If Paul could speak to us from the grave, he might borrow a line, further misquoting Mark Twain, "The rumors of my travels are greatly exaggerated."
If one appropriately ignores the fictional accounts in Acts, and derives Paul's travel itinerary from the only primary evidence available --- those authentic letters in which his travels are mentioned (1 Thessalonians, 1 and 2 Corinthians, Galatians, and Philippians) --- an entirely different story emerges.
After leaving Judea/Syria, Paul made a journey into the heart of Galatia proper, and made one counter-clock-wise circuit, landing around the fringe of the Aegean Sea. That's it --- unless one accepts the truth of his story of a return trip to Jerusalem (further discussed below). Beyond Paul's own travels, his subordinates, his co-workers, delivered his letters. There is no reason to believe that delegations from his congregations traveled on Paul's nickel --- those from Corinth to Ephesus could have very well had other business in Ephesus.
But what about Rome? Beyond the fictional Acts, only the letter to the Romans provides evidence for an interest in Rome. But tellingly, the "who are in Rome" is missing from verses 1:7 and 1:15 in some important manuscripts, as well as in the commentary of Origen.
The travel plans in 15:14-33 could point to Rome, but both chapters 15 and 16 are missing from some important manuscripts. Tertullian (Adv Marc) quotes nothing from chapters 15 or 16, even though they contain rich anti-Marcionite material, but he cites 14:10 and says that it comes in the concluding section of the letter. An ending at 14:23 finds support from other sources and analyses as well. It seems likely the letter now called Romans started out as an earlier letter (or treatise) that ended at 14:23, likely followed with an appropriate closing, and lacked any association with Rome. A discussion of these manuscript variants and stylometric problems can be found in many commentaries on Romans for those interested.
And how about Paul's second trip to Jerusalem found in Galatians 2:1-10? I admit, this is the most speculative of my claims about Paul's travels here --- and a claim that finds scant support (if even that) from the literature. None-the-less, I don't believe Paul made that trip, but it's clear to me why he would make up the story. The letter to the Galatians is primarily Paul's defense against some who were promoting certain Jewish practices, especially circumcision, for his congregation. He makes his arguments in chapter 3 and beyond, but he uses chapter 2 to claim support of others for his position. And what better source of approval for his position could Paul use? Who could question the authority of the earliest believers in the Christ spirit, and the figures of sect leadership --- in Jerusalem, the touchstone of Jewish authority?
Notice how Paul prefaces his story of the trip by claiming he was unknown to the Judean assemblies of the Christ (1:22) --- should any of his congregation perchance have opportunity to ask about him. And the events in this second Jerusalem visit were all in private (2:2) and in secret (2:4). Notice that the only named witnesses to the events were Paul's own crew, and the 3 pillars. I think Paul could have been reasonably confident that his Galatian congregation would not have the opportunity to ask any of these sect founders in far off Jerusalem. Why not give it a shot? The congregation was slipping away. Desperate times called for desperate measures.
Even if one takes Paul at his word on this trip to Jerusalem, the expense would have been entirely reasonable in the context of a multi-year career.
Many investigators see more than one visit by Paul to the congregation at Corinth. I believe Paul visited the group only one time, on his initial evangelization. The passage that seems to create the most confusion is 2 Corinthians 13:1-2. Some of the difficulty, in too many bibles, is due to poor translation.
Paul's statement (my translation and emphasis) --- "This third time I AM coming to you" (2 Cor 13:1) --- means that this is the third time that Paul was PLANNING to make another visit. This may seem like special pleading, but a careful analyses of the correspondence supports this interpretation, as does Trobisch (1994, p. 66-67).
Dr. David Trobisch, formerly of the University of Heidelberg, has studied the letters of Paul extensively. I don't agree with all of Trobisch's conclusions in his excellent book, but I do here. Trobisch, in "Paul's Letter Collection --- Tracing the Origins", 1994, writes on page 67 ----
"… his expression in 2 Cor 13:2 'as if I were with you a second time although I am absent now' is to be understood as a definite statement that he has been to Corinth only once."
The received letter 2 Corinthians is a composite of more than one letter, with portions assembled out of chronological sequence. The last we hear from Paul is after his return to Macedonia, when he writes to Corinth to defend his authority in the face of competition from missionaries the congregation liked better (the "super apostles"). We are left with an embattled and downtrodden Paul --- some of his Galatians were turning to the Jewish Mosaic laws, he had been thrown in prison in Ephesus, his work in Troas came to naught, and now, the Corinthians had been visited by missionaries they liked better than Paul. I'm not surprised Paul retreated back to Macedonia, near his most supportive congregation --- the Philippians.
