THE HISTORICAL PRECISION OF LUKE
Paul’s missionary companion, Luke, rejoined Paul at Philippi. Luke was a physician, missionary and the author of the gospel of Luke and the book of Acts. His presence, while not specifically named, is seen by a reappearance of the word, “we,” a second person plural unused since Acts 16.
Like John in his gospel, Luke doesn’t name himself, but does note when he is present in the story. Notice the detail that Luke gives. What time of the year? “After the Passover.” Where? “Philippi in Macedonia.” Destination? “Troas” (The ruins of”Troas” also called “Troy” are on the coast of modern day Turkey). How long? “Five days” on the ship and “a week” in Troas.
Apparently, Luke had remained at Philippi in the house of Lydia (See Acts 16:12), since they had first passed through the region. Why he remained there is not known. At any rate, Luke rejoined Paul at Philippi and continued with his precise historical record.
