Sounds like this Mr Wells should . . . crack open the Acts of the Apostles.
Mr. Wells has much to say regarding Acts and the historical record and Jesus. I’m afraid his findings will not meet to your satisfaction:
"Acts does not carry the history of the church up to the author’s own time, but depicts only Christianity’s path from Jerusalem to Rome – the ‘heroic’ period when the church was (supposedly) free from heresy, and when its officials still behaved impeccably, leading an ideal and completely harmonious community, widely respected and secure with its miraculous deeds. This was not conscious idealization, but was how the author and Christians generally of the early second century will have viewed the original period.
One of Acts’ overall concerns is to make clear that Christianity posed no threat to the authority of the Romans. Hence, although the author could not – against the obvious truth – conclude the book by having Paul set free from Roman captivity, he does his best to insinuate that this is what the Romans wanted. At 28:17-19 he goes so far as to make Paul say as much (‘the Romans, who, when they had examined me, desired to set me at liberty’) and to make him claim that he had to appeal to stand trial in Caesar’s court in Rome only in order to protect himself from hostile Jews in Judea. In his invaluable commentary on Acts – its seventh and final edition appeared in 1977, two years after the author’s death – Ernst Haenchen observes that even the account in earlier chapters of the book of Acts itself fails to bear this out; for only those Romans who do not have authority to decide Paul’s case are there represented as favouring his acquittal. Thus Claudius Lysias found him innocent (23:29), but, as a subordinate official, was obliged to send him to the governor Felix for trial. Later, Felix’ successor Festus declared him innocent (25:18. 25 and 26:31 1) only after the appeal to Rome had taken the case out of his hands. It is, then, clear what the author of Acts wants us to believe, and equally clear that he was not able to make the evidence add up to it. Moreover, Paul’s arrest and the proceedings against him are, for Acts, no minor matter, but occupy the whole of the final quarter of the book (chapters 21 to 28)."
(Paul) didn’t need to constantly teach in the format “Christ said …” because as an Apostle, Christ gave HIM authority to teach.
This claim doesn’t help in proofing that Jesus did infact exist either.
“If the gospels do not help us, we fare no better with the equally late Acts of the Apostles. In his first speech there Peter claims that he and others had kept Jesus’ company from his baptism onwards. But in no extant document before the gospels is Peter or anyone else called a ‘disciple’ in the sense of a companion during a ministry. The term used in the earliest documents is ‘apostle’ and it there means missionary’. After Acts 16:4 there is no further mention of these alleged companions of Jesus. They disappear from the narrative, with no suggestion that they appointed successors. The missionary work in the Diaspora is represented as effected principally by Paul.”
