Latin dominated the era in which Jesus lived because it was the language of the Romans whose empire... I think it was koine Greek, but what the heck.

Both wrong. The language of Jesus and the common Jewish people was neither Greek, nor Latin, nor Hebrew. It was something called Aramaic, the dominant language (99%) of the movie The Passion.

Aramaic was local; koine was the lingua franca of the Roman world, just as English is today, and Latin from the middle ages until recently.
