My spouse and I lived in London, but we both come from (other) European countries, so for our wedding, three countries and four languages were involved: the church's forms are all both in the local language as well as in Latin.
This is no different than hundreds of years ago, and it works well. Thanks to Latin, the church's _lingua franca_.
I once heard someone say "English has replaced Latin as the Lingua Franca," and started giggling incoherently.
there is probably a joke about Jean-Luc Picard speaking proper King's English
