Why was the church called orthodox?

The term "orthodox" comes from the Greek Words "orthos," meaning "correct," and "doxa," meaning "belief" or "opinion." The church was called orthodox to signify its adherence to what was considered the correct or true beliefs of Christianity, particularly in contrast to heretical movements. It emphasizes the importance of maintaining traditional doctrines and practices that align with the teachings established by the early Church Fathers and ecumenical councils. This designation helped to unify believers under a common set of theological principles.
