The Coptic Church was established in the name of the Lord Jesus Christ by St. Mark the Evangelist in the city of Alexandria around 43 A.D. The church adheres to the Nicene Creed. St. Athanasius (296-373 A.D.), the twentieth Pope of the Coptic Church effectively defended the Doctrine of the Lord Jesus Christ's Divinity at the Council of Nicea in 325 A.D. His affirmation of the doctrine earned him the title; "Father of Orthodoxy" and St. Athanasius "the Apostolic".
The term "Coptic" is derived from the Greek "Aigyptos" meaning "Egyptian". When the Arabs arrived in Egypt in the seventh century, they called the Egyptians "qibt". Thus the Arabic word "qibt" came to mean both "Egyptians" and "Christians".
The term "Orthodoxy" here refers to the preservation of the "Original Faith" by the Copts who, throughout the ages, defended the Old Creed against the numerous attacks aimed at it.
