Epistle to the Hebrews: Who Wrote the Book of Hebrews?

The book was not signed, and so there have been many suggestions over the centuries. Honestly, there is no absolute determinative evidence for any suggested author, even Paul. However, we do not live in an absolute world. God is absolute, and the Word of God in the original is absolute. It seems that most researchers that address this appear to offer just a few suggestions to live with the belief that it is best to say that we do not know. There have been many suggested authors since the first century: Paul, Luke, Barnabas, Silas, Apollos, Priscilla and Aquila, James, Philip, Jude, Clement of Rome have all been offered as suggested authors of the book of Hebrews. So, who really wrote the book of Hebrews? Indeed, the book of Hebrews is packed with the most relevant and beneficial information as well as with serious and weighty exhortation, excellent encouragement, and severe warnings lest we fall away from the faith. The better we become informed with this Bible book, the more we profit from what it has to say.
