In Birmingham, Alabama, Professor Richard Dawkins and his Oxford University colleague Professor John Lennox engaged in a lively debate over what is arguably the most critical question of our time: the existence of God. The debate centered on Dawkins' views as expressed in his best-seller, The God Delusion, and their validity over and against the Christian faith. Both presenters agreed to the format and topics of discussion.
I couldn't find an embeddable video of the debate, but you can view the entire debate at the following link:

After you watch the debate, be sure to go to the following link to hear a follow-up discussion between Dawkins and Lennox, which is perhaps more enlightening and more edifying than the debate itself:
Dawkins and Lennox Follow-up Discussion (audio)
I should also note that I don't know whether Dr. Lennox is a Catholic or a Protestant. However, I thought that everything he said was in line with the Catholic faith (both in the debate and in the follow-up discussion).
UPDATE: The original video link is working again, so I have re-edited the link to point to the correct URL. As of this moment, both of the above links are working.
