Did Paul mean by Galatia the Roman province as he usually does or does he make an ethnographic use of the term and mean the real Celts of North Galatia? Luke uses geographical terms in either sense. Certainly Paul preached in South Galatia in his first mission tour. See note on Act 16:6 for the discussion about the language there as bearing on his going into North Galatia. By “the churches of Galatia” Paul can mean the whole of Galatia or either South or North Galatia. The various items mentioned, like the illness that led to his preaching (Gal 4:13), “the first time” or “formerly” (Gal 4:13), “so quickly” (Gal 1:6), are not conclusive as to time or place. If Paul means only the South Galatian Churches (Pisidia, Lycaonia, Phrygia), then the Epistle, even if two visits had been made, could come some time after the second tour of Act 16:1. The place could be Philippi, Corinth, Ephesus, Antioch. Even so room must be made for the seventeen years after his conversion plus the interval thereafter (some twenty years in all). If Paul includes North Galatia, the time would be more easily handled (the twenty years required from a.d. 31 to 36 to a.d. 51 to 57) and the place could be Ephesus, Philippi, or Corinth. Special treatises on the date of Galatians have been written by Askwith (1899), Round (1906), Steinmann (1908), Weber (1900)

Lightfoot held that the similarity of Galatians to Romans (written from Corinth spring of a.d. 56 or 57) naturally argues for the same general period and place. It is a possible hypothesis that, when Paul reached Corinth late autumn or early winter of A.D. 55 or 56 (Act 20:1.), he received alarming reports of the damage wrought by the Judaizers in Galatia. He had won his fight against them in Corinth (I and II Corinthians). So now he hurls this thunderbolt at them from Corinth and later, in a calmer mood, sends the fuller discussion to the church in Rome. This hypothesis is adopted here, but with full recognition of the fact that it is only hypothesis. The language and the topics and the treatment are the same that we find in Romans. Galatians thus fits in precisely between II Corinthians and Romans. It is a flaming torch in the Judaizing controversy. This Epistle was the battle cry of Martin Luther in the Reformation. Today it has served as a bulwark against the wild criticism that has sought to remove the Pauline Epistles from the realm of historical study. Paul is all ablaze in this Epistle with indignation as he faces the men who are undermining his work in Galatia.
