Earlier quoted context omitted.
You mistake me. I'm not saying there's anything wrong with saying the mass in Latin. I'd kind of like to go see one! Put my 4 years of Jesuit Latin to use! But no, I don't think that's going to be a big draw for ordinary people to join the church. My Greek Orthodox friends growing up definitely spoke Greek!
It would definitely attract some people. An old friend of mine (from our Catholic high school), who almost never goes to Mass, told me he’d be willing to venture back if it were in Latin, just for the experience. We started looking into it, we were going to go together, but lost interest in the idea when we realised there weren’t any convenient to attend. I don’t know how common that attitude is, but I’m sure he’s no…
But again: drawing people isn't the point. Francis didn't crack down on TLM because he thought it was a bad way to get people to show up at mass! He did it because things in the church with TLM were getting weird. It's a doctrinal thing, not a marketing strategy.
