Eyewitnesses Of Acts' Events Living Into The Second Century

We're accustomed to framing timing issues in early Christianity around Jesus' life. He died in the 30s, so we think of a document written in the 60s as postdating Jesus' life by about three decades, for example.

But we need to keep in mind that many significant events, like the ones narrated in Acts, occurred after Jesus' life on earth. Acts closes with events in Rome in the 60s. Some people who were in Rome at the time surely lived into the second century, probably multiple decades into the second century in some cases. That diminishes the popular skeptical suggestion that individuals in the second century wouldn't have had firsthand knowledge about issues like the dating and authorship of documents, were just speculating about such issues without much to go by, etc.

I've cited Acts as an example here, and something else that's significant about Acts is its connection to the third gospel. The fact that people with firsthand knowledge of Acts' authorship and the circumstances surrounding it could so easily have lived well into the second century, and that some probably did, adds weight to the universal testimony from the second century onward that the third gospel was written by Luke. (And there are multiple sources who partially or fully corroborate that authorship attribution prior to Irenaeus, as discussed here.)

This distinction between the timing of Jesus' life and the timing of later events is also relevant in many other contexts: the suffering of the apostles, their martyrdom, apostolic miracles, etc. Always ask yourself what timeframe is relevant to the issue under consideration. Be careful not to assume the timeframe of Jesus' life in contexts that involve a different timeframe instead.

Did the earliest information about Christianity circulate entirely in oral form?

A post I wrote last week about Josephus was partly about the likelihood that the earliest Jewish opponents of Christianity communicated about the religion in writing. Elsewhere in Tom Schmidt's book that I cited, he discussed a line of evidence I've brought up before. "For the same reason during the 30s CE it is probable that Saul of Tarsus received letters from none other than a high priestly son of Ananus I instructing him to arrest followers of Jesus." (Josephus And Jesus [New York, New York: Oxford University Press, 2025], 185) In a footnote, Schmidt cites Acts 9:1-2 and 22:5. There are other examples of actual or potential references to Christianity in written sources that are no longer extant, among both non-Christians and Christians. See my post here that discusses the example in Acts mentioned above and others. See, also, my discussion here regarding how the genealogy of Jesus in the gospel of Luke likely came from the brothers of Jesus, most likely James, and probably in written form.

What Justin Martyr said about early Jewish responses to Christianity, which I discussed in my last post, probably involved written material as well, not just oral sources.

People often speak of the earliest history of Christianity as if it involved only oral communication about the religion or as if any written sources that existed at the time had little or no significance. But that doesn't make much sense in the abstract, it's inconsistent with the large amount of documents we have from Christians from the middle of the first century onward, and it's contradicted by the references we have to early written sources that are no longer extant (the likely presence of written documents other than the canonical gospels in the "many" sources of Luke 1:1-3; Acts 9:1-2, 15:23-29; etc.). The nature of life is such that communicating orally makes more sense in some contexts, and communicating in writing makes more sense in other contexts. Both would have been present from the start of Christianity, not just later on. And that start of Christianity includes Jesus' life before his public ministry.

Why trust the early Christians' memories?

Skeptics (of Christianity and skeptics in other contexts) often try to cast doubt on the reliability of human memory. Michael Jones (InspiringPhilosophy) has posted a couple of videos that make some good points about the reliability of the earliest Christians' memories of Jesus and their memories more broadly (here and here). Other points could be made as well. For example, I've written about the many documents relevant to Jesus' life that predated the gospels, meaning that there was more than memories and oral tradition to go by at the time when the gospels were composed. See here regarding early documents related to Jesus' childhood and here on early documents related to his resurrection, for instance. And see here regarding the evidence that the earliest Christians thought the apostles were given the ability to produce scripture, meaning that more than ordinary memory was involved (e.g., John 14:26).
