A.J. Gordon ascribes the authorship of Hebrews to Priscilla, writing that "It is evident that the Holy Spirit made this woman Priscilla a teacher of teachers". Later proposed by Adolf von Harnack in 1900, Harnack's reasoning won the support of prominent Bible scholars of the early twentieth century. Harnack believes the letter was written in Rome – not to the Church, but to the inner circle. In setting forth his evidence for Priscillan authorship, he finds it amazing that the name of the author was blotted out by the earliest tradition. Citing , he says it was written by a person of "high standing and apostolic teacher of equal rank with Timothy". If Luke, Clemens, Barnabas, or Apollos had written it, Harnack believes their names would not have been obliterated.
