The apologetic explanation that a first-century CE human Jesus came to fulfill the scriptures requires faith --- that is, belief in the supernatural such that the prophets and other authors of the Hebrew scriptures were inspired by a divine being so they could foretell the future.
The other option does not require the supernatural. The earliest believers in the Christ, employing allegorical midrash, found previously hidden meanings in the scriptures leading them to believe that their Christ had suffered, died, and was resurrected sometime in the distant past (or in a heavenly realm). The later writers of the NT Gospels used the scriptures to construct their elaborate tales, including the passion.
Paul’s Christ was “staked”. He also described the event as “hanging on a tree/ beam of wood/ wood stocks”, Greek xylou (ξύλου),
Paul tells the reader that “it has been written” about this hanging, clearly a reference to the Jewish scriptures (Galatians 3:10). The scriptural source of Paul’s reference here may have been an allegorical interpretation of Deuteronomy 21:22-23. Other options have been suggested.“Christ redeemed us from the curse of the law, having become a curse for us. For it has been written --- cursed (is) everyone hanging on a tree [or beam or stocks]; that the blessing of Abraham might come on the Gentiles in Jesus Christ; that we might receive the promise of the spirit through faith.” (Galatians 3:13-14).
Certainly it would have been difficult for Paul, using a pile of scrolls, to show the Galatians and his other congregations the many widely scattered passages in the Jewish scriptures that demonstrated the events of his Christ. In a passage that may reveal some useful information in the mostly fictional Acts, it took Paul 3 days to provide a demonstration of his Christ from the Jewish scriptures. (Acts 17:1-3).
The difficulty of such a method of transmission could certainly have limited the early spread of belief in the Christ, and could have been an impetus for Mark to write his tale --- to make the Christ more accessible to all.
It was Mark that came up with the concept of a Roman execution. As Burton Mack describes,
Perhaps there are non-extant Greek translations of Hebrew scriptures that were used by some early believers in the Christ and some NT authors. Most NT writers apparently used the Septuagint, but some NT references better reflect the extant Masoretic text. One example is the use of Zechariah 12:10,"Mark took the basic ideas from the Christ myth but dared to imagine how the crucifixion and resurrection of the Christ might look if played out as a historical event in Jerusalem …" (Mack, 1995, p. 152).
The author of the Gospel of John clearly applies this reference in Zechariah to Jesus,"And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and supplication. They will look on me, the one they have pierced, and they will mourn for him as one mourns for an only child, and grieve bitterly for him as one grieves for a firstborn son." (Zechariah 12:10 --- NIV).
Justin Martyr interpreted Zechariah 12:10 in a similar fashion from his second-century Christian perspective, (First Apology, 52)."And again another scripture says, they will look on him whom they pierced." (John 19:37).
Earl Doherty characterizes the situation,
Philo of Alexandria (ca. 20 BCE to 50 CE), in his On the Contemplative Life, described a community of Jewish sectarians called the Therapeutae. They had separate rooms in their dwellings used only for study of the Jewish scriptures. The Therapeutae spent many hours of the day searching the scriptures for, as Philo put it, "… literal expressions as symbols revealing secret and hidden meanings …"“Scripture did not contain any full-blown crucified Messiah, but it did contain all the required ingredients. Jewish midrash was the process by which the Christian recipe was put together and baked into the doctrine ….” (Doherty, 2009, p. 87).
I’m not suggesting that the earliest believers in the Christ were Philo’s Therapeutae. But Philo’s report clearly demonstrates that Jewish sectarians of the period were actively searching for new meanings in their sacred scrolls --- new meanings to give them hope in troubled times.
