The Coptic Orthodox Church of
Egypt
was founded in the name of
Jesus
in the first century and still bears witness to the name of its Lord .
It is named the "Coptic Church" , according to its nationality and "Orthodox" according to its creed . The name "Orthodox" is a compound word - Ortho Doxa - which means "Original Faith" . This title was given to the Coptic Church , because it defended the old creed against several attacks , which were made upon it during succeeding centuries . The Christians of Egypt , Sudan and Ethiopia now follow the creed of the Coptic Church .
