Ethiopian canons The New Testament of the Coptic Bible, adopted by the Egyptian Church, includes the two Epistles of Clement. The canon of the Tewahedo Churches is somewhat looser than for other traditional Christian groups, and the order, naming, and chapter/verse division of some of the books is also slightly different. The Ethiopian "narrow" canon includes 81 books altogether: The 27 book New Testament; those Old Testament books found in the Septuagint and accepted by the Orthodox; as well as Enoch, Jubilees, 2 Esdras, Rest of the Words of Baruch and 3 books of Meqabyan (these three Ethiopian books of Maccabees are entirely different in content from the four Books of Maccabees known elsewhere). The "broader" Ethiopian New Testament canon includes four books of "Sinodos" (church practices), two "Books of Covenant", "Ethiopic Clement", and "Ethiopic Didascalia" (Apostolic Church-Ordinances). However, these books have never been printed or widely studied. This "broader" canon is also sometimes said to include, with the Old Testament, an eight-part history of the Jews based on the writings of Flavius Josephus, and known as "Pseudo-Josephus" or "Joseph ben Gurion" (Yosēf walda Koryon). Protestant developments (from c. 1517) The Encyclopedia of Theology says that the 27 books which make up the New Testament canon of Scripture are not based on a Scriptural list that authenticates them to be inspired, thus their legitimacy is considered impossible to be distinguished with certainty without appealing to another infallible source, such as the Magisterium of the Catholic Church which first assembled and authenticated this list at the Council of Rome. Catholicism considers the Magisterium, i.e. the teaching authority, has equal position and linked together with Sacred Tradition and Sacred Scripture, each acts in its own way for the goodness of the Church. Rejecting these, Protestant reformers focused on the doctrine of sola scriptura, i.e. the supreme authority of Scripture alone. Sola scriptura is one of the five solas, considered by some Protestant groups to be the theological pillars of the Protestant Reformation. Martin Luther Martin Luther was troubled by four books, referred to as Luther's Antilegomena: Jude, James, Hebrews, and Revelation; while he placed them in a secondary position relative to the rest, he did not exclude them. He did propose removing them from the canon, echoing the consensus of several Catholics such as Cardinal Cajetan and Erasmus, and partially because they were perceived to go against certain Protestant doctrines such as
