Christian debater Luis Dizon posted a pic of some Greek and Hebrew grammar books. Cheekily I sent him a tweet saying “accept Jesus spoke Aramaic! Yet you will doubtless not be studying the language of Jesus himself.” He replied:
So with the exception of a few stray Aramaic phrases in the gospels, we cannot know for sure what Jesus actually said. Greek (the language of the gospels) is a very different language to Aramaic (the spoken language of Jesus). As different as modern English is to Arabic. All translation is interpretation and we always lose something of the original in translation. Fortunately we do not have this problem with the Qur’an and hadith which are studied in their original languages.
