There was simply nowhere near enough time for mythology to thoroughly corrupt the historical record of Jesus, especially in the midst of eyewitnesses who still had personal knowledge of him. When German theologian Julius Műller in 1944 challenged anyone to find a single example of legend developing that fast anywhere in history, the response from the scholars of his day—and to the present time—was resounding silence.(8)
Historically speaking, the news of his empty tomb, the eyewitness accounts of his post-Resurrection appearances, and the conviction that he was indeed God’s unique Son emerged virtually instantaneously. A good case can be made for saying that Christian belief in the Resurrection, though not yet written down, can be dated to within two years of that very event !!
In Paul’s epistles, he incorporated some creeds, confessions of faith, or hymns from the earliest Christian church. The most famous creeds include Philippians 2:6-11 and Colossians 1:15-20. But perhaps the most important in terms of the historical Jesus is 1 Corinthians 15, where Paul uses technical language to indicate he was passing along this oral tradition in relatively fixed form.
If the Crucifixion was as early as AD 30, Paul’s conversion was then about A.D. 32. Immediately Paul was ushered into Damascus, where he met with a Christian named Ananias and some other disciples. His first meeting with the apostles in Jerusalem would have been about AD 35. At some point during those few years Paul was given this creed, which had already been formulated and was being used in the early church.
In 1 Corinthians 15 this creed spells out the key facts about Jesus' death for our sins, plus a list of those he appeared to in resurrected form:
"...Peter, and then to the Twelve. After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living..." (1 Cor 15:5-6 NIV)
Though not written down yet, this all can be dated back to within 2-5 years of the events themselves !!
In the first few chapters of the Book of Acts, Luke apparently preserved material from very early sources. Scholars have discovered that the language used in these early speeches about Jesus is quite different from that used at the time when the book was compiled in its final form. (9) This evidence certainly points back to a time immediately after the resurrection event.
The nature of Christian thought before the writing of the New Testament consisted of these early Christian creeds which were later written in the books of the New Testament. These creeds were communicated verbally years before they were written and hence they preserve some of the earliest reports concerning Jesus. Therefore, in a real sense, the creeds preserve pre-New Testament material, and are our earliest sources for the life of Jesus.
These creeds, and later the written gospels attesting to Jesus’ teachings, miracles, and resurrection, were circulated very shortly after the crucifixion and within the lifetimes of Jesus’ contemporaries and critics. As stated, the 1 Corinthians 15 creed, affirming Jesus’ death for our sins and listing his post-Resurrection appearances to named eyewitnesses, was already being recited by Christians as soon as twenty-four months after the Crucifixion.
Critics certainly would have set the record straight at the time if there had been embellishment or falsehood. Had there been witnesses at the time saying “I was there and that never happened,“ then surely Christianity would never have taken hold and exploded as it did.
