<P> The original texts were written in the first century of the Christian Era , in Greek , which was the common language of the Eastern Mediterranean from the conquests of Alexander the Great ( 335 -- 323 BC ) until the Muslim conquests in the 7th century AD . All the works that eventually became incorporated into the New Testament are believed to have been written no later than around 120 AD . John A.T. Robinson , Dan Wallace , and William F. Albright dated all the books of the New Testament before 70 AD . Others give a final date of 80 AD , or at 96 AD . </P>
