Question
If Matthew truly wrote Matthew, why would he use a Greek translation of the Torah?
Response
It seems that there are really two questions here:
- Why did Matthew use a Greek Translation of the scripture, and
- Did Matthew really write Matthew?
The second question, I address in summary way in another post on this blog.
Regarding the first question, I believe Matthew wrote in Greek and used a Greek translation of the Torah so that it could be read by a wider audience. At this point, Greek was the common business language of the Roman empire.
