The Pauline epistles, Epistles of Paul, or Letters of Paul, are the 13 New Testament books which have the name Paul (Παῦλος) as the first word, hence claiming authorship by Paul the Apostle. Among these letters are some of the earliest extant Christian documents. They provide an insight into the beliefs and controversies of early Christianity and as part of the canon of the New Testament they are foundational texts for both Christian theology and ethics. The Epistle to the Hebrews, although it does not bear his name, was traditionally considered Pauline for a thousand years, but from the 16th century onwards opinion steadily moved against Pauline authorship and few scholars now ascribe it to Paul, mostly because it doesn't read like any of his other epistles in style and content. Most scholars agree that Paul really wrote seven of the Pauline epistles, but that four of the epistles in Paul's name are pseudepigraphic; scholars are divided on the authenticity of two of the epistles.
