fully and authoritatively canonical. They regard themselves as the true "guardians of the Law." This assertion is only re-enforced by the claim of the Samaritan community in Nablus (an area traditionally associated with the ancient city of Shechem) to possess the oldest existing copy of the Torah—one that they believe to have been penned by Abisha, a grandson of Aaron. Christian canons With the potential exception of the Septuagint, the apostles did not leave a defined set of scriptures; instead the canon of both the Old Testament and the New Testament developed over time. Different denominations recognize different lists of books as canonical, following various church councils and the decisions of leaders of various churches. For mainstream Pauline Christianity (growing from proto-orthodox Christianity in pre-Nicene times) which books constituted the Christian biblical canons of both the Old and New Testament was generally established by the 5th century, despite some scholarly disagreements, for the ancient undivided Church (the Catholic and Eastern Orthodox traditions, before the East–West Schism). The Catholic canon was set at the Council of Rome (382). In the wake of the Protestant Reformation, the Council of Trent (1546) affirmed the Vulgate as the official Catholic Bible in order to address changes Martin Luther made in his recently completed German translation which was based on the Hebrew language Tanakh in addition to the original Greek of the component texts. The canons of the Church of England and English Presbyterians were decided definitively by the Thirty-Nine Articles (1563) and the Westminster Confession of Faith (1647), respectively. The Synod of Jerusalem (1672) established additional canons that are widely accepted throughout the Eastern Orthodox Church. Various forms of Jewish Christianity persisted until around the fifth century, and canonicalized very different sets of books, including Jewish–Christian gospels which have been lost to history. These and many other works are classified as New Testament apocrypha by Pauline denominations. The Old and New Testament canons did not develop independently of each other and most primary sources for the canon specify both Old and New Testament books. For the biblical scripture for both Testaments, canonically accepted in major traditions of Christendom, see biblical canon § canons of various traditions. Early Church Earliest Christian communities The Early Church used the Old Testament, namely the Septuagint (LXX) among Greek speakers, with a canon perhaps as found in the Bryennios List or Melito's canon. The Apostles did not otherwise leave
