One such attempt to create doubt is to bring to the forefront the disagreement with the placement of the book of Hebrews, reiterating that no one really knows who wrote this particular book. That is, should it be included in the Pauline epistles with Paul as the author or left in the category, general epistles, with the mystery of who wrote it forever dangling just out of reach. The author of Hebrews was unknown even to the early church fathers: Tertullian implies Barnabas wrote the manuscript. Regardless of who wrote this inspiring message to the Hebrews is of small matter, for the value lies within the lesson itself. That the headings of each book were chosen to help the reader find a designated letter has no bearing on the accuracy of the text; the headings were not placed on the original manuscripts and, thus, there is no end to debates on authorship.
