Leighton Pullan, The Books of the New Testament
“ Paul took so much interest. If Galatia be North Galatia, there is no such account in Acts. If it be South Galatia there is, and the polite and natural manner of addressing the inhabitants of the cities of Antioch, Derbe, etc., would be "Galatians." Their bond of union was association in one Roman province. (2) It is improbable that St. Paul would take the very difficult journey necessary for visiting the Celtic Galatians. His usual plan was to travel on Roman high-roads to the big centres of population. North Galatia was both isolated and half-civilized. ”
