The 科普特教会 (Coptic Church) is one of the oldest Christian denominations in the world, originating in Egypt. It traces its roots back to the teachings of Saint Mark, who is believed to have founded the church in the first century AD. The Coptic Church is known for its rich traditions, unique liturgical practices, and its use of the 科普特语 (Coptic language), which is derived from ancient Egyptian. The Coptic Church is part of the larger family of 东方正教会 (Oriental Orthodox Churches) and has its own distinct beliefs and practices. It emphasizes the importance of the sacraments, particularly the Eucharist, and has a strong monastic tradition. The church plays a significant role in the cultural and religious life of Egypt, where it represents a significant minority of the population.
