Fr. Robert Barron, who I've mentioned on here before, is a priest for the Archdiocese of Chicago and a professor at Mundelein Seminary. He has taken the lead on the new evangelization via YouTube and other services, and has a fantastic website: wordonfire.org.
Now, like Archbishop Sheen back in the day, Fr. Barron has a show on national television that discusses Catholicism and engages the larger culture. I saw his first show a few Sundays ago, and it was very well done! It is definitely worth a half hour on a Sunday morning. I believe the show starts at 10 a.m. eastern time - give it a look see.
