religious or ideological beliefs that are considered unconventional or oppositional.
