Ecclesiastical history (Philostorgius)/Epitome of book II

Chapter 6
The impious Philostorgius relates that the Christians in Central India, who were converted to the faith of Christ by the preaching of St. Bartholomew, believe that the Son is not of the same substance with the Father. He adds that Theophilus the Indian, who had embraced this opinion, came to them, and delivered it to them as a doctrine; and also that these Indians are now called Homeritae, instead of their old name of Sabaeans, which they received from the city of Saba, the chief city of the whole nation.
