Most Christians are unaware that the Bible has more than one priesthood. They are familiar with the well-known priesthood of the Old Testament, and if they are exceptionally savvy, they know it to be called the Levitical Priesthood. Still, most lay Christians often forget the second priesthood.
Because the author of Hebrews is unknown, it can only be said that the Epistle is the work of "one of the [greatest] theologians of the New Testament." While it is unclear to whom this title belongs, there have been many assumed authors, such as the Apostle Paul. However, Pauline authorship is not accepted by many scholars today. Other candidates for the authorship of Hebrews include "Clement of Rome, Barnabas, Apollos, Luke, Silas, Priscilla, Philip, and even Mary the mother of Jesus." The obvious problem with these assumptions is that there are no known texts written by any of these supposed authors apart from Luke, and Lukan authorship is mostly refuted due to linguistic and rhetorical differences.
