Originally, during Jesus' time most people in the middle east (the place where Jesus lived) spoke the Semitic language. Especially Aramaic, which is similar to Arabic, so the language that Muslim religious leaders speak are more accurate than the pope's. On my opinion, I think it doesn't matter what language you speak to god, just as long as your praying. But, all I want to know is why does the people of the roman catholic church have to speak Latin?
