what was Luke's gospel original language it was written in
A: Luke's Gospel was written in Greek Koine, a dialect of Attic Greek. This can be proven by comparing this gospel with Mark's Gospel, from which much of the material in Luke was sourced.The wordings are frequently identical in the Greek language, thereby proving that the original language was Greek.ther references in this Gospel indicate that it could not have been written much after 70 CE. So, we can say that Mark's Gospel was written in the late 60s or very early in the 70s CE. Luke could not have been written until some time after the 70s of the first century.
