does seem clear that it was not given by the author, as the word práxeis (deeds, acts) only appears once in the text (Acts 19:18) and there it does not refer to the apostles but refers to deeds confessed by followers to the apostles. The Gospel of Luke and Acts make up a two-volume work which scholars call Luke–Acts. Together they account for 27.5% of the New Testament, the largest contribution attributed to a single author, providing the framework for both the Church's liturgical calendar and the historical outline into which later generations have fitted their idea of the story of Jesus and the early church. The author is not named in either volume. According to Church tradition dating from the 2nd century, the author was the "Luke" named as a companion of the apostle Paul in three of the letters attributed to Paul himself; this view is still sometimes advanced, but "a critical consensus emphasizes the countless contradictions between the account in Acts and the authentic Pauline letters." (An example can be seen by comparing Acts's accounts of Paul's conversion (Acts 9:1–31, 22:6–21, and 26:9–23) with Paul's own statement that he remained unknown to Christians in Judea after that event (Galatians 1:17–24).) The author "is an admirer of Paul, but does not share Paul's own view of himself as an apostle; his own theology is considerably different from Paul's on key points and does not represent Paul's own views accurately." He was educated, a man of means, probably urban, and someone who respected manual work, although not a worker himself; this is significant, because more high-brow writers of the time looked down on the artisans and small business people who made up the early church of Paul and were presumably Luke's audience. The earliest possible date for Luke-Acts is around 62 AD, the time of Paul's imprisonment in Rome, but most scholars date the work to 80–90 AD on the grounds that it uses Mark as a source, looks back on the destruction of Jerusalem, and does not show any awareness of the letters of Paul (which began circulating late in the first century); if it does show awareness of the Pauline epistles, and also of the work of the Jewish historian Josephus, as some believe, then a date in the early 2nd century is possible. The majority scholarly position is that the Lucan author did not know Josephus,
