Christian orthodoxy refers to the accepted beliefs and doctrines of the Christian faith that have been established over centuries. It encompasses core tenets such as the belief in the Trinity, the divinity of Jesus Christ, and the authority of the Bible. These beliefs are upheld by various Christian denominations, particularly within Catholicism and Eastern Orthodoxy. The term also signifies adherence to traditional interpretations of scripture and teachings, distinguishing orthodox beliefs from heretical views. Throughout history, councils such as the Council of Nicaea have played a crucial role in defining and affirming these orthodox beliefs, shaping the foundation of mainstream Christianity.
