The chronology of Paul
For the chronology of Paul’s ministry, there are also some extra-biblical data: According to Josephus, Herod Agrippa I was made ruler of all Palestine by the emperor Claudius in ad 41 and reigned for three years. His death was thus in ad 44. A famine in Claudius’ reign took place when Tiberius Alexander was procurator of Judaea (c. 46–48), and Egyptian papyri suggest (by reference to high wheat prices) that the date of the famine was about 46. The Gallio inscription at Delphi (in Greece) gives a date for Gallio, proconsul of Achaia when Paul was at Corinth. It notes that Claudius was acclaimed emperor for the 26th time. This would bring the date of being declared emperor to about 52 and Gallio’s term of office (about one year) to about 51–52.
The chronology of Paul’s missionary journeys and the dates of his letters have been the object of an investigation made difficult by the fact that the account in Acts does not agree with Paul’s own letters, which are, of course, more reliable.
With the help of external references, some degree of absolute chronology might be sought—with several years’ margin both because of uncertainty as to extra-biblical dating and much ambiguity about internal evidence. Although Paul would be in a better position to know his own situation, often his letters are, in their present form, combined fragments from various times (see below The Second Letter of Paul to the Corinthians and The Letter of Paul to the Philippians). A chronology can be reached by comparing Paul’s accounts of his journeys and sojourns with those reported in Acts. Given references in Acts and the Gallio inscription, it is possible to place Paul in Corinth in ad 51, and, since he was there for 18 months, it can be assumed that he began his missionary work sometime in 49 (he had previously been in Thessalonica and Philippi and in Troas and Asia Minor). This probably fits in with the “expulsion” of Jews from Rome about ad 49, thus indicating that Paul met Priscilla and Aquila, two Roman Jewish Christians, in Corinth at this time. This indicates that he was at an “apostolic conference” at Jerusalem sometime shortly before this (a comparison of chapters 13 and 15 of Acts with chapters 1 and 2 of Galatians shows that the author of Acts made two visits out of the one recorded by Paul), which was either in 49 or 48.
Though the dates in Galatians 1 and 2 are uncertain—not indicating whether they refer to 17 years in toto or only 14 years, because half years were equated with whole ones—they do establish the call of Paul to become a Christian in 31 or about 34–35. Working in the other direction, it is known that Paul wrote to the Thessalonians from Corinth, thus indicating a date of about 50 as probable for the writing of I Thessalonians.
From Corinth, Paul went to Ephesus, where, according to Acts, he remained (probably in prison) for three years. This would place him in Ephesus during the period 52–55, thus allowing time for a journey from Corinth via Ephesus to Antioch and then back to Ephesus. A sequence given in Acts, chapters 16 and 18, shows two possibilities for Paul to have been in Galatia that work in agreement with Galatians, chapter 4, verse 13, demonstrating that Galatians was written from Ephesus about 53–54. Ephesus can also be the location from which came I Cor., Phil., and probably Philem.
II Corinthians appears to have been written from Macedonia during 55. From the dating of the periods of Felix and Festus in office at Caesarea (mid-50s) and from the events in Felix’ time of office, it is probable that Paul was in prison under Felix by 56.
Thus, data of Acts 18 and 20 regarding the journey and sojourn at Corinth can be correlated with data in Romans 15 to place the epistle to the Romans in about the year 56, before the journey back to Jerusalem, ending in the arrest of Paul in 56. The two years of Acts 24:27 can then be explained as the time during which Paul was in prison at Caesarea, so that in 58 Paul was before Festus and was sent to Rome.
That Paul was then in Rome for two more years is established in Acts chapter 28, verse 30. It can be concluded that Paul died sometime after 60, possibly during or before the Neronian persecution of 64 (cf. I Clem. 5). All this does not resolve the question of a possible Spanish journey nor give precise dates and locations for II Thessalonians, Colossians, Ephesians, or the Pastoral Letters (see also Paul).
