The following videos are from an appearance by Scott Hahn on the Catholic Answers Live radio program. He answered questions on several different topics, but several of the questions were related to evangelization. Dr. Hahn's answer in the final video is especially enlightening, regarding St. Paul's preaching in Athens, and what we can learn from it today.
I posted the first two of these videos earlier this year, but here are all of the available videos from this particular episode:
