" there remains nothing to hinder the belief that the   devout Levite of Cyprus, the early convert to Christianity while still   in strong sympathy with the Christian Jews, the man of benevolence and   wealth, and therefore probably of education, by birth the appointed   servant of the temple, the man of independence and dignity, and yet of   such tender sympathy as to be surnamed "Son of consolation," the long   and intimate companion of St. Paul, and for years in the position of   his superior,--there is nothing to hinder the acceptance of the early   ecclesiastical statement that he was also the author of the Epistle to   the Hebrews.    Frederic Gardiner.     "
