Did Paul Write Hebrews?
“As early as the end of the second century the church of Alexandria in Egypt accepted Hebrews as a letter of Paul, and that became the commonly held view in the East. Pauline authorship was contested in the West in the fourth century, but then accepted. In the sixteenth century, doubts about that position were again raised, and the modern consensus is that the letter was not written by Paul. There is, however, no widespread agreement on any of the other suggested authors, e. g., Barnabus, Apollos, or Priscilla and Aquila. The document itself has no statement about its author”—Introduction to The Letter To The Hebrews, New American Bible (NAB)
