Author and Date
The earliest suggestion of authorship is found in Tertullian's De Pudicitia, 20 (c. 200), in which he quotes from "an epistle to the Hebrews under the name of Barnabas." From the letter itself it is clear that the writer must have had authority in the apostolic church and was an intellectual Hebrew Christian well versed in the OT. Barnabas meets these requirements. He was a Jew of the priestly tribe of Levi () who became a close friend of Paul after the latter's conversion. Under the guidance of the Holy Spirit, the church at Antioch commissioned Barnabas and Paul for the work of evangelism and sent them off on the first missionary journey ().
The other leading candidate for authorship is Apollos, whose name was first suggested by Martin Luther and who is favored by many interpreters today. Apollos, an Alexandrian by birth, was also a Jewish Christian with notable intellectual and oratorical abilities. Luke tells us that "he was a learned man, with a thorough knowledge of the Scriptures" (). We also know that Apollos was associated with Paul in the early years of the church in Corinth (; ).
One thing is evident: The author was a master of the Greek language of his day, and he was thoroughly acquainted with the pre-Christian Greek translation of the OT (the Septuagint), which he regularly quotes.
Hebrews must have been written before the destruction of Jerusalem and the temple in a.d. 70 because:
Recipients and Theme
The theme of Hebrews is the absolute supremacy and sufficiency of Jesus Christ as revealer and as mediator of God's grace. The prologue () presents Christ as God's full and final revelation, far surpassing the revelation given in the OT. The prophecies and promises of the OT are fulfilled in the "new covenant" (or "new testament"), of which Christ is the mediator. From the OT itself, Christ is shown to be superior to the ancient prophets, to angels, to Moses (the mediator of the former covenant) and to Aaron and the priestly succession descended from him. Hebrews could be called "the book of better things" since the two Greek words for "better" and "superior" occur 15 times in the letter. A striking feature of this presentation of the gospel is the unique manner in which the author employs expositions of eight specific passages of the OT Scriptures:
Practical applications of this theme are given throughout the book. The readers are told that there can be no turning back to or continuation in the old Jewish system, which has been superseded by the unique priesthood of Christ. God's people must now look only to him, whose atoning death, resurrection and ascension have opened the way into the true, heavenly sanctuary of God's presence. To "ignore such a great salvation" () or to give up the pursuit of holiness ) is to face the anger of the "living God" (). Five times the author weaves into his presentation of the gospel stern warnings (see on ) and reminds his readers of the divine judgment that came on the rebellious generation of Israelites in the desert.
