Thank you for the question on the authorship of the Book of Hebrews, “Could Apollos have written the book of Hebrews as a scribe to Paul?”
Bible scholars debate the authorship of the Book of Hebrews. There are three likely authors to this book. They are as follows:
- The Apostle Paul
- Barnabas
- Apollos
The author does not identify himself by name in this letter. Scholars have noted the following things about the author:
- The author is very familiar with the Septuagint since the author quotes from it than the Hebrew text.
- The author is a man, not a woman since the pronoun, I, is masculine in Hebrews 11:32.
- The author did not met the Lord but met the witnesses of the Lord who confirm what they heard and saw of the Lord (Heb. 3:3).
- The author is able to write the text in beautiful and stylistic Greek.
- The author is very familiar with the Tabernacle (Heb. 8–10).
- The author is very familiar with the Old Testament history (Heb. 11).
- The author is writing to Jews, not Gentiles (Heb. 3:12)/
- The author is familiar with Timothy being released from prison (Heb. 13:23).
- The author is familiar with believers in Italy.
It is likely that this epistle was written before the Fall of Jerusalem in 70 CE otherwise. Early Church Fathers attributed this epistle to the Apostle Paul while Tertullian attributed it to Barnabas. Martin Luther attributed the authorship to Apollos.
The reason that I do not think that Apollos was a scribe for the Apostle Paul is that he was able to write in Hebrew and in Greek. The exception would be as Paul’s vision diminished, he needed someone to write for him. In the Epistle to the Romans, the scribe is Tertilus (Rom. 16:22). Can Apollos be a scribe of Paul? Yes, but that function doesn’t seem to fit him a scribe of Paul when he was known for his teaching. Apollos as a traveling companion of Paul would have taught more than he wrote. This doesn’t discount his ability to write to the Hebrew Jews, but it appears he was more of an orator, teacher than a scribe.
In my opinion, it is more likely Barnabas wrote Hebrews than Apollos who may have been a scribe for the Apostle Paul. As a Levite, he was familiar with the Temple worship, recognized as one of the church leaders and mentor for Saul who later became Paul.
SUMMARY: The author is unknown and it is more likely to be Barnabas than Apollos due to Barnabas standing within the Jewish community.
