Try Italian, which is still much closer to Latin than English.
So, when the Bishops from Nigeria, Malawi, Korea, Japan, etc. etc. come to Rome, they palaver in Italian?? I DON'T THINK SO! And I seriously doubt that the conversation around the coffee pot takes place in Latin, either. No, it'll be in English, just as with commerce in the rest of the known world.
To use a BAD non-sequitur---English is the "lingua franca" of today.
