I am trying to figure out why it bothers me so much - I mean extremely - for gentiles to say Jewish prayers. I study with a group only two of whom are Jews. Periodically, someone will bring in a Jewish prayer, like the Shema, V'ahavta or Modeh Ani for instance, as in this morning. My skin crawls. I really want to stop them... vehemently. Is this because I am some kind of crazy, horrible elitist or is there some Jewish basis for this?
