AnswerMany Christians believe Paul's last journey was the journey as a prisoner to Rome, described in Acts of the Apostles. However, there is no mention in the undisputed (or even the pseudonymous) Pauline letters of the appeal to Caesar and the journey to Rome, and some dismiss the account of Paul's hazardous sea journey in Acts as novelistic fiction.
Another source, 1 Clement, written around the same time as Acts or perhaps a little earlier, reports that Paul "travelled to the extreme west" (
Spain), before he bore witness to the ruling authorities and died.
So, we have two different sources, both written decades after the time of Paul, with one saying that his last journey was to Rome, while the other says that his last journey was to Spain. While there is no reason to expect Paul's extant epistles to mention the final trip to Spain, if indeed it did occur, it is a little surprising that there was no confirmation of the final journal to Rome, if this account was correct.
We can choose to believe that Paul's last journey was either to Rome or to Spain, but we can not be certain. It may even have been to yet another destination.
