The Coptic Church
"...On one hand, its theology is based on nothing outside the scriptures. On the other hand, the doctrines agree in all parts with those of the Early Church i.e. the tradition which has the proper interpretation and application of the teachings of our Lord and the Apostles as understood and practiced by the Christians and the leaders of the Church during the period of the One Universal Church until the division of 451 A.D."
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.
The Coptic Orthodox Church worships the Father, the Son and the Holy Spirit in the Oneness of Nature. We believe in One God; Father, Son and Holy Spirit three equal Co-Essential and Co-Indwelling Hypostasis (Persons). The Blessed and Holy Trinity is our One God. We Believe that Lord Jesus Christ, the Only-Begotten of the Father and Who is One with Him in Essence is the only Savior of the world; we are Miaphysites; There is a difference between the Monophysites who believe in just One Single Nature (Divine) of Lord Jesus Christ and the Miaphysites who believe in One United Nature or One Composite Nature (Divine & Human) of Lord Jesus Christ. We do not believe in just a Single Nature but we do believe in the One Incarnate Nature of the Logos. Less changes have taken place in the Coptic Church than in any other church whether in the ritual or doctrine aspects and that the succession of the Coptic Patriarchs, Bishops, priests and Deacons has been continuous.
