"“it is no uncommon thing to find [ancient writers] using [the name India] of countries such as Ethiopia, Arabia or Afghanistan. Indeed, except for those who had reason to be acquainted with our India, ‘India’ was a vague term which might stand for almost any religion beyond the Empire’s south-eastern frontiers.... To the fourth century Fathers India is the place of St. Thomas’s labours; but others, of earlier date, say Parthia, that is the Persian Empire stretching from North-West India to Mesopotamia; and of these the most notable is Eusebius the historian, who wrote in the fourth century. He says, ‘When the holy apostles and disciples of our Saviour were scattered over all the world, Thomas, so the tradition has it, obtained as his portion Parthia....’ Eusebius quotes as his authority for this statement the famous Alexandrian Father, Origen (ca. 185-254), thus carrying back the tradition to the first half of the third century. According to Origen and Eusebius, then, it was Parthia to which St. Thomas went. Moreover in another place Eusebius says that it was St. Bartholomew who went to India.... In what he says of St. Bartholomew Eusebius may well have in mind one of the countries bordering on the Red Sea.”"
