I ran across this today, so I’m posting it.
Fr. Coulter has posted audio files of all of Pope St. Leo the Great’s sermons, read in Latin by Fr. Reginald Foster. Fr. Foster is the guy who was the papal Latinist, until ill health and frailty made him retire.
Fr. Coulter has also posted a lot of other info and resources from Fr. Foster’s justly famous Latin “experiences” or classes.
