Ethiopian Orthodox Christianity is one of the oldest Christian traditions in the world, tracing its roots back to the 4th century. It is characterized by its unique practices, including the use of the ancient Ge'ez language in liturgy and a strong emphasis on fasting and prayer. The church venerates a rich array of saints and has a distinct calendar of religious festivals. The Ethiopian Orthodox Church is part of the larger Oriental Orthodox communion and has a significant cultural influence in Ethiopia. It is known for its ancient churches, many carved from rock, and its deep connection to the Ark of the Covenant, which is believed to be housed in Axum.
