This is the first of 25 lectures on Historical Theology from the early church up to the Reformation. I have not listened to them all, but jumped around some; and still have a long way to go. Overall, it looks really good. See the side-bar on You Tube for the rest of the 25 lectures. He also has a Part 2 of Reformation and forward Historical Theology course. (see under the You Tube Page of The Master’s Seminary) I look forward to working through them.
Dr. Busenitz also has a book on Sola Fide, showing the earlier aspects and elements of the doctrine in church history before Luther. Called “Long Before Luther”.
PS. There is a also a course by Carl Trueman on the Reformation, there at the Master’s Seminary (Founder: John MacArthur) You Tube Page, that even a Roman Catholic like Alan Ruhl admitted was excellent.
