Perhaps He does, you see, exorcists will tell that the devil hates prayers said in Latin, he gets really riled. You can find accounts and read them.
Uh, no. What it says is that Satan has a special antipathy to Latin, not that God has a special affection for it. Or, it might just be that exorcists who work in the vernacular (if there are any) don't have valid holy orders. It would be interesting to see the track record of exorcists from Orthodox or Eastern Rite orders who use languages other than Latin.
