The book has been widely accepted by the Christian church as inspired by God and thus authoritative, despite the acknowledgment of uncertainties about who its human author was. Regarding authorship, although the Epistle to the Hebrews does not internally claim to have been written by the Apostle Paul, some similarities in wordings to some of the Pauline Epistles have been noted and inferred. In antiquity, some began to ascribe it to Paul in an attempt to provide the anonymous work an explicit apostolic pedigree.
