The third part of In the Footsteps of Jesus was broadcast at 8 pm GMT today (I managed to catch it live today, from my office at Duke). As usual, you can listen on-line if you missed it. At this stage, the website is showing the wrong URLs for transcript (broken) and episode (link is to part 2), but the main Radio 4 website has the correct link:
In the Footsteps of Jesus, 5 December
Today's is set in Rome and features a lot of Gerald O'Collins and snippets of Tom Wright and Bart Ehrman, among others.
