1) Arabic is just not their native language, so they have some difficulty to learn it. The vast majority of Christians does not either read the Bible in its original Aramaic, Hebrew and Greek. 2) "Arabic is the language of the Qur'an. Arabic is often associated with Islam, but it is also spoken by Arab Christians, Mizrahi Jews and Iraqi Mandaeans. Most of the world's Muslims do not speak Arabic as their native language but can read the script and recite the words of religious texts. Some Muslim speakers of Arabic consider their language to be "the language chosen by God to speak to mankind."" "Because the Quran is written in Arabic and all Islamic terms are in Arabic, millions of Muslims (both Arab and non-Arab) study the language. Arabic has been taught in many elementary and secondary schools, especially Muslim schools, worldwide. Universities around the world have classes teaching Arabic as part of their foreign languages, Middle Eastern studies, religious studies courses. Arabic language schools exist to assist students in learning Arabic outside of the academic world. Many Arabic language schools are located in the Arab world and other Muslim countries. Software and books with tapes are also important part of Arabic learning, as many of Arabic learners may live in places where there are no academic or Arabic language school classes available. Radio series of Arabic language classes are also provided from some radio stations. A number of websites on the Internet provide online classes for all levels as a means of distance education."
