According to Clement of Alexandria, Paul wrote the Epistle to the Hebrews in the Hebrew language.  Luke, who traveled with Paul on his missionary journeys, translated it into Greek – thus explaining the writing style similar to that of Acts and the Gospel of Luke.  Eusebius writes, “Clement says that, writing to the Hebrews (who were prejudiced against Paul and suspicious), he with great wisdom did not repel them in the beginning by putting down his name. . . . And now, as the blessed presbyter [Clement] used to say, the Lord, as the Apostle of the Almighty, was sent to the Hebrews.  However, Paul was sent to the Gentiles.  Therefore, Paul did not subscribe himself as apostle to the Hebrews, out of modesty and reverence for the Lord.”  Origen also believed that Paul wrote the book of Hebrews, although Tertullian ascribed it to Barnabas.
