Carlo Carletti, an archaeology professor at the University of Bari, said that the starting point for any examination of the topic is Romans 16:1, in which St. Paul refers to “our sister Phoebe, a deaconess.”
Of the 30 inscriptions that refer to deaconesses, said Carletti, 25 have been found in Asia Minor (in modern-day Turkey).
Carletti attributes this geopraphical concentration to the legacy of St. Paul, who included women in his missionary activity.
In the West, on the other hand, “the diaconal ministry … remained constantly a male prerogative.”
