The website of the Catholic Bishops Conference of England and Wales are posting a daily .mp3 meditation for Advent. These meditations have been prepared by Fr Peter Malone, a former president of SIGNIS - the World Catholic Association for Communication. Each meditation is linked to a film.
I haven't listened to any of the meditations yet, but thought to link to the relevant web page. This seems to me to be an interesting exercise in bringing religious faith into dialogue with our contemporary culture.
The page with the .mp3 files can be found here; the meditations are posted with the most recent post at the top of the page. Move down the page to find the earlier meditations.
