About a week ago I "discovered" Father John Riccardo of the Archdiocese of Detroit.
Resembling in some ways Father John Corapi and in others Archbishop Fulton Sheen, Father Riccardo is a highly orthodox, thoroughly lucid and remarkably humble expositor of the faith.
See for yourself ...
Dozens of Father Riccardo's homilies and longer talks can be found here.
I found myself particularly impressed with his series of talks entitled Catholicism for Cradle Catholics, especially number 7 on the Eucharist.
Also, his Faith Under Attack is a must listen for anyone with children - or grandchildren - about to head off to college.
UPDATE: Most of the talks on Father Riccardo's site are in audio format but there are a few videos. One of these, Confession: A Fireside Chat with the Lord, is well worth the 30 minutes it takes to watch it.
