That defi will come as a severe shock to Christian Galilaeans and to any number of Maronite and Nestorian Christians. Believing it would make it nearly impossible to understand how Christians in India came to practice their liturgy in Syriac. My sister got married in this language 25 years ago, in a church Christianized 17 centuries previously by St. Thomas of India, who followed the Roman trade routes to take up a mission in the Greek trading entrepots of the Malabar Coast.
No, that won't be a shock to any Maronite or Nestorian. Why do you think they have been persecuted by the majority of Jews and Arabs for the past 2000 years? The number of Maronites is very small compared to the number of semetic Muslims. And the Nestorians are very small. And Christianity never took root in India no matter what language the litergy is in.
Christianity did originate among a Semitic people, but it never took deep roots among Semites. Most Jews never converted and never will. And when Islam came along, a form of religion conforming more to Semitic cultural values, it easily supplanted Christianity. Christianity is a minority religion among Semitic peoples. Among them, Islam and Judaism predominate.
