ortodoksisiin

Ortodoksisuus refers to the Eastern Orthodox Church, a major branch of Christianity that traces its origins back to the early church established by Jesus Christ and his apostles. The word itself, derived from Greek, means "correct belief" or "correct worship." Orthodox Christianity is characterized by its adherence to ancient traditions, its liturgical practices, and its emphasis on the teachings of the ecumenical councils.

The Eastern Orthodox Church is a communion of self-governing churches, each led by a patriarch or archbishop. Key theological tenets include the divinity of Jesus Christ, the Holy Trinity, and the veneration of icons, which are considered windows to the divine. The Divine Liturgy, a rich and symbolic worship service, is central to Orthodox spiritual life.

Historically, the Great Schism of 1054 formally separated the Eastern Orthodox Church from the Roman Catholic Church. While sharing many common roots, theological and jurisdictional differences led to the permanent division. Orthodox Christianity is prevalent in Eastern Europe, the Middle East, and parts of Africa, with significant communities also found worldwide due to migration. Its theology, spirituality, and canon law have remained largely consistent throughout its history, emphasizing continuity with the early Christian faith.
