In fairness, Father Reginald Foster, among the best Latinists at the Vatican and the leading one from the English speaking world, is a Marxist of the Maoist persuasion. He’s from Milwaukie, IIRC, and is certainly quite a character—but his Latin is hard to beat.
OTOH—almost certainly the working language of the document was either Spanish (more likely) or Italian. Even though JP II could do it in Latin, his drafts, IIRC, were often in Polish, and Pope Francis isn’t the linguist that JPII was.
IIRC & OTOH - is that some sort of new age pig latin?
