In the New Testament the book of Acts 13-28 describes the spread of Christianity primarily through the efforts of Paul and his companions. As they traveled throughout Asia Minor and Greece some Jews and many Gentiles adopted the new faith. Some of these Gentiles where already interested in the God of the Jews and involved in synagogue worship. This group is mentioned several times in the book of Acts (Acts 13:16, 26, 43; 17:4, 17).
Clear evidence for the presence of a Jewish population living at Miletus, which Paul stopped at on the return leg of his Third Journey (Acts 20:15ff), is evidenced by an inscription that is located on the fifth row of seats on the southeast side of the large theater at Miletus (see below).
τόπς Ειουδέων τῶν καὶ Θεοσεβίον
This inscription seems to mark “reserved seating” for Jews and possibly related “God–worshipers.” There are other “reserved seat” markings in this, and other, theaters. As it stands the inscription reads “the place of the Jews who are also God–worshipers.” But some have suggested that whom ever wrote the inscription may have inverted the “τῶν καὶ.” If this is the case, then the inscription could refer to two groups of people, Jews and Gentile God–worshipers (= “the place for the Jews and the God–worshipers”). Compare the same categories found in the book of Acts, although not quite the same terminology (Acts 13:16, 26, 43; 17:4, 17).
