The common language spoken in the [[Holy Land]] at the time of Jesus was Aramaic. However, the original text of the New Testament was most likely written in [[Koine Greek]], the vernacular dialect in 1st century Roman provinces, and has since been widely translated into other languages, most notably, Latin, Syriac, and Coptic. (However, some of the Church Fathers seem to imply that Matthew was originally written in Hebrew or more likely Aramaic, and there is another contention that the author of the Epistle to the Hebrews wrote in Hebrew, which was translated into Greek by Luke. Neither view holds much support among contemporary scholars, who argue that the literary facets of Matthew and Hebrews suggest that they were composed directly in Greek, rather than being translated.)
It is notable that many books of the New Testament, especially the [[Gospel of Mark]] and the Book of Revelation, are written in relatively poor Greek. They are far from the refined Attic Greek or Classical Greek found composed by the higher classes, ruling elites, and trained philosophers of the time. Relative exceptions to this include the gospels of Luke and John and the [[Acts of the Apostles]].
