Православ'я, or Orthodoxy, is one of the major branches of Christianity. It emphasizes the importance of tradition, the sacraments, and the teachings of the early Church. The Orthodox Church is known for its rich liturgical life, including the Divine Liturgy, which is central to its worship practices. The Orthodox faith is characterized by its adherence to the seven ecumenical councils and the belief in the Holy Trinity. It is organized into various national churches, such as the Russian Orthodox Church and the Greek Orthodox Church, each maintaining its own customs while sharing core beliefs.
