My friend James Grant has posted a chart of a series of historical and biographical lectures by Dr. Nick Needham that have been made available Real Audio format at the website for The Wicket Gate magazine. These have been made available by the Reformed Baptist Church of Inverness, Scotland, of which, Dr. Needham is the pastor.
As many Protestants are more familiar with Church history from the time of the Reformation to the present, I would highly recommend the lectures on John Chrysostom (here and here) and Athanasius (here and here) from the Patristic era, and the lecture on Bernard of Clairvaux from the Medieval era. The lectures are full of helpful content, but what makes them even more attractive is Dr. Needham's great accent! Enjoy!
