The anonymous author of Luke–Acts lacked exact analogies in Hellenistic or Jewish literature. He anchored his history by dating the birth of the founder Jesus, and told how the founder was born from God, taught authoritatively, and appeared to witnesses after his death before ascending to heaven. The sources for Acts can only be guessed at, but the author would have had access to the Septuagint Greek Bible, the Gospel of Mark, and either the hypothetical collection of “sayings of Jesus” called the Q source or the Gospel of Matthew. He transposed a few incidents from Mark’s gospel to the time of the apostles. The Christian Antioch community may have provided information about the growing Hellenistic Christian community. The traditional explanation of the three “we” sections is that they represent eyewitness accounts.
