It is not the name itself that is bizarre, Yeshu'isiam, it's the ideology behind it. Nobody will tell the Syriacs, for instance, not to pray in the name of Moran 'Isho Mshiho, but likewise there is no reason why it should be necessary that anyone outside of that tradition adopt Aramaic or Syriac posturing in their prayer just because of some strange need for "authenticity". It is Christ and the religion of Christianity itself that is authentic. This is after all as the Byzantines put it, the faith that established the universe. Given that fact, it shouldn't even be debatable that it is in fact authentic in Greek, and Latin, and Inuktitut, and Mongolian, and Tlingit, and German, and Walloon, and whatever other language just as much as it is in Aramaic, Syriac, Coptic, Ancient Greek, or any other more traditional language of worship. Lose sight of that and you risk making Christianity into a fetish in the worst possible meaning of that term.
