The series Biblia Coptica for the first time presents a systematic compilation of all biblical texts of the Old and New Testament from the area of the ancient Coptic Church of Egypt: the Sahidic Old and New Testament. Karlheinz Schüssler succeeded in largely reconstructing the original structure and amount of different codices, being able to collate numerous manuscript sheets to the original manuscript, sheets that in former times had been torn from the codices and today are kept in widely scattered museums and libraries. Each text contains detailed information including its depository. Each single part of the compilation contains a register of bible passages, a section of plates, and the fourth part of each volume includes a comprehensive overall register.
The complete collection of the Sahidic Old and New Testament is of fundamental importance for both Biblical theology/exegesis/textual criticism and church and canonical history.
