Homilies are not given in Latin.
When we cheer Latin we are talking about the prayers which have been intentionally mistranslated so as to give them a different meaning.
If you attend a Tridentine Mass you'll notice that the readings and homily are in the vernacular. Similarly, in the Novus Ordo, Latin will add great unity especially in America where so many languages are spoken in the same city.
I more strongly suspect that you know all this and are intentionally trying to confuse the issue.
Yes, what a shame that we cannot have Latin Masses, where the readings are done in English and Spanish for example, rather than bifurcate the parish into English and Spanish masses.
Why, on God's earth, would I be trying to confuse any issue?
