Which journeys with Paul may St. Luke have taken?

In Christian tradition, St. Luke is considered a companion of St. Paul the Apostle who accompanied him on several missionary journeys. This association is primarily inferred from the "we-passages" in the Acts of the Apostles, which shift to the first-person plural, suggesting the author's presence during specific travels.12

Based on these accounts, Luke may have participated in the following journeys:

• Initial Mission to Greece: The narrative places the author with Paul during his first mission into Greece, specifically as far as Philippi in Macedonia (c. 51 ce).1
• Final Journey to Jerusalem: Luke is described as rejoining Paul to accompany him on his final trip to Jerusalem (c. 58 ce).1
• Prison Voyage: Two years after Paul’s arrest in Jerusalem and his detention in Caesarea, Luke appears with Paul on his voyage to Rome.1
• Final Days: According to the Second Letter of Paul to Timothy, Luke was present with Paul at the time of the apostle's martyrdom in Rome (c. 66 ce).1

While these traditions are widely held, some scholars note that the "we-passages" may be a stylistic literary device common in ancient travel reports rather than definitive proof of Luke's physical presence.12
