For Peter: It seems from posts I've read here in the last year or so that you must no longer agree much with the above conclusion, because it seems you have real doubts about Paul's existence. I assume some arguments disputing Paul's existence have taken on greater weight, but wonder if those alone have weakened your position on the 'we' passages, or if that position has weakened based on direct arguments pertaining to the 'we' passages.Chief among the features of Luke-Acts that have always been thought to support the idea that the author knew Paul are the "we passages" found in 16:10-17, 20:5-15, 21:1-18, and 27:1-28:16. For example, Acts 16:10-17 reads, "We set sail from Troas, making a straight run for Samothrace, and on the next day to Neapolis, and from there to Philippi, a leading city in that district of Macedonia and a Roman colony. We spent some time in that city. ... As we were going to the place of prayer, we met a slave girl with an oracular spirit, who used to bring a large profit to her owners through her fortune-telling. She began to follow Paul and us, shouting, 'These people are slaves of the Most High God, who proclaim to you a way of salvation.'" Paul exorcised her and was imprisoned for his trouble. Paul was saved as an answer to his prayer, and he proceeded to travel through Thessalonica, Beroea, and Athens. Paul set sail for Syria by way of Ephesus, landed in Caesarea, and went to Antioch. After travelling around Galatia and Phrygia, Paul came to Ephesus in Asia Minor where Apollos was baptizing in the name of John. After an upset with the silversmiths in Ephesus, the first person narration picks up again as follows: "When the disturbance was over, Paul had the disciples summoned and, after encouraging them, he bade them farewell and set out on his journey to Macedonia. As he travelled throughout those regions, he provided many words of encouragement for them. Then he arrived in Greece, where he stayed for three months. But when a plot was made against him by the Jews as he was about to set sail for Syria, he decided to return by way of Macedonia. Sopater, the son of Pyrrhus, from Beroea, accompanied him, as did Aristarchus and Secundus from Thessalonica, Gaius from Derbe, Timothy, and Tychicus and Trophimus from Asia who went on ahead and waited for us at Troas. We sailed from Philippi after the feast of Unleavened Bread, and rejoined them five days later in Troas, where we spent a week. On the first day of the week when we gathered to break bread, Paul spoke to them because he was going to leave on the next day, and he kept on speaking until midnight. ... We went ahead to the ship and set sail for Assos where we were to take Paul on board, as he had arranged, since he was going overland. When he met us in Assos, we took him aboard and went on to Mitylene. We sailed away from there on the next day and reached a point of Chios, and a day later we reached Samos, and on the following day we arrived at Miletus. Paul had decided to sail past Ephesus in order not to lose time in the province of Asia, for he was hurrying to be in Jerusalem, if at all possible, for the day of Pentecost." (Acts 20:1-16) Notice that the first passage refers to "Paul and us" and that the "we" who sailed to Assos are distinct from Paul, who travelled overland. Notice also that the "we" narration drops off at Philippi and then picks up in the second passage with "We sailed from Philippi." This nonchalant and matter-of-fact dovetailing convinces me that the author of Acts was among those who were left behind at Philippi and joined up with Paul to sail from there later. The distinction between Paul and "us" discredits the idea that the first person perspective in these passages is some kind of literary device, which would take the perspective of Paul (for example increasing the drama of Paul's adventure or increasing the connection of Paul to the group), and for which there is no precedent in ancient literature. The alternative is that the author of Acts was making a false affectation to being a companion of Paul. This prompts the question of why the author made this claim in such a subtle way, instead of ensuring that the reader could not miss it by emphasizing the point, as apocryphal writers often did. It also leaves us wondering as to why the false claim to participation is restricted to a few passages, leaving Paul alone for most of the narrative--though this is understandable if the author's participation was in fact sporadic. The most probable conclusion is that Luke had travelled with Paul at times, a fact of which Luke's patron Theophilus was already aware.
For anyone else, what are your main objections to the above analysis?
Please avoid reading motivations into my question. I do find the above to be fairly persuasive, but I am wanting to understand the views of those who don't, including perhaps the original author himself.
