Most evangelical Christians today maintain that the anonymous Letter to the Hebrews could not have been written by the apostle Paul. For example, the monumental Dictionary of Paul and His Letters (published 1993 by Inter-Varsity Press Academic, edited by Gerald F. Hawthorne, Ralph P. Martin and Daniel G. Reid) does not include the Letter to the Hebrews among those written by Paul. Some commentaries and books on the New Testament suggest that Apollos or Barnabas, instead, could have written this letter. Others also suggest Priscilla.
One Bible commentary has even judged that, because of the lack of a clear identity of the author of this letter, it would be presumptuous for anyone to suggest any possible author.
