The Book of Hebrews was written by an unknown author.
The fourteenth of the Epistles, and the nineteenth book in the New Testament, is entitled Hebrews. It was written in approximately 68 AD, but by whom, we do not know. Several possible authors have been credited with the work, but the style of writing is unlike any other books in the Bible, and so the author remains unknown.
The letter is addressed to Jewish Christians, many of whom found themselves persecuted by their fellow Jews. The writer of Hebrews fears that Jewish Christians are in danger of slipping back into the Jewish faith because of this persecution. To affirm them in their new found Christian faith, the author shows them Christ's superiority over all Old Testament laws and practices. He urges the Christians to remain true to the Gospel of Jesus Christ, their saviour.
Hebrews 4:14-15
"Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin"
