Christian Orthodoxy refers to the branch of Christianity that follows the teachings and traditions established by the early Church, particularly the decisions made at the seven ecumenical councils. It emphasizes the importance of maintaining the original beliefs and practices of the faith, which include the veneration of saints, the significance of the sacraments, and the authority of the Bible. The Orthodox Church is made up of various national churches, such as the Greek Orthodox Church and the Russian Orthodox Church, each with its own cultural expressions but united in core beliefs. Worship in Orthodoxy is characterized by rich liturgical traditions, including the use of icons and chanting, which help to create a deep spiritual experience for the faithful.
